How Ivuna women farmers are transforming their lives through seed production

“Five of us borrowed $100 from our Vikoba group and invested it in seed production. Not only did we repay the loan with interest, but we also made a profit,” says Skola Sichalwe, a member of an extraordinary group of women who are transforming their community in Ivuna Village, Momba District. Vikoba groups, grassroots savings and credit associations, operate as informal microfinance systems in rural communities, empowering members with access to small loans and promoting financial independence. These groups often provide a lifeline for women seeking financial stability and growth in rural areas. What began as small savings groups has blossomed into a powerful movement of women breaking barriers and creating a legacy of resilience, innovation, and success. These women—once skeptical about venturing into seed production—are now thriving entrepreneurs, producing quality sorghum seeds and inspiring others in their community to follow their lead. Their journey began with a chance encounter with Miss Zainab Hussein, a passionate seed producer and a youth champion. Her vision and mentorship planted the first seeds of change. “I used to think farming was just about survival,” says Pauline Martin. “But Zainab showed us that with the right knowledge and tools, farming can be a business; a way to change our lives.”

A leap of faith in seed production

Before venturing into the world of seed production, these women were members of Vikoba groups, pooling their savings to lend and borrow money. While this system was helpful for meeting immediate financial needs, it offered little opportunity for growth or long-term investment. Everything changed when Zainab Hussein, an experienced seed producer and youth champion, began attending their meetings. Zainab introduced the group to the potential of improved seeds and the opportunities in seed production. She explained how adopting high-quality sorghum seeds could significantly increase yields and profits, far exceeding the returns from what traditional grain farming could offer. Her visits became a game changer, sparking curiosity and inspiring action among the women. “Zainab’s dedication inspired us,” says Skola Sichalwe. “She didn’t just train us. She believed in us.” As a trainer, mentor, and role model, Zainab played a central role in their transformation. She guided the women through the complexities of seed production, teaching them essential planting techniques, helping them understand TOSCI regulations, and offering practical solutions to challenges they encountered along the way. “She showed us how seed production could not only improve yields but also become a profitable business,” recalls Pauline Martin.

Inspired by Zainab’s success, the women saw an opportunity to turn their savings into a sustainable investment. This journey was further supported by the establishment of Youth and Women Quality Centers (YWQCs) under the Center for Behavior Change Communication (CBCC) and the Accelerated Varietal Improvement and Seed Systems in Africa (AVISA) project through CIMMYT. The AVISA project, led by CIMMYT, piloted the YWQC model to address key challenges faced by rural farmers, including limited access to quality seeds, market linkages, and knowledge on improved farming practices. These community-led centers serve as hubs that enhance last-mile seed access by working with seed companies and local producers, ensuring a consistent supply of quality seed. They also facilitate market linkages by connecting farmers with aggregators and off-takers, improving market access and profitability. Additionally, YWQCs provide capacity-building initiatives, equipping youth and women with training in farming practices, local seed production, and business skills. The model further promotes collective action by encouraging farmers to form associations, strengthening their bargaining power and collective marketing efforts. These centers became hubs of opportunity, providing essential infrastructure and resources such as access to certified seeds, extensive training, and advanced farming technologies such as the multi-crop thresher through a cost-sharing arrangement. This technology not only improved efficiency but also ensured the quality of processed seeds, increasing its market value. The project also facilitated crucial linkages between the women and certified seed producers, ensuring they had access to high-quality inputs for their production. In some cases, the project even helped them find markets for their seeds, closing the loop and creating a sustainable business model. And so, they began the journey of seed production, transforming not only their own lives but also their community.

With loans from their Vikoba groups, they purchased quality seeds and accessed the tools, training, and market linkages provided by the YWQCs. “For years, we saved money but didn’t know what to invest in,” says Halima Kajela. “Seed production gave us a clear opportunity to grow.”

Challenges: A Test of Determination

The journey wasn’t without hurdles. Rodents feasted on the carefully spaced sorghum seeds, a new planting method the women had to adopt for certification. “Broadcasting seeds was easier, but seed production required precise planting and spacing,” Halima explains. “This made it harder to protect the seeds from pests and animals.” Excessive rain washed away seedlings, requiring several rounds of replanting. Cattle from neighboring farms often invaded their fields, causing further damage. Adopting good agronomic practices such as proper spacing, timely weeding, and regular inspections was initially difficult for these women, who were unaccustomed to the disciplined approach required in seed production. Despite these setbacks, the women persevered. With Zainab’s guidance and support from the YWQCs, they implemented solutions like using seed planters which saved time and effort during planting, knapsack sprayers helped combat pests and diseases, and multi-crop threshers simplified the post-harvest process. All these tools saved time and improved efficiency.

Triumph in the fields

And their hard work paid off. In their very first season, the women achieved remarkable success, producing three tons of TARISOR 2, an improved sorghum variety. This achievement not only set them apart from other first-time producers in the district, but also marked the beginning of a transformative journey.

The impact of their efforts went far beyond the impressive harvest. Ten women became officially registered seed producers with the Tanzania Official Seed Certification Institute (TOSCI), gaining recognition and credibility in the seed production business. Two members received specialized training in seed and fertilizer dealership, equipping them to expand their services and outreach to the community. Four women ventured into distributing essential agricultural inputs, such as maize seeds and hermetic bags, further diversifying their income streams and supporting local farmers. Recognizing the need for efficient post-harvest processing, the group collectively contributed to the purchase of a multi-crop thresher. This crucial investment significantly streamlined their operations, reducing labor and ensuring higher-quality processed seeds. Their efforts quickly translated into financial rewards. Within a short time, they sold one ton of their high-quality seeds, earning over $700. As word of their success spread, demand for their seeds continued to grow, promising even greater opportunities in the seasons ahead.

