Fifty delegates from across the globe recently gathered at the 7th International Cereal Nematode Symposium in New Delhi, India to discuss the spread of cereal nematodes, strategies to lessen their impact on crops and ways to boost international collaboration on research.

Nematodes, microscopic plant parasites that include the Heterodera species of cereal cyst nematode and the Pratylenchus species of root lesion nematodes, are widespread in wheat production systems throughout West Asia, North Africa, parts of Central Asia, northern India, and China, and pose a grave economic problem for wheat production systems globally.

The International Maize and Wheat Improvement Center (CIMMYT) and the Turkish Ministry of Agriculture and Forestry have been working over the last 12 years —  in collaboration with the International Center for Agriculture in the Dry Areas (ICARDA), national program partners, and research institutions in Australia and Europe – to understand the importance and distribution of these species of cereal nematodes, as part of the ICARDA-CIMMYT Wheat Improvement Program (ICWIP).  

“Because cereals are the staple food for the majority of the world’s population, cereal nematodes pose an enormous threat to global food security,” said Abdelfattah Dababat, leader of CIMMYT’s Soil Borne Pathogens Program.

“The symposium allows scientists from around the world to share their findings, lessons and strategies to combat this threat.”

The symposium, organized by ICWIP and hosted by the Division of Nematology at the ICAR- Indian Agricultural Research Institute (IARI), was held November 3-6 at New Delhi’s National Agricultural Science Complex. The conference was inaugurated by Dr. Trilochan Mohapatra, Director General of ICAR & Secretary DARE, Government of India. It included sessions on the global status and distribution of cereal nematodes, their economic importance and population dynamics, management strategies both with and without using host resistance, the genomes and parasitism genes of cereal nematodes, and the use of molecular tools for cereal nematode research.

Among the notable global developments shared, highlights included the following.

  • Scientists from Turkey, Syria, Iran and Israel described the distribution and management status of Heterodera spp. in their region.
  • Hendrika Fourie from South Africa’s North West University, and colleagues, discussed the nematode problems in South Africa.
  • Rebecca Zwart and Grant Hollaway, from the University of Southern Queensland, Australia, presented findings on the Pratylenchus menace in wheat in Australia.
  • Uma Rao, a co-organizer of the symposium from IARI, and colleagues, discussed the deployment of molecular tools to manage the problem of the Meloidogyne graminicola nematode in rice-wheat cropping systems.   
  • Richard Sikora, from the University of Bonn, Germany, summarized the current challenges in nematology, especially pertaining to wheat and maize, and reiterated the need for new technologies and management approaches for the small- and medium-sized farms of the future. He also highlighted the role of remote sensing in detecting nematode diseases.
  • A.K. Singh, Joint Director of Research at IARI gave a formal presentation on molecular breeding of Basmati rice.

Trilochan Mohapatra, Director General of ICAR & Secretary Dare, and Arun K. Joshi from CIMMYT’s India office were among the other distinguished speakers. 

Following the symposium, participants observed nematode-related research work underway at IARI’s Division of Nematology, the largest nematology center in India. They also visited the IARI museum and the institute’s Division of Entomology.

Symposium supporters include CIMMYT, the CGIAR Research Program On Wheat, the Indian Council of Agricultural Research (ICAR), the Borlaug Institute for South Asia (BISA), the Indian Agricultural Research Institute (IARI), the Republic of Turkey’s Ministry of Food, Agriculture and Livestock, Corteva, Syngenta, and the Plant Breeders Union of Turkey (BISAB). Previous symposiums have been held in Turkey, Austria, China and Morocco.

Data from microsatellites can be used to detect and double the impact of sustainable interventions in agriculture at large scales, according to a new study led by the University of Michigan (U-M).

By being able to detect the impact and target interventions to locations where they will lead to the greatest increase or yield gains, satellite data can help increase food production in a low-cost and sustainable way.

According to the team of researchers from U-M, the International Maize and Wheat Improvement Center (CIMMYT), and Stanford and Cornell universities, finding low cost ways to increase food production is critical given that feeding a growing population and increasing the yields of crops in a changing climate are some of the greatest challenges of the coming decades.

“Being able to use microsatellite data, to precisely target an intervention to the fields that would benefit the most at large scales will help us increase the efficacy of agricultural interventions,” said lead author Meha Jain, assistant professor at the U-M School for Environment and Sustainability.

Microsatellites are small, inexpensive, low-orbiting satellites that typically weigh 100 kilograms (220 pounds) or less.

