As a fast growing region with increasing challenges for smallholder farmers, Asia is a key target region for CIMMYT. CIMMYT’s work stretches from Central Asia to southern China and incorporates system-wide approaches to improve wheat and maize productivity and deliver quality seed to areas with high rates of child malnutrition. Activities involve national and regional local organizations to facilitate greater adoption of new technologies by farmers and benefit from close partnerships with farmer associations and agricultural extension agents.

ISLAMABAD — CIMMYT’s Agricultural Innovation Program (AIP) held its annual maize working group meeting on 10-11 May with over 20 representatives from public and private seed companies and higher learning institutions in attendance. The working group evaluated AIP partners’ progress in deploying CIMMYT-derived maize hybrids and varieties to farmers.
Maize productivity in Pakistan has increased almost 75 percent since the early 1990s thanks to the adoption and expansion of hybrid maize varieties. However, the seed that spurred this growth is largely imported at an annual cost of $50 million. Since AIP’s launch in 2013, however, more than 80 CIMMYT-derived maize hybrids and open-pollinated varieties have been adapted to Pakistan’s diverse ecologies. Currently, 21 public- and private-sector companies are testing and deploying these locally-adapted cultivars to smallholder farmers across the country.
In his opening statement, Pakistan Agricultural Research Council (PARC) Chairman Nadeem Amjad cited AIP as the best example of sustainable development projects and said that one of its invaluable contributions is “sharing of valuable parental lines and breeder seeds.” He added that CIMMYT hybrids can help “resource-poor maize farmers have affordable maize seeds at their doorstep.”

At the meeting, partners reported on their progress producing parental seed and described how they planned to deliver quality seeds to farmers. They also identified key challenges in Pakistan’s maize seed value chain and recommended potential solutions during the group discussion.
In his concluding remarks, Pakistan’s National Agricultural Research Center (NARC) Director General Muhammad Azeem Khan said that it was only thanks to AIP innovations and interventions that NARC was able to start producing seed of biofortified hybrid maize, a first in the history of Pakistan.
Certificates of appreciation were presented by AIP to NARC for jump-starting hybrid seed production in Pakistan and hosting various national maize events in 2015, as well as to Tara Crop Sciences (Pvt.) Ltd. for conducting the best maize trials evaluated by AIP maize partners during the 2015 traveling maize seminar.

Maize is the second most important food crop in Nepal, after rice. It contributes approximately 25 percent of Nepal’s food basket and occupies around 26 percent of the total cropped area. Maize productivity (2.3 tons per hectare) in Nepal is still quite low compared to the global average of 5.5 tons per hectare (t/ha).
Growing demand from Nepal’s poultry industry cannot be met by growing only open-pollinated varieties. Because of their high productivity, quality and profitability, higher-yielding hybrids have become increasingly popular among farmers. However, most maize hybrids are only approved for sale and cultivation in the central and eastern Terai, east of the Narayani River. To meet market demand, farmers in many areas, especially in western Nepal, sometimes purchase non-approved hybrid seeds. These hybrid seeds are not registered at Nepal’s Seed Quality Control Centre and are traded through informal channels.
Not wishing to risk a government penalty for violating the seed policy, traders have not distributed many high-performing hybrids, thereby restricting their local production, fair distribution and widespread availability, which could benefit many farmers in Nepal. Of the estimated 2,500 tons of hybrid maize grown in Nepal annually, only 1,000 tons are registered hybrids.
In 2014 and 2015, the CIMMYT-led Cereal Systems Initiative for South Asia (CSISA) and Nepal’s National Maize Research Program (NMRP) partnered to evaluate maize hybrids in six additional districts (Banke, Bardiya, Kailali, Kanchanpur, Surkhet and Dadeldhura) in western Nepal. Trials were conducted in spring in the Terai and in summer in the mid-hills; they were monitored by a team of NMRP stakeholders. Performance data for variety release and registration were shared with Nepal’s National Seed Board (NSB).
Of the ten hybrids evaluated, four (TX 369, Bioseed 9220, Rajkumar and Nutan) were found to be agronomically superior, producing more than 6 t/ha. They also had tight husk cover, which provides moderate resistance to northern leaf blight and grey leaf spot. Based on the evaluation results, the NSB has registered and approved the four hybrid varieties for sale in western Nepal.
Highlighting the need to increase farmers’ access to registered hybrids, Dilaram Bhandari, NSB member and Director of the Crop Development Directorate of Nepal’s Department of Agriculture, said, “We have to adopt this modality for other hybrids as well, since new hybrids expand outside the recommendation domains quite frequently.”

DHARWAD, INDIA — Nearly 150 scientists, researchers and extension agents from universities and agricultural departments across the state of Karnataka, India, attended a field training 12-13 April on conservation agriculture and farm mechanization for sustainable intensification. The training was hosted by the University of Agricultural Sciences (UAS), Dharwad, Karnataka, and jointly organized by CIMMYT, UAS and Karnataka’s Department of Agriculture.
South Asia is one of the most vulnerable regions to climate change. Flooding and drought coupled with seasonal rainfall changes are predicted to devastate agriculture, with extreme heat already disrupting the growing season in India and other countries. Wheat production in India’s Indo-Gangetic Plains may decrease by up to 50 percent by 2100, harming the hundreds of millions who rely on the region for food security. India also extracts more groundwater than any other country in the world to support agriculture, with northern India’s groundwater declining one meter every three years.
Karnataka faces these and other challenges, including production system constraints, mono-cropping and lack of access to markets, storage facilities, processing units and real-time information. Other constraints include large post-harvest losses, labor and energy shortages, poor mechanization and fodder scarcity.
J.V. Goud, Ex Vice Chancellor, UAS, Dharwad, described these challenges in his inaugural address and emphasized the need for sustainable agriculture practices to achieve food security in India.
“Courses like this help combat climate anomalies and make agriculture practices drought-proof,” said Goud. Sustainable practices have proven successful in addressing water shortages in agriculture. For example, trainees were introduced to precision land leveling, which can raise India’s wheat yields more than 16% and increase water productivity by 130%.

