CIMMYT 2016 annual report ‘Maize and wheat for future climates’

The 2016 CIMMYT Annual Report details the strong partnerships and science through which CIMMYT creates and shares innovations for farmers to grow more, earn more and reduce environmental impacts, now and in the future. Highlights include:

  • Maize and wheat breeding speeds up to equip farmers with varieties for dryer, hotter climates, and to resist evolving pathogens and pests.
  • Scientists refute trendy claims disparaging wheat and promote the nutritional benefits of this vital food grain.
  • Growing partnerships, including the joint launch with Henan Agricultural University, China, of a new maize and wheat research center.
  • Dramatically expanded maize seed markets for Mexican farmers.
  • Use of zero tillage and other sustainable agriculture practices in southern Africa and South Asia.

In 2016, CIMMYT marked and celebrated 50 years of applying excellence in maize and wheat science to improve the livelihoods of the disadvantaged. With the commitment and continuous support of dedicated staff, partners and donors, the Center will continue contributing to a food- and nutrition-secure future for all.

Advice for India’s rice-wheat farmers: Put aside the plow and save straw to fight pollution

By Mike Listman/CIMMYT

The Turbo Happy Seeder allows farmers to sow a rotation crop directly into the residues of a previous crop—in this case, wheat seed into rice straw—without plowing, a practice that raises yields, saves costs and promotes healthier soil and cleaner air.

EL BATAN, Mexico (November 28,2016) – Recent media reports show that the 19 million inhabitants of New Delhi are under siege from a noxious haze generated by traffic, industries, cooking fires and the burning of over 30 million tons of rice straw on farms in the neighboring states of Haryana and Punjab.

However, farmers who rotate wheat and rice crops in their fields and deploy a sustainable agricultural technique known as “zero tillage” can make a significant contribution to reducing smog in India’s capital, helping urban dwellers breathe more easily.

Since the 1990s, scientists at the International Maize and Wheat Improvement Center (CIMMYT) have been working with national partners and advanced research institutes in India to test and promote reduced tillage which allows rice-wheat farmers of South Asia to save money, better steward their soil and water resources, cut greenhouse gas emissions and stop the burning of crop residues.

The key innovation involves sowing wheat seed directly into untilled soil and rice residues in a single tractor pass, a method known as zero tillage. Originally deemed foolish by many farmers and researchers, the practice or its adaptations slowly caught on and by 2008 were being used to sow wheat by farmers on some 1.8 million hectares in India.

Available Now: The 2015 WHEAT Annual Report

By Katie Lutz/CIMMYT

EL BATAN, Mexico (August 24,2016)- High returns to global wheat research Building on more than a half-century of proven impacts, the global wheat improvement system led by CGIAR centers continues to be the chief source for wheat farmers in Africa, Asia and Latin America of critical traits such as high yields, disease resistance and enhanced nutrition and quality.

A recently-published study found that CGIAR-derived varieties – nearly all traceable to CIMMYT and ICARDA breeding programs – cover more than 100 million of 220 million hectares worldwide and bring economic benefits of as much as $3.1 billion each year. To achieve impacts in wheat agri-food systems, CIMMYT and ICARDA depend on national partnerships in over 100 countries and critical support from CGIAR Fund Donors and other contributors, whom we sincerely thank on behalf of the world’s wheat farmers and consumers.

NAAS fellow M.L. Jat talks about climate change, sustainable agriculture

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 .

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.

CSISA Aids Female Farmers in India

Female farmers in India are not only responsible for managing the farm work and household chores, but have increasingly become a part of the sowing, weeding and harvesting of crops. The Cereal Systems for South Asia (CSISA) project is working with female farmers in Bihar to ensure that women are learning and developing new skills and getting information on improved farming technologies and practices.

In 2014, more than 100 female farmers in Muzaffarpur district planted their wheat using zero tillage technology. Watch the video above to learn more about the initiatives implemented by CSISA in India.