“About 60-70% of total world food production comes from smallholders, and they have the largest field-level yield gaps,” said Balwinder Singh, senior researcher at CIMMYT.

To show that the low-cost microsatellite imagery can quantify and enhance yield gains, the researchers conducted their study in smallholder wheat fields in the Eastern Indo-Gangetic Plains in India.

They ran an experiment on 127 farms using a split-plot design over multiple years. In one half of the field, the farmers applied nitrogen fertilizer using hand broadcasting, the typical fertilizer spreading method in this region. In the other half of the field, the farmers applied fertilizer using a new and low-cost fertilizer spreader.

To measure the impact of the intervention, the researchers then collected the crop-cut measures of yield, where the crop is harvested and weighed in field, often considered the gold standard for measuring crop yields. They also mapped field and regional yields using microsatellite and Landsat satellite data.

They found that without any increase in input, the spreader resulted in 4.5% yield gain across all fields, sites and years, closing about one-third of the existing yield gap. They also found that if they used microsatellite data to target the lowest yielding fields, they were able to double yield gains for the same intervention cost and effort.

“Being able to bring solutions to the farmers that will benefit most from them can greatly increase uptake and impact,” said David Lobell, professor of earth system science at Stanford University. “Too often, we’ve relied on blanket recommendations that only make sense for a small fraction of farmers. Hopefully, this study will generate more interest and investment in matching farmers to technologies that best suit their needs.”

The study also shows that the average profit from the gains was more than the amount of the spreader and 100% of the farmers were willing to pay for the technology again.

Jain said that many researchers are working on finding ways to close yield gaps and increase the production of low-yielding regions.

“A tool like satellite data that is scalable and low cost and can be applied across regions to map and increase yields of crops at large scale,” she said.

Alternatives to burning can increase Indian farmers’ profits and cut pollution, new study shows

Published in Science, the article provides evidence for national policies that block stubble burning and promote no-till mechanization to manage crop residues.

The new study compares the costs and benefits of 10 distinct land preparation and sowing practices for northern India’s rice-wheat cropping rotations, which are spread across more than 4 million hectares. The direct seeding of wheat into unplowed soil and shredded rice residues was the best option — it raises farmers’ profits through higher yields and savings in labor, fuel, and machinery costs.

The study, conducted by a global team of eminent agriculture and environmental scientists, was led by researchers from The Nature Conservancy, the International Maize and Wheat Improvement Center (CIMMYT), the Indian Council of Agricultural Research (ICAR), the Borlaug Institute for South Asia (BISA) and the University of Minnesota.

A new economic study in the journal Science shows that thousands of farmers in northern India could increase their profits if they stop burning their rice straw and adopt no-till practices to grow wheat. Alternative farming practices could also cut farmers’ greenhouse gas emissions from on-farm activities by as much as 78% and help lower air pollution in cities like New Delhi.

A burning issue

To quickly and cheaply clear their fields to sow wheat each year, farmers in northern India burn an estimated 23 million tons of straw from their rice harvests. That enormous mass of straw, if packed into 20-kilogram 38-centimeter-high bales and piled on top of each other, would reach a height of over 430,000 kilometers — about 1.1 times the distance to the moon.

Regulations are in place in India to reduce agricultural fires but burning continues because of implementation challenges and lack of clarity about the profitability of alternate, no-burn farming.

Farmers have alternatives, the study shows. To sow wheat directly without plowing or burning rice straw, farmers need to purchase or rent a tractor-mounted implement known as the “Happy Seeder,” as well as attach straw shredders to their rice harvesters. Leaving straw on the soil as a mulch helps capture and retain moisture and also improves soil quality, according to M.L. Jat, CIMMYT Principal Scientist, cropping systems specialist and a co-author of the study.

Win-win

The Science study demonstrates that it is possible to reduce air pollution and greenhouse gas emissions in a way that is profitable to farmers and scalable.

The paper shows that Happy Seeder-based systems are on average 10%–20% more profitable than straw burning options.

“Our study dovetails with 2018 policies put in place by the government of India to stop farmers from burning, which includes a US$166 million subsidy to promote mechanization to manage crop residues within fields,” said Priya Shyamsundar, Lead Economist, Global Science, of The Nature Conservancy and first author of the study.