According to M.L. Jat, CIMMYT senior cropping systems agronomist and an expert in conservation agriculture (CA), “Climate-smart agriculture practices such as CA not only minimize production costs and inputs, but also help farmers adapt to extreme weather events, reduce temporal variability in productivity, and mitigate greenhouse gas emissions, This is backed up by ample data on conservation agriculture management practices throughout the region.”
Conservation agriculture is sustainable and profitable agriculture based on minimal soil disturbance, permanent soil cover and crop rotations. It is improving farmers’ livelihoods throughout South Asia and has led to policy-level impacts through the implementation of CA practices covered in the training, such as precision land leveling, zero tillage, direct seeding and crop residue management.
Trainees were taught how to operate a variety of CA machines, including multi-crop zero-tillage machines that can calibrate the amount of seed and fertilizer and control speed for seeding different crops. They also learned about other practices such as weed, nutrient and water management using precision support and sensors.
Scientists and researchers who imparted the training included Jat, CIMMYT agronomist H.S. Jat, CIMMYT hub manager S.G. Patil, CIMMYT consultant Yogesh Kumar Singh, Borlaug Institute for South Asia (BISA) senior research engineer H.S. Sidhu, BISA senior scientist R.K. Jat and Deputy Director of the International Plant Nutrition Institute’s India Program-South Zone, T. Satyanarayana.
HYDERABAD, INDIA — A training course on maize seed production and seed business management was organized by CIMMYT and seed companies Pioneer Hi-bred and Kaveri Seeds from 28-30 March, 2016. The training was held as part of the CIMMYT’s efforts to connect several public and private sector agricultural research institutions in South Asia.
South Asian farmlands have been increasingly experiencing climate change-related weather extremes. If current trends persist until 2050, major crop yields and the food production capacity of South Asia will decrease significantly – by 17 percent for maize – due to climate change-induced heat and water stress. In response to this situation, CIMMYT with support from the United States Agency for International Development and partners are developing heat stress-resilient maize for Asia.
The course aimed to strengthen the capacity of partner institutions – particularly small-and-medium enterprises and national agricultural research systems in South Asia – to expand their maize seed production processes and increase uptake of heat-resilient maize hybrids in stress-prone areas. More than 20 participants from partner institutions participated in the course including breeders, seed production specialists and seed business specialists from commercial seed companies, including Syngenta, DuPont Pioneer, Advanta, J.K. Seeds, CIMMYT and the International Crops Research Institute for the Semi-Arid Tropics.
“Public-private alliances are critical to address complex issues such as heat stress and the development and deployment of heat stress-resilient maize in different regions of South Asia,” said P.H. Zaidi, CIMMYT’s Heat Stress Tolerant Maize for Asia (HTMA) project leader and senior maize physiologist. Zaidi also presented HTMA updates and listed the first variety releases licensed in 2015 to various partners for deployment.
Selvarajan Venkatesh, DuPont Pioneer senior maize breeder, gave a talk on commercial plant breeding and its business perspective with respect to sustainability and foundation for global food security. Venkatesh elaborated on how modern sophisticated hi-tech tools and interactions with multidisciplinary departments changed the face of present plant breeding. Nagesh Patne, CIMMYT seed system project Scientist, discussed the importance of seed production research and the optimization process of the cost of goods of seeds. Various aspects of plant characterization for seed production feasibility were also discussed during this meeting.

Other topics including maintenance breeding, production workflow, hybrid seed production, post-harvest management of seed lots and seed quality control were also discussed at the training. Presenters included A.R. Sadananda, CIMMYT, Satish Hegde, Advanta Seeds Pvt. Ltd., Ramana Rao, G.K. Seeds, S. Sudhakar Reddy, Field Crops Lead, Advanta India and R. Nanda Kumar, product quality and control manager with Syngenta India.
HARARE — Several African nation ambassadors to Zimbabwe pledged to step up support for improved agriculture technologies during a visit to The International Maize and Wheat Improvement Center’s (CIMMYT) Southern Africa Regional Office (CIMMYT-SARO) in Harare, Zimbabwe, in April.
The special field day and meeting, held as part of CIMMYT 50 celebrations, gave ambassadors from 12 African countries (Algeria, Botswana, Democratic Republic of Congo, Ethiopia, Namibia, Nigeria, Sudan, South Sudan, Tanzania, Uganda, South Africa and Zambia) the opportunity to learn about CIMMYT projects that are helping to strengthen food systems in sub-Saharan Africa and discuss future initiatives.
During the visit, the need to develop policies that promote smallholder farmers’ access to technologies that enable them to increase yields and improve crop resilience in the face of challenges such as droughts, as well as policies to address poverty, food security and economic growth surfaced as main priorities for the countries represented.