A ripple effect of change

Their success has had a profound effect on their community. The women’s achievements have earned them respect, and their influence is inspiring others to follow in their footsteps. “Before this, I didn’t believe in seed production,” says Pauline. “But after seeing Zainab’s success and what we achieved, even my husband now supports me fully in this venture.” Their impact extends beyond their fields. Other Vikoba groups have invited them to share their knowledge on seed production, and 10 new women have expressed interest in joining the initiative. By making improved sorghum varieties more accessible, they’ve also helped increase production and reduce food insecurity in their village.

Looking ahead: Planting seeds for the future

Inspired by their success, the women have ambitious plans. With a clear vision for the future, they are determined to expand their seed production enterprise and bring its benefits to a wider community. One of their primary goals is to extend their production to neighboring wards, such as Mkomba. To make their knowledge and improved seed varieties more accessible, they plan to establish demonstration plots closer to the village center. These plots will serve as practical learning sites, allowing more farmers to experience the advantages of using certified seeds and adopting best practices. “The demand for quality seeds is growing,” says Halima Kajela, one of the group members. “We’re committed to meeting that demand and helping more farmers improve their yields.” They are also exploring ways to diversify their operations. They aim to invest in distributing other agricultural inputs and post-harvest services such as threshing, to support farmers in the community and generate additional income. For these women, seed production isn’t just a business—it’s a symbol of empowerment.

Agricultural stakeholders devise means to tame effects of soil acidity

Agricultural stakeholders in Tanzania, including CIMMYT, are preparing to implement a major project to combat soil acidity, affecting 32.7 million hectares of land. Led by the Tanzania Agricultural Research Institute (TARI), the initiative aims to improve crop production by promoting the use of agricultural limes and enhancing soil health management. This effort is part of the GAIA project, focusing on equipping farmers with essential agronomic knowledge to boost yields and productivity.

Accelerated delivery with a difference is underway in Malawi, Tanzania, and Zambia to ensure access to stress-tolerant seeds for underserved farmers in remote areas. Supported by USAID, the Accelerated Innovation Delivery Initiative (AID-I) project brings public-private and civil society together to address the impacts of climate change, pests and diseases, and food shocks on maize and legume systems.

One simple and cost-effective solution to tackle these threats is last mile delivery of stress-tolerant and nutritious seeds. Ensuring that farmers have access to a diverse range of seeds means they can choose the best varieties to suit their needs and their local environment.

Through AID-I, scientists at the International Maize and Wheat Improvement Center (CIMMYT) are working with over 20 global, regional, national, and local partners to strengthen maize and legume seed systems in Malawi, Tanzania, and Zambia.

So far, in 2023, the team has set up over a hundred mega-demonstrations across Malawi and Zambia, to raise awareness and increase seed production by exposing communities to improved, climate-adapted and nutritious crop varieties. As learning centers, the mega-demonstrations give farmers a chance to see for themselves the advantages of improved maize and legume varieties and better farming practices including conservation agriculture and doubled up legumes systems.

Spotlighted were drought-tolerant and nutritious varieties, expected to play a crucial role in the recovery of regional maize production. The Zambian and Malawian governments have also just released maize hybrids tolerant to fall armyworms, which will be scaled through the AID-I. The fall armyworm is an invasive pest that attacks more than 80 different crops but has a particular preference for maize. Without proper control measures, the pest can decimate crops, threatening food security, incomes, and livelihoods.

Alongside maize, the AID-I team is making seed of improved legume varieties, including beans, soybean, pigeon peas, cowpea, and groundnuts available at the last mile. Legumes are nutritious and good for the soil, providing valuable nutrients like nitrogen (N) so farmers can use less fertilizer, save money, and protect soil health.

AID-I supports strengthening of strategically located seed stockists of improved legume varieties and linking seed growers and buyers. These stockists, called agricultural development agents will also receive training in community seed production. Through connection with hundreds of agricultural development agents in the first farming season with seed suppliers, hundreds of thousands of farmers will be able to access a wide variety of improved seed.

Building strong relationships between public and private sector organizations is an integral part of the project. On January 16, 2023, long-term CIMMYT collaborator and AID-I key partner, AfriSeed hosted senior government officials from the United States Department of State (DOS) and U.S. Agency for International Development (USAID). The visitors gained valuable insight into how private seed companies involved in the marketing and distribution of maize and legume seeds operate in Zambia and showed their crucial role in the country’s seed sector.

Private sector support essential for agribusiness

On February 7, Samantha Power, Administrator for the United States Agency for International Development (USAID), visited SEAN Seed Service Centre (SSSC) in Thankot, Nepal. Her time at the seed company — which is supported by the Nepal Seed and Fertilizer (NSAF) project — provided an opportunity to learn more about how private sector support for agribusiness can help accelerate Nepal’s agricultural transformation.

The event began with a tour of the company’s facilities and seed lab, where Power met with breeders and employees responsible for sorting and grading seeds. Other stops on the visit included meetings with SSSC management and researchers from the International Maize and Wheat Improvement Center (CIMMYT), who explained the important role the private sector plays in the country’s seed sector, from the development of climate stress tolerant varieties to facilitating seed access and distribution.

Later in the day, Power participated in a round table discussion with agribusiness entrepreneurs from seed and agricultural production companies, fertilizer manufacturers and distributors, and farmers cooperatives to better understand the key challenges and opportunities in fostering agricultural transformation in Nepal. The talks focused on the need for reforms on seed and fertilizer markets and elimination of market distorting policies such as unplanned subsidies, as well as the need to facilitate access to finance to boost investments and insurance to manage risks.

