Preventing nitrogen loss in maize

Written by Julian Bañuelos-Uribe on . Posted in Publications.

The widespread availability of chemical nitrogen fertilizers is a prime driver of the vast improvement of crop yields over the past 50 years. However, their use has come with a price, as nitrogen escaping into surrounding soil and air has negative impacts on the environment and human health, including water pollution, depletion of soil-fertility, and greenhouse gas emissions.

Researchers from CIMMYT and JIRCAS (Japan International Research Center for Agricultural Science) examined ways to curtail the leakage of nitrogen into ecosystems, through a process called biological nitrification inhibition (BNI) in the paper “Genetic variation among elite inbred lines suggests potential to breed for BNI-capacity in maize,” published in the journal Scientific Reports on August 17, 2023.

BNI is a plant-based natural process that reduces nitrogen losses, which can reduce fertilizer demand while sustaining agricultural systems. The roots of plants that exhibit BNI activity release natural substances that inhibit the activity of nitrifying bacteria in soil, thus reducing the amount of nitrogen lost to the surrounding ecosystem. Many plant species have natural BNI activity in their roots.

Although synthetic chemical nitrification inhibitors are commercially available to reduce nitrogen losses, the high costs of this approach have limited its adoption. By contrast, breeding new varieties with increased natural BNI activity can offer a practical and economical approach to reduce nitrogen fertilizer need and waste.

“We are in the discovery phase regarding BNI activity and its determining traits for maize. Such information is crucial to pave the way for breeding programs and genetic improvement efforts,” said Kevin Pixley, co-author of the paper and former director of CIMMYT’s Genetic Resources Program. “We need to identify genetic markers for BNI compounds including ‘zeanone’, which will enable breeders to develop maize varieties that require and waste less nitrogen fertilizer, while achieving high yields.”

This research identified 18 single nucleotide polymorphisms (SNP) that act as genetic “signposts” for breeders to use to accelerate and increase the accuracy of breeding to increase BNI activity for maize. The researchers also identified six “candidate” or putative genes associated with BNI activity and related to nitrogen use efficiency, thereby enhancing the understanding of the genetics controlling BNI activity.

“Our identification of SNPs and genes that regulate how maize processes nitrogen begins to draw a road map to guide the development of molecular markers for use in breeding new maize varieties that meet farmer and consumer needs at a lower environmental cost,” said senior author Cesar Petroli. “Building on the results obtained and reported in our recent publication, we are developing maize (doubled haploid) populations to refine the genetic map for BNI activity in maize”.

This research was conducted with partners from JIRCAS and the Universidad de la RepĂșblica, Uruguay.

Harnessing new high-resolution satellite imagery to plant breeding

Written by Julian Bañuelos-Uribe on . Posted in Publications.

In plant breeding, efforts to increase the rate of genetic gains and enhance crop resilience to the effects of climate change are often limited by the inaccessibility and costs of phenotyping methods. The recent rapid development of sensors, image-processing technology and data analysis has provided new opportunities for multiple scales phenotyping methods and systems. Among these, satellite imagery may represent one of the best ways to remotely monitor trials and nurseries planted in multiple locations, while standardizing protocols and reducing costs.

This is because relevant data collected as part of crop phenotyping can be generated from satellite images. For instance, the sensors onboard the SkySat satellite constellation of Planet Labs have four spectral bands—blue, green, red, and infrared—which can be used to calculate the normalized difference vegetation index (NDVI), which is a measure of vegetation and its greenness, and various canopy traits like ground cover, leaf area index and chlorosis. It can also be used to monitor plot establishment and phenological parameters.

The use of satellite-based phenotyping in breeding trials has typically been restricted by low resolution, high cost and long intervals between fly-overs. However, the advent of a new generation of high-resolution satellites—such as the SkySat constellation—now offers multispectral images at a 0.5m resolution with close to daily acquisition attempts on any place on Earth. This could be a game changer in terms of the scale at which yield trials can be conducted, enabling more precise variety placement and thereby increasing genetic diversity across farmer’s fields and reducing the probability of disease epidemics. It could also revolutionize the capacity for research in realistic field conditions, since traits can be measured throughout the cycle in a highly standardized way, over multiple sites at low cost. For example, an image which covers 25 km2 can monitor an entire research station at a cost of about US$300.

To test the suitability of this technology, a team of researchers from CIMMYT set out to evaluate the reliability of SkySat NDVI estimates for maize and wheat breeding plots of different sizes and spacing, as well as testing its capacity for detecting seasonal changes and genotypic differences.