In his welcome address, Mulugetta Mekuria, CIMMYT-SARO regional representative, pointed out, “Sub-Saharan Africa’s food security faces numerous challenges, but drought is the most devastating because our farmers rely on rainfed agriculture. As you will see, CIMMYT’s work has created high-level impacts. But a host of challenges still hamper socioeconomic growth, such as reduced funding of agricultural research.”
According to Mekuria, CIMMYT’s work in sub-Saharan Africa aims to ensure farmers can access improved maize seed with drought tolerance and other relevant traits that contribute to higher, more stable yields, as well as technologies such as optimal fertilizer application. He noted that farmers in sub-Saharan African countries lag behind other regions in fertilizer application, applying, on average, less than 10 kg per hectare, which is 10 percent of the world average.
Another issue brought up was the lack of funding of agricultural research for development by most bilateral agencies on which African governments depend. The diplomats pledged to advise their governments of the need to increase support for improved agricultural technologies. They agreed that funding agricultural research work in line with the 2006 Abuja Declaration to allocate at least 1 percent of the donor country’s gross domestic product to agricultural research is of the utmost importance. Enhancing access to markets, extension services and inputs and supporting women and youth in agriculture were also identified as fundamental policy issues that need to be urgently addressed. Strong partnerships and collaborative efforts between various African governments, CIMMYT and the private sector were also called for.
The ambassadors were briefed on CIMMYT’s achievements in the region, and how, in partnership with national agricultural research systems and private seed companies, they have released more than 200 drought-tolerant maize varieties that perform significantly better under moderate drought conditions than varieties already on the market, while yielding the same – or better – in a normal season. More than 6 million farmers in sub-Saharan Africa grow improved drought tolerant maize varieties developed by CIMMYT and partners.
A wide range of CIMMYT-SARO technologies were also showcased, including sustainable intensification strategies based on the principles of conservation agriculture. Compared to conventional cropping practices, conservation agriculture increases yields after two to five cropping seasons due to the combined benefits of minimum soil disturbance, crop residue retention and crop rotation. Conservation agriculture has been successfully promoted in Malawi, Mozambique, Zambia and Zimbabwe for the past 10 years. For example, yield increases of 20-60 percent were recorded in trials in farmers’ fields in Malawi, while in Zambia and Zimbabwe, yields increased by almost 60% using animal traction innovation agriculture technologies.
Other technologies demonstrated were pro-vitamin A maize and quality protein maize. The diplomats learned that CIMMYT had released eight pro-vitamin A hybrids with 28% more vitamin A content in Zambia (4), Malawi (3) and Zimbabwe (1). On improved varieties, CIMMYT sent 823 seed shipments (1.3 million envelopes) to 835 institutions worldwide over the last four years.
“The success of our projects goes beyond the breeding work. Through the value chain approach, our work now is to ensure that seed companies and, ultimately, maize farmers benefit from the seed that is developed with their needs in mind. Getting drought-tolerant maize and other improved seeds to the markets and farmers is a critical next step,” said James Gethi, CIMMYT seed systems specialist.

Mark Bell, representative of University of California Davis, outlined some areas in which nudging, a technique that influences people towards desirable behavior, can be used as a potential vehicle for agriculture extension.
The technical session of the seminar was jointly chaired by Muhammad Imtiaz and Abdul Saboor, Dean of the Social Science Faculty, PMAS-UAAR.
Speaking during the technical session, Imtiaz described the nudging concept and the difference between nudging and incentivizing. He explained in detail the types of decisions made by the farming community and their implications for crop and livestock productivity. He spoke about AIP’s nudging efforts and how successful they have been in the livestock, vegetable and cereal sectors. He explained how farmers are nudged through AIP to increase agricultural productivity. The participants lauded AIP’s efforts to nudge farmers to adopt innovations and increase their productivity.

CHENGDU, CHINA – The International Maize and Wheat Improvement Center (CIMMYT), in collaboration with the Sichuan Academy of Agricultural Science (SAAS) is expanding conservation agriculture (CA) practices to promote sustainable intensification (SI) (i.e., agriculture aimed at enhancing the productivity of labor, land and capital) in China’s Sichuan Province.
Sustainable intensification can simultaneously address a number of pressing development objectives, including adapting production systems to climate change, sustainably managing land, soil, nutrient and water resources, improving food and nutrition security and ultimately reducing rural poverty. Zero tillage (ZT) minimizes soil disturbance, provides continual residue soil cover and includes crop rotations, all of which increases soil fertility and water use efficiency and helps cereal farmers sustain their crop yields over the long term.
As part of a joint CA project with CIMMYT, Tang Yonglu, Dean of the Crop Research Institute, SAAS, and his team have promoted sustainable mechanization and residue management, incorporated farmer input and hosted demonstrations in the rainfed regions of Sichuan. As a result, farmers from Mianyang District in Sichuan are now interested in ZT; a plan was thus put in place to build capacity and help farmers plant ZT maize and rice in May and June 2016.
Chaosu inspects an immature ZT wheat field affected by frost. This crop will be followed by ZT mechanically transplanted rice into the standing residue in late May. Previously, rice was manually transplanted by women following conventional inversion tillage. This new planting scheme tested by CIMMYT in Northwestern China will save 1-2 weeks and considerable input costs for the new ZT farmers in Southwest China. Photo: Jack McHugh/CIMMYT
At an annual SAAS-CIMMYT meeting, Tang’s team presented their findings on the effect soil compaction and waterlogging have on wheat production. Soil compaction occurs when random wheeling over cropping areas of farm vehicles, such as tractors and harvesters, packs the soil so tightly that soil conditions deteriorate, reducing crop yields. Waterlogging caused by flooding or intense rain on degraded soils also negatively affects yields.
At the meeting, CIMMYT proposed managing soil compaction through controlled traffic farming (CTF), an essential ZT practice that alleviates soil degradation. CTF permanently separates the crop area and the traffic lanes, thereby avoiding vehicle-induced soil compaction and improving and sustaining soil health. SAAS plans on implementing CTF as one tool in its sustainable intensification efforts.
During the two-day event, local researchers presented their academic and work reports and attended a field demonstration on advances in ZT mechanization; technical training sessions for farmers were also held. Other researchers addressed subjects such as soil health, weed control, sustainable techniques for rainfed wheat and mechanization techniques for rainfed maize.
Field demonstrations compared the performance of crops sown using locally produced one-pass planting machines and the Chinese made Turbo Happy Seeder. It was the first time participating researchers and farmers had seen a demonstration of the Happy Seeder. The Chinese seeder minimizes soil disturbance and uses devices that block residue, which makes it very useful for planting irrigated and rainfed crops when high levels of residue are maintained in the fields. For the locally produced machines to operate successfully, they require low levels of residue on the soil surface or that residues be incorporated into the soil.
Differences in planting machinery performance were difficult to discern in the wheat fields, due to yield losses across the region as a result of a very cold period in January. What was apparent was that while all the machines were equally effective in terms of crop establishment, there appeared to be slight differences in water stress in crops sown by the rotary till planter (high soil disturbance) and the non-rotary planter (low soil disturbance). This improvement in crop soil water was not lost on the participants as they strolled through the fields while listening to Li Chaosu, senior researcher at the Crop Research Institute, SAAS, explain the results.
CIMMYT SAAS collaboration is set to expand in the mountainous regions of Sichuan Province later this year, when new farmers come on board to implement ZT rice transplanting. The Green Farming Association, in collaboration with the local Agricultural Mechanization Bureau based in Santai, is also forging ahead with its conservation agriculture plans with CIMMYT’s guidance and support.