Shyamsundar noted that relatively few Indian farmers currently sow their wheat using the Happy Seeder but manufacturing of the Seeder had increased in recent years. “Less than a quarter of the total subsidy would pay for widespread adoption of the Happy Seeder, if aided by government and NGO support to build farmer awareness and impede burning.”

“With a rising population of 1.6 billion people, South Asia hosts 40% of the world’s poor and malnourished on just 2.4% of its land,” said Jat, who recently received India’s prestigious Rafi Ahmed Kidwai Award for outstanding and impact-oriented research contributions in natural resource management and agricultural engineering. “Better practices can help farmers adapt to warmer winters and extreme, erratic weather events such as droughts and floods, which are having a terrible impact on agriculture and livelihoods. In addition, India’s efforts to transition to more sustainable, less polluting farming practices can provide lessons for other countries facing similar risks and challenges.”

In November 2017, more than 4,000 schools closed in Delhi due to seasonal smog. This smog increases during October and November when fields are burned. It causes major transportation disruptions and poses health risks across northern India, including Delhi, a city of more than 18 million people.

Some of these problems can be resolved by the use of direct sowing technologies in northwestern India.

“Within one year of our dedicated action using about US$75 million under the Central Sector Scheme on ‘Promotion of agriculture mechanization for in-situ management of crop residue in the states of Punjab, Haryana, Uttar Pradesh and NCT of Delhi,’ we could reach 0.8 million hectares of adoption of Happy Seeder/zero tillage technology in the northwestern states of India,” said Trilochan Mohapatra, director general of the Indian Council of Agricultural Research (ICAR). “Considering the findings of the Science article as well as reports from thousands of participatory validation trials, our efforts have resulted in an additional direct farmer benefit of US$131 million, compared to a burning option,” explained Mohapatra, who is also secretary of India’s Department of Agricultural Research and Education.

Innovative irrigation promises “more crop per drop” for India’s water-stressed cereals

On World Water day, researchers show how India’s farmers can beat water shortages and grow rice and wheat with 40 percent less water

India’s northwest region is the most important production area for two staple cereals: rice and wheat. But a growing population and demand for food, inefficient flood-based irrigation, and climate change are putting enormous stress on the region’s groundwater supplies. Science has now confronted this challenge: a “breakthrough” study demonstrates how rice and wheat can be grown using 40 percent less water, through an innovative combination of existing irrigation and cropping techniques. The study’s authors, from the International Maize and Wheat Improvement Center (CIMMYT), the Borlaug Institute for South Asia (BISA), Punjab Agricultural University and Thapar University, claim farmers can grow similar or better yields than conventional growing methods, and still make a profit.

The researchers tested a range of existing solutions to determine the optimal mix of approaches that will help farmers save water and money. They found that rice and wheat grown using a “sub-surface drip fertigation system” combined with conservation agriculture approaches used at least 40 percent less water and needed 20 percent less Nitrogen-based fertilizer, for the same amount of yields under flood irrigation, and still be cost-effective for farmers. Sub-surface drip fertigation systems involve belowground pipes that deliver precise doses of water and fertilizer directly to the plant’s root zone, avoiding evaporation from the soil. The proposed system can work for both rice and wheat crops without the need to adjust pipes between rotations, saving money and labor. But a transition to more efficient approaches will require new policies and incentives, say the authors.

Self-help groups in Bihar, India, are putting thousands of rural women in touch with agricultural innovations, including mechanization and sustainable intensification, that save time, money, and critical resources such as soil and water, benefiting households and the environment.

The Bihar Rural Livelihoods Promotion Society, locally known as Jeevika, has partnered with the Cereal Systems Initiative for South Asia (CSISA), led by the International Maize and Wheat Improvement Center (CIMMYT), to train women’s self-help groups and other stakeholders in practices such as zero tillage, early sowing of wheat, direct-seeded rice and community nurseries.

Through their efforts to date, more than 35,000 households are planting wheat earlier than was customary, with the advantage that the crop fully fills its grain before the hot weather of late spring. In addition, some 18,000 households are using zero tillage, in which they sow wheat directly into unplowed fields and residues, a practice that improves soil quality and saves water, among other benefits. As many as 5,000 households have tested non-flooded, direct-seeded rice cultivation during 2018-19, which also saves water and can reduce greenhouse gas emissions

An autonomous body under the Bihar Department of Rural Development, Jeevika is also helping women to obtain specialized equipment for zero tillage and for the mechanized transplanting of rice seedlings into paddies, which reduces women’s hard labor of hand transplanting.