Both their initial findings, recently published in Frontiers in Plant Science, and more recently acquired data, show that the SkySat satellites can be used to monitor plots commonly used in wheat and maize nurseries. While wheat yield plots usually are 1.2m wide, maize plots tend to consist of at least two rows, resulting in a width of 1.5m. Plot length ranges from 2-4m. The authors also discuss on other factors to be considered when extracting and interpreting satellite data from yield trials, such as plot spacing.

Through the successful collection of six satellite images in Central Mexico during the rainy season and parallel monitoring of a maize trial in Zimbabwe, the researchers demonstrate the flexibility of this tool. Beyond the improvement of spatial resolution, the researchers suggest that the next challenge will be the development and fine-tuning of operational procedures that ensure high quality, standardized data, allowing them to harness the benefits of the modern breeding triangle, which calls for the integration of phenomics, enviromics and genomics, to accelerate breeding gains.

Hard work pays off

Written by Julian Bañuelos-Uribe on . Posted in Features.

Nepal is an agricultural country, where the sector provides the major source of income for half the population. Despite this, the sad reality is that the country is not able to produce enough crops to meet its needs, and major grains like rice, maize, and cereals are mostly imported.

One factor influencing this is an aging population of farmers, alongside decreasing interest in agriculture among the country’s youth. Many young people do not see agriculture as a viable option for employment, opting instead for work opportunities outside the country. However, there are still some youth who see agriculture as a profitable business, like Pradeep Morya.

“It is better to work hard in your home country rather than going abroad and working tirelessly every minute and hour,” says Morya, a 24-year-old farmer from Banke, Nepal, who finds happiness in living close to his family and helping to support national food security. “I love being in the field,” he explains. “I have cultivated spring maize on one hectare. My day-to-day business is to provide care to the spring maize along with pumpkins and beans that I have added for additional income on a small plot of land.”

Working alongside his eldest brother, Morya has cultivated 30 kattha of land (equivalent to 0.36 hectares) using the spring maize varieties Pioneer 1899 and DK 9108. His brother, a member of Mahatarkari cooperative in Duduwa, western Nepal, has been providing him with the knowledge and expertise needed for maize cultivation.

Mahatarkari is one among 50 cooperatives working in partnership with the Nepal Seed and Fertilizer project (NSAF), which is implemented by CIMMYT. NSAF works with the cooperatives to provide technical knowledge and training to farmers, to hone their potential and support them in the adoption of modern technologies which can improve their livelihoods. After participating in programs organized by NSAF, Morya makes sure that the suggestions he receives — on soil preparation, weed management, harvesting, and more — are implemented in his field.

Returning to the family farm

A few years back, the situation was different. Like many youths in the country, Morya also went abroad to try his luck on the international job market. He worked hard for two years in Malaysia but was forced to return to Nepal during the COVID-19 pandemic.

“I had imagined my shining future abroad. However, when I reached there, the reality was different,” recalls Morya. “I returned to my own country just before the lockdown in April 2021 with some small savings. Upon my arrival in Nepal, I was clueless about my future. I dropped my education after grade five. With no educational qualifications and skills in hand, it was difficult to get a decent job.”

Since the country was in lockdown, Morya chose to stay at home and support his family on the farm. It was here that his eldest brother guided him into farming, and Morya soon learned the knowledge needed to run the farm and began earning money from it. This attracted him towards farming as a longer-term career option, and he has now discovered a prosperous future in agriculture.

“Agriculture needs continuous effort,” he says. “With the support of technology, it is easy and efficient to work. I work every day so that I can reap crops on a large scale to make a profit. I manage weeds, irrigation, and control pests.”

“I also have livestock. I get adequate fodder for my cows and buffalo from weeds and from the spring maize. I sell milk in the market. In addition to this, I also make sure to produce off-season vegetables so that I receive a decent price for additional income.” With the support of his family, Morya has recently purchased an e-rickshaw, which he uses to transport and sell his produce.

To further support his endeavors, Morya has also been participating in Nepal’s Maize Commercialization Network and using the Geo Krishi mobile app to learn about current market prices. “Before knowing about the commercialization of crops, it was hard to receive good amounts from buyers,” he explains. “Now, I make a call to the local retailers and buyers to learn the best value of my grain. Sometimes I also explore the market. Then, I analyze the rate and sell my maize.” He uses a similar system for his off-season vegetables, selling either in the local market or directly to consumers for a premium price. “I make a saving of around 1500 Nepalese rupees (approximately US$ 11) per day,” he says.

