Partnership on maize lethal necrosis in Africa makes significant progress

Written by on August 19, 2014. Posted in News.

Partners of the Maize Lethal Necrosis (MLN) project in Africa, funded by the Bill & Melinda Gates Foundation and Syngenta Foundation for Sustainable Agriculture (SFSA), came together to review and discuss the progress and next steps for the project at a workshop on 14-15 May.

“The primary goal of this project is to identify MLN-tolerant germplasm, including inbred lines and pre-commercial hybrids, for potential deployment of MLN-tolerant varieties (with other relevant adaptive traits) through partners in Sub-Saharan Africa. The project also seeks to gain information regarding the genetics of resistance to the disease, create awareness and build capacity for more effective MLN management.

“As the project matures, we will be screening additional promising germplasm coming out of the MLN screening facility at Naivasha and from national agricultural research institute (NARI) partners at satellite testing centers in Kenya, Tanzania and Uganda under high natural disease pressure. This will help to validate the performance of the germplasm under MLN in important agro-ecologies,” said CIMMYT Global Maize Program Director and MLN-Africa project leader, BM Prasanna.

Mike Robinson, chief scientific advisor at SFSA and representatives of several seed companies and NARIs in Kenya, Tanzania and Uganda participated in the MLN Field Day at Naivasha on 14 May. The companies included East African Seed, Kenya Seed Company, Meru Agro, Monsanto, DuPont Pioneer and Seed Co Limited. “We hope to submit several germplasm entries for trials at the MLN screening facility in the next planting season,” said Francis Ndambuki, a maize breeder with Kenya Seed Company.

Less than a year after its opening, the MLN screening facility is now fully functional, evaluating materials from several partner organizations, including the International Institute for Tropical Agriculture, NARIs and seed companies. The partners/ visitors had an opportunity to see several trials taking place at the facility, as well as promising MLN-tolerant germplasm. Scientists involved in this project are working intensively – in collaboration with national and international institutions to develop and validate virus inoculation and germplasm screening protocols. They are also testing a large array of germplasm for responses against MLN under artificial inoculation, developing diagnostic techniques and building the capacity of national partners in MLN diagnostics and management.

The CIMMYT seed systems team is working on scaling-up the identified MLN-tolerant germplasm and distributing it to interested public and private partners in Africa. The progress made on the project’s diverse fronts was presented in detail, and the next steps were discussed during the project meeting held in Nairobi on 15 May. “We are pleased that CIMMYT teamed with KARI to address this important issue for Africa,” said Joseph Mureithi, KARI deputy director. Mureithi continued, “The MLN screening facility at Naivasha is a model of partnership between CGIAR centers, NARIs and the private sector,” adding that the results of the trials at the facility would have far-reaching impact. “Stresses such as drought and poor soil fertility could potentially compound the expression of the MLN disease,” said KARI virologist Dr. Anne Wangai, a key partner in this project. “This is a great opportunity to demonstrate the confluence of technologies – breeding, pathology and entomology,” said Robinson, urging the project partners to further strengthen the scientific edge and demonstrate how the research being undertaken on the disease can quickly result in products that benefit African farmers affected by the disease.

“Policy advocacy is key,” said Wilfred Mwangi, CIMMYT’s regional representative for Africa. He emphasized the need to fast-track registration and commercialization of the MLN-tolerant hybrids, especially in the MLN-affected countries. The Kenya Plant Health Inspectorate Service (KEPHIS) was commended for its commitment and support in fast-tracking the release of promising MLN-tolerant hybrids. “There is fast progress on the MLN research and the first wave of improved materials is coming now,” said Robinson, adding that he is looking forward to seeing more materials in the future. He emphasized the importance of coordination, policy clarity, communication and international synergies on MLN research and development in Africa.

