Enhancing maize seed and feed security

Maize is the second most important cereal in Laos after rice, driven primarily by the demand for animal feed in neighboring countries such as China, Thailand, and Vietnam. Laos has an export-oriented maize sector, with most of the country’s production destined for these markets. The sector reached its peak in 2016, when production levels hit 6 metric tons per hectare across an area of 0.26 million hectares.

Over 90% of Laos’s maize production relies on rain-fed agriculture, with maize grain and stover serving as the primary source of feed for smallholder farmers who depend on mixed crop and livestock farming systems for their livelihoods. However, between 2016 and 2022, total maize area and production declined significantly, contracting by 64% and 70%, respectively. Several factors contributed to this decline, including volatile market prices, competition from cassava and other crops, rising production costs, and yield losses due to pests, diseases, and soil nutrient degradation because of monocropping.

Additionally, Laos relies on imported hybrid maize seed, primarily from Thailand and Vietnam, which creates a dependence on external suppliers and exposes farmers to price fluctuations. Recognizing the importance of improving maize productivity and sustainability, the Laotian government is taking steps to enhance local capacity for seed production and ensure access to affordable high-quality feed.

Enhancing local hybrid maize seed production  

Recognizing the importance of enhancing the availability and accessibility of quality maize seed and feed, CIMMYT and Laos’s National Agriculture and Forestry Research Institute (NAFRI) have initiated the evaluation of high-yielding maize hybrids for both grain and stover quality. In 2023, 12 yellow-kernel maize hybrids developed by the CIMMYT-Asia breeding program underwent evaluation in Laos. The same set of hybrids is undergoing evaluation in 2024 to identify stable and suitable germplasm. According to Siviengkhek Phommalath, director of the rice and cash crop research center at NAFRI, the 2023 evaluation provided promising results, with at least two hybrids performing better or on par with widely grown commercial ones in Laos. These hybrids exhibit high productivity, particularly in terms of grain and stover quality. However, further validation is planned for 2024, with the introduction of additional testing sites to assess performance across various environments.

Following thorough evaluations across multiple years and environments, the most suitable dual-purpose maize hybrids will be allocated to NAFRI by CIMMYT along with their parental lines, to kickstart local seed production. However, the capacity of national partners needs to be strengthened to initiate local hybrid maize seed production effectively, and this necessitates the integration and coordination of efforts among all stakeholders in the seed and feed value chains in Laos.

Capacity building across seed and feed value chains

In response to the need for capacity building in local hybrid seed production and ensuring a consistent supply of high-quality seed and feed to Laotian smallholder farmers, NAFRI has collaborated with CIMMYT under the CGIAR Sustainable Intensification of Mixed Farming Systems (SIMFS), Seed Equal, and Plant Health Initiatives to organize an international training workshop on enhancing access to quality maize seed and feed in the crop-livestock farming system of Lao PDR, which took place from May 7-9, 2024.

The three-day interactive workshop, held in Vientiane, brought together 28 specialists from various organizations, including NAFRI, Souphanou Vong University, the Upland Agriculture Research Center (UARC), Provincial Agriculture and Forestry Offices (PAFO), as well as maize seed importers and grain traders from different provinces within the country.

The first day was dedicated to understanding the challenges and opportunities of the maize seed value chain. Participants were divided into three groups based on their practical backgrounds and invited to discuss challenges, stakeholder roles, and develop actionable recommendations for better coordination across value chains. This multi-stakeholder platform aimed to comprehend the challenges and opportunities of the crop-livestock farming nexus and integrate them into a more sustainable and productive system. It also served as a forum to promote synergistic partnerships among value-chain actors in enhancing local access to good quality seed and feed. The following days focused on various essential components of quality hybrid seed production, including understanding product profiles and market segments, realizing the economics of hybrid maize seed production, seed quality assurance, management of maize pests and diseases, and enhancing maize stover quality.

A collaborative approach

Workshop participants highlighted the challenges they face in acquiring maize seeds from external sources, citing inconsistent delivery times and limited availability of preferred varieties as factors that posed significant operational constraints. “The development of a competitive domestic maize seed system would ensure timely seed supply for farmers and save resources for the nation,” said Maisong Yodnuanchan, an agripreneur from Xiangkhouang province. His concerns resonated with fellow agripreneurs Bounmy Si and Teuang Sophapmixay, from Oudomxay and Hua Phan provinces, respectively, who both acknowledged the challenges associated with the current reliance on imported seeds and the potential benefits of a sustainable, locally produced seed supply.

The training workshop offered valuable insights into addressing these concerns, providing a comprehensive overview of effective seed system development and the technical aspects of seed production applicable to a wide range of crops beyond maize. “This is the first ever training I received in my career and the knowledge gained will be directly applicable to my research activities at the UARC,” said researcher Malay Soukkhy. Recognizing the unique context of Laos compared to most of its neighboring countries with more established seed systems, AbduRahman Beshir, CIMMYT’s seed systems specialist for Asia and the lead trainer and facilitator for the workshop, emphasized the need for a collaborative approach to develop a custom solution for Laos. The workshop itself exemplified this collaborative spirit, incorporating a variety of engaging formats such as group discussions, lectures, assignments, and participant presentations. Subject matter specialists from CIMMYT offices in Nepal, India, and Kenya, as well as experts from Alliance Bioversity-CIAT and ILRI offices in Asia, shared valuable experiences applicable to Laos’s seed and feed systems.

