EL BATAN, Mexico (December 18,2016)- CIMMYT senior scientist M.L. Jat has received India’s National Academy of Agricultural Sciences (NAAS) fellowship in Natural Resource Management for his “outstanding contributions in developing and scaling” conservation agriculture-based management technologies for predominant cereal-based cropping systems in South Asia.

Jat’s research on conservation agriculture (CA) – sustainable and profitable agriculture that improves livelihoods of farmers via minimal soil disturbance, permanent soil cover, and crop rotations – has guided improvements in soil and environmental health throughout South Asia. His work has led to policy-level impacts in implementing CA practices such as precision land leveling, zero tillage, direct seeding, and crop residue management, and he has played a key role in building the capacity of CA stakeholders throughout the region.

Sustainable innovation, including climate-smart agriculture, were a major theme at the COP21 climate talks .

Call for Applications for Basic Wheat Improvement Course

By Katie Lutz/CIMMYT

EL BATAN, Mexico (November 25, 2015) – Applications for the Basic Wheat Improvement Course (BWIC) are due 15 December.

The BWIC is a three-month intensive program at the Campo Experimental Norman E. Borlaug (CENEB) in Ciudad Obregon, Sonora, that targets young and mid-career scientists, focusing on applied breeding techniques in the field.

The training program has benefited national research programs since its inception. The increasing number of wheat scientists in major wheat producing countries reflects the great need and interest of national programs in training young scientists. One of the most frequent requests from countries and national programs is for more trained scientists.

Fast-tracking wheat seed deployment in remote Pakistan regions

By Mike Listman/CIMMYT

ISLAMABAD, Pakistan (November 19,2015)-Nearly 10,000 smallholder farmers in marginal, far-flung areas of Pakistan are harvesting more, eating better, and earning cash from their wheat crops, as a result of a partnership that is working to offer widespread access to improved wheat seed and farming practices.

“The extra grain from the new varieties will be enough for my family for three additional months,” said farmer Khan Said of Swat, Khyber Pakhtunkhwa, Pakistan, as he surveyed his tawny, sun-kissed wheat field. He also hoped the extra straw from his crop would earn him about US $140.

In autumn-2014, participating farmers in 63 moderately-to-highly-food-insecure districts received a 25-kilogram bag of seed of the new varieties—enough to sow a quarter hectare and compare their performance with that of traditional varieties, as well as helping to grow more seed for redistribution. The new varieties are high-yielding and resist wheat rust, a fungal disease whose three forms—stem, leaf, and yellow rust—are found on as much as half of Pakistan’s wheat area and which constitute a rising threat to the crop.

“Our results show a yield advantage of more than 100% in harsh environments for the new varieties and, after just one season, farmers are attesting to significant improvements in their food security and livelihoods,” said Krishna Dev Joshi, CIMMYT wheat improvement specialist who is coordinating the contributions of 27 partners with this aim. “This proves how, with better access to seed of new varieties and technical support, Pakistani farmers can benefit from the latest wheat science and replace older, rust-susceptible varieties.”

According to Joshi, if half of the harvest from the new varieties were saved as seed, this could be sown on at least 30,000 hectares, producing enough additional seed to cover 1 million hectares in the third year with no extra costs, through farmer-to-farmer seed flow networks, and ultimately creating visible impacts in the project area. The follow-up surveys indicated an overwhelming acceptance of new wheat varieties, as over 87% of participating farmers saved their seeds to expand area under the varieties.

Clone of magic wheat disease-resistance gene sheds light on new defense mechanism

losses and reducing the need for farmers to use costly fungicides, once the gene is bred into high-yielding varieties.

A global research team isolated the wheat gene Lr67, revealing how it hampers fungal pathogen growth through a novel mechanism.

The study, which was published in Nature Genetics on 9 November, involved scientists from the International Maize and Wheat Improvement Center (CIMMYT), the Chinese Academy of Agricultural Sciences (CAAS), Mexico’s National Institute of Forestry, Agriculture, and Livestock Research (INIFAP), the Norwegian University of Life Sciences and scientists from Australia, including the Commonwealth Scientific and Industrial Research Organisation (CSIRO), the University of Newcastle, and the University of Sydney.

According to Ravi Singh, CIMMYT distinguished scientist, wheat breeder, and co-author of the new study, Lr67 belongs to a group of three currently-known “magic” genes that help wheat to resist all three wheat rusts and powdery mildew, a disease that attacks wheat in humid temperate regions. The genes act in different ways but all slow — rather than totally stopping — disease development. When combined with other such partial resistance genes through breeding, they provide a strong, longer-lasting protection for plants, boosting food security.

NAIROBI, Kenya (October 8, 2015)- Plant pathologist Ruth Wanyera and wheat breeders Godwin Macharia and Peter Njau of the Kenya Agriculture and Livestock Research Organization (KALRO) received the 2015 Gene Stewardship Award at the Borlaug Global Rust Initiative Workshop (BGRI) in Sydney, Australia.

“The KALRO team has done an outstanding job – their work has had significant global impact by accelerating the capacity of developing countries to protect themselves against this swift-moving and devastating disease,” said Sridhar Bhavani, a wheat breeder who leads the International Maize and Wheat Improvement Center (CIMMYT) stem-rust screening nurseries in East Africa and nominated the team for the award.

Zero-till Wheat Raises Farmers’ Incomes in Eastern India, Research Shows

By Anuradha Dhar/CIMMYT

NEW DEHLI, India (September 30, 2015)- Large-scale adoption of zero tillage wheat production could play a major role in making the eastern Indian state of Bihar self-sufficient in wheat, according to a new study published by CIMMYT agricultural scientists.Farmer with wheat harvest (2)

In a study published last month in Food Security, CIMMYT researchers reported that wheat farmer’s total annual income increased by 6% on average with the introduction of zero tillage (ZT) in Bihar. While studies done in the past in the eastern Indo-Gangetic Plains (IGP) have shown ZT impacts in field trials or controlled environments, this research is believed to be the first that studied actual impacts in farmers’ fields.

ZT allows direct planting of wheat without plowing, sowing seeds directly into residues of the previous crop on the soil surface, thus saving irrigation water, increasing soil organic matter and suppressing weeds.

“We found that the prevailing ZT practice, without full residue retention, used by farmers in Bihar has led to an average yield gain of 498 kilogram per hectare (19%) over conventional tillage wheat, which is in contrast to the results of a recent global meta-analysis” says Alwin Keil, Senior Agricultural Economist, CIMMYT and the lead author of this study.

The global meta-analysis published last year compared crop yields in ZT and conventionally tilled production systems across 48 crops in 63 countries. It reported that ZT is only profitable in rainfed systems and when it is combined with full residue retention and crop rotation. “However, in Bihar, marginal and resource-poor farmers cannot afford to leave the full residue in the field as they use the rice straw to feed their livestock,” says Keil.