CIMMYT scientists working on the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) have identified the most suitable maize varieties for high temperature and drought-prone environments in Zimbabwe. The scientists have been conducting research on drought- and heat-tolerant maize varieties in areas that are vulnerable to climate variability and climate change in Zimbabwe. Working in collaboration with Sustainable Agriculture Technology (SAT), a local NGO, the scientists are testing the suitability of drought- and heat-tolerant varieties as a solution to challenges farmers face in “climate hotspots.”
These farmers are vulnerable to climate change due to erratic and limited rainfall, a situation that is worsened by increasing temperatures. “To identify these areas, we looked at climate change patterns across Zimbabwe which allowed us to identify five wards: Bikita, Gokwe, Gutu, Mutare and Zaka,” said CIMMYT physiologist Dr. Jill Cairns. The scientists then downscaled projections of monthly changes in rainfall and temperature in these wards to confirm their vulnerability and get a better understanding of the seasonal changes likely to occur by 2050.

In this maize demonstration plot, crop management was done using hand weeding.

In partnership with SAT, scientists are screening drought- and heat-tolerant maize varieties in demonstration plots using different farmer-managed practices that are accessible to local communities. “SAT has very good links to extension leaders, which has helped us reach the community,” said Cairns. “It holds field days at each demonstration location and has managed to engage locally.” During these events, farmers are provided with information on climate change, improved maize varieties and modern agricultural practices. Cairns said highlights from field days she has attended included seeing schoolchildren sing about climate change and agriculture, and a group of HIV-positive women singing about agriculture and improved seed. The drought-tolerant maize varieties used in this study are from the Drought Tolerant Maize for Africa (DTMA) project breeding pipeline, which is funded by the Bill & Melinda Gates Foundation. The research on heat is a component of DTMA being funded by the U.S. Agency for International Development (USAID).

Boosting productivity of smallholder farms in Nepal, India and Bangladesh

CIMMYT will lead a new research initiative to make agriculture more productive, profitable and sustainable for smallholder farmers in the Eastern Gangetic Plains (EGP) of Nepal, Bangladesh and India.
Launched in Dhulikhel, Nepal, on 4 July, the five-year US$6.8 million regional research initiative, Sustainable and Resilient Farming Systems Intensification in the Eastern Gangetic Plains (SRFSI), will tap the agricultural potential of the area and target 7,000 farmers to test and adopt appropriate new technology and farming approaches.

The program, funded by the Australian Centre for International Agricultural Research (ACIAR), will operate in eight districts: two in northwest Bangladesh, two in the eastern Terai of Nepal and two each in the Indian states of Bihar and West Bengal.

The three-day Inception and Planning Meeting that launched the program was attended by 84 participants from Australia, Bangladesh, India, Mexico and Nepal. SRFSI is managed by CIMMYT on behalf of multiple partners including the national research and extension systems of Bangladesh, India and Nepal, Indian and Australian universities, national and international nongovernmental organizations, the Commonwealth Scientific and Industrial Research Organisation of Australia and four CGIAR Centers (CIMMYT, the International Rice Research Institute, the International Food Policy Research Institute and the International Water Management Institute).

The project was officially initiated by the Australian Ambassador to Nepal, Glenn White, together with the Executive Director of the Nepal Agricultural Research Council (NARC), Dr. Dil Bahadur Gurung; the Joint Secretary of the Nepal Ministry of Agricultural Development, Dr. Rajendra Prasad Adhikari; Dr. Claire Glendenning of the Australian Department of Foreign Affair and Trade; and Dr. John Dixon, principal adviser for ACIAR.

“This initiative will help to raise agricultural productivity in a region which has the potential to become one of Asia’s great food bowls,” White told the gathering of scientists and development practitioners.

The EGP is home to some 300 million people, with the world’s highest concentration of rural poverty and a strong dependence on agriculture for food security and livelihoods. The region is dominated by small farms with many female farmers who have little access to credit, quality seeds, fertilizers, irrigation or formal extension services. They also have to contend with climate-related risks and extreme events such as floods, drought and cold snaps.

“This program will allow farmers to test a range of innovations to help them boost food production, including conservation agriculture and efficient use of water resources, while strengthening their ability to adapt and link to markets and support services,” White said. “Our aim is to enable at least 130,000 farmers to adopt these technologies within the next 10 years.”

Gurung and Adhikari lauded the long-term partnership between CIMMYT and Nepal, as well as the ACIAR support of this project, and assured that the Ministry will extend its full support.

