Ethiopian researchers travel to India to strengthen knowledge regarding increasing wheat productivity

The irrigated lowlands of Afar and Oromia in Ethiopia are vital areas for the cultivation of wheat and increasing their productivity is crucial to attaining food security in the light of extended drought and other climate shocks.

Adaptation, Demonstration, and Piloting of Wheat Technologies for Irrigated Lowlands of Ethiopia (ADAPT-Wheat) is a three-year project funded by Germany’s Federal Ministry for Economic Cooperation and Development with the objective of identifying, verifying, and adopting wheat technologies that increase wheat production and productivity in Afar and Oromia.

As part of ADAPT-Wheat’s capacity building mission, four Ethiopian wheat researchers from different disciplines visited the Indian Central Soil Salinity Research Institute (CSSRI), the Indian Institute of Wheat and Barely Research (IIWBR), Land force (Dasmesh Mechanical Works), the Borlaug Institute for South Asia (BISA), and National Agro Industries from 13 -22 March 2024.

At CSSRI, the researchers learned how to reclaim salt-affected soils through the use of salt tolerant crops, improve management of water usage, and employ cover crops in salt-affected soils to reduce soil temperature and evapotranspiration. They also visited a sodic and saline microplot facility used to screen genotypes under the desired salinity and sodicity stresses. The researchers witnessed ongoing activities such as agrochemical/ biological/hydraulic technologies to reclaim salt-affected soils, the use of poor-quality irrigation water for crop production and the adoption of ameliorative technologies for salinity management.

The Ethiopian researchers also attended an international conference organized by the Indian Society of Soil Salinity and Water Quality, “Rejuvenating salt affected soil ecologies for land degradation neutrality under changing climate.”

They learned about breeding methods, and advances in yield enhancement, disease resistance, sustainable agricultural practices, innovative farming methods, genetic stocks developed for grain protein, iron, and zinc enhanced wheat varieties, phytic acid levels, gluten strength, and grain texture.

At Dasmesh Mechanical Works, they learned the operation and maintenance of equipment ADAPT-Wheat has purchased from Dasmesh, including machines for plowing, land leveling, planting, and threshing.

The visit to BISA included an introduction to Conservation Agriculture methods, such as fertilizer use efficiency and crop residue management, which will ultimately help improve productivity back in Ethiopia. They also viewed an ongoing experiment on Precision–Conservation Agriculture Based Maize-Wheat Systems.

Finally, the researchers visited the CIMMYT-India office and met with Mahesh Kumar Gathala, systems agronomist and lead scientist.

“We are proud to host our Ethiopian colleagues. Collaborating with them allowed us to learn as much from them as they hopefully learned from us during their visit,” said Gathala.

For Daniel Muleta (irrigated wheat project coordinator), Shimelis Alemayehu (agronomist), Hailu Mengistu (wheat breeder) and Lema Mamo (soil scientist) all from Ethiopian Institute of Agricultural Research (EIAR), the visit to India was beyond their imagination and gave them the opportunity to participate in salinity workshop, visited different institutions and gained experience. Shimelis said “even though the workshop was for experience sharing the travel made was beyond that”.

The team acknowledged CIMMYT-Ethiopia and CIMMYT India offices and EIAR management.

CGIAR’s “GDI Oscars” celebrate the stars behind advancing Gender, Diversity and Inclusion in our workplaces

More than 200 staff came together to celebrate the winners of CGIAR’s first-ever Inclusive Workplace Awards on September 15 at a special online ceremony that rolled out the red carpet from Peru to Penang.

In early June, a call for nominations went out across CGIAR for the Inclusive Role Model, Inclusive Leader, and Inclusive Team Awards, each with clearly stated selection criteria.

When the nomination period closed in early July, more than 150 staff had submitted nominations – indicating the value of CGIAR’s collective work towards creating even more inclusive workplaces.

“It’s our very own GDI Oscars,” said co-host Fiona Bourdin-Farrell, CGIAR’s Global Director of People and Culture, setting the celebratory tone in the first few minutes of the event.

“The Inclusive Workplace Awards allow us to recognize the stars among us who have demonstrated in words and deed their personal commitment to advancing gender, equity and inclusion in our workplaces.”

Inclusive Team Award

The final award of the day, the Inclusive Team Award, went to the CIMMYT Women in Crop Science Team for proactively adopting better ways of working to create an inclusive and respectful team culture.

Members of CIMMYT’s award-winning Women in Crop Science group.

Accepting the award on behalf of the team, Alison Bently, Director of CIMMYT’s Global Wheat Program, said that the Women in Crop Science Team grew out of the significant underrepresentation of women in crop science.

