CIMMYT wishes to announce that the start of the planting season for the 2015A planting season at the KALRO–CIMMYT maize lethal necrosis (MLN) artificial inoculation screening site at Naivasha, Kenya. Interested organizations from both the private and public sectors are invited to send their maize germplasm for screening. Planting is due to start at the end of May 2015 following an upgrade of the current irrigation system. Please note that it can take up to six weeks to process imports and clear shipments..
The MLN Screening Facility is the largest of its kind established in response to the MLN outbreak in eastern Africa in 2013. It supports countries in sub-Saharan to screen maize germplasm (hybrids, inbreds, and open pollinated varieties) against MLN in a quarantined environment. The facility is managed jointly by the Kenya Agricultural and Livestock Research Organization (KALRO) and CIMMYT, and was established with support from the Bill & Melinda Gates Foundation and the Syngenta Foundation for Sustainable Agriculture. Since its inception in 2013, the facility has evaluated more than 20,000 accessions from more than 15 multinational and national seed companies and national research programs.
For assistance in obtaining import permits and necessary logistics for the upcoming screening, please contact Biswanath Das

EL BATAN, Mexico (CIMMYT) – Artist Katharine McDevitt, creator of a new bronze representation of wheat scientist Norman Borlaug, is fascinated by sculptures representing pre-Hispanic deities – so much so that she relocated to Mexico from the United States to learn more about the ancient art form.
She studied, and then taught, sculpture at “La Esmeralda,” the National School of Painting, Sculpture and Engraving in Mexico City, where renowned Mexican artists Frida Kahlo and Diego Rivera taught in the 1940s.
The Chapingo campus, in the city of Texcoco about 30 kilometers (20 miles) from Mexico City, is home to a mural painted by Rivera in the 1920s titled “Fertile Land.”
Sculptor McDevitt says her personal pre-Hispanic favorite is a 16th century basalt depiction of the Aztec earth goddess Coatlicue, associated with agriculture, the cycle of life, the mother of the moon, stars and Huitzilopochtli, the god of war, sun and human sacrifice. The 2.6-meter (8.5-foot) tall sculpture, housed in Mexico’s National Museum of Anthropology, represents Coatlicue decapitated, snakes emerging from her neck, clad in a skirt of snakes and a necklace of human hearts, hands and a skull.
“I’m always very moved by pre-Hispanic sculpture, I find it very powerful – it’s a language that speaks across boundaries of culture, you can feel the tremendous energy,” said McDevitt, who has also made her own pantheon of deities, including the Diosa del Maíz statue at Chapingo.
The massive stone Coatlicue sculpture is a far cry from her own gentle tribute in bronze to a more contemporary agricultural giant – 1970 Nobel Peace Prize laureate Norman Borlaug – which was unveiled in the presence of his daughter Jeanie Laube Borlaug and members of the international wheat community at CIMMYT headquarters near Texcoco last week.
Borlaug, who died in 2009 at age 95, led efforts that began at CIMMYT in Mexico to develop high-yielding, disease-resistant, semi-dwarf wheat varieties in the mid-20th century. His successes, which earned him the title “Father of the Green Revolution,” are estimated to have helped save more than 1 billion lives in the developing world.
The life-size sculpture is based on an emblematic photograph of the scientist, McDevitt said. Borlaug, originally from Iowa, is wearing a familiar hat, jotting down notes in a book and wearing a class ring from the University of Minnesota where he earned his graduate degrees. The wheat stalks at his feet were made from casts of wheat plants of the varieties used for the Green Revolution, McDevitt said.
“This is the most inspiring figure I’ve ever had the privilege of doing,” McDevitt said, adding that she considers Borlaug a modern god of agriculture. “This project has been the greatest honor of my career. There was a lot of input from CIMMYT staff who knew Dr. Borlaug well. They offered suggestions, useful comments and tips on how to make the sculpture more life-like, how to make it more faithful to who Dr. Borlaug was.”
McDevitt also designs and produces pre-Hispanic rituals at the Chapingo Autonomous University, including a graduation ritual designed around Tlaloc, the Aztec god of rain, water, lightning and agriculture. Each August, McDevitt designs a welcome ritual for new students based around the story of Xilonen, the corn goddess.
In 2001, Borlaug participated in an interactive seed sowing-ritual inspired by Rivera’s murals. As part of the ritual, which occurs every year on Agronomy Day on February 22, a hand – created by McDevitt – emerges from furrows of earth, laid out in the National Agricultural Museum.
Three life-size versions of McDevitt’s Borlaug statue exist. One is in Ciudad Obregon in the northern Mexican state of Sonora and the other is in Delhi, India. A small number of miniature replicas have been distributed to recognize important achievements of key contributors to global food security, including 2014 World Food Prize laureate Sanjaya Rajaram, a former student of Borlaug’s at CIMMYT.