A prosperous life

With the profits from his agricultural business, Morya has been able to fulfill his dream of purchasing a bike, as well as contributing to the construction of a new eight-room house, where his family is now living comfortably. “I love to roam on my bike with my friends in the evening. I also take my mother for a ride,” says Morya with a bright smile. “Now, I have a dream to live a prosperous life with my family.”

Thanks to the support provided by the NSAF project with generous funding from USAID, young people like Morya can pursue a better life for themselves and their families. Agricultural training programs have not only helped young people fulfill their basic needs, but also to achieve their dreams. It is hoped that ongoing efforts to empower farmers through science and innovation will continue helping young farmers like Morya break the chain of unemployment, for both their own benefit and that of Nepal.

CIMMYT announces 2030 Strategy

Written by Julian Bañuelos-Uribe on . Posted in Features.

The world’s food systems are under threat by escalating armed conflicts, economic stagnation, the effects of the climate crisis and natural resource degradation. Against this backdrop, the next seven years are crucial in meeting the challenges of keeping the world’s growing population fed and secure.

Recognizing that business as usual will not be sufficient, CIMMYT has embarked on a journey to proactively face the new challenges of the 21st century. This novel approach to agrifood systems is the core of CIMMYT’s 2030 Strategy, which has the potential to shape the future of agriculture.

“We understand that the challenges facing food security are complex, varied and rapidly changing. For instance, the effects of COVID-19 and Ukraine-Russia conflict on food systems are still being felt today. With that in mind, we set out to develop a strategy that is both robust and nimble. The best way to create a sustainable and inclusive strategy was to engage directly with CIMMYT scientists and staff, the people on the front lines of this effort to deliver food and nutrition security to the world,” said CIMMYT Director General Bram Govaerts.

Looking back to move forward

The first step in crafting the 2030 Strategy was looking at where does CIMMYT want the world to be in 2100. In answering this question, CIMMYT crafted a long-term vision of how it wants to engage in a changing world and achieve the transformation to a food and nutrition secure world within planetary boundaries. CIMMYT has integrated the use of foresight and specifically a set of 2030 Food and Agriculture scenarios to explore potential changes in intervention areas over the strategic period and help prepare engagements in different contexts across the globe. These scenarios are a decision-making tool that has underpinned the development of the strategy to ensure that it is context-driven and focused on the most pressing challenges facing the agrifood systems in which CIMMYT operates.

From the future CIMMYT looks back at its history and examines how its core business has evolved over the years to proactively meet ever-changing needs across the world.

At each stage of CIMMYT’s evolution, it has taken its strengths and the skills it has built and added to its experience, and expanded on what it delivers while maintaining the core strengths.

In CIMMYT’s earliest days, the mission was developing and improving germplasm and agronomic practices, then CIMMYT began working more closely with farmers (1980s), broadened emphasis in genetic improvements (2000), embarked on sustainable multidisciplinary projects (2010s), and most recently, advancing technologies in participatory innovation systems (2015-2022). All leading to the mission codified in the 2030 Strategy: accelerating food systems transformation by using the power of collective action.

Now, in 2023, CIMMYT’s progress is being shaped by the CGIAR mission statement: “To deliver science and innovation that advance the transformation of food, land, and water systems in a climate crisis.”

Building the Strategy

To define the 2030 Strategy, CIMMYT responded to the following core questions:

  • What does success look like?
  • Where can CIMMYT deliver the most value?
  • How can CIMMYT deliver value for communities?

“As an organization, we have concentrated on strategies that foster collaboration and adapt them for a non-profit international organization whose vision is not to grow as an institution but to deliver greater value for the communities they serve, to innovate for the end users of their products and to ensure a better future for our global community,” said Govaerts.

The tools used to develop the elements of this strategic plan leveraged the framework provided in the CGIAR Research and Innovation Strategy to guide the process. Staff from across the Center engaged in a consultative process to develop the objectives for following strategic components: Excellence in Science and Innovation, Excellence in Operations, Talent Management, Resource Mobilization, Partnership, and Influence.

Developing the Excellence in Science and Innovation component serves as an example of this collaborative, bottom-up approach. Planning was led by the Emerging Thought Leaders Group, made up of 24 early and mid-career scientists across the breadth of CIMMYT’s global and program portfolio. The group worked collaboratively with CIMMYT researchers and staff to first delineate the challenges facing agri-food systems and then workshopped solutions which now serve as the foundation of the 2030 Strategy.

“Each component complements the others,” said Govaerts. “This is our answer to the core questions. Only by working collectively can we initiate sustainable solutions that reach everyone.”