“We established the group to identify and try to collectively address some of the causes of underrepresentation,” she said. “And importantly,” she added “to develop tangible actions broadly covering operational equality, recruitment and retention, and raising awareness and visibility.”

Winding up her acceptance remarks, Alison said: “I think it’s important to say that there’s much work that remains to be done. But the CIMMYT Women in Crop Science Team is committed to working with and supporting colleagues here at CIMMYT, across the CG[IAR], and in the international community to build a more inclusive and diverse community.”

As crop yields are pushed closer to biophysical limits, achieving yield gains becomes increasingly challenging. Traditionally, scientists have worked on the premise that crop yield is a function of photosynthesis (source), the investment of assimilates into reproductive organs (sinks) and the underlying processes that enable and connect the expression of both. Although the original source-and-sink model remains valid, it must embrace more complexity, as scientific understanding improves.

A group of international researchers are proposing a new wiring diagram to show the interrelationships of the physiological traits that impact wheat yield potential, published on Nature Food. By illustrating these linkages, it shows connections among traits that may not have been apparent, which could serve as a decision support tool for crop scientists. The wiring diagram can inform new research hypotheses and breeding decisions, as well as research investment areas.

The diagram can also serve as a platform onto which new empirical data are routinely mapped and new concepts added, thereby creating an ever-richer common point of reference for refining models in the future.

“If routinely updated, the wiring diagram could lead to a paradigm change in the way we approach breeding for yield and targeting translational research,” said Matthew Reynolds, Distinguished Scientist and Head of Wheat Physiology at the International Maize and Wheat Improvement Center (CIMMYT) and lead author of the study. “While focused on yield potential, the tool can be readily adapted to address climate resilience in a range of crops besides wheat.”

Breeding milestone

The new wiring diagram represents a milestone in deterministic plant breeding. It dovetails simpler models with crop simulation models.

It takes into account how source and sink strengths may interact with wheat developmental stages to determine yield. For example, at the time of stem growth, spike growth or effective grain filling.

This diagram can be used to illustrate the relative importance of specific connections among traits in their appropriate phenological context and to highlight major gaps in knowledge. This graphical representation can also serve as a roadmap to prioritize research at other levels of integration, such as metabolomic or gene expression studies. The wiring diagram can be deployed to identify ways for improving elite breeding material and to explore untapped genetic resources for unique traits and alleles.

Yield for climate resilience

The wheat scientific community is hard at work seeking new ways to get higher yields more quickly to help the world cope with population growth, climate change, wars and stable supplies of calories and protein.

“To ensure food and nutritional security in the future, raising yields must be an integral component of making crops more climate-resilient. This new tool can serve as a roadmap to design the necessary strategies to achieve these goals,” said Jeff Gwyn, Program Director of the International Wheat Yield Partnership (IWYP).

Bangladesh could largely reduce greenhouse gas emissions from agriculture while increasing efficiency in production

A number of readily-available farming methods could allow Bangladesh’s agriculture sector to decrease its greenhouse gas emissions while increasing productivity, according to a new study by the International Maize and Wheat Improvement Center (CIMMYT) and partners.

The study, published in Science of the Total Environment, measured the country’s emissions due to agriculture, and identified and analyzed potential mitigation measures in crop and livestock farming. Pursuing these tactics could be a win-win for farmers and the climate, and the country’s government should encourage their adoption, the research suggests.

“Estimating the greenhouse gas emissions associated with agricultural production processes — complemented with identifying cost-effective abatement measures, quantifying the mitigation scope of such measures, and developing relevant policy recommendations — helps prioritize mitigation work consistent with the country’s food production and mitigation goals,” said CIMMYT climate scientist Tek Sapkota, who led this work.

To determine Bangladesh’s agricultural greenhouse gas emissions, the researchers analyzed 16,413 and 12,548 datapoints from crops and livestock, respectively, together with associated soil and climatic information. The paper also breaks down the emissions data region by region within the country. This could help Bangladesh’s government prioritize mitigation efforts in the places where they will be the most cost-effective.

“I believe that the scientific information, messages and knowledge generated from this study will be helpful in formulating and implementing the National Adaptation Plan (NAP) process in Bangladesh, the National Action Plan for Reducing Short-Lived Climate Pollutants (SLCPs) and Nationally Determined Contributions (NDC),” said Nathu Ram Sarker, director general of the Bangladesh Livestock Research Institute.