Cementing partnerships

While addressing the participants, Timothy J. Krupnik, regional director for CIMMYT’s Sustainable Agrifood Systems Program in Asia, opened the workshop by acknowledging the invaluable support of NAFRI for organizing the event and collaborating under the CGIAR mixed farming initiative. He highlighted the imminent finalization of a Memorandum of Understanding (MoU) between CIMMYT and NAFRI, which will pave the way to further cement partnerships and establish a long term CIMMYT operations in Laos.

NAFRI’s Director General, Chanthakhone Bualaphan, presided over the workshop and emphasized the importance of continued collaboration between CIMMYT and NAFRI. Bualaphan requested CIMMYT’s continued focus on capacity building in Laos, encompassing both human resource development and institutional strengthening. She further highlighted the establishment of a specific target for domestic hybrid maize seed production, aligning with the government’s self-sufficiency goals.  To translate plans into action, Bualaphan emphasized the need for future training programs to be more action-oriented and practical. She concluded by reiterating NAFRI’s unwavering support for CIMMYT’s expanded activities in Laos, with the ultimate objective of significantly improving the livelihoods of Laotian farmers. The workshop culminated with the presentation of certificates to participants and the development of a collaborative follow-up plan for deploying well-tailored maize germplasm within the mixed farming system of Laos.

From April 3-4, 2024, CIMMYT hosted the International Conference on Strengthening Maize Value Chains in Nepal, organized in collaboration with the Ministry of Agriculture and Livestock Development, the Department of Agriculture (DOA), the National Agriculture Research Council (NARC), and the Agri Enterprise Center (AEC) of the Federation of Nepali Chamber of Commerce and Industry (FNCCI), with support from the United States Agency for International Development (USAID).

“Maize holds the potential to yield manifold benefits for farmers, the private sector, and the Government of Nepal, through the development of an efficient market system,” said Judith Almodovar, acting director of the Economic Growth Office at USAID Nepal. With this in mind, the two-day conference held in Kathmandu brought together government officials, policymakers, industry leaders, and experts from Nepal and the wider region to explore avenues for advancing the country’s maize sub-sector. It served as a platform for participants from India, Bangladesh, and Nepal, representing various functions of the maize value chain to share and exchange innovative commercial maize production, post-harvest, supply chain, and marketing models and policies aimed at improving efficiency, ensuring sustainability, and fostering competitiveness.

Addressing the opening session, Honorable Minister of Agriculture, Jwala Kumari Sah, highlighted the Government of Nepal’s priority to increase maize production and marketing, emphasizing the need to provide maize for food, feed, and fodder to boost incomes and improve livelihoods. While highlighting objectives and expectations from the conference, Country Representative for CIMMYT in Nepal, Dyutiman Choudhary, shared information about CIMMYT’s mandate and global expertise in maize science, as well as interventions to develop a maize seed-to-feed model in Nepal. The organization’s model fosters public-private farmer partnerships for commercial maize production as a key approach to develop an inclusive and sustainable maize sub-sector in the country. “As a result, maize yields have doubled in Nepal and farmer gate prices have increased by 50% in the last two years,” Choudhary explained.

Recommendations for sustainable improvement

The conference involved five different technical sessions over the course of two days, each focused on various themes related to production, marketing, international best practices, and policies. Experts from Bangladesh, India, and Nepal were involved in insightful discussions and shared valuable knowledge and experience for advancing the commercialization of the maize sub-sector in Nepal.

Participants made recommendations for the sustainable improvement of national maize production and commercialization to meet the growing demand for food, feed, and fodder while reducing reliance on imports. These include developing high-yielding, short-duration, stress-tolerant maize varieties, and identifying models for commercial maize production, post-harvest, storage, market linkages, and supportive policies for improved investment and coordination among public sectors, market actors, and service providers to meet national maize demand.

At the closing session, Govinda Prasad Sharma, secretary at the Ministry of Agriculture and Livestock Development (MOALD), notified attendees that MOALD is in the process of strengthening a national strategy for maize commercialization and that the learning from the conference will provide valuable inputs. He added that the participation of experts from neighboring countries has provided deep insights for policy development.

A tale of two worlds: contrasting realities in southern and northern Zambia during El Niño

From the densely lush landscape of Zambia’s northern province to the arid terrain of the south, a stark reality unfolds, intensified by El Niño. Zambia’s agriculture faces contrasting realities yet potential lies in adaptive strategies, a diversified crop basket, and collaborative initiatives which prioritize farmers. Despite persistent challenges with climate variability and uneven resource distribution, the country navigates unpredictable weather patterns, emphasizing the intricate interplay between environmental factors and adaptation strategies.

Unpacking El Niño’s impact in Zambia

El Niño presents a common challenge to both southern and northern Zambia, albeit with varying degrees of intensity and duration. The 2022/2023 season had above normal rainfall amounts, with extreme weather events, from episodes of flash floods and flooding to prolonged dry spells, especially over areas in the south. In the 2023/2024 season, the southern region has already experienced irregular weather patterns, including prolonged droughts and extreme temperatures, leading to water scarcity, crop failures, and significant agricultural losses. Although the growing season is nearing its end, the region has only received less than one-third of the annual average rainfall (just about 250 mm). Dry spells of more than 30 days have been experienced and, in most cases, coincide with the critical growth stages of flowering and grain-filling. A glance at farmers’ fields paints a gloomy picture of the anticipated yield, but all hope is not lost.

In contrast, the northern province stands out receiving above-average rainfalls beyond 2,000 mm, providing a different set of challenges for crop production. In this region, incidences of waterlogging are prominent although the effects are not as detrimental as the drought in the southern province. In general, crops in the northern province promise a considerable harvest as compared to the ones in the southern province.