Key recommendations from participants included increased use of technologies — such as improved seeds, machineries, improved soil fertility management and digital tools — as well as the creation of a more enabling environment for attracting private sector investment and increasing agricultural participation among youth and disadvantaged communities in Nepal. The private sector plays a critical role in bolstering national food security, increasing economic growth, and creating transformative change in the country’s agricultural sector so it can be more commercial, competitive, and inclusive. Participants provided suggestions on how the Government of Nepal could further support the sector, allowing agribusinesses to develop and grow in order to cater to the needs of smallholder farmers and consumers.

CIMMYTs Nepal Seed and Fertilizer (NSAF) project is funded by the United States Agency for International Development (USAID). It aims to develop competitive and vibrant seed and integrated soil fertility management (IFSM) systems for inclusive and sustainable growth in agricultural productivity, business development, and income generation in Nepal.

Building capacities in genetic resources and seed production strengthens collaboration ties between Guatemala and CIMMYT

More than 20 participants attended the genetic resources and seed production courses given by researchers from the Global Maize Program of the International Maize and Wheat Improvement Center (CIMMYT), from October 24 to 28 in Antigua, Guatemala. Among the attendees were technicians and researchers from the Institute of Agricultural Science and Technology (ICTA, for its acronym in Spanish), as well as students from Universidad Rafael Landívar and the University Centers of Chimaltenango (CUNDECH, in Spanish) and Quiché (CUSACQ, in Spanish) of Universidad de San Carlos de Guatemala.

Thanks to the support of the Global Environment Facility (GEF), the Tropical Agricultural Research and Higher Education Center (CATIE, in Spanish), the National Council for Protected Areas (CONAP, in Spanish) and the United Nations Environment Program (UNEP), these courses contributed to the development of a biosafety project, supported by GEF and UNEP, to complete the implementation process of the Cartagena Protocol through an innovative approach that promotes a strong link between biotechnology and biodiversity. In addition, it sought to strengthen capacities in the performance and interpretation of molecular analyses and promote the generational change that is gradually taking place in this Central American country.

Activities began on October 24 and 25 with the course on Statistics Applied to Genetic Resources given by Juan Burgueño, Head of CIMMYT’s Biometrics and Statistics Unit, to students from the aforementioned universities and ICTA staff interested in the analysis of molecular data for the purpose of characterizing accessions and the formation of core collections in germplasm banks. On the 26 and 27 of the same month, César Petroli, a specialist in high-throughput genotyping at CIMMYT, offered a course on biotechnology and high-throughput genotyping.

At the same time, Alberto Chassaigne, curator of the Maize Collection of CIMMYT’s germplasm bank, participated in the course on Genetic Resources and Management of Germplasm Banks. He explained the management of CIMMYT’s germplasm bank, the processes that are carried out and the partnerships with ICTA on work with community seed banks and the plans of both institutions for 2023. Also, as a specialist in Seed Systems, Chassaigne and Ubaldo Marcos, research assistant in CIMMYT’s Maize Seed Systems area, gave a course on Maize Seed Production. This course was aimed at staff in charge of the production of basic and certified seed at ICTA. This course concluded with a field day at the Regional Research Center of the South (CISUR, in Spanish), Cuyuta, Escuintla, where participants asked the specialists questions while visiting a maize seed production plot.

In turn, María de los Ángeles Mérida, a researcher specializing in genetic resources from ICTA, who organized these courses, spoke about the collection and conservation of native varieties of maize in Guatemala. Additionally, César Azurdia, CONAP biodiversity advisor, gave a presentation on wild relatives of different crops in Guatemala. Leslie Melisa Ojeda C. (CONAP) also participated, and spoke about the issue of legislation on crop wild relatives; and, Mynor Otzoy, a researcher from Universidad de San Carlos de Guatemala, spoke about the collection and morphological characterization of cocoa germplasm in Guatemala.

Along the path of constant strengthening of collaboration ties with countries, course participants highlighted their interest and need to continue this type of training. In 2023, it is expected to facilitate a team training with Ubaldo Marcos and Félix San Vicente, CIMMYT maize breeder for Latin America. It should be noted that, within the framework of the CGIAR germplasm bank initiative, the objective will be to replicate this experience in other Latin American countries and increase participation in community seed banks (ex situ and in situ banks).

Strengthening capacity and building national and regional partnerships in the seed sector

Hybrid seeds exhibit a significant potential to boost on-farm productivity and attain food security. Still, the availability, affordability and accessibility of such quality seeds remain a challenge for farmers in South Asia. Primarily driven by the demand from the poultry industry, maize productivity in the region is increasing annually. Yet, the hybrid maize seed coverage is below 50% in most South Asian countries.

In continuation of its capacity-building initiatives, the International Maize and Wheat Improvement Center (CIMMYT) conducted an International Training Workshop on Quality Hybrid Maize Seed Production and Seed Business Management in South Asia on August 15-18, 2022, in Kathmandu, Nepal. The four-day hybrid training was jointly organized by Nepal’s Seed Quality Control Center, Nepal Agricultural Research Council (NARC), Seed Entrepreneurs’ Association of Nepal and CGIAR’s Seed Equal Initiative. Primarily, the event aimed at strengthening the capacity of seed stakeholders on the latest advances in quality hybrid maize seed production and establishing competitive hybrid seed business strategies.

Around 60 participants comprising of private seed company owners, national and international seed system specialists, maize breeders, crop inspectors, seed agronomists, marketers, policymakers and researchers working in hybrid seed production and marketing attended the training. Representatives were invited from Nepal, India, Bangladesh and Pakistan.