Policy implications

Agriculture in Bangladesh is heavily intensified, as the country produces up to three rice crops in a single year. Bangladesh also has the seventh highest livestock density in the world. In all, the greenhouse gas output of agriculture in Bangladesh was 76.79 million metric tons of carbon dioxide equivalent (Mt CO2e) in 2014-15, according to the research. This emission is equivalent to the emission from fossil fuel burning by 28 million cars for a year.  At the going rate, total agricultural emission from Bangladesh are expected to reach 86.87 Mt CO2e by 2030, and 100.44 Mt CO2e by 2050.

By deploying targeted and often readily-available methods, Bangladesh could mitigate 9.51 Mt and 14.21 Mt CO2e from its agriculture sector by 2030 and 2050, respectively, according to the paper. Further, the country can reach three-fourths of these outcomes by using mitigation strategies that also cut costs, a boon for smaller agricultural operations.

Adopting these mitigation strategies can reduce the country’s carbon emissions while contributing to food security and climate resilience in the future. However, realizing the estimated potential emission reductions may require support from the country’s government.

“Although Bangladesh has a primary and justified priority on climate change adaptation, mitigation is also an important national priority. This work will help governmental policy makers to identify and implement effective responses for greenhouse gas mitigation from the agricultural sector, with appropriate extension programs to aid in facilitating adoption by crop and livestock farmers,” said Timothy Krupnik, CIMMYT country representative in Bangladesh and coauthor of the paper.

Mitigation strategies

The research focused on eight crops and four livestock species that make up the vast majority of agriculture in Bangladesh. The crops — potato, wheat, jute, maize, lentils and three different types of rice — collectively cover more than 90% of cultivated land in the nation. Between 64 and 84% of total fertilizer used in Bangladesh is used to cultivate these crops. The paper also focuses on the four major kinds of livestock species in the country: cattle, buffalo, sheep and goats.

For crops, examples of mitigation strategies include alternate wetting and drying in rice (intermittently irrigating and draining rice fields, rather than having them continuously flooded) and improved nutrient use efficiency, particularly for nitrogen. The research shows that better nitrogen management could contribute 60-65% of the total mitigation potential from Bangladesh’s agricultural sector. Other options include adopting strip-tillage and using short duration rice varieties.

For livestock, mitigation strategies include using green fodder supplements, increased concentrate feeding and improved forage/diet management for ruminants. Improved manure storage, separation and aeration is another potential tool to reduce greenhouse gas emissions. The mitigation options for livestock would make up 22 and 28% of the total potential emission reductions in the sector by 2030 and 2050, respectively.

Crop breeding and soil management must go hand in hand

There is a growing crisis beneath our feet. Scientists, soil specialists and policy-makers around the world are sounding the alarm about degrading soil conditions. And it is particularly stark in developing countries. In fact, about 40 per cent of soils in sub-Saharan Africa are already of poor quality.

Declining soil health causes poor crop yields, leading to further pressure on the soils as farmers struggle to meet food demands and eke out a living. Many farmers lack access to information or technologies to get out of this vicious cycle. If you are a farmer with the need to increase your yield in the face of these challenges, crop breeding and soil management offers a range of solutions as part of an Integrated Soil Fertility Management (ISFM) approach.

For instance, breeding programs which partner with CGIAR Excellence in Breeding (EiB) are working to deliver the best seed varieties for farmers to help them withstand harsh conditions and increase yields. Alongside this work, researchers are supporting farmers to adopt better agronomic practices, such as minimum tillage farming, crop rotation, proper spacing and planting date practices, the use of terracing or intercropping, or techniques to reduce water use.

Of course, breeding cannot happen in a vacuum. To protect soils and produce quality yields, these cropping measures should be closely matched to the best, context-appropriate soil management practices available to farmers, for instance around the type and timing of mineral fertilizer, along with organic sources like crop residues, compost or manure.

Indeed, a combination will bring the best results.  But most of the time accessing either improved variety or best agronomic practice represent a challenge for farmers in low income countries.

Here are three ways crop breeders can ensure they deliver the best seeds and create the best conditions for long-term crop production.

Include farmers, agronomic experts and extension services when defining product requirements

Strong connections among public breeding programs and extension and agronomic groups are vital. There is growing discussion regarding how to broaden our work to better consider all the factors that contribute to a successful breeding scheme: genotyping, environment and management (GxExM). However, defining the management component is not easy. Do we breed for conditions that farmers are actually working with, or breed for conditions that they should adopt?

A key to answer this question is a strong breeding team defining the traits needed and wanted by farmers. To design the best product profile, it is imperative to involve extension teams and other groups that work on the development of sustainable agronomic practices.

Properly manage research stations

Attention also needs to focus on the sustainability practices within research stations. It is all too easy to find degraded soil in public research stations. There are many reasons for this: inadequate long-term planning, lack of organized management structures, insufficient connections between breeding and agronomic teams, and lack of resources, to name a few.