Together, the components create a network to support CIMMYT’s three pillars: Discovery (research and innovation), SystemDev (working collaboratively to innovate foundational systems), and Inc. (incubating startups and new ways of doing business in the agri-food system space).

CIMMYT is leading the way in shaping a sustainable and prosperous agricultural landscape

The goal to facilitate food security where sustainable agriculture is part of the solution to the climate crisis and agriculture provides an avenue to build household resilience and enables communities to pull themselves out of poverty requires the strategic use of resources. CIMMYT’s 2030 Strategy, built from the bottom up on a foundation over 50 years’ experience and the expertise of scientists, staff, and farmers maximizes resources, enhances dynamic partnerships, and both retains and recruits a world-class staff in a world of growing challenges to food security.

CIMMYT Director General reaffirms commitment to Zambia

Written by Julian Bañuelos-Uribe on . Posted in News.

Honoring a legacy of innovative development in Zambia and looking forward to meeting the nation’s goals for food security, Bram Govaerts, director general of the International Maize and Wheat Improvement Center (CIMMYT), along with CGIAR Board Chair Lindiwe Sibanda, visited facilities and met with southern Africa collaborators of the Southern Africa AID-I Rapid Delivery Hub on June 2 and 3, 2023.

“CIMMYT’s work in Zambia and the region is geared to help national governments build resilience to climate change, diversify maize-based farming systems and improve productivity and production to address reduce hunger and poverty,” said Govaerts.
Southern Africa AID-I Rapid Delivery Hub aims to provide critical support to over 3 million farming households in Malawi, Tanzania and Zambia via targeted interventions for demand driven seed scaling, improved soil health and fertilizer use efficiency, and rapid delivery of critical agricultural advisory services deep into rural communities.

CIMMYT research and innovation supports Zambia’s medium-term goal of “Socio-Economic Transformation for Improved Livelihoods” and its 2030 Vision of becoming “A Prosperous Middle-Income Nation by 2030.”

Govaerts and Sibanda toured Afriseed’s factory in Lusaka and its wheat field trials in Ngwerere. They also attended a field demonstration of Purdue Improved Crop Storage bags in the nearby district of Chongwe organized by the Catholic Relief Services, a local partner promoting low-cost post-harvest technologies for small-scale farmers in Zambia.
The delegation visited private partner Zamseed, a company commercializing and releasing CIMMYT-bred, Fall Armyworm tolerant maize seeds.

Southern Africa AID-I Rapid Delivery Hub has enabled the release of nearly 10,000 metric tons of certified maize and legume seed, which have been harvested by Zambian seed companies and community-based seed organizations, directly benefiting a million semi-subsistence farmers.

Govaerts also hailed Zambia’s commitment to creating a transparent seed system. “Thanks to this conducive policy environment, Zambia is a major hub in sub-Saharan Africa for hybrid maize seed production and export in Africa.”

Besides Southern Africa AID-I Rapid Delivery Hub, CIMMYT and the Zambia Agricultural Research Institute have been collaborating for over two decades along with public and private partners in Zambia through different investments designed to create sustainable interventions that strengthen food systems and directly reach small-scale farmers.

A seed systems success story

Written by Tawanda Hove on . Posted in Features.

Stewards Global, trading as Afriseed, is a Zambia seed systems intervention success story. Thanks to support from the International Maize and Wheat Improvement Center (CIMMYT) and other partners such as the United States Agency for International Development (USAID) and the Alliance for a Green Revolution in Africa (AGRA), Afriseed is transforming rural farmers’ livelihoods through supplying drought tolerant maize seed.

What began as a start-up in 2007 has since grown to be one of the leading companies in Zambia’s seed industry. “I started this company with a team of three people. We did not have much, but we had a compelling vision,” says founder Stephanie Angomwile. “Initially, we were multiplying and distributing legume seed to the market as we had observed the deficit where it was very difficult for any serious farmer to procure improved and high-performing seed.”

“Having set up the business, we were fortunate to get AGRA’s support to secure proper industrial premises where we could focus our operations and serve the Zambian market,” she explains. “Using a basic drum seed dresser, we were able to churn out 100 metric tons of seed per season, which was quite impressive considering how rudimentary our equipment was.”

At this point, USAID bought into their vision and furnished Afriseed with a processing plant that could handle, sort, treat, and package seeds for both legume and maize. The company then pivoted to working with maize seed, based off the observation that most farmers were obtaining yields lower than the genetic potential of existing varieties.

“To do so,  it was quite clear that we needed an institution that could help us break into the maize seed industry dominated by large multinational seed companies,” Angomwile explains. “This led us to partner with CIMMYT, which is a partnership that still exists today and has enabled us to accelerate our market penetration strategy through providing us with high-performing drought-tolerant genetics which are growing in popularity among farmers.”