CIUDAD OBREGON, Mexico (CIMMYT) — Martin Kropff, who will take the helm as director general of the International Maize and Wheat Improvement Center (CIMMYT) in June, joined scientists, and other members of the global wheat community at the CIMMYT experimental research station near the town of Ciudad Obregon in Mexico’s northern state of Sonora for annual Visitors’ Week.
Following a tour of a wide range of research projects underway in the wheat fields of the Yaqui Valley made famous around the world by the work of the late Nobel Peace Prize winner Norman Borlaug, who died in 2009 at age 95, Kropff shared his views.
Borlaug led efforts to develop high-yielding, disease-resistant, semi-dwarf wheat varieties in the mid-20th century that are estimated to have helped save more than 1 billion lives in Pakistan, India and other areas of the developing world.
“I’m very impressed by what I’ve seen in Obregon,” said Kropff, who is currently chancellor and vice chairman of the executive board of Wageningen University and Research Center in the Netherlands.
“From the gene bank in El Batan, the breeding and pre-breeding and the work with farmers on a huge scale, it’s extremely high quality and innovative,” added Kropff, who with his wife Nynke Nammensma also visited CIMMYT’s El Batan headquarters near Mexico City earlier in the week.
“The MasAgro program is very impressive because it takes the step of integrating scientific knowledge with farmers’ knowledge – it’s a novel way to aid farmers by getting new technology working on farms at a large scale. It is a co-innovation approach,” Kropff said.
The Sustainable Modernization of Traditional Agriculture, led by country’s Secretariat of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA) and known locally as MasAgro, helps farmers understand how minimal soil disturbance, permanent soil cover and crop rotation can simultaneously boost yields and sustainably increase profits.
“The program is an example of how farmers, scientists and other stakeholders can think about and create innovations through appropriate fertilizer applications, seed technologies and also through such instruments as the post-harvesting machines,” Kropff said.
“This is fantastic. That’s what the CGIAR is all about.”

“The HarvestPlus program, which adds more zinc and iron into the crop through breeding, also plays a key role in CIMMYT’s research portfolio,” Kropff said.
Zinc deficiency is attributed to 800,000 deaths each year and affects about one-third of the world’s population, according to the World Health Organization. Enhancing the micronutrient content in wheat through biofortification is seen as an important tool to help improve the diets of the most vulnerable sectors of society.
The climate change adaptation work he observed, which is focused on drought and heat stress resilience is of paramount importance, Kropff said.
Findings in a report released last year by the Intergovernmental Panel on Climate Change state it is very likely that heat waves will occur more often and last longer throughout the 21st Century and that rainfall will be more unpredictable.
Mean surface temperatures could potentially rise by between 2 to 5 degrees Celsius or more, the report said.
“To safeguard food security for the 9 billion people we’re expecting will populate the planet by 2050, we need innovations based on breeding, and solid agronomy based on precision farming,” Kropff said.
“There’s no other organization in the world that is so well designed as the CGIAR to do this type of work. CIMMYT is the crown jewel of the CGIAR together with the gene banks. No other organization can do this.”
“We’ve done a lot of work in getting higher yields, but not much through increased yield potential, and that’s what we have to work on now,” he added.
“If you raise the yield through agronomy, you still need to enhance yield potential and there’s very good fundamental work going on here.”
“The partnerships here are excellent – scientists that are here from universities are as proud as CIMMYT itself about all the work that is being done. I’m really honored that from 1 June, I have the opportunity to be the director general of this institution. I cannot wait to get started working with the team at CIMMYT and I’m extremely grateful for the warm welcome I’ve received – a smooth transition is already underway.”