Maize stover and its competing use

The scarcity of resources in southern Zambia extends beyond water availability, with the competition for maize stover, a valuable byproduct used for animal feed which can also be retained on the soil surface for fertility improvement and soil moisture conservation. With limited access to alternative fodder sources, farmers face challenges in meeting the nutritional needs of their livestock while maintaining soil fertility and conserving moisture. The struggle to balance the competing demands for maize stover underscores the complex dynamics of resource management in the region. This is further worsened by the low maize stover yield expected due to the dry conditions.

Implementing fodder trials, which include cultivating fodder crops like mucuna and lablab, intercropped or rotated with maize, offers a lifeline to farmers. While maize crops may wilt under the stress of El Niño-induced droughts, leguminous crops such as mucuna, lablab, cowpea, and groundnuts exhibit resilience, thriving in adverse conditions and providing a crucial source of food, feed, soil cover, and income for farmers. The ability of legumes to withstand environmental stressors highlights the importance of crop diversification in building resilience to climate change and ensuring food security in vulnerable regions.

Conversely, in northern Zambia, the abundance of agricultural resources allows for a more sustainable utilization of maize stover. Farmers have greater access to fodder alternatives and can implement integrated farming practices to optimize the use of crop residues. This enables them to mitigate the adverse effects of soil degradation and enhance livestock productivity, contributing to the resilience of their agricultural systems.

Use of more climate-smart crops

In southern Zambia, maize stands as the main crop, often supplemented with the integration of some leguminous crops integrated to some extent, to diversify the agricultural landscape. However, the relentless and longevity grip of El Niño has taken a negative toll on maize production, despite efforts to cultivate drought-tolerant varieties. As the dry spell persists, maize plants at the critical tasseling and silking stage face an uphill battle, as the dry and hot air has adversely impacted pollen and silk development.

The dissimilarity with the northern province, where cassava thrives from abundant water, is striking. This resilient crop, known for its drought tolerance, presents a promising alternative for farmers in the southern province grappling with erratic rainfall patterns. As climate change continues to challenge traditional agricultural practices, exploring resilient crops like cassava may offer a lifeline for communities striving to adapt and thrive amidst adversity.

In response to these radically different realities, the Sustainable Intensification of Farming Systems (SIFAZ) project, a collaborative effort of CIMMYT with FAO, the Ministry of Agriculture in Zambia, and the CGIAR Initiative on Diversification in East and Southern Africa, also known as Ukama Ustawi, have jointly promoted sustainable intensification practices to enhance the resilience of smallholder farmers.

The SIFAZ project is designed around the idea that strip crops and intercrops can add nutritional and economic value to Conservation Agriculture (CA) systems for smallholder farmers in Zambia. While traditional yield metrics provide some insight across the several intercropping treatments being tested on-farm, the true benefits of these cropping systems extend beyond mere output. SIFAZ recognizes the diversification synergy, emphasizing that “two crops are better than one.”

However, the outcomes of the SIFAZ project and the CGIAR Initiative on Diversification in East and Southern Africa have varied over the years between the two regions, reflecting the discrepancy in their agricultural landscapes.

Notably, regional differences in the adoption and success of these cropping systems have become apparent. In the northern province, crop-centric approaches prevail, leading to a higher concentration of successful crop farmers. Meanwhile, in the southern province, mixed systems that incorporate mixed crop-livestock systems achieve desirable effects. These findings highlight the importance of tailoring agricultural interventions to suit the specific needs and conditions of diverse farming communities.

Navigating the complex challenges of climate change requires a multifaceted approach that acknowledges the unique realities of different regions. By embracing adaptive strategies, harnessing indigenous knowledge, and fostering collaborative partnerships, Zambia can forge a path towards a more resilient and sustainable agricultural future, where farmers thrive despite the uncertainties of a changing climate.

Seeds of change: one woman’s mission to transform her community

In the heart of Itumbula village in the Songwe district of Tanzania lives Venansia Swale, a farmer, mother, and community champion, who is turning the tide against food insecurity through the power of quality seeds. Swale has taken on the role of promoting improved seed in her community after experiencing firsthand the benefits of growing sorghum on her own farm with different seed.

“As a mother of five children, my biggest challenge is food shortage, and sorghum is our staple food,” said Swale. “Normally, I would harvest 450 kg from my three-acre farm, which isn’t enough for my family’s needs and leaves little surplus for selling. However, using quality seed this season, I harvested 990 kg. I’ve seen the benefits–not only can I feed my children for a year, but I can also earn income from the surplus.”

Swale’s efforts began to extend beyond her own farm as she championed demand creation and consolidation in her village of Itumbula. She successfully created a demand of 574 kg, becoming her community’s sole distributor of quality sorghum seed. In the 2022-2023 season, she facilitated the supply of 134 kg of quality sorghum seed and 50 kg of quality maize seed.

So far, she has reached 300 farmers in partnership with CIMMYT and the Tanzania Agricultural Research Institute (TARI), sparking a transformative movement. One local farmer said, “As a community, we have come together to embrace quality seed, and Venansia has been at the forefront of this movement. Her dedication has significantly impacted food security.”

Despite being pregnant during the 2022 “Kizazi cha Mabadiliko” (the generation that will bring change) campaign, Swale remained unwavering in her determination and passion. She exemplifies the success of the Social and Behaviour Change interventions implemented by the Centre for Behaviour Change and Communication (CBCC).

The “Kizazi Cha Mabadiliko” campaign was developed and launched by CBCC in the Mbozi and Momba districts of Tanzania, aiming to increase awareness of the benefits of improved seeds. It was also designed to challenge negative perceptions and enhance motivation for participating in agricultural activities. The campaign underscores the importance of using improved seeds as a foundational element for a prosperous future in agriculture. The strategic design of the campaign ensures the efficient distribution of behavior change tools and materials, further demonstrating its impact through Swale’s inspiring example.