Principal trainer, John MacRobert, shared examples and knowledge in the principles of hybrid maize seed production and seed business. Former principal scientist of CIMMYT, MacRobert is currently the managing director of Mukushi Seeds Pvt Ltd in Zimbabwe and director of Quality Seed Pvt Ltd in South Africa. The training also involved group discussions and exercises on preparing a seed road map as well as developing profitable seed business plans. The participants used a seed business model canvas tool to chart their production plans, develop marketing strategies and diagnose profit. In 2018, MacRobert trained 15 private seed companies from Nepal and Pakistan on hybrid seed business mentorship course in Kathmandu. Since then, the participants brought in and shared rich practical experiences from their own businesses and regulatory organizations during this year’s program.

Joining MacRobert were 14 national and international experts from CIMMYT and other institutions, who delivered sessions related to hybrid maize breeding principles and techniques, seed quality control measures and regulations, and variety registration and licensing policies and procedures.

The forum offered an excellent learning opportunity for the national and international participants to exchange knowledge and experiences from seed specialists on developing competitive hybrid maize and seed production technologies that will bring cost-efficiency in production and maximize crop yields and business profits. It also served as a ground for establishing networks and collaborations. The mutual learnings will contribute to building national and regional partnerships in the seed sector.

Participants reflected on the learnings and benefits gained from the comprehensive course, which they would apply to improve maize productivity in their respective countries.

Muhammad Aslam, assistant professor from the University of Agriculture Faisalabad in Pakistan, acknowledged the opportunity provided to him and his university. He mentioned the support of CIMMYT in Pakistan in strengthening the local maize seed industry, where the market share of local seed companies is gradually increasing due to the elite germplasm support and capacity development efforts by CIMMYT. He added that the practical knowledge gained from the training will enhance the university students’ skills.

An ode to seeds

During the closing session of the training, Govinda Prasad Sharma, Secretary of the Ministry of Agriculture and Livestock, handed over diverse maize seeds to the NARC and seven private seed company partners of the Nepal Seed and Fertilizer (NSAF) project. CIMMYT acquired the elite maize parental lines and breeder seeds from its international maize breeding hubs in Mexico, Zimbabwe, Colombia and India. The seeds have the potential of yielding 6-7 metric tons per hectare for synthetics and more than 10 metric tons for hybrids–a significant increase from 3-5 metric tons of local seeds. More importantly, given the current climate challenges Nepali farmers are facing, these climate-resilient seeds reach maturity earlier than local varieties which reduces their exposure to drought. These seeds will also withstand Fall Armyworm infestations, a devastating pest threatening maize production in Nepal.

“Genetic materials that will not only enhance yield but diversify the gene pool of crops in Nepal is extremely important,” said Lynn Schneider, deputy director of the Economic Growth Office at United States Agency for International Development (USAID) Nepal. “Agriculture must combat climate change and malnutrition, which are critical for the South Asia region. So, I am really proud that we are working on these areas,” shared Schneider.

“Food security is a priority for the Government of Nepal,” explained Sharma. He mentioned maize as an essential commodity from the food and feed perspective for South Asia and plans to collaborate with the private sector and donor organizations to increase maize productivity in the country. “The event will definitely help in augmenting the activities and accelerate the pathway towards achieving food and feed security,” he added.

Moreover, a certificate of appreciation was presented to Nepal’s National Maize Research Program to recognize their effective collaboration in hybrid maize varietal promotion and source seed distribution. Similarly, three partner seed companies of the project were also recognized for the breakthrough in becoming the first recipients of the Government of Nepal’s research and development license to register and produce hybrid seeds on a commercial basis.

CIMMYT also launched an assessment report on Cereal Seeds Value Chain in Nepal that provides evidence-based recommendations for developing Nepal’s formal cereal seed sector, specifically maize and rice. The publication highlights the need for a well-performing seed system where high-quality seeds of a wide range of varieties and crops are produced and available in time and affordable to farmers.

Deepak Bhandari, executive director of NARC, also congratulated the authors and expressed the significance of formulating and implementing inclusive strategies to build a vibrant seed industry in Nepal. He also acknowledged the event organizers for conducting an exceptional international workshop on hybrid maize seeds for the public and private seed stakeholders.

Cereal seed systems

For certified seed to reach a farmer’s field for cultivation, it passes through many hands – international and national breeding programs, government regulatory agencies, private seed companies, and retailers or agrodealers. These organizations each play an important role in the design, testing, production and distribution of improved maize and wheat varieties.

Together, these processes, actors, and the relationships between them form a seed system, which incorporates the production, conservation, exchange, and use of propagation materials for crops. As defined by the CGIAR Community of Excellence for Seed Systems Development (COE), seed systems are complex, involving arrangements between public and private sectors, layers of regulation, and years of research and development, and are specific to each crop, country, agroecological environment and market context.

The International Maize and Wheat Improvement Center (CIMMYT) has extensively researched and worked with the facets and actors of cereal seed systems in Latin America, Asia and Africa, specifically in relation to cereal crops, and with maize and wheat in particular.

The role of CIMMYT scientists in supply and demand

Breeding teams use traditional and advanced techniques to identify improved maize and wheat breeding lines according to the desired traits determined by farmers and consumer markets. In addition to higher grain yields, other preferred traits include more and larger grains or fruit, resistance to pests and diseases, tolerance to environment pressures (such as drought or poor soils), better nutritional quality, or flavor and ease of processing.

These lines are used for further breeding, testing, seed multiplication by public and private sector partners. Others engage in varietal testing on farmers’ fields and support seed companies in production.