Christian Thierfelder, CIMMYT senior agronomist stationed at Harare, Zimbabwe, was recently profiled by the Canadian Foodgrains Bank for his work promoting conservation agriculture techniques for smallholder farmers in Africa. Conservation agriculture systems are not only better for soils but help make agriculture more ‘climate-smart’, argues Thierfelder. “The conventional system can only make use of the water that is in the ridge and not further down in the soil,” he said. “In conservation agriculture systems, there is access to deeper layers and a lot of water has infiltrated. The maize can actually access the water much better because of an improved root system.”
In addition, the techniques can provide far-reaching food security benefits to smallholder farmers. As conservation agriculture diminishes the risk of crop failure, it also allows farmers to reduce the land devoted to maize and to diversify the crops they produce. “Then there is room for new crops, cash crops, rotational crops, nutritional crops that help them to improve their diets and reduce malnutrition,” Thierfelder said. “That’s a very good way to overcome all of these problems at once.”To read the full article, click here.
The Food and Agriculture Organization of the United Nations (FAO) has tasked CIMMYT with a new project to introduce green manure cover crops to smallholder farmers in eastern Zambia and central and southern Malawi.
Green manures can improve fertility, protect soils and provide fodder and grain for farm animals and humans. They also help substitute for mineral fertilizers, which are costly for landlocked African nations to produce or import. Most smallholder farmers cannot afford them and apply less than 10 kg per hectare of fertilizer to their crops, according to a 2013 study on profitable and sustainable nutrient management systems for eastern and southern African smallholder farming systems.
“This is less than one-tenth of average fertilizer rates in prosperous countries and a key reason why maize yields in southern Africa are around only one ton per hectare,” said Christian Thierfelder, CIMMYT conservation agriculture specialist based in southern Africa. “As a result, many farm families in the region remain food insecure and caught in a seemingly unbreakable cycle of poverty.”

With full participation of farmers, the project will test green manures in rotation with maize and as intercrops or relay crops in different farming systems, according to Thierfelder.
“Improved, high-yielding maize can show its potential only under good agronomic practices, such as optimal plant spacing, timely planting, good weed and pest control and adequate fertilization,” Thierfelder explained. “Farmers in Europe and the Americas have followed these basic principles for generations, and some of the ideas spread to Asia and Africa during the Green Revolution. But in Africa mineral fertilizers are most often used by rich farmers and for high-value crops.“
“Improved maize that tolerates drought and other stresses, coupled with conservation agriculture practices –minimum soil disturbance, crop residue retention and diversification through rotations and intercropping systems – are farmers’ best bet to escape the poverty trap,” Thierfelder said.
Keeping crop residues on the soil is a critical component of conservation agriculture, but the residues are traditionally fed to livestock, which also underpin smallholder farmers’ livelihoods. So the use of conservation agriculture hinges on the ability of a cropping system to produce enough biomass to feed farm animals while providing an adequate residue cover. This requires a source of fertilization to feed the cropping system.
The FAO-CIMMYT project will address this by allocating green manure cover crops for different uses. “Over the last five years, CIMMYT’s global conservation agriculture program has identified potential cover crop varieties that fit farmers’ needs,” Thierfelder said. “Velvet bean, lablab, cowpea, sunnhemp or jackbean can provide 10-50 tons per hectare of extra biomass for livestock. They can also leave 50-150 kilograms per hectare of nitrogen in the soil and do not need any additional fertilizer to grow. Finally, lablab and cowpea provide grain that humans can eat.”
One approach Thierfelder promotes is for a farmer to dedicate part of her land to grow maize under conservation agriculture practices, and other areas to sow green manures, nutritional and cash crops that increase soil fertility and household income. “In this way, a farmer can diversify and gradually have money to purchase mineral fertilizer, boost productivity and move out of poverty.”
Green manure cover crops are not new in Africa. Why should they work this time?
According to Thierfelder, there are examples of success in northern Mozambique with CIMMYT’s partner organization CARE International, using lablab and improved germplasm in cassava-based CA systems can increase cassava tuber yields from 4 to 13 tons per hectare, without using additional mineral fertilizer. “In Tanzania, lablab and other green manures are an important part of the cropping system,” he said. “In Zimbabwe, successful experiments with maize and green manures under an ACIAR-funded ZimCLIFFS project also provide hope. The FAO-CIMMYT project will guide the way on integrating green manures cover crops into these farming systems.”
A testament to increased climate variability and risk for farming systems already operating on the razor’s edge, the 2014-15 cropping season will be recognized as a sad write-off by most farmers in Central Mozambique. The rains started six weeks late and most of the rainfall fell in only two months (normally it’s distributed over four), followed by a long drought and some few showers at the end.
But with funds from the CGIAR Research Program on Maize, partners from the Instituto de Investigação Agrária de Moçambique (IIAM) and CIMMYT are working with farmers in Manica Province, Mozambique, to test and promote conservation agriculture practices that better capture and retain precious precipitation, among other advantages.
As part of this, they have revived “mother-baby” trials, a participatory methodology pioneered over a decade ago by CIMMYT for testing drought tolerant maize in Africa and which was subsequently adapted for diverse agronomic practices and is used by researchers worldwide.