Sprouting new opportunities

Despite her impressive achievements, Swale remains forward-thinking. The village extension officer notes that while farmers have adopted improved seeds, poor farming practices persist, impacting yields. Inspired and invigorated, Swale plans to revolutionize her farming practices in the upcoming season, aiming for an even more significant impact.

Besides her role as a community champion, Swale is a member of the Sifa choir in her church. Leveraging her influence, she convinced nine fellow choir members to join the intervention, where they established and managed sorghum demonstration plots in their locality. The performance of quality seed inspired the choir to enlist as seed producers, and they secured two acres of land for seed production in the 2023- 2024 season.

Venansia’s vision goes beyond her own farm; she plans to produce seeds as part of the choir group and individually, allocating an acre for seed production and two acres for grain production. Hers is a story of personal triumph, showing the impact one person can have on an entire village, and a testament to the transformative power of community-led initiatives.

“The seeds we plant today will grow into a better tomorrow for all of us,” asserts Swale.

Product Design Teams (PDTs): A client-oriented approach to defining market segments and target product profiles

Product design teams (PDTs) are a CGIAR Accelerated Breeding Initiative innovation created to address the aforementioned challenges under the CGIAR-NARES partnership through coordinating SPMS and related TPPs. Each seed product market segment, which in the case of CGIAR is defined at sub-regional level, represents a unique set of requirements. Attached to the segment is a TPP which describes the ideal product to meet the requirements. Taken together, the framework provides a starting point for discussions by breeding teams on investment opportunities.

Discussions on market segments and TPPs need to develop over time as new insights are gained. Some requirements might be overlooked, and others may be emerging due to client requirements and changes in the context. There is a need for a greater understanding of the evolving requirements of the seed companies, farmers, processors, and consumers in the market segments that CGIAR serves. It must be recognized that not all requirements of farmers or consumers are amenable to breeding or efficient to incorporate in breeding pipelines – for example, some post-harvest losses or weed management can be best addressed by appropriate storage mechanisms and improved agronomic practices, respectively.

Product design teams (PDTs) were created to address the aforementioned challenges under the CGIAR-NARES partnership by and coordinating SPMS and related TPPs. A PDT is a group of crop breeding and seed systems stakeholders for a particular crop, who work together to design or redefine TPPs. PDTs have been envisioned to be cross-functional teams that meet annually with the following aims:

  • Review the market segments at subregional and national levels, addressing critical questions, such as:
    • Do the subregional segments capture country-level requirements?
    • What is the opportunity for impact from breeding investments across market segments?
    • Are there important market segments that have not been captured?
    • What are the potential future segments that the team needs to consider?
  • Review and update TPPs for each segment, addressing questions such as:
    • Are any important traits missing?
    • Are country-specific trait values factored?
    • Are country-specific market-dominant varieties included in the market segment?
  • Discuss the needs for market intelligence for the PDT:
    • Unknowns regarding client requirements.
    • Gaps regarding product design parameters.

Director of the Global Maize program at CIMMYT, B.M. Prasanna, said, “PDT meetings serve as an important platform to understand the perspectives of diverse and relevant stakeholders. These discussions enable us to reach a common understanding of the current market requirements and redefine TPPs to reflect needs across value streams through co-creation and shared responsibility.”

The impact of PDTs

Pieter Rutsaert, seed systems specialist at CIMMYT and the CGIAR Market Intelligence Initiative, participated in several PDTs on maize and other crops, such as groundnut. “PDTs are a useful format to understand the unknowns in terms of farmer, processor, and consumer requirements and generate questions that guide future work in market intelligence,” said Rutsaert.

“PDTs will help in routine review of the product requirement for a specific country and will help to remove breeder bias and ensure that all stakeholders’ views are heard and considered”, said Aparna Das, technical program manager for the Global Maize program at CIMMYT.

The main requirements for constituting PDTs for a specific country are:

  • A multidisciplinary team with 7 to 15 members, ensuring diversity of experience and providing reasonable time for decision-making.
  • Must consist of a range of stakeholders, such as: breeders from NARES (often the PDT convener/lead) and CGIAR; representatives of farmers’ groups, seed companies, and food processors; gender specialists; and market intelligence specialists.
  • 30% of members should be female.
  • Should include a member from another crop breeding network, to bring a different perspective.

Bish Das, NARS coordinator, Dragan Milic, breeding specialist, and Lennin Musundire, breeding optimization specialist, from the CGIAR Accelerated Breeding Initiative team said, “Ultimately, the client-led approach to priority setting that CIMMYT’s Global Maize program is implementing in southern and eastern Africa ensures strong alignment with partners’ priorities and client requirements and better targeting of CGIAR regional maize breeding efforts.”

Case study: maize seed systems

CIMMYT’s Global Maize program has refined variety development to meet market needs across the value chain including farmers, processors, and consumers, thus enhancing variety adoption, which is the end goal of breeding pipelines. This has been implemented through the regional CGIAR-NARES-SMEs collaborative breeding networks and having ‘a bottom-up’ approach towards developing market segments and TPPs. This refers to building an understanding of end-users’ needs through inclusive in-country and regional stakeholder PDT meetings. PDTs also ensure that there are CGIAR-NARES-SME defined roles: a national mandate for NARES partners focusing on niche markets, the consolidated national mandate for CGIAR/NARES/SMEs, and a regional mandate for CGIAR Research Centers like CIMMYT.