“Mechanization is helping us manage our costs and judiciously use our time in farming,” says Rekha Devi, a woman farmer member of Jeevika Gulab self-help group of Beniwal Village, Jamui District. “We have learned many new techniques through our self-help group.”

With more than 100 million inhabitants and over 1,000 persons per square kilometer, Bihar is India’s most densely-populated state. Nearly 90 percent of its people live in rural areas and agriculture is the main occupation. Women in Bihar play key roles in agriculture, weeding, harvesting, threshing, and milling crops, in addition to their household chores and bearing and caring for children, but they often lack access to training, vital information, or strategic technology.

Like all farmers in South Asia, they also face risks from rising temperatures, variable rainfall, resource degradation, and financial constraints.

Jeevika has formed more than 700,000 self-help groups in Bihar, mobilizing nearly 8.4 million poor households, 25,000 village organizations, and 318 cluster-level federations in all 38 districts of Bihar.

The organization also fosters access for women to “custom-hiring” businesses, which own the specialized implement for practices such as zero tillage and will sow or perform other mechanized services for farmers at a cost. “Custom hiring centers help farmers save time in sowing, harvesting and threshing,” said Anil Kumar, Program Manager, Jeevika.

The staff training, knowledge and tools shared by CSISA have been immensely helpful in strengthening the capacity of women farmers, according to Dr. D. Balamurugan, CEO, Jeevika. “We aim to further strengthen our partnership with CSISA and accelerate our work with women farmers, improving their productivity while saving their time and costs,” Balamurugan said.

CSISA is implemented jointly by the International Maize and Wheat Improvement Center (CIMMYT), the International Food Policy Research Institute (IFPRI) and the International Rice Research Institute (IRRI). It is funded by the Bill & Melinda Gates Foundation and the United States Agency for International Development (USAID).

Assessing the effectiveness of a “wheat holiday” for preventing blast

Policy to encourage alternative crops for wheat farmers in South Asia a short-term solution at best, say CIMMYT researchers

Wheat blast — one of the world’s most devastating wheat diseases — is moving swiftly into new territory in South Asia.

In an attempt to curb the spread of this disease, policymakers in the region are considering a “wheat holiday” policy: banning wheat cultivation for a few years in targeted areas. Since wheat blast’s Magnaporthe oryzae pathotype triticum (MoT) fungus can survive on seeds for up to 22 months, the idea is to replace wheat with other crops, temporarily, to cause the spores to die. In India, which shares a border of more than 4,000 km with Bangladesh, the West Bengal state government has already instituted a two-year ban on wheat cultivation in two districts, as well as all border areas. In Bangladesh, the government is implementing the policy indirectly by discouraging wheat cultivation in the severely blast affected districts.

CIMMYT researchers recently published in two ex-ante studies to identify economically feasible alternative crops in Bangladesh and the bordering Indian state of West Bengal.

Alternate crops

The first step to ensuring that a ban does not threaten the food security and livelihoods of smallholder farmers, the authors assert, is to supply farmers with economically feasible alternative crops.

In Bangladesh, the authors examined the economic feasibility of seven crops as an alternative to wheat, first in the entire country, then in 42 districts vulnerable to blast, and finally in ten districts affected by wheat blast. Considering the cost of production and revenue per hectare, the study ruled out boro rice, chickpeas and potatoes as feasible alternatives to wheat due to their negative net return. In contrast, they found that cultivation of maize, lentils, onions, and garlic could be profitable.

The study in India looked at ten crops grown under similar conditions as wheat in the state of West Bengal, examining the economic viability of each. The authors conclude that growing maize, lentils, legumes such aschickpeas and urad bean, rapeseed, mustard and potatoes in place of wheat appears to be profitable, although they warn that more rigorous research and data are needed to confirm and support this transition.

Selecting alternative crops is no easy task. Crops offered to farmers to replace wheat must be appropriate for the agroecological zone and should not require additional investments for irrigation, inputs or storage facilities. Also, the extra production of labor-intensive and export-oriented crops, such as maize in India and potatoes in Bangladesh, may add costs or require new markets for export.

There is also the added worry that the MoT fungus could survive on one of these alternative crops, thus completely negating any benefit of the “wheat holiday.” The authors point out that the fungus has been reported to survive on maize.

A short-term solution?

In both studies, the authors discourage a “wheat holiday” policy as a holistic solution. However, they leave room for governments to pursue it on an interim and short-term basis.