Comprising field experiments grown in farming communities, mother-baby trials feature a centrally-located mother trial that is set up with researchers’ support. Baby trials, which contain subsets of the mother-trial treatments, are grown, managed and evaluated by interested farmers.
Moving from “business as usual” to innovation
In Machipanda, a small village in Manica on the border with Zimbabwe, IIAM maize breeder Dr. David Mariote established three mother trials, each with two conservation agriculture-based systems and a conventional control plot, combined with four maize varieties from the Drought Tolerant Maize for Africa (DTMA) project, which is funded by the Bill & Melinda Gates Foundation, and a traditional variety, in full rotation with cowpeas.
Farmers then put up the baby trials from a menu of practices that included direct seeding with no tillage, crop rotations, residue retention, herbicide applications, fertilizer use and improved varieties. Interest was high: 54 farmers grew baby trials and some even extended their plots beyond the designated areas, in the excitement of trying something new, according to Mariote.
“Conditions are changing fast; business as usual is no longer an option,” Mariote said. “We have to offer improved technologies that farmers can use to mitigate negative effects from climate change and improve their lives.”
Mariote witnessed first-hand the synergistic benefits of combining conservation agriculture and drought tolerant maize, as part of work in the Platform on Agriculture Research and Technology Innovation (PARTI), a project funded through the US Agency for International Development (USAID) via Feed the Future and implemented by CIMMYT in Central and northern Mozambique.