In 2023, maize PDT teams were established and held meetings for five countries in eastern and southern Africa: Zambia, Ethiopia, Kenya, Zimbabwe, and Uganda. These meetings brought together stakeholders from different fields who play an important role in product development and seed systems (national partners and seed companies), varietal release (representatives from regulatory agencies) and end-product users (for example, millers).

The advantages of TDPs are emphasized by Godfrey Asea, director of Research and Daniel Bomet Kwemoi, maize breeder at the National Agricultural Research Organization (NARO) in Uganda. They highlighted that the NARO maize program has now begun a systematic journey toward modernizing its breeding program. The PDT team validated the country’s market segments and aligned five product profiles with two major target production environments (TPEs), with the mid-altitude regions taking 85% of the maize seed market and the highlands accounting for 15%. “These TPPs will be reviewed annually by the PDT since market segments tend to be dynamic. The breeding program has reclassified and aligned breeding the germplasm to TPPs, which will guide effective resource allocation based on the market shares,” said Asea.

Feedback on PDT meetings so far suggests positive experiences from stakeholders. Wendy Madzura, head of agronomy at SeedCo in Zimbabwe, said, “The unique PDT meeting held at CIMMYT in Zimbabwe provided a conducive environment for public and private stakeholders to have meaningful and honest discussions on the current market segments and TPPs.” Plans for continuous improvement are embedded in the PDT model. “As a follow-up to the PDT meeting, there is a need for further involvement of various stakeholders at the village, ward, and district levels to enable deeper insights and reach because the client needs are constantly changing,” said Madzura.

Tackling fall armyworm with sustainable control practices

Typically looking like a small caterpillar growing up to 5 cms in length, the fall armyworm (FAW, Spodoptera frugiperda) is usually green or brown in color with an inverted “Y” marking on the head and a series of black dots along the backs. Thriving in warm and humid conditions, it feeds on a wide range of crops including maize, posing a significant challenge to food security, if left unmanaged. The fall armyworm is an invasive crop pest that continues to wreak havoc in most farming communities across Africa.

The first FAW attack in Zimbabwe was recorded around 2016. With a high preference for maize, yield losses for Zimbabwe smallholder farmers are estimated at US$32 million. It has triggered widespread concern among farmers and the global food system as it destroyed large tracts of land with maize crops, which is a key staple and source of farmer livelihood in southern Africa. The speed and extent of the infestation caught farmers and authorities unprepared, leading to significant crop losses and food insecurity.

Exploring the destructive FAW life cycle

It undergoes complete metamorphosis, progressing through four main stages including egg, larva, pupa, and adult. Reproducing rapidly in temperatures ranging from 20 to 38°C, moist soil conditions facilitate the egg-laying process, while mild winters enable its survival in some regions. The larval stage is the most destructive phase, feeding voraciously on plant leaves and can cause severe defoliation. They can migrate in large numbers, devouring entire fields within a short period if left unchecked.

Working towards effective FAW management

Efficient monitoring, early detection, and appropriate management strategies are crucial for mitigating the impact of FAW infestations and protecting agricultural crops. To combat the menace of this destructive pest, CIMMYT, with support from the United States Agency for International Development (USAID), has been implementing research and extension on cultural control practices in Zimbabwe. One such initiative is the “Evaluating Agro-ecological Management Options for Fall Armyworm in Zimbabwe”. Since 2018, this project strives to address research gaps on FAW management and cultural control within sustainable agriculture systems. The focus of the research has been to explore climate-adapted push-pull systems and low-cost control options for smallholder farmers in Zimbabwe who are unable to access and use expensive chemical products.

Environment friendly practices are proving effective to combat FAW risks

To reduce the devastating effects of FAW, the project in Zimbabwe is exploring the integration of legumes into maize-based strip cropping systems as a first line of defense in the Manicaland and Mashonaland east provinces. By planting maize with different, leguminous crops such as cowpea, lablab and mucuna, farmers can disrupt the pests’ feeding patterns and reduce its population. Legumes release volatile compounds that repel FAW, reducing the risk of infestation. Strip cropping also enhances biodiversity, improves soil health and contributes to sustainable agricultural practices. Overall results show that FAW can be effectively managed in such systems and implemented by smallholder farmers. Research results also discovered that natural enemies such as ants are attracted by the legumes further contributing to the biological control of FAW.

Recently, the use of biopesticides such as Fawligen has gained traction as an alternative to fight against fall armyworm. Fawligen is a biocontrol agent that specifically targets the FAW larvae. Its application requires delicate attention – from proper storage to precise mixing and accurate application. Following recommended guidelines is essential to maximize its effectiveness and minimize potential risks to human health and the environment.

Impact in numbers

Since the inception of the project, close to 9,000 farmers participated in trainings and exposure activities and more than 4,007 farmers have adopted the practices on their own field with 1,453 hectares under improved management. Working along with extension officers from the Ministry of Lands, Agriculture, Water, Fisheries & Rural Resettlement, the project has established 15 farmer field schools as hubs of knowledge sharing, promoting several farming interventions including conservation agriculture practices (mulching, minimum tillage through ripping), timely planting, use of improved varieties, maintaining optimum plant population, and use of recommended fertilizers among others.

Addressing FAW requires a multi-faceted approach. The FAW project in Zimbabwe is proactive in tackling infestation by integrating intercropping trials with legumes, harnessing the application of biopesticides, and collaborative research. By adopting sustainable agricultural practices, sharing valuable knowledge, and providing farmers with effective tools and techniques, it is possible to mitigate the impact of FAW and protect agrifood systems.

Combatting maize lethal necrosis in Zimbabwe

Maize is a staple crop in Zimbabwe, playing a vital role in the country’s agricultural landscape as food for its own people and an export good. However, behind every successful maize harvest lies the quality of seed and resistance to diseases and stresses.