Key Objectives of the SRFSI

The Eastern Gangetic Plains region has the potential to become a major contributor to South Asian regional food security, but rice and wheat productivity remain low and diversification is limited because of poorly developed markets, sparse agricultural knowledge and service networks, and inadequate development of available water resources and sustainable production practices. Labor shortages – mainly during sowing and harvesting – are becoming more acute. These factors lead to smallholder vulnerability to climate and market risks that limit investments in new technologies.

SRFSI will undertake several high-priority activities to reduce these factors:

• Improving farmers’ access to inputs, services and market information in order to reduce the risk associated with adopting new practices.

• Removing policy barriers to technology adoption.

• Analyzing the appropriateness of technologies, service provider models, markets and policies for women farmers, and adjusting them where necessary, to help ensure food security and gender equity in the region.

• Developing new knowledge among farmers, researchers, extension and change agents, service providers, agro-dealers and others involved in agriculture. This has been identified as the key to achieving widespread adoption of new technologies and reductions in poverty in the EGP.

• Investing heavily in capacity building at multiple levels, from field days to short courses to linkages with advanced research institutions. Ultimately the project focal communities, where all aspects of the project activities are put into place to achieve the desired change, will become demonstration or learning sites for institutions or individuals interested in agricultural development, where they can observe the technological changes and talk with farmers and farmer organizations about the importance of the different components of the project in bringing about agriculture change.

Seed health facilities upgraded in Turkey

Written by on April 2, 2014. Posted in News.

A grant provided by the CGIAR Research Program on Wheat (CRP WHEAT) has helped improve seed health facilities in Turkey.

The grant benefited the International Winter Wheat Improvement Program (IWWIP), a cooperative program between the Turkish Ministry of Food, Agriculture and Livestock, CIMMYT and ICARDA. IWWIP develops germplasm for Central and West Asia and facilitates the development and spread of global winter wheat germplasm and related knowledge. IWWIP focuses on wheat mega-environments that are home to about 20 million wheat-dependent poor who make less than US$ 2 a day.

IWWIP operates within the framework of Turkish public research institutes, including the Bahri Dagdas International Agriculture Research Institute. Annually, tens of thousands of envelopes containing improved germplasm are prepared for distribution to IWWIP partners globally. Seed sent from Turkey must meet the highest seed health requirements.

With this in mind, the Bahri Dagdas institute applied for a collaboration grant from CRP WHEAT in 2012 to upgrade its seed health facilities; an effort that could not be funded from the regular IWWIP budget. The grant targeted improvement of infrastructure and facilities as well as staff training. For example, staff member Gul Imriz attended an advanced pathology course at CIMMYT-Mexico and a training event on seed health.

By the start of the 2014 season, the new facility will be fully equipped and ready to use for seed cleaning, washing and treatment. IWWIP acknowledges the contributions of Fatih Ozdemir, director of the Bahri Dagdas International Agriculture Research Institute; Mesut Keser, ICARDA representative in Turkey; Monica Mezzalama, head of CIMMYT’s Seed Health Unit; and Victor Kommerell, CRP WHEAT program manager.

Nutrient management tool wins award

Written by Sam Storr on February 12, 2014. Posted in News.

A tool developed by CIMMYT and the International Plant Nutrition Institute (IPNI) offering site-specific nutrient management (SSNM) advice to help farmers achieve higher yields more efficiently recently won an innovation award.

Nutrient Expert^TM decision support tools received the best innovation award in the information and communications technology category at the Bihar Innovation Forum II, which recognizes innovations to improve rural livelihoods in India. These tools were in development by CIMMYT and IPNI for five years and were launched in June 2013.

In South Asia, 90 percent of smallholder farmers do not have access to soil testing. The computer-based support tools aim to provide them with simple advice on how to get the most from fertilizer inputs. An IPNI study funded by the CGIAR Research Program on Maize (MAIZE CRP) Competitive Grant Initiative (CGI) found that farming practices and the resources available to farmers vary hugely in east India.

The cutting-edge value of Nutrient Expert^TM is that it offers specific information at the farm level, where it can provide the greatest benefits. Nutrient Expert^TM is especially relevant because it was developed through dialogue and participation with stakeholders, which also raises awareness and eventual adoption by users.