With training from CIMMYT’s global maize program and technical backstopping from the CIMMYT global conservation agriculture program, Mariote sought new and stronger ways to spread these technologies. That’s when he hit upon mother-baby trials, which had never been used before with drought tolerant maize and conservation agriculture in tandem.
Farmers who grew baby trials unanimously agreed that new ways of farming are needed and that the trials had been eye-openers. In a community meeting, some said: “We often do not have money to buy expensive fertilizers but we have seen that with good agronomic practices and good maize varieties we can already increase our maize yields.”
More farmers in Machipanda have signed up for future baby trials and, as a clear indication of commitment and excitement about conservation agriculture and improved maize, they will use their own inputs to grow them.
Irrigation reservoir at the Kulumsa research station in Ethiopia. CIMMYT/Julie Mollins
KULUMSA, Ethiopia (CIMMYT) — An irrigation reservoir at the Kulumsa Agricultural Research Center in Ethiopia’s highlands captures water from a nearby beer distillery about 168 km (105 miles) southeast of the capital Addis Ababa.
Before the irrigation project was constructed, the industrial runoff from the brewery poured into the nearby river and affected the health of local residents.
Now it nourishes crops growing in neighboring fields during the dry season or in periods of drought. It can store up to 38,195 m3 of water.
“The irrigation project has been a key investment – it’s very instrumental for accelerating seed multiplication of improved high-yielding rust resistant varieties for local wheat projects,” said Bekele Abeyo, a CIMMYT senior scientist and wheat breeder.
“It allows us to advance wheat germplasm and seed multiplication of elite lines twice a year, which we couldn’t do previously.”
This cuts the time by half from the currently required eight to 10 years to four to five years for the development and release of new varieties through conventional breeding.
An additional pond with the capacity to capture 27,069 m3 of natural water from the river, generates the capacity to irrigate more than 30 hectares of land during the off season.
The construction of the ponds began in April 2012. Sprinkler irrigation was completed in 2014 and management of the project was handed over to the Kulumsa Research Center.
Climate-smart agriculture can be “an effective tool to address climate change and climate variability,” according to Kai Sonder, head of CIMMYT’s geographic information systems (GIS) unit, who was one of 754 participants from 75 countries, including 39 CIMMYT representatives, at the third annual Global Science Conference on Climate-Smart Agriculture, held in Montpellier, France, during 16-18 March.
“Challenges are different for developing and developed countries, but climate change is affecting all of us,” said Sonder. Millions of smallholder farmers in developing countries have less than one hectare of land, earn less than USD $1 per day and are highly vulnerable to extreme climatic events. Many farmers in developed countries struggle to make a living, are dependent on subsidies and insurance payouts and are also highly vulnerable to extreme climatic events.
Modern agriculture, food production and distribution are major contributors of greenhouse gases, generating about one-quarter of global emissions. Climate-smart agriculture addresses the interlinked challenges of food security and climate change by sustainably increasing agricultural productivity, building resilience in food-production systems and reducing greenhouse gas emissions in agriculture.
Challenges and areas where climate-smart agriculture has yet to take hold were addressed at the conference. “California has not practiced it for 50 years and is now dealing with the consequences of poor groundwater management,” said Sonder. “Likewise, Ciudad Obregón and Sinaloa in Mexico are fully-irrigated areas in the middle of a desert where climate-smart practices need to be implemented on a larger scale based on CIMMYT’s activities with local partners.”
Progress and exhibitions on climate-smart agriculture projects were also showcased. “This is becoming an integral part of CIMMYT work, as climate conditions increasingly disrupt growing seasons,” Sonder said. “MasAgro is looking at water and nutrient efficiency in Mexico, and CIMMYT is developing maize and wheat varieties that are tolerant to stresses like heat and drought and their combinations,” said Sonder. In collaboration with the CGIAR Research Program on Climate Change, Food Security and Agriculture (CCAFS), CIMMYT has also piloted 27 climate-smart villages in Haryana, India, which will disseminate key climate-smart agricultural interventions.
The conference also allowed potential partners to meet and identify areas for future cooperation. Sonder mentioned interactions with Jacob van Etten, Senior Scientist at Bioversity International, who works on climate change and climate-smart agriculture in Costa Rica and uses iButton sensors to measure climate data in the field. “Such cheap and effective devices can allow us to reach more places, and I’d like to use them to monitor storage and humidity conditions in metal silos for CIMMYT’s Effective Grain Storage Project in eastern and southern Africa, as well as in the postharvest activities of MasAgro in Mexico,” said Sonder
A new project in Ethiopia aims to improve the livelihoods of wheat farmers by encouraging the development and multiplication of high-yielding, rust-resistant bread and durum wheat varieties.

High-quality seed is the key entry point for elevating farmer productivity in Ethiopia. As Norman Borlaug, the late Nobel Peace Prize laureate and wheat breeder who worked for many years with the International Center for Maize and Wheat Improvement (CIMMYT) wrote: “Rust never sleeps.”
Stem, leaf and yellow rusts choke nutrients and devastate wheat crops without recognition of political boundaries, making it essential that global action is taken to control all virulent strains of these devastating diseases to ensure food security.
At a recent workshop hosted by the Ethiopian Institute of Agricultural Research (EIAR) in the capital, Addis Ababa, 150 participants from 24 organizations discussed the project, which builds upon the successes of a previous EIAR and International Center for Agricultural Research in the Dry Areas (ICARDA) program funded by the U.S. Agency for International Development (USAID).