Amidst the multitude of diseases that threaten maize crops, one adversary is maize lethal necrosis (MLN). Though not native to Zimbabwe, it is crucial to remain prepared for its potential impact on food security.

What is maize lethal necrosis?

MLN is a viral disease, caused by a combination of two virus diseases. The disease emerged in Kenya in 2011 and quickly spread to other countries in eastern Africa. The introduction of MLN to Africa was likely affected by the movement of infected seed and insect vectors. MLN has had a severe impact on regional maize production, leading to yield losses of up to 90%.

Recognizing the need to equip seasoned practitioners with the knowledge and skills to effectively diagnose and manage MLN, CIMMYT organized a comprehensive training on MLN diagnosis and management, targeting 25 representatives from Zimbabwe’s Plant Quarantine Services.

From students to experienced technicians, pathologists and plant health inspectors, this was an opportunity to refresh their knowledge base or an introduction to the important work of MLN mitigation. “This training for both advanced level practitioners and students is crucial not only for building competence on MLN but also to refresh minds to keep abreast and be prepared with approaches to tackle the disease once it is identified in the country,” said Nhamo Mudada, head of Plant Quarantine Services.

Expectations were diverse, ranging from sharpening understanding of key signs and symptoms to learning from country case examples currently ridden with the disease. With CIMMYT’s guidance, practitioners learned how to identify MLN infected plants, make accurate diagnoses, and implement management strategies to minimize losses.

“For over 10 years, these trainings have been important to raise awareness, keep local based practitioners up to speed, help them diagnose MLN, and make sure that they practice proper steps to tackle this disease,” said L.M Suresh, CIMMYT maize pathologist and head of the MLN screening facility in Kenya.

Identifying the specific MLN causing viral disease affecting a maize plant is the first step in combating MLN. Determining whether it is a biotic or abiotic disease is critical in establishing its cause and subsequent diagnosis. By implementing proper diagnostic techniques and understanding the fundamentals of good diagnosis, practitioners can bring representative samples to the lab and accurately identify MLN.

Tackling MLN in Zimbabwe

Initiated in 2015 at Mazowe as a joint initiative between the Government of Zimbabwe and CIMMYT, a modern quarantine facility was built to safely import maize breeding materials from eastern Africa to southern Africa and enable local institutions to proactively breed for resistance against MLN.

The MLN quarantine facility at the Plant Quarantine Institute is run by the Department of Research and Specialist Services (DRSS) and is mandated to screen maize varieties imported under strict quarantine conditions to ensure that they are MLN-free.

To date, CIMMYT and partners have released 22 MLN resistant and tolerant hybrids in eastern Africa. CIMMYT’s research and efforts to combat MLN have focused on a multidimensional approach, including breeding for resistant varieties, promoting integrated pest management strategies, strengthening seed systems, and enhancing the capacity of farmers and stakeholders.

“Support extended through valuable partnerships between CIMMYT, and the collaborations have played a pivotal role from surveillance to diagnostics and building capacity,” said Mudada.

Feedback and insights

Chief Plant Health Inspector for Export and Imports Biosecurity, Monica Mabika, expressed gratitude for the training. “It is always an honor when we have expert pathologists come through and provide a valuable refresher experience, strengthening our understanding on issues around biosecurity and learning what other countries are doing to articulate MLN,” she said.

Among the students was Audrey Dohwera from the University of Zimbabwe, who acknowledged the importance of the training. “I have been attached for 2 months under the pathology department, and I was eager to learn about MLN, how to detect signs and symptoms on maize, how to address it and be able to share with fellow farmers in my rural community,” she said.

With the knowledge gained from this training, practitioners are well equipped to face the challenges that MLN may present, ultimately safeguarding the country’s maize production status.

Strengthening seed systems with Zamseed

Maize is a vital crop in Zambia and Tanzania, both for farmers’ economic livelihoods and for delivering nutrients and sustenance to a large group of people. But maize is threatened by climate change, like more severe droughts, and from pests like fall army worm (FAW), which can completely devastate farmers’ fields.

Against this backdrop of looming threats, CIMMYT, as part of the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, or MasAgro Africa, is partnering with the Zambia Seed Company Limited (Zamseed) to distribute seeds that are drought tolerant and resistant to the ravages of FAW. And because maize is a staple of many people’s diets, CIMMYT and Zamseed are also developing and distributing maize varieties enhanced with vitamin A.

To uphold maize variety integrity, CIMMYT and Zamseed are engaged in the capacity building of quality assurance and quality control for local stakeholders.

CIMMYT’s engagement with Zamseed involves efforts to popularize high yielding, drought-tolerant, and vitamin enhanced maize varieties in Zambia and Tanzania. Some of these efforts include demonstrations of the new varieties, field days held at different stages of maize development, and deliberate engagement of women throughout the entire seed selection, planting and harvesting effort.

“Our partnership with Zamseed started in October 2022,” said Ir Essegbemon Akpo, a CIMMYT maize seed systems specialist. “It has been a fruitful collaboration, delivering significant outputs to thousands of farmers in Zambia and Tanzania.”

To date, Zamseed has held 300 and 500 demonstrations in Tanzania and Zambia, respectively. The company has held many field days at the demonstration sites to showcase drought tolerant and vitamin A enhanced maize to hundreds of small-scale farmers.

“We have witnessed many farmers who visited the demonstration activities who are excited to see the new high yielding and drought tolerant varieties,” said Amsal Tarekegne of Zamseed.

Seeded by funds from the AID-I project, Zamseed is producing 60kg of Early Generation Seed (EGS) of parents of a FAW-tolerant hybrid maize variety. The company plans to produce 200kg of this hybrid for commercialization and launch in 2024.