It is now used by the Indian National Agricultural Research System and is a key intervention used by the CRP on Climate Change, Agriculture and Food Security (CCAFS) in its Climate Smart Villages. The Nutrient Expert^TM approach is also being applied to maize and wheat in other areas of Southeast Asia, China, Kenya and Zimbabwe.

Machinery book published in Bangladesh

Written by on February 3, 2014. Posted in News.

A new, open-source book on agricultural machinery in Bangladesh is now available online. Made in Bangladesh: Scale-appropriate machinery for agricultural resource conservation was written by authors from CIMMYT and the Bangladesh Agricultural Research Institute. The book was a product of the USAID-funded Cereal Systems Initiative for South Asia – Mechanical and Irrigation (CSISA-MI) and CSISA Bangladesh projects, as well as the EU-funded Agriculture, Nutrition and Extension Project (ANEP) and the Australian Centre for International Agricultural Research-funded Rice-Maize Project.

Machinery-Book

The book details the functions and designs of smallscale agricultural machinery used in conjunction with two-wheel tractors (2WTs). 2WTs are used extensively in Bangladesh and several other countries, and the small-scale implements extend the usefulness of the 2WTs. Most implements are compatible with conservation agriculture-based management practices while the book’s technical drawings allow manufacturers and engineers to reproduce and improve upon the original designs. The PDF version of the book, which is found here in the CIMMYT repository, is open access and can be downloaded and shared. The book will soon be translated and released in Bangla. For more information, contact Tim Krupnik, CIMMYT cropping systems agronomist, at t.krupnik@cgiar.org.

Trees keep Ethiopia’s wheat cool and productive

Written by on November 21, 2013. Posted in News.

By Frédéric Baudron/CIMMYT

Researchers with CIMMYT’s Global Conservation Agriculture Program (GCAP) in Ethiopia have found that use of agroforestry systems involving an indigenous tree could mitigate climate change effects in Ethiopian smallholder wheat systems. Specifically, their study showed that maximum temperatures under the canopy of Faidherbia albida, a nitrogen-fixing, acacia-like species found throughout African savannas, were constantly 4 to 5°C lower than temperatures outside the canopy.

Wheat grows under the canopy of F. albida around mid-October in Mojo area, Ethiopia.

By 2050, the maximum daily temperature in wheat-growing areas of Ethiopia is predicted to rise by 2 to 3°C. This could significantly reduce yields of wheat, a crop that accounts for 18 percent of Ethiopia’s cereal area and nearly a fifth of its cereal production. The crop is key to the food security and incomes of smallholder farmers who grow it. CIMMYT researchers are studying the effect of scattered trees that are currently common in farmers’ field.

Keeping trees in fields for the production of firewood and fencing materials is extremely common in Ethiopia. “But these trees have other functions and may positively affect the productivity of crops underneath,” said Frédéric Baudron, CIMMYT cropping systems agronomist based in Ethiopia. In addition to more wheat-friendly temperatures, the benefits of F. albida in wheat systems are manifold, according to Baudron. “Soil moisture increases greatly under the canopy, resulting in a greener wheat crop for a longer period of time,” Baudron said. “The presence of F. albida also fosters longer wheat leaf blades, a greater number of tillers per plant, longer spikes and a higher number of seeds per spike — all of which translates into higher stover and grain yields.” Moreover, the incidence of wheat diseases like fusarium wilt and head smut diminishes under the tree canopy.

Under the World Agroforestry Centre (ICRAF)-led project Trees4Food, funded by the Australian International Food Security Centre (AIFSC) and managed by the Australian Centre for International Agricultural Research (ACIAR), GCAP-Ethiopia studies interactions between food crops and various indigenous trees in wheat- and maize-based systems. In the case of F. albida, there are no tradeoffs between the provision of tree products and the crop yield underneath. Research aims to come up with management practices – such as proper fertilization rates, genotypes of crops, pruning management and tillage practices – that maximize the existing synergy.

With other tree species commonly found in Ethiopian fields (such as Acacia tortilis, Cordia africana, or Croton macrostachyus), these tradeoffs are often substantial. In that case, research aims to come up with management practices that minimize competition. The project is being implemented in Ethiopia as well as Rwanda.

Asia wheat breeders review progress and look ahead

Written by on October 25, 2013. Posted in News.