The purpose of the March workshop titled “Seed Multiplication and Delivery of High-Yielding Rust-Resistant Bread and Durum Wheat Varieties to Ethiopian Farmers” was to launch the three-year seed project, which has a budget of $4.75 million, and strengthen the involvement of stakeholders and key partners.
Aims include enhancing rust disease surveillance, early warning and phenotyping; fast-track variety testing and pre-release seed multiplication; accelerating seed multiplication of durable rust-resistant wheat varieties; demonstrating and scaling up improved wheat varieties; and improving the linkages between small-scale durum wheat producers and agro-industries.
To achieve these goals EIAR, CIMMYT and the University of Minnesota will implement project activities in collaboration with other key Ethiopian stakeholders, including agricultural research centers, public and private seed enterprises, the Ethiopian Agricultural Transformation Agency, the Ethio-Italian Development Cooperation “Agricultural Value Chains Project in Oromia” and the Ethiopia Seed Producers Association.
The project covers 51 districts in four major wheat-growing regions of Ethiopia. Milestones include the following: reaching 164,000 households with direct access to the new technology and having more than 2 million households benefiting from indirect access to high-yielding rust resistant cultivars; wheat yield increases of 25 percent for farmers with access to rust-resistant seed varieties; training for about 5,000 agricultural experts, development agents, seed producers and model farmers; more than 50 percent of the wheat area being sown to cultivars with durable resistance to current rust threats; an increased number of seed growers and associations participating in accelerated seed multiplication; and the increased participation of women farmers to lead accelerated seed multiplication and scaling up.
All partners will be involved in close monitoring and working groups related to the project.
At the workshop, a key topic was emphasizing to farmers that they must avoid susceptible rust suckers as they are pumping more spores on cultivars under production, which is one reason for the recurrent epidemics of wheat rusts and break down of resistant genes.
Delegates also engaged in discussions on the importance of cropping systems and variety diversifications. Fruitful deliberations and interactions occurred and important feedback was captured for project implementation and to ensure successful results.
A previous workshop on the surveillance, early warning and phenotyping component of the project was held at the Cereal Disease Laboratory in Minnesota.
Bekele Abeyo is a CIMMYT senior scientist based in Addis Ababa, Ethiopia. He will lead the seed improvement project.
Benefits of three decades of international collaboration in wheat research have added as much as 10.7 million tons of grain – worth US $3.4 billion – to China’s national wheat output, according to a study by the Center for Chinese Agricultural Policy (CCAP) of the Chinese Academy of Science.
Described in a report published on 30 March by the CGIAR Research Program on Wheat, the research examined China’s partnership with CIMMYT and the free use of CIMMYT improved wheat lines and other genetic resources during 1982-2011. The conclusions are based on a comprehensive dataset that included planted area, pedigree, and agronomic traits by variety for 17 major wheat-growing provinces in China.
“Chinese wheat breeders acquired disease resistant, semi-dwarf wheat varieties from CIMMYT in the late 1960s and incorporated desirable traits from that germplasm into their own varieties,” said Dr. Jikun Huang, Director of CCAP and first author of the new study. “As of the 1990s, it would be difficult to find anything other than improved semi-dwarf varieties in China. Due to this and to investments in irrigation, agricultural research and extension, farmers’ wheat yields nearly doubled during 1980-95, rising from an average 1.9 to 3.5 tons per hectare.”
The new study also documents increasing use of CIMMYT germplasm by wheat breeders in China. “CIMMYT contributions are present in more than 26 percent of all major wheat varieties in China after 2000,” said Huang. “But our research clearly shows that, far from representing a bottleneck in diversity, genetic resources from CIMMYT’s global wheat program have significantly enhanced China varieties’ performance for critical traits like yield potential, grain processing quality, disease resistance and early maturity.”
WILL CHINA WHEAT FARMING RISE TO RESOURCE AND CLIMATE CHALLENGES?