To ensure that seeds delivered to farmers are of the highest quality, CIMMYT is working with Zamseed to develop quality assurance and control frameworks, involving genotyping of selected seeds at various times during the seed multiplication and distribution process.

Zamseed has been servicing the requirements of farmers in the sub-Sahara region since 1980, focusing on products that will enhance the profitability of the small-scale farmer and ensure household food security.

Strengthening seed systems emphasized to enhance Bhutan’s seed and food security initiatives

Quality seed is a crucial agricultural input for enhancing crop production and productivity per unit of land. However, in many developing countries, including Bhutan, ensuring the availability, affordability, and accessibility of quality seed, especially of preferred varieties, remains a significant challenge for farmers. Maize is the second most important cereal in Bhutan after rice. However, the total area dedicated to cereal cultivation in Bhutan has been decreasing due to factors such as rural-urban migration, urban expansion, and the effects of climate change.

Between 2016 and 2021, the areas under rice and maize cultivation have contracted by 55% and 64%, respectively (FAOSTAT, 2022). This huge reduction in cereal cultivation, combined with relatively low productivity, has led Bhutan to rely on imports to bridge the gap and meet the demand for essential food crops, including maize. The Bhutanese government is committed to enhancing domestic capacity and fostering self-sufficiency in major food crops and discourages the import of seed, especially of hybrid maize.

Hybrid maize seed to offset deficit

Recognizing the significance of improving maize productivity, the Agriculture Research & Development Center (ARDC) in Bhutan is working on the development and deployment of hybrid maize that has the potential to double yields compared to non-hybrid varieties. In 2020, Bhutan officially released its first hybrid maize variety, Wengkhar Hybrid Maize-1 (WHM-1), which was sourced from CIMMYT. Furthermore, several other hybrid maize varieties from CIMMYT are currently in the pipeline for release and evaluation, including those tolerant to fall armyworm (Spodoptera frugiperda), the most important maize pest in Bhutan.

Despite the testing and release of hybrid maize varieties, the production of high-quality seed—vital for realizing the benefits of hybrid maize for Bhutanese farmers—has yet to take place. The seed industry in Bhutan is primarily informal, with the majority of farmers relying on farm-saved seed of often inferior quality. The absence of a formalized seed system, coupled with a lack of the necessary skills and technical expertise across the seed value chain, presents considerable challenges in building a competitive and vibrant seed sector in Bhutan.

Training workshop emphasizes the strengthening of seed systems

To ensure a consistent supply of high-quality maize seed to Bhutanese farmers, which is essential for seed and food security and improved productivity, ARDC in collaboration with CIMMYT, under the CGIAR Seed Equal Initiative, carried out an international training workshop on quality seed production and distribution, with the main focus on hybrid maize, from 13–15 November 2023 at ARDC-Wengkhar, Mongar.

The three-day workshop involved 30 participants from diverse organizations, including the National Seed Centre, the College of Natural Resources, extensions agents from the eastern region, the Bhutan Food and Drug Authority, and agriculture research and development centers. The workshop aimed to enhance participants’ technical skills in understanding and applying the principles and practices of quality hybrid maize seed production; to promote synergistic partnerships among various seed sector stakeholders for initiating and scaling up quality hybrid maize seed production in Bhutan; and to exchange experiences and lessons to be learned from South Asian countries that can be applied to strengthening Bhutan’s seed system.

“This is the first kind of training I have received on hybrid maize seed production, and it was very relevant, action-oriented and applicable to our condition in Bhutan,” says Kinley Sithup, a researcher at ARDC-Wengkhar, Mongar, and adds that the training workshop was a useful forum for identifying key challenges and the role of stakeholders across the seed value chain, which were discussed in detail during the group work in the training.

Recently, the Bhutanese government has restricted the import of hybrid maize seed in order to promote import substitution and enhance local seed production. “In light of the unavailability of imported hybrid seeds, it’s crucial for us to intensify our efforts in scaling up local seed production,” says Dorji Wangchuk, project director of the Commercial Agriculture and Resilient Livelihood Enhancement Program (CARLEP), while addressing the participants during the opening.

The training workshop covered courses on seed system components, maize breeding concepts, hybrid seed production principles, the development of a seed roadmap on production and marketing, hybrid seed pricing and marketing approaches, seed quality control and certification, among others. A field visit along with hands-on training at ARDSC Lingmethang enriched the learning experience. In addition, experiences from other South Asian countries on hybrid seed production and marketing were shared during the training.

Team up for seed production

A significant outcome is the planned initiation of the inaugural hybrid maize seed production group in Udzorong, Trashigang, scheduled for January 2024 in collaboration with extension, the National Seed Center, and the Bhutan Food and Drug Authority. This initiative, supported by CARLEP-IFAD and CIMMYT, reflects a dedicated effort to strengthen Bhutan’s seed sector and enhance maize production for the benefit of local farmers. Fast-track variety release and seed deployment are important to Bhutanese smallholder farmers to mitigate the challenges of lower productivity. “CIMMYT is ready to continue working with partners in Bhutan,” says Program Director of the Global Maize Program at CIMMYT and the One CGIAR Plant Health Initiative lead, BM Prasanna, while delivering his messages online. Prasanna added that CIMMYT has licensed three fall armyworm-tolerant hybrids for Bhutan, and partners need to team up for the release and seed-scaling of the hybrids.

The training workshop on hybrid maize seed was the first of its kind to be held in Bhutan and was conducted under the CGIAR Seed Equal Initiative in collaboration with ARDC and CARLEP. AbduRahman Beshir, seed systems specialist at CIMMYT, delivered the main courses, with additional virtual presentations from CIMMYT staff from India and Kenya.