By Arun Joshi /CIMMYT

Over the past five years, more than a dozen new stress tolerant wheat varieties have become available to farmers in South Asia, through breeding research and partnerships as part of the Cereal Systems Initiative for South Asia (CSISA), according to Arun K. Joshi, CIMMYT wheat breeder. Joshi said that germplasm exchange with CIMMYT had increased significantly; that most advanced breeding lines in CIMMYT trials were resistant to Ug99 stem rust and other rusts; more segregating generation lines from South Asia were being sent to Njoro, Kenya, for stem rust resistance screening; the use of physiological tools to select for heat and drought tolerance in the region had increased; links among breeders, seed producers and farmers had strengthened; and capacity building had been promoted.

These and other achievements, as well as challenges and opportunities for improvement, came to light in two recent review meetings in Dhaka, Bangladesh. From 6 to 8 October, 56 scientists from Bangladesh, Bhutan, India and Nepal, as well as representatives of government councils and ministries, research centers, agricultural institutes and universities, convened for CSISA’s 5th wheat breeding review meeting. Participants also attended the 2nd review and work plan meeting for the project, “Increasing the productivity of the wheat crop under conditions of rising temperatures and water scarcity in South Asia,” funded by the Federal Ministry for Economic Cooperation and Development, Germany. The meetings were organized by Joshi, team leader of the two projects in South Asia, and facilitated by CIMMYT’s Dhaka office, led by T.P. Tiwari. CIMMYT was represented in the meetings by scientists from Bangladesh, India and Nepal and a consultant from Cambridge.

The CSISA meeting reviewed the progress of the 2012-13 wheat cycle and established work plans for the 2013-14 crop cycle. The event was inaugurated by chief guest Khalid Sultan, director of research at the Bangladesh Agricultural Research Institute (BARI), and R.P. Dua, assistant director general for the Indian Council of Agricultural research (ICAR). Dua praised the regional focus and presence of CSISA wheat breeding, and Sultan said “the South Asia-CIMMYT collaboration is paramount to the food security of the region.” Ten participating research centers presented reports and work plans.

Participants discussed how to strengthen links among wheat breeding, fast-track seed production, distribute new, improved varieties to farmers and work on conservation agriculture and participatory variety selection. Wheat breeders, pathologists, physiologists, agronomists and soil scientists attended the “Increasing the productivity of the wheat crop” meeting, which addressed project work plans and progress in breeding and agronomy.

Six Indian research centers reported on progress in evaluating more than 3,300 wheat lines screened last cycle for early sowing, as well as the 2013-14 work plan. The top 50 lines will be used to develop two trials in India: one for the northwestern plains and one for the central and peninsular zone, Joshi said. He also presented the highlights of the molecular research by Marion Roder, Leibniz Institute of Plant Genetics and Crop Plant Research, Germany, and Susanne Dreisigacker, CIMMYT molecular breeder, in screening some 3,000 wheat lines for genes controlling vernalization and response to changes in day length.

Partnerships lead to measurable impacts for Drought Tolerant Maize for Africa

Written by on October 22, 2013. Posted in Features.

The Drought Tolerant Maize for Africa (DTMA) project is an outgrowth of more than a decade of maize physiology research. It builds on more than 10 years of promoting the inclusion of selection for drought tolerance in maize breeding programs in Sub-Saharan Africa and the widespread development and regional testing of stress-tolerant varieties. DTMA is funded by the Bill & Melinda Gates Foundation with past support from the Howard G. Buffett Foundation, USAID, the UK Department for International Development (DFID), the Swiss Agency for Development and Cooperation (SDC), the German Federal Ministry for Economic Cooperation and Development (BMZ), the International Fund for Agricultural Development (IFAD) and the Eiselen Foundation. This blog post was originally published by CGIAR.

Currently, maize production supports the livelihoods of approximately 300 million people in sub-Saharan Africa (SSA). Climate change variability and the prevalence of extreme events, especially droughts, are a harsh reality for smallholder farmers in Africa who depend on rainfed agriculture. Maize production in Africa is almost completely rainfed and droughts plague approximately a quarter of the maize crop, resulting in losses as high as half the harvest. Extended periods of droughts therefore, adversely affect not only crop yields but also the livelihoods of African farmers. Economic analyses suggest that, if widely adopted, drought-tolerant maize seed can help African farmers cope with such impediments.