To foster smallholder farmers’ access to these improved varieties, CIMMYT implements a seed systems strategy divided into supply side development, concerning breeding and seed production, and demand side development, covering issues related to variety distribution and uptake. On the supply side, CIMMYT scientists’ work is carried out in three phases:

  • Product development phase: Breeders advance through CIMMYT’s breeding funnel (pipeline) the most promising materials from one improvement stage to the next. The best candidates are first tested in field trials at research stations and then in farmers’ fields. Afterwards, CIMMYT organizes field days to showcase the best performing materials to public and private sector partners.
  • Product allocation phase: Local partners request new CIMMYT products and sign licensing agreements that protect the new seed from private ownership claims and help accelerate marketing and distribution in target regions at affordable prices.
  • Release and commercialization phase: Farmers can obtain and benefit from seed of improved maize and wheat once national authorities register and release varieties that excel in national performance trials and public and private sector partners begin seed production and marketing or distribution.

On the demand side, CIMMYT scientists work to support seed systems development though its work on:

  • Farmer preferences and demand for varieties: Scientists look to understand current and future preferences and needs for varieties. This involves the use of innovative tools, such as product concept testing, on-farm testing and ranking, and participatory varietal evaluation.
  • Seed industry development: Small and medium sized seed businesses, as well as agrodealers, play a critical role in the distribution of seed. Our work looks to understand entry points for support to the seed industry for advancing faster uptake of new varieties by farmers.
  • Consumer demand for grain: The preferences of consumers and agroindustry for grain and grain-based foods provide an important source of demand for new varieties. CIMMYT scientists engage with consumers and agroindustry for innovation in food product design and testing consumer acceptance. Insights gains are reported back to breeding and seed production teams for design of future cereal varieties.

Gender-sensitive seed systems

A team of social scientists at CIMMYT with expertise in economics, gender and marketing works to understand the needs and preferences of farmers, consumers, and the agroindustry for new varieties. They develop retail strategies, such as targeted marketing, in-store seed assessment support and price incentives, promote the adoption of better policies in support of seed companies and seed markets.

CIMMYT explores mechanisms to help seed companies adapt their products to women’s preferences. Research shows that beyond yield potential, women seek different characteristics in seeds than men. For example, women are more inclined to favor a variety with a longer grain shelf life. Similarly, when women engage in participatory variety selections, they tend to make more objective evaluations of varieties than men.

Our experts advance strategies to promote inclusive and effective delivery systems, helping both female and male farmers obtain the seed that works best for their specific needs. This ongoing model gives CIMMYT feedback from farmers and public and private sector partners, which informs subsequent breeding research.

Why are cereal seed systems important?

CIMMYT contributes to new improved seeds getting to farmers, consumers and agroindustry, which ultimately leads to lasting positive impacts in terms of food security and economic development.

Cereals such as maize and wheat play a critical role in global food security. Increasing their productivity in the Global South remains a key developmental priority. Smallholders face increasing pressure to sustain and increase their yields in the face of three main issues: climate change, which increases the frequency of severe drought, floods, and pest and disease outbreaks; rapidly rising costs of inputs, such as land, labor, fertilizer; and unfavorable marketing conditions for their grain.

As a critical entry point for improved agricultural technology, seed systems are in urgent need of improvement and modernization. Since the onset of the Green Revolution in the 1960s, the discovery, development, and delivery of improved seed for smallholder farmers has remained an essential part of global and local initiatives to increase smallholder productivity.

What does a sustainable, inclusive, and productive seed system look like?

For the future, there are serious challenges for expanding and deepening the impact from investments in breeding. Market intelligence systems are urgently needed to support breeding teams in future product design and evidence-based prioritization. Innovation is needed in terms of how actors within the systems inform and support farmers to experiment with new seeds.

CIMMYT is working with CGIAR partners to implement a new, 10-year strategy. Effective seed systems achieve the widespread adoption of varieties that capture the gains from crop improvement and connect actors along the value chain so that all can benefit from a productive crop, from seedbank to soil. In close collaboration with national agricultural research systems (NARS), CGIAR has had historic success introducing improved cultivars to smallholder producers of staple crops, with high return on investment. However, there is still some standing criticism that large, public breeding programs take a technologically-biased and supply-pushed approach to agricultural innovation.

Cereal crop breeding programs can become more demand-oriented by employing more market segmentation strategies – breaking down target client markets into smaller, more geographically and demographically specific groups – and developing a more accessible description and profile of its products. Using similar approaches, CGIAR is likely to expand demand-oriented programs in genetic innovation and seed systems development in the new phase of operations.

Novel technology to reduce the complexity of maize seed production and increase maize hybrid yields in farmer’s fields

A recently published study in Nature Communications Biology journal demonstrates the potential of a novel seed production technology to transform Africa’s seed production system, conferring important benefits to smallholder maize farmers and seed companies in sub-Saharan Africa.

The Seed Production Technology for Africa (SPTA) process enables production of non-pollen-producing inbred seed that can be used in a two-step multiplication process to produce commercial seed of hybrid varieties containing equal parts pollen producing and non-pollen producing plants.  The pollen producing plants provide pollen for the entire field, while the non-pollen producing plants deliver additional grain since they save energy by not producing pollen. Hybrids in which fifty percent of the plants are non-pollen producing have a significant grain yield advantage compared with hybrids in which all plants produce pollen.

Farmers and researchers evaluated the performance of fifty percent non-pollen producing (FNP) hybrids  in side-by-side comparisons across diverse farm sites in Kenya, South Africa, and Zimbabwe between 2016 and 2019. The results demonstrate that FNP hybrids deliver an average yield increase of 200 kg per hectare, representing a 10-20% increase at current sub-Saharan Africa yield levels where farmers face frequent drought and sub-optimal soil fertility. The FNP yield advantage was consistent in both low yielding and higher yielding conditions.  Additionally, in extensive farmer surveys, farmers rated the FNP hybrids higher than the pollen producing counterparts, recognizing the grain yield advantage. Favorable rating of FNP hybrids suggests that farmers are likely to adopt them once available.