The impact of CIMMYT support

Since 2017, CIMMYT has been working with Afriseed to help smallholder farmers access new and improved varieties that are drought-tolerant and can withstand seasonal weather variations induced by climate change. “As CIMMYT, our role is not only to breed improved genetic material that farmers can take up, but also to support business development for the private sector through intensive capacity building programs that position such entities to be sustainable and to excel in the absence project support,” explains Hambulo Ngoma, an agricultural economist working with CIMMYT. The organization has provided Afriseed with two high performing varieties so far: AFS 635 and AFS 638. In addition, CIMMYT has supported Afriseed in stimulating demand within the smallholder farmer market through facilitating the establishment of demonstration plots and designing targeted seed marketing strategies.

During CIMMYT Director General Bram Govaerts’ recent visit to Zambia, Ngoma highlighted that the organization is aware that small-to-medium enterprises may be constrained with regards to marketing budgets and market development investments. “As such, when we are convinced that there is a business case and an opportunity for a food security transformation, we usually support promising entities such as Afriseed with knowledge and resources to stimulate demand,” he said. “This is of extreme importance as farmers growing old, recycled seed from ancient varieties need to transition to new, improved varieties.”

Govaerts said, “We are happy we could contribute to the success of Afriseed in our own small way and we hope our partnership will take you to the next level.”

Afriseed has since grown and now comprises nearly 200 workers: 90 permanent staff and 110 casual workers during the peak season. Production has surged to an excess of 10,000 metric tons per season and there is a growing customer base stretching throughout all regions of the country. Angomwile is very grateful to have had a partner like CIMMYT, which facilitated Afriseed’s membership to the International Maize Consortium (IMC), a global body that provides access to an expanded genetic pool bringing exposure to new genetic gains. “Being a member of IMC is definitely an advantage for us as an entity because the seed supply market is highly competitive,” she explains. “So, we can now quickly become aware of the new genetic materials available and ask our research and development team — established through the immense support from CIMMYT — to develop new varieties for our target market.”

Through a series of exchange visits and trainings, CIMMYT has mentored the research and development team who are now in a position to breed their own varieties without external support. “The number of farmers in high potential areas that are remotely located that are still growing recycled seed is still quite large,” says Peter Setimela, a seed systems specialist who was part of the mentoring team. “We need to continuously render extensive support to entities such as Afriseed such that the seed quality deficiency gap can be greatly reduced.”

As the rains have been in abundance during this 2022/23 season, there is high anticipation that farmers who have grown seed from reputable seed suppliers such as Afriseed, are set for a bumper harvest.

Goal 17 of the United Nations’ Sustainable Development Goals calls to “Strengthen the means of implementation and revitalize the global partnership for sustainable development”. The International Maize and Wheat Improvement Center (CIMMYT) answered this call to action by recently hosting a collaborative dinner to strengthen ties between the Center, the private sector and government partners in Malawi.

Hosted by CIMMYT Director General Bram Govaerts, the dinner followed a visit by US Special Envoy for Global Food Security Cary Fowler, Dina Esposito, Assistant to the Administrator, USAID Bureau of Resilience and Food Security and other USAID staff to discuss and witness the new Accelerated Innovation for Delivery Initiative (AID-I) in action.

“The challenges of today do not require a single sector approach but a pluralistic one in which partners from the private, public sectors agree to work hand in hand with science for impact organizations like CIMMYT and other CGIAR centers,” said Govaerts in his keynote address at the event. “I am very grateful for your support and your presence today is a testimony or our harmonious solidarity and spirit of collaboration in addressing food and nutrition security.”

The meeting was attended by seed industry players, agricultural input distributors, food processors and Government representatives including Director of Agriculture Research Services Grace Kaudzu, who expressed her appreciation for the gathering.

“As government, our role is to create an enabling environment for the private sector to thrive and progressive development partners are always welcome. Such gatherings enable us to hear the needs of colleagues and partners from other sectors to create this environment,” she said.

Malawi has established an ambitious roadmap where legume exports and maize production are to be significantly scaled up. The AID-I project dovetails with this roadmap as it focuses on strengthening maize and legume seed systems and addressing systemic constraints in both value chains.

The dinner further facilitated private sector players to meet various CIMMYT specialists ranging from seed system experts, soil scientists, breeders and plant physiologists. According to Peter Setimela, a seed system specialist at CIMMYT, such meetings are critical as they enable a diversity of partners to know what the other has to offer.