The world’s number-one wheat producer, China harvests more than 120 million tons of wheat grain yearly, mainly for use in products like noodles and steamed bread. China is more or less self-sufficient in wheat production, but wheat farmers face serious challenges. For example, wheat area has decreased by more than one-fifth in the past three decades, due to competing land use.
“This trend is expected to continue,” said Huang, “and climate change and the increasing scarcity of water will further challenge wheat production. Farmers urgently need varieties and cropping systems that offer resilience under drought, more effective use of water and fertilizer, and resistance to evolving crop diseases. Global research partnerships like that with CIMMYT will be vital to achieve this.”
Dr. Qiaosheng Zhuang, Research Professor of Chinese Academy of Agricultural Science (CAAS) and a Fellow of Chinese Academy of Science, called the new report “…an excellent, detailed analysis and very useful for scientists and policy makers. CIMMYT germplasm and training have made a momentous contribution to Chinese wheat.”

Borlaug Institute for South Asia (BISA) and CIMMYT India staff members gathered together at NASC Complex, New Delhi to pay tribute to the late Dr. Norman E. Borlaug on what would have been his 101st Birth Anniversary on 25 March. HS Gupta, director general, BISA, garlanded Borlaug’s statue, in front of the office block at NASC Complex. Staff members offered flowers in respect to the Nobel Laureate. Gupta apprised the staff members about Borlaug’s great contributions, including high-yielding wheat varieties which helped solve hunger around the world and particularly in South Asia. BISA and CIMMYT staff members resolved to work hard and follow Borlaug’s footsteps.

CIMMYT and the Borlaug Institute for South Asia (BISA) have jointly developed and launched an application for Android called “N Calculator,” to support smallholder farmers using the GreenSeeker, a compact sensor to quickly assess crop vigour and calculate optimal fertilizer dosages. Held in the CIMMYT-CCAFS climate-smart village (CSV) Noorpur Bet of Ludhiana, Punjab, India, the launch was led by John Snape, CIMMYT Board Chair.
The Greenseeker ensures accurate and balanced nitrogen fertilizer applications, cutting farmers’ costs, reducing nitrification and nitrogen runoff into groundwater and water systems, and raising crop yields. But smallholder farmers often lack the training to interpret the raw data from the GreenSeeker. N Calculator automatically calculates the best nitrogen and urea rate using normalized difference vegetation index (NDVI) values from GreenSeeker, and right on a mobile handset.
“The application will help scale out GreenSeeker technology and precision nitrogen management in wheat-based systems in South Asia, among other things reducing emissions of nitrous oxide, a potent greenhouse gas,” said M.L. Jat, CIMMYT cropping systems agronomist. “It will also be critical for extension agents to scale out climate-smart agriculture practices across the region.”
Delegates including the BISA Executive Committee and national scientists interacted with farmers and members of farmer cooperatives who are actively disseminating climate-smart agriculture practices.
Participants included S. Ayyapan, DG (ICAR); Thomas A Lumpkin, director general, CIMMYT; Marianne Bänziger, deputy director general for research and partnerships, CIMMYT; Nicole Birrel, CIMMYT board member; Anthony De Sa IAS, Chief Secretary of Madhya Pradesh; B.S. Dhillon, Vice Chair of Punjab Agricultural University (PAU); Suresh Kumar, Additional Chief Secretary of Punjab; B.S. Sidhu, Agriculture Commissioner of Punjab; and H.S. Gupta, Director General, BISA.

This week, CIMMYT had the honor of hosting Dr. Eliud Kireger, the Acting Director General of the Kenya Agricultural and Livestock Research Organization (KALRO). His visit included travel to the experiment station at Ciudad Obregón for first-hand experience regarding CIMMYT wheat research, as KALRO is one of the few partners in Africa with whom we work on both maize and wheat.
According to Kireger, a burning issue in agriculture today in eastern and southern Africa is “low productivity per unit area. The increase we’ve seen in yields in different countries is largely due to expansion in land area.” He attributed this low productivity per unit area to lack of technologies or knowledge that can boost productivity. This dearth translates itself in many ways, such as low use of fertilizers, improved seed, or mechanization.

