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.

2018 Agricultural Innovation Program meeting: CIMMYT and partners’ achievements in Pakistan

More than 70 agricultural professionals met in Islamabad, Pakistan, during September 4-5 to discuss agronomy and wheat activities under the Agricultural Innovation Program (AIP) for Pakistan. The event provided a platform for institutions involved in agronomy and the dissemination of agricultural technology and seed to share advances, discuss issues, and plan future undertakings.

“Crop productivity must be increased through research on innovative crop management techniques, varietal development and dissemination of better techniques and seed to farming communities,” said Dr. Yusuf Zafar, Chairman of PARC, addressing participants and touching upon a key theme of the event. He emphasized that precision agriculture, decision support systems, the use of drones, water productivity improvements and more widespread mechanization were on the horizon for Pakistani farmers, but that this would require active involvement of the public and private sectors.

Developments in zero tillage farming and ridge planting were highlighted in the two-day conference as conservation agriculture practices that are gaining traction in national wheat farming, according to Imtiaz Muhammad, CIMMYT representative and AIP project leader.

“In collaboration with a national network of 23 public and private partners, CIMMYT has reached more than 25,000 farmers through trainings on zero tillage, ridge planting, and direct seeded rice farming,” Imtiaz said, adding that support to farmers included nutrient management education the provision of seed planters. “These techniques are helping farmers to save water, avoid residue burning, and reduce their production costs.”

Collaboration with agricultural machinery manufacturers and other private sector actors is leading to local production of Zero Till Happy Seeders, which sow directly into unplowed fields and the residues of previous crops, according to Imtiaz. “Innovative approaches have also resulted in the production of 1,500 tons of wheat seed in 2018,” he explained.

Wheat seed production and farmers’ replacement of older varieties have progressed through local seed banks established by AIP in partnership with Pakistan’s National Rural Support Program (NRSP). Located in villages, the banks sell quality wheat seed for up to 12 percent less than local markets. “This is critical, because Pakistan’s wheat seed replacement is only 30 percent,” said Imtiaz, adding that there is a 50 percent gap between potential wheat yields and the national average yield for this crop.

The AIP will open more seed banks in remote areas of Pakistan, in conjunction with national partners. As well as producing and processing seed, the banks will provide farm machinery contract services and precision agriculture tools at subsidized rates.

Participants’ recommendations included adding straw spreaders to combine harvesters for rice, to facilitate the direct sowing of wheat after rice. They also suggested that agricultural service providers should help promote the direct seeding of rice and wheat with zero tillage implements. Participants observed that, in Baluchistan Province, support to farmers and service providers could increase the adoption of zero tillage for sowing wheat after rice and of precision land leveling, to improve irrigation efficiency and save water.

The AIP and partners will continue to promote water saving and nutrient management techniques, as well as building the capacity of farmers, national staff and agricultural service providers. Finally, those attending recommended that, for its second phase, AIP focus on the biofortification of wheat and rice, climate smart agriculture, decision support tools, women in farming, knowledge delivery, appropriate mechanization, nutrient management, weed management and water productivity.

AIP is the result of the combined efforts of the Pakistan Agriculture Research Council (PARC), the International Livestock Research Institute (ILRI), the International Center for Agricultural Research in the Dry Areas (ICARDA), the International Rice Research Institute (IRRI), the World Vegetable Center (AVRDC), the University of California at Davis, and the International Maize and Wheat Improvement Center (CIMMYT). It is funded by the United States Agency for International Development (USAID). With these national and international partners on board, AIP continues to improve Pakistan’s agricultural productivity and economy.

ISLAMABAD, Pakistan (June 30, 2017) – Farmers in Pakistan are eagerly adopting a nutrient-enhanced wheat variety offering improved food security, higher incomes, health benefits and a delicious taste.

Known as Zincol and released to farmers in 2016, the variety yields harvests as high as other widely grown wheat varieties, but its grain contains 20 percent more zinc, a critical micronutrient missing in the diets of many poor people in South Asia.

Due to these benefits and its delicious taste, Zincol was one of the top choices among farmers testing 12 new wheat varieties in 2016.

“I would eat twice as many chappatis of Zincol as of other wheat varieties,” said Munib Khan, a farmer in Gujar Khan, Rawalpindi District, Punjab Province, Pakistan, referring to its delicious flavor.

Khan has been growing Zincol since its release. In 2017, he planted a large portion of his wheat fields with the seed, as did members of the Gujar Khan Seed Producer Group to which he belongs.

The group is one of 21 seed producer associations established to grow quality seed of new wheat varieties with assistance from the country’s National Rural Support Program (NRSP) in remote areas of Pakistan. The support program is a key partner in the Pakistan Agricultural Innovation Program (AIP), led by the International Maize and Wheat Improvement Center (CIMMYT) and funded by the U.S. Agency for International Development.

“Over the 2016 and 2017 cropping seasons, 400 tons of seed of Zincol has been shared with farmers, seed companies and promotional partners,” said Imtiaz Muhammad, CIMMYT country representative in Pakistan and a wheat improvement specialist.