“CIMMYT has a lot of expertise which these private sector partners can take advantage of,” Setimela said.

The AID-I project seeks to scale up existing and high potential innovations, technologies and business models as opposed to initiating new ones. This only makes sense considering that the implementation period is only two years and scaling up existing innovations give greater prospects for success.

CIMMYT Regional Representative Moses Siambi labelled the event a success citing the huge turnout of the partners.

“The effectiveness of our interventions is dependent on the strength of the relationships we have with our partners. Such a massive attendance is indicative of cordial relations between CIMMYT and the private sector in conjunction with the government,” Siambi said.

Govaerts closed the event by stressing that through harnessing the potential of convening power, the future is bright regardless of the reality of climate change and geopolitical conflicts.

Farmers in Buhera gear up for climate-smart agriculture

As climate change effects intensify, new innovations that enable smallholder farmers to adapt are no longer an option but a necessity. Significant parts of Zimbabwe are semi-arid, receiving less than 600mm of rainfall per year. Smallholder farming communities in districts such as Buhera have embraced feed production and water conservation innovations deployed by the International Maize and Wheat Improvement Center (CIMMYT) as part of the Livestock Production Systems in Zimbabwe project (LIPS-Zim). The project, funded by the European Union and led by the International Livestock Research Institute (ILRI) and CIMMYT, champions the crop-related aspects of interventions and aims to increase livestock productivity in Zimbabwe’s semi-arid regions. The project specifically aims to promote increased adoption of climate-relevant innovations in livestock-based production systems and improved surveillance and control of livestock diseases. While focused on livestock, the project is based on the premise that the performance of the livestock sector depends heavily on crop husbandry. By the same token, the livestock sector has bi-products that directly impact the productivity of crops.

Zimbabwe is a country that is well suited to mixed farming systems. Most smallholder farmers have treated livestock and crop production as mutually exclusive, but the two enterprises can have a significant complementary effect on each other.

CIMMYT Cropping Systems Agronomist Isaiah Nyagumbo is leading the development of crop husbandry innovations aimed at increasing feed production that are poised to benefit smallholder farmers’ crop productivity and enhance the conditioning of livestock, especially cattle.

Despite extension recommendations for farmers not to grow maize in these regions, studies show that 60% of the arable land is still occupied by maize. This is due to maize’s popularity among farmers thanks to its diverse uses.

One solution is to support farmers with the most appropriate cultivars and most effective production technologies to help them be more resilient to climate change induced challenges. To contribute towards LIPS-Zim’s objective for increased feed production, CIMMYT scientists are testing and demonstrating the use of drought tolerant and nutritious maize varieties along with a wide range of leguminous species such as mucuna, dolichos lab-lab and cowpea, which are grown mostly as intercrops. Efforts are also being made to develop innovative water conservation options through reduced or no-till planting basins and tied ridging systems reinforced with different mulching options including conventional organic and synthetic artificial mulches. These are then being compared to traditional conventional mouldboard ploughing systems.

So far, the results are exciting and helping farmers to see the productivity gains from applying different technologies. Mr. and Mrs. Nyekete, smallholder farmers who volunteered to work with CIMMYT on these innovations, are optimistic about widespread adoption once the trials are concluded as the technologies can suit different levels of investment by farmers.

“We have a lot of farmers visiting us as they observe a diversity of technologies on our plot. The artificial mulch concept is one which is very new, and farmers are curious as to how it works. They can observe for themselves that, especially when used with tied ridges, it is very effective in retaining moisture,” said Mr and Mrs Nyekete.

“The same applies to organic mulch. Government extension workers have, over the years, been encouraging us to plant our maize under the Pfumvudza conservation agriculture model, and in it is the use of organic materials as mulch. The level of compliance in areas such as Buhera has been low, where people practice Pfumvudza without fully applying all the principles, especially soil cover. The water conservation trials are providing evidence that when one dedicates themselves to mulching their crop, whether using organic or synthetic mulches, the maize productivity is comparatively higher. As you can see, the maize plots with these water harvesting technologies are showing high vegetative growth in comparison to conventionally planted maize.”

Over the years, there has been a slow adoption of new innovations emanating from scientific research usually conducted on research stations. The use of on-farm research trials and demonstrations helps smallholder farmers to participate in the research process and co-create technologies, which shortens the adoption period and stimulates adoption at scale. This approach enables more farmers, who are not hosts, to benefit from the technologies showcased in the trials and to observe and learn from the trials. As the saying goes, “seeing is believing” and farmers can choose the options most relevant to their own circumstances.  As such, farmers can conclude for themselves which technologies bear results compelling enough for them to adopt.