On a recent visit to the annual meeting of the Drought Tolerant Maize for Africa (DTMA) initiative held in Nairobi, I was privy to some evidence of research impact in this area, which I found to be quite significant. The Drought Tolerant Maize for Africa (DTMA) project (launched in 2006) seeks to mitigate drought and other barriers to production in the region.

Here are some highlights of key data on the measurable impacts of the DTMA project and a snapshot of some lessons learned during my time there. Not only will this information be useful for future partnerships but it can also be used to inform our processes during the 2nd call for proposals for the CGIAR Research Programs.
The DTMA project started in 2006. Here are the targets that the project has achieved thus far (in 2013) in terms of measurable impact:
◦140 new DTMA varieties released,
◦30,000 tons of seed (17,000 T from new varieties) produced last year in 13 African countries (Angola, Benin, Ethiopia, Ghana, Kenya, Malawi, Mali, Mozambique, Nigeria, Tanzania, Uganda, Zambia, and Zimbabwe)
◦An impact efficiency study (presented during the meeting) which indicated that several countries were able to reach their objectives in terms of seed production; Zimbabwe and Kenya were able to double their previous expected figures
◦ 110 African seed companies (72 small-national, 18 regional, 12 small and medium enterprises (SMEs), and 8 international enterprises) have adopted, produced and spread the new DTM varieties to local farmers,
◦ 1,230, 000 hectares planted with these new varieties, and
◦3 million households and 20 million people in total benefited and reached.

DTMA partners made certain that complete accountability was applied to the partnership network in order to ensure that the impact of research outcomes could be quantified. Thanks to this well-designed management model, researchers involved in the DTMA initiative were able to not only produce high quality research outputs but also ensure that research outcomes were adopted and scaled up. In addition, local facilities for Doubled Haploid (DH) production from tropical and sub-tropical maize germplasm have also been set up at the KARI (Kenyan Agriculture Research Institute) Kiboko Station.

Capacity building works to combat wheat rusts

Written by on October 17, 2013. Posted in News.

For the fifth consecutive year, scientists from around the world met at the Kenya Agricultural Research Institute (KARI) facility in Njoro for training on “Standardization of Stem Rust Note-taking and Evaluation of Germplasm.” The course, conducted 22 September to 2 October, attracted 30 scientists from 15 countries (Bangladesh, Bhutan, Egypt, Ethiopia, India, Kenya, Mexico, Nepal, Pakistan, Rwanda, Sudan, Uganda, United States, Yemen and Zambia). The course created increased awareness about the threat of rusts (especially Ug99) on wheat production. The wheat research scientists were trained on new approaches in fighting the rust diseases (including genetics, pathology, breeding and molecular genetics) and taught common approaches in identifying, scoring and evaluating rust diseases both in the field and in experimental plots.

Practical demonstrations focused on rust methodologies and handson experience in recording disease scales both in the greenhouse and field, according to Sridhar Bhavani, CIMMYT wheat pathologist/ breeder and course coordinator. Participants had the opportunity to work with the East African component of the Borlaug Global Rust Initiative (BGRI) and Durable Rust Resistance in Wheat (DRRW) projects in Kenya. These are designed to monitor further migration of Ug99 and its variants; facilitate field screening of international germplasm; identify new sources of resistance; understand the genetic basis of resistance; develop durable, targeted breeding programs; and enhance the capacity of national programs. Participants had the opportunity to interact with international scientists, and trainers learned of emerging problems from the participants.