ISLAMABAD, Pakistan (February 1, 2017) – Pakistani and the International Maize and Wheat Improvement Center (CIMMYT) scientists are working with wheat farmers to test and promote precision agriculture technology that allows the farmers to save money, maintain high yields and reduce the environmentally harmful overuse of nitrogen fertilizer.

Wheat is planted on more than 9 million hectares in Pakistan each year. Of this, 85 percent is grown under irrigation in farming systems that include several crops.

Fast-tracking wheat seed deployment in remote Pakistan regions

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.

ISLAMABAD, Pakistan (June 1, 2015)- In response to rapidly-changing food preferences in Pakistan, including a latent unmet demand for pasta products, CIMMYT-Pakistan has been working to develop the country’s durum wheat market and varieties that satisfy the required grain quality attributes, in addition to high yields and disease resistance.

According a 2014 study by the Woodrow Wilson International Center for Scholars, Pakistan is urbanizing at an annual rate of 3 percent—the fastest pace in South Asia. “More Pakistanis are living in cities than ever before,” said Krishna Dev Joshi, CIMMYT wheat improvement specialist. “As a result, demand for durum wheat products like macaroni or spaghetti is rising. But farmers are not growing durum wheat because there is no a clear price advantage or assured markets. At the same time, private investors will not develop new milling facilities or markets without guarantees of durum wheat grain supplies from farmers.”

To help break the impasse, CIMMYT has been testing and evaluating 925 durum wheat lines in Pakistan since 2011, and identified 40 durum wheat lines as having appropriate combinations of high yield, protein, yellowness and sedimentation. The yield stability of lines across locations and years indicates that durum wheat could be grown in environments similar to those of the trial sites, increasing the chances for uptake of this new crop. “One challenge, though,” said Joshi, “is that durum yields were only slightly higher than those of bread wheat, posing a challenge for the uptake by farmers of durum wheat.”

WHEAT and CIMMYT Remember Vital Legacy of Gender Specialist Paula Kantor

Men’s Roles and Attitudes: Key to Gender Progress

PaulaKantor-mrBy Mike Listman/CIMMYT

EL BATAN, Mexico (March 3, 2015)- Gender research and outreach should engage men more effectively, according to Paula Kantor, CIMMYT gender and development specialist who is leading an ambitious new project to empower and improve the livelihoods of women, men and youth in wheat-based systems of Afghanistan, Ethiopia and Pakistan.

“Farming takes place in socially complex environments, involving individual women and men who are embedded in households, local culture and communities, and value chains — all of which are colored by expectations of women’s and men’s appropriate behaviors,” said Kantor, who gave a brownbag presentation on the project to an audience of more than 100 scientists and other staff and visitors at El Batán on 20 February. “We tend to focus on women in our work and can inadvertently end up alienating men, when they could be supporters if we explained what we’re doing and that, in the end, the aim is for everyone to progress and benefit.”

Funded by Germany’s Federal Ministry for Economic Cooperation and Development, the new project will include 14 village case studies across the three countries. It is part of a global initiative involving 13 CGIAR research programs (CRPs), including MAIZE and WHEAT. Participants in the global project will carry out 140 case studies in 29 countries; WHEAT and MAIZE together will conduct 70 studies in 13 countries. Kantor and Lone Badstue, CIMMYT’s strategic leader for gender research, are members of the Executive Committee coordinating the global initiative, along with Gordon Prain of CIP-led Roots, Tubers and Bananas Program, and Amare Tegbaru of the IITA-led Program on Integrated Systems for the Humid Tropics, with expert advisement from specialist Patti Petesch, who contributed to World Bank studies such as “On Norms and Agency” and “Voices of the Poor.

“The cross-CRP gender research initiative is of unprecedented scope,” said Kantor. “For WHEAT, CIMMYT, and partners, understanding more clearly how gendered expectations affect agricultural innovation outcomes and opportunities can give all of our research more ‘ooomph’, helping social and biophysical scientists to work together better to design and conduct socially and technically robust agricultural R4D, and in the end achieve greater adoption and impact.”

ISLAMABAD, Pakistan (February 13, 2015)- Lack of access to seed of improved wheat varieties is holding back harvests of smallholder wheat farmers in remote areas of Punjab, Pakistan, a group of farmers told representatives of seed companies, input dealers and research, extension and development organizations, at a workshop last fall in Chakwal, Punjab, Pakistan.

“Ninety-five percent of farmers in Pothwar, a semiarid region of bare and broken terrain, use farm-saved seed of outdated varieties, invariably with limited use of modern agricultural technologies and inputs, resulting in poor crop establishment and low yields,” said Krishna Dev Joshi, CIMMYT wheat improvement specialist based in Pakistan and who helped organize the workshop. “Their yields average only 0.6 tons per hectare, compared to progressive farmers in irrigated areas who harvest ten times that amount.”

Joshi explained that the same three wheat varieties cover 83 percent of the region and have been used for the past 24 years. “One of these, C591, is a variety that was recommended in 1934 and is still grown on about 14 percent of the region’s nearly 0.6 million hectares of wheat area.”