Although consistent and steady improvement is being made for grain yield potential through plant breeding, the yield benefit of FNP hybrids is the equivalent of approximately six years of breeding progress under stressful conditions.  The FNP trait provided a consistent yield advantage in several genetically unique hybrids evaluated, indicating that the yield advantage from FNP will be complementary to and additive with progress from maize breeding efforts.

In sub-Saharan Africa, the challenge of delivering genetically pure, high-quality seed is substantial. Seed companies in the region contend with a complex and costly system to produce commercial seed. In addition to delivering higher grain yield to farmers through the FNP trait, the SPTA process will reduce the complexity of seed production, enabling seed producers to deliver higher purity improved hybrid seeds in sufficient quantities for smallholder farmers.

Hybrid seed production requires that one of the parents of the hybrid is prevented from producing pollen, ensuring that the seed harvested has been cross-fertilized by the pollen parent. Most hybrid seed production in sub-Saharan Africa involves physical removal of the tassels of the seed parent prior to the release of pollen, a process known as detasseling. Detasseling is important in commercial seed production to prevent self-fertilization of the seed parent plants. Nearly all detasseling in sub-Saharan Africa is done by hand, which is a labor-intensive and time-sensitive process. Poorly executed or ill-timed detasseling results in unwanted self-fertilization of the seed parent, leading to rejection of seed and incurring losses to the seed producer. Furthermore, timely detasseling typically involves removal of one or more leaves together with the tassel, reducing the photosynthetic capacity of the plant, and lowering the seed yield.

Use of the SPTA process ensures that the seed parent of the hybrid will not produce pollen, thereby eliminating the need for detasseling. This means seed producers can ensure higher integrity of hybrid seed while reducing costs and increasing seed yield. The technology is well suited for the three-way hybrid production commonly used in sub-Saharan Africa. Economic advantages to seed companies of using seed from the SPTA process is also expected to provide incentive to replace older, lower yielding varieties with more recently developed hybrids. Providing improved quality seed of better hybrids while delivering the yield advantage of the FNP trait can benefit smallholder maize farmers throughout the region. Saving costs can help the seed sector remain strong and competitive, which leads to increasingly better options for farmers in the future.

The G20 Foreign Ministers’ meeting held on July 7-8 in Bali saw Chinese State Councillor and Foreign Minister, Wang Yi, highlight support for CGIAR as part of a proposed cooperation initiative to boost global food security.

Foreign Minister Wang Yi highlighted the need to help CGIAR increase innovation and build cooperation on agricultural science and technology among countries. Addressing the meeting, Wang said the food and energy sectors are crucial for the healthy performance of the world economy and the effective implementation of the UN 2030 Agenda for Sustainable Development. 

His statement was made shortly before the signing of Letters of Intent for Cooperation between the Chinese Academy of Agricultural Sciences (CAAS) and two CGIAR Research Centers, the International Maize and Wheat Improvement Center (CIMMYT) and the International Rice Research Institute (IRRI).  

CIMMYT, IRRI and CAAS intend to establish a joint Center in Hainan to address global food security through advances in wheat and rice breeding. The collaboration aims to enhance the environmental sustainability of rice and wheat based agri-food systems, promote biodiversity conservation, combat climate change, and improve the health and welfare of growers and consumers. 

Jean Balié, Regional Director, South East Asia and Pacific, CGIAR, and Director General of IRRI said: “Our new agreement solidifies and updates a longstanding and fruitful partnership. Today we face a different and growing set of challenges to our food, land and water systems, and we welcome the opportunity to strengthen knowledge and information exchange from across CGIAR that will contribute to a transformation of global food, land and water systems.” 

CIMMYT Director General, Bram Govaerts added: “This state-of-the-art breeding center will help us develop and deploy the new nutritious, high-yielding and resilient varieties that Asian farmers need to feed and nurture the most populous region of the world sustainably or within planetary boundaries.” 

In three decades of collaboration, CAAS and CGIAR have cooperated on germplasm exchange, breeding new varieties of crops, and providing opportunities for staff collaboration, development and training. 

In wheat research, the partnership has added as much as 10.7 million tons of grain – worth $3.4 billion – to China’s national wheat output. Additionally, eight CIMMYTscientists have won the Chinese Friendship Award – the highest award for foreign experts who have made outstanding contributions to China’s economic and social progress. 

A reaffirmation of Chinese support for CGIAR comes on a tide of growing recognition that more investment is needed to tackle hunger.  

Earlier in the year the G7 Foreign Ministers’ Communiqué underlined the urgent need to address risk in global food systems citing this as a top foreign policy objective. At the same time, the G7 Agricultural Ministers Communiqué cautioned that slowing down work to address longer term goals of food systems transformation, in order to address short term food crises, will have negative consequences in the medium and long term. In this context CGIAR’s System Board Chair, Marco Ferroni, recently highlighted the need for world leaders to look at the big picture to solve the food crisis.

China to build international agricultural breeding center in Hainan

The Chinese Academy of Agricultural Sciences (CAAS), the International Maize and Wheat Improvement Center (CIMMYT) and the International Rice Research Institute (IRRI) are establishing a breeding center in Sanya, Hainan Province, China.

The international cooperation will be conducive to the exploration and utilization of germplasm resources of the research organizations, biological breeding research, technical training, and the innovation of the global seed industry.