KATHMANDU, NEPAL (CIMMYT) – Farmers in Nepal are benefiting from the work done by the Cereal Systems Initiative of South Asia (CSISA) in Nepal, which promotes public-private partnerships with small and medium enterprises in the seed sector to aid sustainable intensification of wheat- and maize-based cropping systems over the past two years.
Representatives of these enterprises have received business mentoring, participated in an exercise on creating business plans, collaborated with Indian seed companies and attended a “theory of change” workshop. Subsequently, two seed companies (GATE Nepal Pvt. Ltd. and Unique Seed Company) requested technical support from CIMMYT to organize field demonstrations of new wheat and lentil varieties for farmers in six strategic districts in the hills and terai (plains) of Nepal. In terai demonstrations were held in Banke, Bardiya, Kailali and Kanchanpur. In hill districts demonstrations were held in Surkhet and Dadeldhura. Altogether, CIMMYT provided support for 60 wheat and lentil field demonstrations during the 2015-2016 winter season in collaboration with national agriculture research system partners.
A team of professionals, which included representatives from District Agriculture Development Offices (DADOs), Nepal Agriculture Research Council (NARC), CSISA-Nepal, seed companies and the media, attended the demonstrations from 13-17 March 2016. They observed three treatments: a farmers’ variety under farmers’ management; an improved variety under farmers’ management and an improved variety under improved management. The visitors also viewed seed production plots, interacted with farmers about key lessons learned and discussed possible strategies for scaling out wheat and lentil technology through public-private partnerships.
During the visit, it was clear that farmers understood the advantages of growing quality seed of recently released wheat varieties such as Vijay, compared to the local varieties. Some farmers asked for wheat varieties with physical features and cooking qualities similar to those of NL 297, an old variety. At one of the participatory variety selection (PVS) plots, senior wheat breeder Madan Bhatta proposed NARC’s pipeline variety BL4341 as an alternative to NL 297. Milan Paudel, GATE Nepal agriculture officer, became keenly interested in BL4341 and said he would collect seed from the trial plot so his company could multiply it.

The team also observed the wheat field of farmer Ram Chandra Yadav, who had planted Vijay on 3 ha using a zero-tillage seed drill. Yadav is also a local service provider of the zero-tillage seed drill promoted by the CSISA project. During the current wheat season, he has provided paid services on 18 hectares (44.5 acres) belonging to other farmers. The team also witnessed the success of new wheat varieties WK 1204, Dhawalagiri and Danphe in the hill district of Surkhet, where farmers planted a significant area with seed saved from their previous harvest.
Lentils were also in focus, most farmers liked the performance of new variety Black Masuro across districts in the terai. Rabendra Sah, senior technical officer of the National Grain Legume Research Program, said that to get higher yields, farmers should sow Black Masuro by 15 October.
DADO officials acknowledged CIMMYT’s contribution to seed system development and mechanization. They proposed an improved model for producing seed of major food crops in public-private partnerships. In this model, seed companies agree to make contractual arrangements with seed producer groups and cooperatives to produce and market truthfully labeled (TL) seed. Once the contract is signed, DADOs will provide source seed to the seed companies at a subsidized rate, and the seed will be multiplied by producer groups and cooperatives. The TL seed thus produced will then be distributed through different food security related projects.
Given that DADOs from Surkhet and Kanchanpur are keen to participate in this model, CIMMYT has agreed to further strengthen such partnership arrangements. There is a growing realization that the CIMMYT can mobilize private seed companies in Nepal to utilize the network of farmer groups and cooperatives to scale out technologies/varieties.
Afghan and Indian researchers are collaborating to combat the wheat rust disease Karnal bunt. Photo: CIMMYT
DELHI, INDIA — Afghanistan is strategically located at the intersection of South, Central and West Asia, making it an incredibly geographically diverse country. Varying climates and terrains across the country have a direct impact on agriculture, including Afghanistan’s staple crop wheat, which is grown in in tropical climates in the east to cooler regions in the west.
However, various rust diseases affect wheat yields across the country. According to the Food and Agricultural Organization of the United Nations, wheat rusts manifest as yellow, blackish or brown colored blisters that form on wheat leaves and stems, full of millions of spores. These spores, similar in appearance to rust, infect the plant tissues, hindering photosynthesis and decreasing the crop’s ability to produce grain.
While yellow rust is one of the most far-reaching diseases in Afghanistan and globally most devastating rust disease, Karnal bunt is another disease that while confined to the eastern part of Afghanistan, has proven challenging to combat with climate change creating more favorable conditions for the disease to spread in the region. In addition, the eastern province of Nangarhar is emerging as an important seed production hub in the country, raising concerns about Karnal bunt.
To counteract and contain Karnal bunt, CIMMYT and the Indian Institute of Wheat and Barley Research (IIWBR) of the Indian Council of Agricultural Research jointly organized a three-day training program on Karnal bunt for Afghan researchers. Indu Sharma, former IIWBR director, stated this training is the beginning of a long collaboration between IIWBR and Afghanistan’s national agricultural research system. She also gave a detailed description of the Karnal bunt pathogen and its epidemiology, emphasizing the importance of detecting and how to combat Karnal bunt in Afghanistan.
During the workshop various principal scientists from IIWBR and the Indian Agricultural Research Institute discussed India’s perspective and experience with wheat diseases, production strategies current research trends and genetic and biotechnological means for improving wheat. There was also a demonstration on preparing Karnal bunt-free seed samples for international shipping by IIWBR principal scientist M. S. Saharan.
In his address, IIWBR Director R. K. Gupta expressed his appreciation for the trainees’ active participation and looked forward to collaborating with them in the future. Sharma cited material exchange and screening of advanced lines for quality and disease resistance as opportunities for future collaboration.