In the case of Bangladesh, the researchers assert that a “wheat holiday” would increase the country’s reliance on imports, especially in the face of rapidly increasing wheat demand and urbanization. A policy that results in complete dependence on wheat imports, they point out, may not be politically attractive or feasible. Also, the policy would be logistically challenging to implement. Finally, since the disease can potentially survive on other host plants, such as weeds and maize—it may not even work in the long run.

In the interim, the government of Bangladesh may still need to rely on the “wheat holiday” policy in the severely blast-affected districts. In these areas, they should encourage farmers to cultivate lentils, onions and garlic. In addition, in the short term, the government should make generic fungicides widely available at affordable prices and provide an early warning system as well as adequate information to help farmers effectively combat the disease and minimize its consequences.

In the case of West Bengal, India, similar implications apply – although the authors conclude that the “wheat holiday” policy could only work if Bangladesh has the same policy in its blast-affected border districts, which would involve potentially difficult and costly inter-country collaboration, coordination and logistics.

Actions for long-term success

The CIMMYT researchers urge the governments of India and Bangladesh, their counterparts in the region and international stakeholders to pursue long-term solutions, including developing a convenient diagnostic tool for wheat blast surveillance and a platform for open data and science to combat the fungus.

A promising development is the blast-resistant (and zinc-enriched) wheat variety BARI Gom 33 which the Bangladesh Agricultural Research Institute (BARI) released in 2017 with support from CIMMYT.However, it will take at least three to five years before it will be available to farmers throughout Bangladesh. The authors urged international donor agencies to speed up the multiplication process of this variety.

CIMMYT scientists in both studies close with an urgent plea for international financial and technical support for collaborative research on disease epidemiology and forecasting, and the development and dissemination of new wheat blast-tolerant and resistant varieties and complementary management practices – crucial steps to ensuring food security for more than a billion people in South Asia.

Wheat Blast Impacts

First officially reported in Brazil in 1985, where it eventually spread to 3 million hectares in South America and became the primary reason for limited wheat production in the region, wheat blast moved to Bangladesh in 2016. There it affected nearly 15,000 hectares of land in eight districts, reducing yield by as much as 51 percent in the affected fields.

Blast is devilish: directly striking the wheat ear, it can shrivel and deform the grain in less than a week from the first symptoms, leaving farmers no time to act. There are no widely available resistant varieties, and fungicides are expensive and provide only a partial defense. The disease, caused by the fungus Magnaporthe oryzae pathotype triticum (MoT), can spread through infected seeds as well as by spores that can travel long distances in the air.

South Asia has a long tradition of wheat consumption, especially in northwest India and Pakistan, and demand has been increasing rapidly across South Asia. It is the second major staple in Bangladesh and India and the principal staple food in Pakistan. Research indicates 17 percent of wheat area in Bangladesh, India, and Pakistan — representing nearly 7 million hectares – is vulnerable to the disease, threatening the food security of more than a billion people.

CIMMYT and its partners work to mitigate wheat blast through projects supported by U.S. Agency for International Development (USAID), the Bill and Melinda Gates Foundation, the Australian Centre for International Agricultural Research (ACIAR), Indian Council for Agricultural Research (ICAR), the CGIAR Research Program on WHEAT, and the CGIAR Platform for Big Data in Agriculture.

CIUDAD OBREGÓN, Mexico (CIMMYT) – As more than 200 wheat science and food specialists from 34 countries gathered in northwestern Mexico to address threats to global nutrition and food security, 9 outstanding young women wheat scientists among them showed that this effort will be strengthened by diversity.

Winners of the Jeanie Borlaug Laube Women in Triticum (WIT) Early Career Award joined an on-going wheat research training course organized by the International Maize and Wheat Improvement Center (CIMMYT), 21-23 March.

“As my father used to say, you are the future,” said Jeanie Borlaug Laube, daughter of the late Nobel Peace Prize laureate, Dr. Norman E. Borlaug, and mentor of many young agricultural scientists. Speaking to the WIT recipients, she said, “You are ahead of the game compared to other scientists your age.”

Established in 2010 as part of the Delivering Genetic Gain in Wheat (DGGW) project led by Cornell University, the WIT program has provided professional development opportunities for 44 young women researchers in wheat from more than 20 countries.

The award is given annually to as many as five early science-career women, ranging from advanced undergraduates to recent doctoral graduates and postdoctoral fellows. Selection is based on a scientific abstract and statement of intent, along with evidence of commitment to agricultural development and leadership potential.