Cereal seed value chains in Nepal

Cereals cover around 80% of Nepal’s cultivated land area, with a low level of productivity. The country’s commercial cereal seed sector development has been rather slow as more than 83% of seed comes from the informal system. The formal sector cannot produce adequate seeds to meet the farmers’ needs. Moreover, the formal market is largely driven by public seed varieties. To catalyze the sector’s development and enhance productivity, building a well-performing seed system that produces and timely supplies quality seeds at affordable rates to farmers is integral.

The adoption of a federal system of governance since 2018, creating new structures within the system, along with the after-effects of COVID-19 has impacted the public sector seed production and distribution with implications on private seed business. A recent assessment conducted by the International Maize and Wheat Improvement Center (CIMMYT) examines the current functions in the cereal value chain in Nepal and identifies upgrading strategies to bring efficiency and competitiveness in the cereal seed market systems, specifically for rice and maize.

The study provides a detailed analysis of the market size and trends for the various hybrid and open-pollinated varieties of rice and maize seeds as well as their production, distribution and margins in seed business.

A majority of rice and maize seeds, especially high-yielding hybrids, sold to farmers are brought in by importers and wholesalers who directly sells them to farmers or indirectly through agro-dealers. Nepali hybrid varieties are lagging because farmers, grain producers and millers have low awareness and information on new and improved varieties produced by local seed companies and cooperatives. A significant supply gap of rice and maize seeds was found in all the seven provinces of Nepal.

The study reviews the nature of inter-business relations in the seed value chain and provision of services by the government, NGOs and others for the development of the cereal seed value chain. In the context of federalism, the study assesses the seed policies and actions under the Revised Seed Act (2020) to establish provincial seed systems. Considering migration-induced feminization of agriculture in Nepal, the study identifies approaches to promote inclusive seed systems and youth engagement in seed value chains. Strategic measures to build a resilient seed system that can respond to abrupt market and mobility disruptions, as caused by the COVID-19 pandemic, is also taken into account. However, it also details out the various challenges and risks encountered by the value chain actors that hinders seed business and the sector’s growth overall.

Some of the strategies to address these bottlenecks include strengthening value chain functions in research and development, hybrid seed production, seed processing and innovative approaches for market promotion and sales. Creating an enabling environment for seed companies in areas of variety testing and release, quality assurance in seed production and commercialization, financial and business management services, seed extension services and promotion of new domestic varieties are also fundamental propositions to achieve Nepal’s National Seed Vision (2013-2025) targets.

Hands-on experience in seed production

Recently, a group of 40 postgraduate students from Nepal’s Agriculture and Forestry University (AFU) were able to learn first-hand about hybrid maize seed production in a field site managed by a partner seed company of the International Maize and Wheat Improvement Center (CIMMYT). Bringing in a whole new and rare experience altogether, the students got a glimpse of the progress and challenges of the seed industry as of today.

The field trip followed the development of a revised curriculum for AFU’s Seed Science and Technology program, initiated in November 2019, which stresses the importance of creating linkages between university students and private seed companies. Through the USAID-supported Nepal Seed and Fertilizer (NSAF) project, CIMMYT is working towards enhancing partnerships between agricultural universities and the seed industry, and revisiting the curriculum has been the first stepping stone.

In collaboration with AFU and Lumbini Seed Company, CIMMYT organized an off-campus participatory learning experience to enrich students’ understanding of hybrid seed production initiatives by the private sector and the opportunities that lie in the various business models of Nepalese seed companies. The initiative is part of a concerted effort by CIMMYT and its partners to alleviate the critical limitations of skilled manpower in the industry.

A deep dive into hybrid seed

The program began with an on-site briefing on the recent developments of hybrid seed production by the private sector.

“Nowadays, farmers are increasingly demanding hybrid seeds over open-pollinated varieties due to their higher yields,” explained Subash Raj Upadhyaya, Managing Director of Lumbini Seed Company. This seed demand is almost entirely met via imports.

Since 2018, the company has been successful in producing and marketing hybrid maize seed such as Rampur Hybrid-10, a variety originally sourced from CIMMYT and released in Nepal by the National Maize Research Program with technical and financial support from the NSAF project. Going from one hectare to 25 hectares of hybrid maize seed production in the course of three years, Lumbini Seed Company has demonstrated the capability of local private seed companies building up the country’s capacity in this area.

“The collaboration between public and private seed stakeholders is helping Nepal to realize hybrid seed self-reliance in the foreseeable future,” explained AbduRahman Beshir, seed systems lead for the NSAF project at CIMMYT. “What is needed is competitive products augmented by quality seed production and effective marketing strategies.”

Beshir described the important stages of seed production and the components of robust seed systems, while Hari Kumar Shrestha, a seed systems officer at CIMMYT, detailed the requirements for quality seed production and certification of hybrid seeds as per government guidelines in Nepal. Participating students were then able to practice detasseling and roughing off-type plants from a single row in a hybrid maize production field, under the guidance and supervision of the team from CIMMYT and the seed company.

This was followed by an interactive discussion with representatives from Lumbini about their activities, developments and limitations, and a tour of the company’s seed processing, laboratory and storage for the group to observe the techniques used to produce, maintain and market quality seeds.

A nourishing experience

Applying the theoretical learnings of plant breeding and agronomy courses in a practical setting was an eye-opener for the postgraduates.

Student Sadhana Poudyal shared how the event had boosted her confidence in performing critical activities such as identifying the key features of pollen and seed parents. Now majoring in Seed Science and Technology, Poudyal previously worked with the Nepal Agriculture Research Council (NARC) and was granted a scholarship by CIMMYT, through the NSAF project, to begin a postgraduate program in 2019. “I was fascinated to learn about the remarkable progress made in hybrid seed production and I feel motivated to work in this sector in the future,” she said. Poudyal plans to use these learnings during her research into baby corn at NARC after completing her studies.