Attendees also visited the KARI breeding program and farmers’ fields to inspect the new varieties. Members of CIMMYT’s Board of Trustees and Management Committee as well as KARI dignitaries also visited the screening site at KARI Njoro on 26 September and interacted with Oliver Nightingale from Menangai Farms, a progressive farmer who demonstrated one of the new varieties (“Kenya Robin”) which was planted on 1,000 acres of his farm near Njoro. “Wheat farmers in Kenya have benefited greatly with the new varieties developed by CIMMYT and released by KARI. These varieties are not only resistant to rust but generate yields 10 to 15 percent higher than the local varieties and are resistant to stem rust,” Nightingale told the group. Two varieties – “Kenya Robin” and “Kenya Eagle” – are CIMMYT introductions which have become very popular with farmers and currently occupy 25 to 30 percent of the wheat area in Kenya. “Kenya Robin has bold grains, good straw strength, still stands after three hail storms and yields between 6.8-7 tons per acre, whereas the older variety ‘Kwale’ lodged flat in farmers’ fields in similar conditions,” added Nightingale.

He thanked CIMMYT and KARI for introducing high-yielding varieties in Kenya. The 2013 main season screening nursery has more than 25,000 wheat accessions from 15 countries and research institutions to be evaluated for resistance to Ug99 and close to 50,000 accessions are tested every year. According to Bhavani, more than 300,000 lines have been tested at KARI-Njoro since 2006 and eight varieties have been released since 2008 in Kenya and more than 40 Ug99-resistant varieties/advanced lines have been released globally. “Every year as a part of CIMMYT-Kenya shuttle breeding nearly 1,000 F3 and F4 populations are selected under high disease pressure for two generations at KARI-Njoro and several high-yielding lines with good levels of Ug99 resistance have been identified,” added Ravi Singh, CIMMYT distinguished scientist.

The KARI-CIMMYT screening nursery has produced global benefits that go beyond Kenya’s borders – with spillover effects reaching neighboring countries including Ethiopia, Tanzania, Uganda and Zambia. “Commitment to the cause through global partnership, free exchange of germplasm, scientific expertise and donor funding have been the key features leading to the success of this project,” said Hans Braun, director of CIMMYT’s Global Wheat Program. He continued, stating, “CIMMYT Board members were impressed with the progress in the fight against Ug99, the logistics that go into operating this global rust screening platform in Njoro and the impact that has been achieved through release and adoption by farmers of rust-resistant varieties around the globe.” The annual course is part of the wider BGRI/DRRW project in Kenya, an initiative of Cornell University that is being implemented by CIMMYT and KARI in collaboration with 16 other research institutions worldwide. The project is funded by the Bill & Melinda Gates Foundation and the UK Department for International Development. To date, more than 100 pathologists, breeders and geneticists have been trained at KARI-Njoro. Scientists from Australia, Kenya, the United States and CIMMYT lectured on several aspects of wheat rust research. As Zambian participant Lutangu Makweti said: “It time for us to utilize the knowledge gained in the training course and implement better surveys and breeding activities in our countries.” Participants thanked CIMMYT and KARI for the opportunity to learn about rusts, the practical, handson training and the opportunity to interact with the global rust community. The long-term partnership between CIMMYT and KARI is achieving numerous milestones in the fight against the Ug99 race group and producing outcomes that benefit the entire global wheat community.

CIMMYT launches mobile phone voice messaging for climate-smart villages in India

Written by on September 19, 2013. Posted in News.

A new pilot program is trying to reach farmers in India with information on weather, pests and climate change — through their mobile phones. CIMMYT launched the “Dissemination of climate smart agro-advisories to farmers in CCAFS benchmark sites of India” project on 15 August in four villages of the Karnal District in the State of Haryana and in the Vaishali District in the State of Bihar on 1 September. The project is led by CIMMYT‘s Surabhi Mittal with IFFCO Kisan Sanchar Limited as the content partner and Kisan Sanchar as the dissemination and implementing agency.

The project has aims to help farmers clarify information about climate-smart technology; help them adopt technologies that could mitigate their risks due to climate change; and to measure how receiving information on mobile phones affects farmers. Its reach covers 1,200 male and female farmers in eight villages and will run for 8 months on a pilot level. Farmers whose mobile numbers are in the project database receive two voice messages every day along with detailed SMS messages – in Hindi when required. These messages give weather predictions, information about pests and remedies, details of climate smart technologies and general information about climate change and solutions. Some farmers belong to the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) climate smart villages and some belong to control villages in the Karnal and Vaishali districts.