Public research stations must serve as an example for the farmers in that specific region. Thus, it is not only what products we develop that matters, but also how we develop them. If we develop a good variety at the research station, but do so without adopting good agronomic practice, what example has been set for farmers and future generations? We need to ensure we invest in the best soil management practices along every step of the research phase.

Breed for specific soil characteristics

Once the breeding target is known, breeding for specific soil conditions is critical. This means developing varieties for soil conditions such as nutrient deficiencies or high salinity levels. CGIAR breeding programs have put in tremendous efforts with great impact here.

For example, AfricaRice and partners developed rice varieties branded ARICA (Advanced Rice Varieties for Africa) to be salt or iron toxicity tolerant, among other traits. This is helping farmers who farm under predominantly rainfed conditions, in which soils and yields are threatened by floods, droughts and toxicity.

Another standout product is Stress Tolerant Maize for Africa (STMA), led by the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute of Tropical Agriculture (IITA). Breeders have developed varieties that can thrive in low soil fertility conditions, along with resistance to other stresses such as pests and drought. The project has seen the adoption of new maize varieties by more than six million households across 13 countries, with some farms increasing yields by over 150 per cent.

Our soils depend on breeding for the future. Breeding is showing real results for improving yields, delivering better food, and increasing smallholder incomes. But its impact on ecosystems could go either way. With the right investments in relationships, good research practices, and delivering varieties matched to particular soil conditions, we can breed for the present and for the future.

It is time to invest in both crop breeding and soil management — as one vital package of innovations.

Scientific opportunities and challenges

The first meetings of the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) wheat and maize science and technical steering committees — WSC and MSC, respectively — took place virtually on 25th and 28th September.

Researchers from the International Maize and Wheat Improvement Center (CIMMYT) sit on both committees. In the WSC they are joined by wheat experts from national agricultural research systems (NARS) in Bangladesh, Ethiopia, Kenya, India, and Nepal; and from Angus Wheat Consultants, the Foreign, Commonwealth & Development Office (FCDO), HarvestPlusKansas State University and the Roslin Institute.

Similarly, the MSC includes maize experts from NARS in Ethiopia, Ghana, Kenya and Zambia; and from Corteva, the Foundation for Food and Agriculture Research (FFAR), the International Institute for Tropical Agriculture (IITA), SeedCo, Syngenta, the University of Queensland, and the US Agency for International Development (USAID).

During the meetings, attendees discussed scientific challenges and opportunities for AGG, and developed specific recommendations pertaining to key topics including breeding and testing scheme optimization, effective engagement with partners and capacity development in the time of COVID-19, and seed systems and gender intentionality.

Discussion groups noted, for example, the need to address family structure in yield trials, to strengthen collaboration with national partners, and to develop effective regional on-farm testing strategies. Interestingly, most of the recommendations are applicable and valuable for both crop teams, and this is a clear example of the synergies we expect from combining maize and wheat within the AGG project.

All the recommendations will be further analyzed by the AGG teams during coming months, and project activities will be adjusted or implemented as appropriate. A brief report will be submitted to the respective STSCs prior to the second meetings of these committees, likely in late March 2021.

Webinar explores continuous improvement approach to plant breeding

A recent webinar organized by the CGIAR Excellence in Breeding Platform (EiB) and Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project, invited national agricultural research systems, seed companies, other interested breeders to explore tools, techniques and transitions toward a continuous improvement culture in breeding.

Continuous improvement (CI) is an approach that is being used to modernize breeding programs, to ensure they consistently get significantly improved varieties in farmers’ fields. It helps teams create a new way of thinking and working. The goal is to ensure striving for excellence becomes part of an organizational culture. To get there, CI provides a set of clear principles and tools to help diagnose problems and then solve them.

The webinar featured a leading international CI expert —Theresa Heitman, an EiB consultant — who introduced the Lean Improvement Methodology, an approach to help breeders grow their programs and improve results without adding more resources. It examines the way breeders create value for the customer, using specific methods and tools to reduce or eliminate non-value added activities.

Other presenters included B.M. Prasanna from the CGIAR Research Program on Maize, Gustavo Teixeira and Theresa Heitman from EiB and Dan Makumbi from EiB and the International Maize and Wheat Improvement Center (CIMMYT), Marcelo Almeida from Syngenta, and Sharifah Shahrul from the International Rice Research Center (IRRI).

The CI webinar is part of a series of webinars co-organized by EiB and AGG. Forthcoming sessions will cover assessing genetic gains and other topics.