“I have always been keen on learning plant genetics and breeding as I foresee a good scope in this area,” said Lokendra Singh, another student at AFU. “This trip was definitely insightful, and I thoroughly enjoyed receiving a practical lesson on the advantages and limitations of the various types of hybrids including single and three-way cross hybrids. Today’s experience has doubled my enthusiasm to work as a plant breeder after my graduation.”

It is critical to engage students on the recent advances in seed science so that they are encouraged to pursue a career in agricultural research in Nepal. “One of the major challenges is recruiting a workforce with critical skills and knowledge in the local seed industry since many students go abroad after they graduate,” said Upadhyaya. “We look forward to partnering with agricultural universities for many similar on-site learnings.”

Educational experiences in the field, such as this, provide a better picture of the recent advancements and limitations in the seed sector which are usually not reflected in the textbooks. Creating a larger pool of skillful human resources, particularly in hybrid product development, improved seed production technologies and quality seed production, will not only help strengthen the local seed industry but also reduce the country’s dependency on imports in the coming years.

Fighting the stress

East African Seed Company has a rich history of nearly 50 years, serving farmers with improved climate-resilient seed varieties. Established in 1972, the company produces and sells improved seed, through a wide distribution network in at least 15 countries in sub-Saharan Africa. It also markets agrochemicals and other farm inputs, and has ambitions of expanding to the rest of Africa, trading as Agriscope Africa Limited.

Smallholder farmers in sub-Saharan Africa continue to face multiple biotic and abiotic stresses as they try to improve their farms’ productivity and their livelihoods. Maize seed that guarantees high yield is a key trait, coupled with other key attributes such as drought tolerance, disease and pest resistance, early seedling vigor as well as suitability for food and animal feed.

With the varieties serving both small- and large-scale commercial farmers, challenges such as the fall armyworm, diminishing soil fertility and erratic rains have persisted in recent years and remain as key farming obstacles. “Such challenges diminish crop production and the grain quality thereby, lessening farmers’ profitability,” says Rogers Mugambi, Chief Operating Officer of East African Seed Company.

Scientists at the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with partners in the national agriculture research systems and the commercial seed sector, continue to develop seed varieties that can guarantee decent yield even in times of climatic, disease and pest stress.

Top-notch research trickles down to farmers

Over the years, East African Seed has inked partnerships with CIMMYT, national research institutes and other agencies in the countries where it operates. Such partnerships have been the driving force to its success and the impacts within the farming communities in sub-Saharan Africa.

“Our collaboration with CIMMYT began in 2008 with germplasm acquisition. The cooperation has expanded to include testing networks for new hybrids, early-generation seed production and marketing. The overall beneficiary is the smallholder farmer who can access quality seeds and produce more with climate-smart products,” Mugambi says.

Apart from the multi-stress-tolerant varieties developed and released over time by the national agricultural research programs, CIMMYT recently announced a breakthrough: fall armyworm-tolerant elite maize hybrids for eastern and southern Africa. This success followed three years of rigorous research and experiments conducted in Kenya and signified a key milestone in the fight against fall armyworm.

As part of the partnership in the Drought Tolerant Maize for Africa (DTMA) and Stress Tolerant Maize for Africa (STMA) projects, East African Seed Company (Agriscope Africa Limited) established demonstration farms and conducted field days in Kenya, reaching thousands of farmers as a result. It was also able to produce early generation seed, which supported production of 2,000 metric tons of certified seed. This partnership now continues in the Accelerating Genetic Gains in Maize and Wheat (AGG) project.

The company has contracted large- and small-scale growers across the country to meet its seed production targets.

“Most of our small-scale growers are clustered in groups of up to 30 farmers with less than five acres of farmland. The large growers have advanced irrigation facilities such as the pivot system and seed processing plants. The seed from the fields is pre-cleaned and dried in the out-grower facilities before delivery to our factory for further cleaning and processing,” Mugambi explains.

Out with the drought

Currently, of the 1,300 metric tons of drought-tolerant hybrid seeds it produces yearly, 500 metric tons constitute those derived from the partnership in the STMA project. Two notable hybrids,  HODARI (MH501) and TOSHEKA (MH401), were derived during the DTMA and STMA projects. Released in 2014 and accepted for regional certification through the Common Market for Eastern and Southern Africa (COMESA)’s regional catalogue, the MH501 is a mid-altitude adapted and medium maturing three-way cross hybrid. The yield advantage of 15% over the local commercial checks triggered widespread adoption by the farmers, according to Mugambi. In Kenya, it was used as a commercial check during national performance trials, from 2017 to 2019.

The MH401, an early maturing hybrid with moderate drought tolerance, has been adopted in lowland and mid-altitude dry ecologies of Kenya and Tanzania. It has a 20% yield advantage over the local commercial checks.

As part of its varietal replacement, East African Seed Company looks to steadily retire older varieties such as KH600-15A and WE1101 and promote new ones including TAJIRI (EASH1220), TAJI (MH502) and FARAJA (MH503).

To promote new varieties and successfully reach smallholders, the company conducts field days, farm-level varietal demonstrations, road shows and radio programs. It also disseminates information on the benefits of new varieties while also dispensing promotional materials such as branded t-shirts and caps.

“Additionally, we organize annual field days at our research farm in Thika, where key and influential farmers and other stakeholders are invited from across Kenya and neighboring countries to learn about our new agricultural technologies,” Mugambi says.