El BATAN, Mexico (CIMMYT) – International scientists are on high alert as they develop tactics to fight a deadly wheat disease that has emerged in Bangladesh, affecting a large portion of the country’s wheat growing area.
Wheat blast, first identified in Brazil in 1985 and widespread throughout South America, deforms grain, causing it to bleach, shrivel and shrink. At its worst, the fast-moving disease can decimate a crop, leading to the urgent need for a multi-pronged approach to fight it.
The recent appearance of the disease, which is caused by the plant fungus pathogen Magnaporthe oryzae, in six districts in southern Bangladesh is estimated to have affected 15 percent of the country’s total wheat growing area of 436,000 hectares (1.08 million acres).
“We need to fight this disease on various fronts – both in the short and long term,” said Etienne Duveiller, principal scientist and wheat pathologist with the International Maize and Wheat Improvement Center (CIMMYT), adding that strategies include preventing the distribution of infected seed, sowing seed at designated optimal times, introducing foliar spray of triazole fungicides and developing disease-resilient seed.
“It’s paramount that infected seeds are identified and that seeds are sown at the best time to avoid rains at the sensitive stage when wheat plants develop the spike where grains form, but we’ve also been working to identify resistant genetic materials – germplasm – for use in developing new varieties, a vital part of the longer term fight against the disease,” he said.
CIMMYT scientists are working with national agriculture programs on this work, setting up germplasm exchanges and testing genotypes in hot spot areas where the disease occurs, Duveiller said, adding that a smallholder farmer in one of the worst-hit areas said he expected to harvest 80 percent less wheat as a result of the disease. The problem compounds over time because farmers keep seed and replant it in subsequent years.
Scientists believe wheat blast spreads by various means, including airborne distribution, from crops planted in rotation with wheat and sexual hybridization.
“We’re not sure what the potential scale of wheat blast spread might be because we’re still trying to understand how it survives from wheat crop to wheat crop, we urgently need investments to understand it,” said Hans Braun, director of CIMMYT’s Global Wheat Program.
“It takes only a few days from the first symptoms occurring until major damage is caused by the fungus,” he added. “This short window makes chemical interventions difficult and prophylactic application of fungicides is too expensive for smallholder farmers. Breeding resistant varieties is the best and possibly the only option to control the disease in the long term.”

NEW DELHI (CIMMYT) — Rice-wheat rotation is practiced by farmers on over 13 million hectares of farmland in South Asia, providing the primary source of food security in the region. However, climate change is projected to have a huge impact and reduce agricultural production 10 to 50 percent by 2050. Complex and local impacts from climate change and other challenges require solutions to risks that can be readily-adapted. Representatives from Bayer Crop Science recently visited the International Maize and Wheat Improvement Center (CIMMYT) offices in India to discuss the potential for developing jointly managed sustainable approaches and technologies to address such challenges.
Sustainable intensification, which involves such conservation agriculture practices as minimal soil disturbance, permanent soil cover and the use of crop rotation to increase profits, protect the environment, maintain and boost yields, is a potential solution that has worked to address the impact of climate change in South Asia. Such practices contribute to improved soil function and quality, which can improve resilience to climate variability.
“Systems research with conservation agriculture practices like direct seeded rice, no-till wheat and recycling crop residues have shown tremendous potential to address the challenges of water and labor scarcity, conserve natural resources and lower the environmental footprint of South Asia’s food bowl,” said M.L. Jat, CIMMYT senior cropping systems agronomist and the South Asia coordinator for the CGIAR Research Program on Climate Change, Agriculture and Food Security, collaboratively managed by the CGIAR consortium of international agricultural researchers.
During the Bayer meeting, challenges and opportunities were identified for direct seeded rice — which requires less labor and tends to mature faster than transplanted crops — and sustainable intensification programs throughout South Asia, particularly in India. Discussions were based on the success of other CIMMYT-Bayer collaborations across South Asia that aim to address agricultural challenges through sustainable intensification — including direct seeded rice — quantifying mitigation potential of conservation agriculture-based management in rice-wheat rotation and smart farm mechanization to make farm management more efficient and productive.
Moving forward, CIMMYT and Bayer will focus on agricultural systems research to ensure even more effective interventions with higher yields, collaborate to develop new sustainable technology and increase uptake throughout the region. Sustainable intensification practices are expected to continue to grow in the region thanks to these and other collaborations, along with the advent of technological advancements and increased adoption.