Women who will change their professions and the world

Weizhen Liu, a 2017 WIT recipient and postdoctoral researcher at Cornell University, is applying genome-wide association mapping and DNA marker technology to enhance genetic resistance in tetraploid and bread wheat to stripe rust, a major global disease of wheat that is quickly spreading and becoming more virulent.

“I am eager to join and devote myself to improving wheat yields by fighting wheat rusts,” said Liu, who received her bachelors in biotechnology from Nanjing Agricultural University, China, in 2011, and a doctorate from Washington State University in 2016. “Through WIT, I can share my research with other scientists, receive professional feedback, and build international collaboration.”

Mitaly Bansal, a 2016 WIT award winner, currently works as a Research Associate at Punjab Agricultural University, India. She did her PhD research in a collaborative project involving Punjab Agricultural University and the John Innes Centre, UK, to deploy stripe and leaf rust resistance genes from non-progenitor wild wheat in commercial cultivars.

“I would like to work someday in a position of public policy in India,” said Bansal, who received the Monsanto Beachell-Borlaug scholarship in 2013. “That is where I could have the influence to change things that needed changing.”

Networking in the cradle of wheat’s “Green Revolution”

In addition to joining CIMMYT training for a week, WIT recipients will attend the annual Borlaug Global Rust Initiative (BGRI) technical workshop, to be held this year in Marrakech, Morocco, from 14 to 17 April, and where the 2018 WIT winners will be announced.

The CIMMYT training sessions took place at the Norman Borlaug Experiment Station (CENEB), an irrigated desert location in Sonora State, northwestern Mexico, and coincided with CIMMYT’s 2018 “Visitors’ Week,” which took place from 19 to 23 March.

An annual gathering organized by the CIMMYT global wheat program at CENEB, Visitors’ Week typically draws hundreds of experts from the worldwide wheat research and development community. Participants share innovations and news on critical issues, such as the rising threat of the rust diseases or changing climates in key wheat farmlands.

Through her interaction with Visitors’ Week peers, Liu said she was impressed by the extensive partnering among experts from so many countries. “I realized that one of the most important things to fight world hunger is collaboration; no one can solve food insecurity, malnutrition, and climate change issues all by himself.”

A strong proponent and practitioner of collaboration, Norman E. Borlaug worked with Sonora farmers in the 1940-50s as part of a joint Rockefeller Foundation-Mexican government program that, among other outputs, generated high-yielding, disease-resistant wheat varieties. After bringing wheat self-sufficiency to Mexico, the varieties were adopted in South Asia and beyond in the 1960-70s, dramatically boosting yields and allowing famine-prone countries to feed their rapidly-expanding populations.

This became known as the Green Revolution and, in 1970, Borlaug received the Nobel Peace Prize in recognition of his contributions. Borlaug subsequently led CIMMYT wheat research until his retirement in 1979 and served afterwards as a special consultant to the Center.

When a new, highly virulent race of wheat stem rust, Ug99, emerged in eastern Africa in the early 2000s, Borlaug sounded the alarm and championed a global response that grew into the BGRI and associated initiatives such as DGGW.

“This is just a beginning for you, but it doesn’t end here,” said Maricelis Acevedo, a former WIT recipient who went on to become the leader of DGGW. Speaking during the training course, she observed that many WIT awardees come from settings where women often lack access to higher education or the freedom to pursue a career.

“Through WIT activities, including training courses like this and events such as Visitors’ Week and the BGRI workshop,” Acevedo added, “you’ll gain essential knowledge and skills but you’ll also learn leadership and the personal confidence to speak out, as well as the ability to interact one-on-one with leaders in your field and to ask the right questions.”

CIMMYT is the global leader in publicly-funded maize and wheat research and related farming systems. Headquartered near Mexico City, CIMMYT works with hundreds of partners throughout the developing world to sustainably increase the productivity of maize and wheat cropping systems, thus improving global food security and reducing poverty. CIMMYT is a member of the CGIAR System and leads the CGIAR Research Programs on Maize and Wheat and the Excellence in Breeding Platform. The Center receives generous support from national governments, foundations, development banks and other public and private agencies.

Funded by the Bill & Melinda Gates Foundation and the UK’s Department for International Development (DFID) under UK aid, the DGGW project aims to strengthen the delivery pipeline for new, disease resistant, climate-resilient wheat varieties and to increase the yields of smallholder wheat farmers.

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.