Despite the artificial mulching technology demonstrating impressive results so far, Nyagumbo cautions that before the technology can be promoted at scale, more research, as well as proof of concept for these systems are needed.

“Firstly, we see that the quality of the material used has a big bearing on the ability to reduce evaporation from the soil. Secondly, some farmers have observed germination challenges due to the synthetic materials creating an attractive habitat for rodents that eat the maize seed before it germinates. Thirdly, the returns from such investments need to be justified by highly attractive economic returns arising from high yields that will also enable farmers to intensify their production systems by producing their food needs from much smaller areas. Further studies and analyses therefore need to be conducted,” said Nyagumbo.

“Furthermore, so far the idea of tied ridging combined with organic mulches also seems to offer a highly attractive option for farmers that will contribute to increased feed productivity from the enhanced grain and crop residues, since increased biomass output also means increased livestock feed availability.”

While breeding excellence is proving to be an effective method for responding to climate change through improved seed varieties and high-performance livestock breeds, new crop and livestock production technologies are required to complement the genetic gains from breeding. The crop production technologies being showcased in in Buhera along with drought tolerant and nutritious maize varieties and legumes, promise to be transformative for semi-arid regions for both crop and livestock systems.

Mini-tillers bolster Nepal maize farmers’ food supplies and profits, new study shows

Written by Mike Listman on . Posted in Publications.

Use of lightweight, 5-9-horsepower mini-tillers by smallholder farmers in Nepal’s mid-hills cut tillage costs and boosted maize yields by facilitating timely maize cultivation, thus enhancing food self-sufficiency and farm profits and reducing rural poverty, a new study by an international team of scientists shows.

Published in the Journal of Economics and Development, the study reports findings of an on-farm survey involving more than 1,000 representative households from 6 districts of the mid-hills, a region of steep and broken terrain where rainfed maize is a staple crop, outmigration of working-age inhabitants makes farm labor scarce and costly, and farmers on small, fragmented landholdings typically till plots by hand or using ox-drawn plows.

“Conventional two- or four-wheel tractors are difficult to operate in the mid-hills’ rugged topography,” said Gokul P. Paudel, researcher working together with the International Maize and Wheat Improvement Center (CIMMYT) and Leibniz University, Hannover, Germany, and lead author of the study. “Farms are small and the mini-tillers are a good fit. Very small farms — those comprising less than 0.4 hectares of land and normally not served by hired farm labor or larger machinery — benefited the most from mini-tiller adoption.”

The paper is the first to provide empirical linkages between small-scale farm mechanization and the UN Sustainable Development Goals, particularly No Poverty (SDG-1) and Zero Hunger (SDG-2).

“Given its rural poverty and the resulting outmigration from farm areas to cities and to other countries, Nepal has increasingly become a labor-exporting country,” explained Paudel, who partnered in this study with researchers from the Asian Development Bank Institute and Cornell University. “Our research can help guide investments by Nepal and other developing countries in scale-appropriate farm mechanization, supporting those who wish to remain on rural homesteads and make a go of it.”

The science team found that farm size, labor shortages, draft animal scarcity, and market proximity were major factors that facilitate the adoption of appropriate mechanization in Nepal, according to Tim Krupnik, CIMMYT systems agronomist and study co-author.

“Smallholder farms dominate more than two-thirds of agricultural systems globally,” Krupnik said. “Interest in scale-appropriate farm mechanization is growing rapidly, particularly among donors and governments, and practical empirical measures of its impact are crucial.” The findings of the latest study fill this knowledge gap and provide sufficient evidence to prioritize the spread of appropriate technologies among smallholder farmers.

Krupnik noted that, through its office in Nepal and strong shared research and capacity-building activities, CIMMYT has worked for almost four decades with Nepali scientists and development partners, including the Nepal Agricultural Research Council (NARC) and the Ministry of Agriculture and Livestock Development (MoALD), to raise the productivity and sustainability of the country’s maize- and wheat-based farming systems.

In addition to strong government partnerships, CIMMYT works closely in Nepal with a range of non-government organizations, and importantly, hand-in-hand with private farm machinery manufacturers, retailers, and mechanics.

The study described was supported by the Bill & Melinda Gates Foundation, the US Agency for International Development (USAID), the Academy for International Agricultural Research (ACINAR) commissioned by the German Federal Ministry for Economic Cooperation and Development (BMZ) and carried out by ATSAF e.V. on behalf of the Deutsche Gesellschaft fur Internationale Zusammenarbeit (GIZ) GmbH, the One CGIAR Regional Integrated Initiative Transforming Agrifood Systems in South Asia (TAFSSA), and generous funders who contribute to the CGIAR Trust Fund.