Accompanying Kireger was Stephen Mugo, CIMMYT–Africa Regional Representative who also doubles as country representative for Kenya. Mugo lauded the benefits of the CIMMYT–KARLO synergy. “There is no single institution — working alone — that can be able to address all the challenges facing agriculture,” Mugo said. “From early on, CIMMYT decided that the only way was to team up with national institutions and work together, so that CIMMYT-developed germplasm and technologies reach intended beneficiaries countrywide for the benefit of maize and wheat farmers. CIMMYT and KALRO jointly design common projects on clear and specific areas to improve maize and wheat, then seek funding for these projects to address drought tolerance, crop pests and emerging diseases.”
One such emerging disease is maize lethal necrosis (MLN), which CIMMYT and KALRO are jointly tackling through ultra-modern shared facilities for MLN screening and for doubled haploid technology that both stand on KALRO land.
Southern Africa smallholder farmers can attain food security and more income through sustainable intensification of maize-based farming systems. This was revealed during recent field learning tours in Malawi and Mozambique last month. On show were farmer-tested improved maize–legume technologies being disseminated by CIMMYT’s Sustainable Intensification of Maize-Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) project.

Smallholder farmers interacted with non-governmental organizations and private-sector partners who have shown a great interest in the SIMLESA outscaling approach using lead farmers and learning sites. Some of the sites promote smallholder agriculture development by linking farmers with buyers and agrodealers, and by providing access to credit and technical training.
Conservation agriculture (CA) exhibited mixed fortunes and presented more opportunities for learning and information sharing. Due to the excessive rains experienced in January, maize on the conventional ridge and furrow farming systems was generally greener and taller than on the CA plots, although the positive rotation effects in CA were clearly evident from the healthy maize crop following soybeans. Also, some maize varieties under CA were more susceptible to diseases such as leaf rust and suffered more from pests such as white grubs which attacked maize roots.

Main points from the learning tours included:
Linking the smallholder farmer to input and output markets is an integral part of SIMLESA Phase II’s smallholder commercialization thrust.
The participation of private-sector companies in SIMLESA demonstrations is a vital exit strategy to ensure sustainability and continued engagement with smallholders.
CA technologies performed rather poorly in periods of excessive rainfall, and particularly so for nitrogen-starved crops.
Using different maize varieties could help SIMLESA recommend the best CA-ready maize cultivars capable of tolerating diseases and pests in CA systems.
Malawi’s Principal Secretary for Agriculture, Erica Maganga, led a delegation of Government Principal Secretaries and seed company representatives to Mpilisi and Ulongue in Balaka District on 11 March to observe progress in conservation agriculture (CA) adoption, as part of the country’s Agriculture Sector Wide Approach Program (ASWAP).

“CIMMYT is on the forefront in promoting different options to farmers… previous challenges will now not be an issue here as farmers have been exposed to different solutions,” said Maganga, after seeing the benefits of a trial in Ulongue where maize is grown under CA using different types of residues. Over the last several years the country has actively pursued CA, implementing practices that include eliminating traditional ridge-and-furrow tillage systems, keeping crop residues and rotating maize with leguminous crops.
Malawi is smaller than the state of Pennsylvania, yet supports 17.4 million people, half of whom live below the poverty line. Global climate change has disrupted the country’s traditional rain cycles, resulting in longer droughts or extreme floods. Maize is Malawi’s primary food crop, but unpredictable weather causes longer “hungry seasons” – the months until the next maize harvest, after the previous year’s grain has been eaten. With 85% of Malawian farmers depending upon rain-fed agriculture, erratic weather jeopardizes food security and livelihoods.

The Malawian government and farmers are working vigorously to address climate variability and support projects in affected communities. One example is Tiyanjane Nutrition Group, a beneficiary of CIMMYT’s ReSEED Maize Project funded by USAID. The group is involved in small-scale farming, value addition and sale of baked goods. Farmers use the proceeds to help orphans and other people in need and to buy inputs for better farming.
“CIMMYT through ReSEED is demonstrating drought-tolerant maize varieties to farmers,” Maganga said. “I want to urge seed companies to be proactive in providing these new maize varieties to farmers.”
The delegation also visited farmers who adopted CA practices such as intercropping pigeonpea with maize. Other demonstrations showcased crop diversification, promotion of indigenous crops, nutrient management, good agriculture practices and construction of infiltration pits and lowland tracts to manage water runoff and filter pollutants.