Early maturity products popular among farmers in Kenya

Across all production environments in Kenya, early-maturity products demonstrate strong sales. This was revealed in a recent study by the CGIAR Initiative on Market Intelligence. During the long-rains season, farmers in higher rainfall production environments—wet, mid and high altitudes—purchased early-maturity seed products despite potentially lower yields. Also, the short-rains season, which represents almost one-fourth of total maize seed sales, was dominated by early-maturity products.

These insights were obtained through a panel of maize-seed sales data from 722 agrodealers in Kenya during two short-rains seasons and three long-rains seasons in 2020–2022. The study also offers insights into the extent the maturity level of seed products, purchased by farmers in Kenya, aligns with the production environment where they were sold. Market Intelligence applies eight criteria to identify seed product market segments (SPMSs) for CGIAR crop breeding. In the application of these criteria to maize in East Africa, two conditions distinguish the segments: production environment and maturity level. The other criteria do not vary. A key indicator for prioritizing breeding investments across segments is the relative size of SPMSs. In the case of maize, and other crops, teams generally use geospatial data to identify the area of production environments, with the assumption that farmers in each production environment would use the seed product with the maturity level designed for that environment.

The paper contends that a stronger focus on using sales data to inform breeding decisions in maize, and potentially other crops where retailers play an important role in seed distribution, should become a priority for market intelligence. Future work will engage stakeholders in maize seed systems in other countries of East Africa about the changes in demand for earlier-maturing products and the implications for segmentation.

LIPS-Zimbabwe empowers farmers through innovative intercropping trials

Since 2021, CIMMYT, in partnership with the International Livestock Research Institute (ILRI), the French Agricultural Research Centre for International Development (CIRAD), and the University of Zimbabwe’s Department of Veterinary, has been working in rural communities of Zimbabwe, as part of the Livestock Production Systems in Zimbabwe (LIPS-Zim) project. The activity is led by Zimbabwe’s Department of Research and Specialist Services and is at the forefront of introducing new agricultural innovations to local farmers.

One of their most impactful initiatives has been the intercropping trials involving maize and various legumes including jack bean, mucuna, lablab, and pigeon pea. This groundbreaking approach has not only transformed the lives of farmers but has also had a positive impact on the overall health of livestock.

Various leguminous fodder crops have been promoted widely as sources of high-quality protein feed in mixed crop-livestock systems of Zimbabwe. However, to diversify and increase the options for the drier regions, the LIPS-Zim project is testing new leguminous crops such as jack bean and pigeon pea, which are well-adapted to dry conditions.

Netsai Musekiwa, a farmer in the town of Mutoko, has been part of the LIPS-Zim project for the past two seasons, and is currently conducting intercrop trials with jack bean. “Since I started intercropping maize with jack bean, I have been amazed by the results and will continue on this path. The jack bean plants have shown strong tolerance to prolonged dry spells and heat stress,” she said. “Next season, I plan to extend my plot to harvest more jack bean.” These words of encouragement on intercropping maize with jack bean have also been largely echoed by many other farmers in Mutoko and Buhera during the feedback meetings held in October 2023.

What is intercropping and how beneficial is it to farmers?

Intercropping is an agricultural practice of growing two or more crops together on the same field simultaneously to maximize land use and enhance productivity. As different crops have different growth patterns and nutrient requirements, intercropping can help optimize resource utilization and boost overall crop output.

In addition, intercropping reduces the risk of climate induced crop failure as well as minimizing pest damage, enhances soil fertility by diversifying the root system, and can provide additional income streams to farmers.

The science behind jack bean and pigeon pea

Jack bean (canavalia ensiformis) and pigeon pea (cajanus cajan) are leguminous crops valued for their nitrogen-fixing abilities which aides in improving soil fertility. Both jack bean and pigeon pea have deep root systems, making them ideal candidates for the dry semi-arid conditions in Zimbabwe.

Pigeon pea is known for its drought-tolerance and produces edible seeds used in various culinary dishes and is a source of both food and feed. Jack bean is used as a forage crop for livestock, providing nutritious feed.

“Jack bean seeds contain a toxic compound called canavanine, which can be harmful when consumed in large quantities or not properly processed. To make jack beans safe for consumption, it must be boiled, soaked, or fermented,” said Isaiah Nyagumbo, cropping systems agronomist at CIMMYT. “We have introduced many farmers to the best practices for handling jack beans and have opened up new possibilities for its utilization in sustainable farming practices.”

While some farmers were intercropping with jack bean, others explored pigeon pea as an alternative. “I liked the intercropping of maize and pigeon pea on my plot. I am assured of getting nutritious food both for my family and livestock. After harvesting, I usually take the branches, then put them in the shade and dry them to retain the nutritional value. I occasionally give some to my goats during the dry season when feed from natural pastures is scarce, and my goat herd has risen to 12 goats,” said Fungai Kativu, a farmer in Mutoko.

Building capacity of local farmers

To narrow the knowledge gap and highlight the potential of such feed options, LIPS-Zim has also been spearheading the establishment of community level learning centers. These centers are a knowledge hub to local farmers, providing practical knowledge, facilitating the sharing of different perspectives while nurturing working as groups with a common vision. This “farmer learns by seeing” approach has been a success in the community.

Through this initiative, farmers have not only witnessed increased productivity but have also gained the necessary skills and knowledge to adapt to the changing agricultural landscape. “Intercropping leguminous crops with maize has shown great potential in improving food security and livestock feed production in Zimbabwe’s farming communities, especially in areas prone to heat and drought,” said Nyagumbo.