Farmers harvested double yield by adopting Wengkhar Hybrid Maize 1 in Bhutan

Written by Sarah McLaughlin on . Posted in Features.

The planting of maize hybrid Wengkhar Hybrid Maize 1 (WHM-1) has helped farmers in the Mongar district of Bhutan double their maize yield.

WHM-1 was developed in partnership with the International Maize and Wheat Improvement Center (CIMMYT) and became the first maize hybrid to be released in Bhutan to combat the negative effect of increasing temperature or extreme heat events on maize.

The hybrid was designed with characteristics of heat and drought tolerance, as well as a resistance to stem and root lodging. It also had additional stay-green traits after cob maturity and produced a high yield.

The success of the implementation in Bhutan is leading to an increased production of WHM-1, which will aim to meet national demand and work towards country’s self-sufficiency.

Dechen Yangden is one of the smallholder beneficiaries in Tsakaling, a sub-district in Mongar in the east of the country, who have boosted their maize yield by planting WHM-1. “My attempt to grow WHM-1 has doubled my maize production compared to last season where I cultivated some other maize varieties (2.5 metric tons (mt) in one hectare (ha)),” she said.

Farmers’ experiences of WHM-1

Since its official release in 2020, the national maize program based at Agriculture Research & Development Center (ARDC) started producing hybrid seeds and maintaining parental lines. To test the success of the ARDC’s work, planting was carried out in the Tsakaling and Waichur hamlets in Mongar districts, covering an area of six acres.

Maize farmers in Tsakaling shared that although the crop was affected by the insect fall armyworm during the early vegetative stage, the productivity of the crop was not affected, as it recovered at later stage.

Meanwhile, ARDSC Khangma carried out yield monitoring during the harvest, where WHM-1 yielded 5.8 mt ha-1, which is noticeable rise on the national average of 3.7 mt ha-1.

Following the conclusion of their harvest, farmers in the two localities shared their views on the newly released maize in order to review the effect of the implementation of WHM-1. Both sets of growers reported an improved performance from the use of WHM-1 and noted that, unlike other maize varieties, the hybrid has shorter and uniform plant height along with a higher resistance to lodging, which is an essential trait given the conditions it is grown in. Furthermore, the stay-green trait of the hybrid after maturity of cobs gave farmers an added advantage of green fodder, which can be used for feeding their cattle.

In Waichur, the growers found that this hybrid had a tight husk and fully filled kernels. They shared similar views to growers in Tsakaling, reporting positive lodging resistance in the hybrid.

Both communities expressed their interest in continuing to use WHM-1, given the availability and accessibility of the seeds. As a response, the National Maize Program at ARDC Wengkhar, is looking to deploy the newly released hybrid on a larger scale, which will ultimately contribute towards enhancing maize self-sufficiency in the country.

WHM-1 was developed through partnership of the National Maize Program at Wengkhar and CIMMYT under the Heat Stress Tolerant Maize for Asia (HTMA) project for germplasm and technical assistance and the Commercial Agriculture and Resilient Livelihoods Enhancement Program (CARLEP-IFAD/MoAF) for on-farm research and intensification.

Feasibility mapping for WHM-1 showed that its adaption stretches along the southern foothills and some parts of eastern district. The National Maize Program, sister research centers, and farmers are currently working on upscaling the seed production for intensification of national maize production to meet the domestic demands.

Cary Fowler, Special Envoy for Global Food Security, and Dina Esposito, the United States Agency for International Development (USAID) Global Food Crisis Coordinator, discussed the US strategy for addressing the global food security crisis and their ongoing visit to Malawi and Zambia at a digital press briefing on January 19.

“We’ve recently supported a new project which will be operating in a number of countries, including Zambia and Malawi, that will be coordinated by the International Maize and Wheat Improvement Center, and by the International Institute of Tropical Agriculture,” said Fowler.

“They’ll be establishing innovation hubs where they’ll bring together the best and most appropriate technologies and information to help small-scale farmers with a whole variety of issues that they confront. This will give the farmers access, for example in Zambia, to drought-tolerant maize, which they’re really clamoring for. This is maize which, on a year-in and year-out basis, on average will yield about 30 percent more, rotated with legumes, which provide protein and also enrich the soil and reduce the need for fertilizer. But also other technologies and assistance in establishing markets for those products and lengthening out the value chain so that farmers are not just – and small businesses are not just dealing with raw commodities but are taking those commodities and making something more valuable and more useful to a broader population.”