Bayer representatives at the meeting included: Hartmut van Lengerich, head of cereals and fungicides; Juergen Echle, global segment manager of rice herbicides; Christian Zupanc, global segment manager of rice fungicides; Mahesh Girdhar, global crop manager of rice and Rajvir Rathi, vice president of public and government affairs. CIMMYT representatives included: Tek Sapkota, mitigation specialist; Balwinder Singh, crop modeling specialist and Alwin Keil, senior economist.

SINDHULPALCHOWK, Nepal (BGRI) — Farming the terraced hillsides above the Indrawati River Valley of Nepal, Nabaraj Sapkota and his wife Muthu Dei experience the impacts of climate change on an almost daily basis. Erratic rains make planting difficult. Warm, misty conditions and prolonged winter temperatures increase the incidence of wheat rusts that reduce yield. Unpredictable hailstorms flatten wheat and rice before they can be harvested.
“When we need rain, there is no rain. And when we don’t need rain, there is plenty of rain,” says Nabaraj. “We used to only have rain from May through July, now we have rain and mist from November.”
Khim lal Bastola grows wheat, maize and rice in rotation and sustains four generations in his 12-person household near Pokhara. “The change is obvious: man produces something with his hard labor but strong winds and hailstorms destroy it,” he said.
“The climate change scenario for Nepal — where temperature are likely to increase and precipitation is likely to be more erratic — will disproportionally affect smallholder farmers,” said Dhruba Thapa, a senior scientist with the Nepal Agricultural Research Council. “For Nepal, the cost of not adapting to climate change will be high.”
Like many farmers in Nepal, Bastola and the Sapkotas need technical assistance to help them adapt to climate change. They eagerly soak up the education offered by people like Thapa, Sarala Sharma, and Sunita Adhibari, NARC scientists who distribute disease resistant varieties of wheat and help farmers learn to identify diseases.
Scientists and farmers also soak up training from the Borlaug Global Rust Initiative (BGRI), and specialists like Dave Hodson, a wheat surveillance specialist with CIMMYT, who shows them how to scout for wheat rust and upload data into the global RustTracker monitoring system.
FARMING PERVASIVE BUT DIFFICULT IN NEPAL
Farming in Nepal is hard, backbreaking labor predominantly done by hand in fields rarely more than one-quarter of an acre in size. Men plow the small plots on the terraced hillsides with oxen. Women break up the clods with heavy adzes. Although rarely above subsistence level, small farms are of vital importance in sustaining the multi-generational communities scattered throughout the Himalayas in the high hills to the north, the temperate mid-hills, and the subtropical terai to the south.
The livelihoods of more than 75 percent of the people in Nepal are based on agriculture and forestry, and almost 65 percent of the agriculture is rainfed, Nepal is among the 25 nations in the world with the lowest GDP per person and also ranks among the 25 with the greatest decrease in forested land. Rural populations are heavily clustered in river basins whose annual monsoon-fed flood cycles are likely to be exacerbated by warming. Deforestation adds to the problem, intensifying flooding and contributing to the likelihood of landslides.
HELPING FARMERS ADAPT TO CLIMATE CHANGE
Using disease resistant and improved seeds, and adopting different planting and harvesting calendars helps farmers adapt to climate change.
In Chhampi, north of Kathmandu, Krishna Bahadur Ghimire and the local farmers’ cooperative of which he is president, are now producing improved rice, wheat and maize on 140 ropanis of land. Ghimere supplies beans, rice, eggplant, soybeans, wheat and vegetable seeds to his neighbors. He started farming on one ropani of land (~ 500 sq.m) in 1997 but switched to the seed business when he found himself having to drive two hours to Kathmandu to get the improved varieties he needed.
“Our local varieties were not climate smart. We went to Kathmandu to get improved seeds from the Nepalese Agricultural Research Center because their seeds are more disease resistant, higher yielding, and higher quality,” said Ghimire, who has worked with Thapa for 11 years. “New varieties are less lodging and scattering during storms and high winds than the local ones.”
“Farmers need climate smart crops that have been improved for yield and disease resistance, but they also need seeds adapted for variable weather conditions whether we have drought or excess rainfall,” said Thapa. “NARC screens many lines and then provides seeds of promising lines to farmers for participatory variety selection trials, like with Ghimire’s group.”
Naparaj, the Sindhulpalchowk farmer, initially received 300 grams of seven varieties of improved wheat from Thapa. “I was thinking how I could uplift them (my neighbors),” said Naparaj. “I thought to myself, the lives of these people must be uplifted through improved seeds which would give them good production. We used to get one muri (~3.5 liters or 70 kg) of wheat per one ropani (~ 500 sq.m.). Now we are threshing three or four times more. It is a huge profit.”
Ghimere’s 25-year-old nephew Saroj Kumar Bista, speaks of another problem affecting farmers that requires gender-sensitive initiatves. “Many young men are going to the Middle East to work and not moving into the farming sector,” he said.
Nowhere is this more evident than in Godhavari, where Manju Khavas, Radha Basnet and Janaki Silwal’s sons have gone to the Middle East or Japan to work. Their husbands work off the farm, leaving them in charge. “At first we were overwhelmed,” said the 52-year-old Khavas. “We could not find someone to dig the fields. Now it is easier because of the handheld tractor.”
Thapa introduced improved eight or nine varieties of wheat to their community as well as agronomic practices like planting in rows, incorporating manure for fertilizer, and using handheld tractors (similar to heavy duty rototillers).
How does Khavas count improvement? “When we were 7 or 8 members in the family, the produce of this land was not enough. Now the produce is enough for 13 to 14 people,” she said. Wheat yields are so improved that she and her friends want a wheat threshing machine so they don’t have to thresh the greater quantities by hand.
Although the women said they have yet to “evaluate” climate change, they noted the “environment has been spoilt.”
“During the harvesting season of the wheat, we suffer from the fear of rain,” said Khavas. “Hailstorms also scare us. The moment the wheat becomes yellow, we begin to feel afraid whether we will be able to harvest it or not. And then when the wheat is harvested amid the fear of rain, in the paddy rice planting time, there is no rain.”
MORE TRAINING FOR CLIMATE CHANGE ADAPTATION
Dave Hodson, a surveillance expert with CIMMYT and the BGRI, travels to countries like Nepal to train scientists on using handheld tablets to scout for disease and input data into global disease tracking and monitoring systems that can help to predict disease outbreaks.
Since 2008, the BGRI has held five 2-week training sessions on the “Art and Science of Rust Pathology and Wheat Breeding” in Asia for scientists in the South Asian Association for Regional Cooperation (SAARC), including scientists from Nepal, India, Pakistan, Afghanistan, Bangladesh and Bhutan. The course is slated to be on-line this summer.
Nepalese farmers lack understanding of meteorological data and how to reduce risks in agriculture and farming. Sushila Pyakurel, who works with ICDO Lalitpur, has helped initiate Climate Field Schools in Nepal where farmers learn the effects of climate change, identifying crops most suitable to grow, seed selection, scheduling farm operations/farm management practices, and adaptation strategies/methodologies.
One of the new areas of expansion for the BGRI is the new Delivering Genetic Gain in Wheat project, a $24M effort funded by the Bill & Melinda Gates Foundation to make wheat for smallholder farmers around the world more heat tolerant and disease resistant in the face of climate change. It builds on the successes of the 2008-2015 Durable Rust Resistance in Wheat project, which initiated and funded the SAARC training courses.
DEDICATION: April 25, 2016: For smallholder farmers in Nepal, the challenges of climate change are disastrous enough. A 7.8 magnitude earthquake devastated Nepal on 25 April 2015, less than one month after the Borlaug Global Rust Initiative team visited. More than 9,000 people died and almost 900,000 homes were destroyed. Some of the hardest hit areas were Sindhulpalchowk and Chhampi. This Earth Day blog is dedicated to the resilient farmers of Nepal. It is the BGRI’s sincerest hope that their families are well on their way to recovery.

ISLAMABAD– The United States Agency for International Development (USAID)-funded Agricultural Innovation Program for Pakistan shared the findings and proposed a plan for applying information communication technology (ICT) in agricultural extension in Pakistan, today in Islamabad during the launch ceremony of a working paper on the use of ICT in agriculture extension in Pakistan
This working paper is a product of AIP’s e-PakAG led by the University of California Davis (UC Davis) and highlights a series of opportunities to enhance the use of ICT in agricultural extension. Held at the National Agricultural Research Center (NARC), Islamabad, the launch ceremony of ICT use highlighted the promising role of new tools such as cell phones and enhanced videos in obtaining better scientific results to help farmers. The work by UC Davis and the University of Agriculture, Faisalabad, was implemented as part of the AIP, led by the International Maize and Wheat Improvement Center (CIMMYT) in partnership with the Pakistan Agricultural Research Council (PARC), ILRI, AVRDC, IRRI and UC Davis.

CIMMYT Country Representative Imtiaz, Muhammad during the presentation of a working paper on ICT in agricultural extension said, “This new era of technology is leading to new horizons in agricultural research. The trends indicate powerful impact of information communication technology on improving the farmer’s productivity and these innovative practices will ultimately improve the Pakistani agricultural sector.”
Praising the efforts of AIP, Federal Secretary for National Food Security and Research Abid Javed pointed out that the continuous support of the American people is reshaping Pakistan’s agricultural sector, particularly farmers.
“ICT, like never before, offers us unprecedented opportunities to connect people and make useful information available to poor farmers. We have to find out how to better turn that potential into reality,” said Mark Bell, leader of AIP’s e-Pak Ag.

As PARC Chairman Nadeem Amjad indicated, today the use of ICT is essential and AIP’s efforts will make it easy to convey relevant and credible information to extension staff and, through them, to farmers.
The United States is committed to working hand in hand with Pakistan to develop and modernize the agricultural sector. As a global center of excellence in the improvement of maize and wheat systems, CIMMYT has maintained a long and highly productive relationship with the Pakistani government and national partners, with the invaluable support of U.S. government agencies. AIP’s E-Pak Ag activities are capturing science and research innovations led by UC Davis, which has a rich history of working with and strengthening research, education and extension programs around the world.
Launched in 2013, the USAID-funded Agricultural Innovation Program for Pakistan (AIP) works to increase agricultural productivity and incomes by promoting and disseminating modern practices in the cereal and cereal systems (wheat, maize and rice), livestock, fruit, and vegetable sectors; enhancing the capacity of agricultural scientists and researchers through short-term and long-term training such as M.Sc. and Ph.D. scholarships at U.S. land grant universities; establishing Provincial Agricultural Research for Development (AR4D) Boards to support expansion of provincial linkages to national, regional and international communities through a mechanism of coordination; and improving agricultural growth and research in Pakistan through a Competitive Grants System. Project management is vested in a unique consortium of Consultative Group for International Agricultural Research (CGIAR) centers, US land grant universities, non-CGIAR centers, and the Pakistan Agricultural Research Council (PARC), led by the International Maize and Wheat Improvement Center (CIMMYT).

ISLAMABAD – The maize sector in Pakistan is benefiting from an upsurge in investments leading to new varieties from the International Maize and Wheat Improvement Center (CIMMYT) that have the potential to increase production, enhance nutrition and strengthen national industry.
Maize is the third most important cereal crop in Pakistan, which at a production rate of four tons per hectare, has one of the highest national yields in South Asia. Maize productivity in Pakistan has increased almost 75 percent from levels in the early 1990s due to the adoption and expansion of hybrid maize varieties. The crop is cultivated both in spring and autumn seasons and grows in all provinces throughout the country.
However, the lack of a strong national seed system has caused Pakistan to import more than 85 percent of its hybrid maize seed at a cost averaged about $50 million annually since 2011. When coupled with other factors including a limited source of seed providers and non-relaxation of duties on imported seed, this causes the unit price of hybrid maize seed to be the most expensive in South Asia.
PROJECT BOOSTS SEED
A project launched in 2013, CIMMYT’s Agricultural Innovation Program (AIP) funded by the U.S. Agency for International Development (USAID), led to a large-scale evaluation of maize varieties, which have since resulted in more than 1,000 diverse genotypes tested for favorable traits across Pakistan. Currently, 20 public- and private-sector companies are partnering with CIMMYT to test new varieties and deploy locally-adapted products.

In just two years since the launch of this initiative, more than 80 CIMMYT-derived hybrids and open pollinated varieties of maize have been identified and adapted to diverse ecologies in Pakistan. In the first phase, CIMMYT allocated 49 maize products for registration, commercial release, further seed scale-up and delivery in the target geographies in Pakistan. This maize germplasm was sourced from CIMMYT’s regional maize breeding hubs mainly from Colombia, Mexico and Zimbabwe. With the help of national partners, these improved varieties are being put in the hands smallholder farmers throughout the country.
Seed businesses in Pakistan now have the leverage to run a competitive domestic market for maize seed, thanks to these new varieties. Diverse new lines are also more nutritious, mature earlier and are more tolerant to drought. They can also be delivered at an affordable price which is a huge step forward compared to the limited options smallholder farmers had before AIP started.
Biofortification, or the enhancement of the nutritional value of a crop, has been a cornerstone of CIMMYT’s work in developing improved varieties. Quality Protein Maize (QPM) was the first new hybrid product to reach farmers in Pakistan. Demonstration seeds from the first two biofortified maize hybrids in Pakistan were officially distributed to farmers this February by the National Agricultural Research Center (NARC), one of the national partners to AIP. The two QPM hybrids, originally from CIMMYT-Colombia, will reach about 300 farmers this season and further distribution is expected by 2017.

“We know how precious (CIMMYT’s) parental seeds are,” said Muhammad Hashim Popalzai from Pakistan’s Ministry of National Food Secuirity and Research. “At times it will take up to eight years to develop inbred lines and another 3-4 years to constitute hybrid seeds, however, we are getting them easily under the AIP program.”
Although developing new seeds takes time, the benefits could make a huge contribution to Pakistan’s economy, health and livelihoods for farmers across the country.
“These parental seeds will help us to produce the seed locally,” said Faiysal Hayat, deputy manager of seed company Jullundur Private Ltd., adding that they will also “enable us to provide quality seed at an affordable price to farmers.”
In reviewing the progress of AIP maize activities, Abdu Rahman Beshir, CIMMYT’s maize improvement and seed systems specialist said: “The overwhelming interest and collaborations from public-private stakeholders of Pakistan’s maize sector are the main thrust for CIMMYT’s maize varietal deployment drive in Pakistan.”
Subsequent activities in quality seed production and enhanced product positioning will further reinforce the encouraging gains of AIP which aims to have a vibrant maize seed system in Pakistan, according to Beshir.
NEW DELHI (CIMMYT) — Ram Kanwar Malik, senior agronomist at the International Maize and Wheat Improvement Center (CIMMYT), has received the 2015 Derek Tribe Award from the Crawford Fund, for his “outstanding contributions to making a food secure world by improving and sustaining the productivity of the rice-wheat system of the northwestern and eastern Indo-Gangetic Plains.”
The award recognizes Malik’s more than 30 years of work in agricultural research and development dedicated to improving the livelihoods of millions of small and marginal farmers in India. He led the development of a management solution for herbicide resistant Phalaris minor, a major wheat weed. This pioneering research is estimated to have prevented farmers from losing nearly 1 million hectares (2.5 million acres) of wheat and to have raised wheat productivity in the grain basket states of Haryana and Punjab, between 1992 and 2000.
“For developing countries like India where farmers are smallholders and marginalized and investment in research is low, the development of new technologies and the process of delivery are inseparable,” said Malik, highlighting his life-long passion for understanding the need for farmer participation in research. “In fact, a top-down approach could put up barriers to the adoption of new technologies. Listening to farmers and tailoring technologies to serve their needs thus become paramount.”
Malik’s collaborative work with national and international partners and farmer participatory approaches has also led to achievements in the adoption and spread of climate-resilient technologies such as zero-tillage, laser land leveling and direct-seeded rice, as well as policy changes at the government level.
Recently, Malik played an instrumental role in advocating for the early sowing of wheat in Bihar, which can double a farmer’s yield and avoid crop failure caused by higher temperatures and an early summer. Malik’s team has created a network of more than 2,000 service providers to provide easy access for smallholder farmers to machinery and modern farming technologies.