Challenges building this mobile number database included farmers who could not receive messages from unknown numbers. The project team worked with farmers to authorize the messages and get permission from the Telecom Regulatory Authority of India to unblock them. Encouraging women to participate was another hurdle. Due to cultural barriers, men were not willing to share the contact numbers of their wives. Awareness and focus group discussions held in Karnal from 29 to 30 August helped solve the issue. Project Leader Mittal met the Sarpanch, or the elected head, of the villages as well as with government women health workers known as Anganwadi workers. The four villages in Karnal have women Sarpanch, helped mobilize women farmers and women in households headed by men. In Bihar, a female scout is working closely with women farmers and has created women’s groups to for the project.

Customized feedback is built into the project. First, a helpline allows farmers to give feedback and ask for responses to questions. Some questions are instantly sorted out, some are diverted to other experts and some responses are collected and the farmer is called later. The feedback is converted the next day into voice messages if it is relevant to a wider group of farmers. The other form of feedback is filtered back by field scouts who interact closely with the farmers, frequent focus group discussions and through a bi-weekly structured feedback form. Efforts are being made to make the information more relevant, timely, customized and useful for the farmers. The research and field teams have to work closely and proactively to meet the farmers’ diverse requests. Efforts to compile farmers’ correct phone numbers and to make farmers aware of the benefits of learning about new technologies are great challenges. But the enthusiasm of farmers – shown through an increased listening rate to the voice messages and an increasing number of calls to the helpline – is a great motivation for the project team.

Rastrojo-de-maíz Introducing maize stover into India’s commercial dairy systems could mitigate fodder shortages and halt increasing fodder costs, according to new research by CIMMYT and the International Livestock Research Institute (ILRI). The two organizations collaborated on the Cereal Systems Initiative for South Asia project (CSISA), which is funded by the Bill & Melinda Gates Foundation (BMGF), as well as the CGIAR Research Program on MAIZE. Their study shows that while significant variations exist among maize cultivars in terms of their stover quantity and fodder quality, stover from some high yielding popular hybrids is at par or even better value with the best sorghum stover traded. Sorghum stover, the above-ground biomass left after grain harvest, supports much of the urban and near-urban dairy production in peninsular India.

Between 130 and 200 tons of sorghum stover are sold daily in the fodder markets of Hyderabad alone. Some of the stover is transported several hundred kilometers and costs, on a dryweight basis, about 50% of the price of sorghum grain, which is up from 20 to 30% just 15 years ago. Sorghum stover’s high monetary value can be explained by India’s demand for sorghum fodder, and possibly to a decline in the area of sorghum planted. The crop has been replaced with maize in some regions. Dairy farmers and fodder traders in India generally think maize stover is less suitable than sorghum stover as livestock feed. To challenge the negative perceptions about maize stover, maize stover of a popular high-yielding hybrid with high-quality stover fodder was provided to a commercial dairy producer in the state of Andhra Pradesh.

Rastrojo-de-maíz2 This dairy producer had maintained his eight improved Murrah buffaloes on a diet typical of that of urban and near-urban dairy systems in peninsular India. It consisted of 60% sorghum stover and 40% a homemade concentrate mix of 15% wheat bran, 54% cotton seed cake, and 31% husks and hulls from threshed pigeon-pea. Each of the dairy producer’s buffaloes consumed about 9.5 kg of sorghum stover and 6.5 kg of the concentrate mix per day and produced an average of 8.9 kg of milk per day. This dairy producer purchased sorghum stover at 6.3 Indian rupees (Rs) per kilogram. Together with the cost for concentrates, his feed cost totalled 18.2 Rs per kg of milk while his sale price was 28 Rs per kg of milk. In this trial, the dairy farmer purchased maize stover at 3.8 Rs per kg. When he substituted sorghum stover with maize stover, his average yield increased from 8.9 to 9.4 kg of milk per buffalo per day while his overall feed costs decreased from 18.2 to 14.5 Rs per kg of milk per day. The substitution of sorghum stover with maize increased his profits from 3.7 Rs per kg of milk, apart from an additional 0.5kg milk per buffalo.

This study demonstrated the big potential benefits for India’s smallholder rainfed maize and dairy farmers of adopting dual-purpose, food-and-feed maize cultivars, which combine high grain yield with high fodder quality. In this way, farmers can help solve the problem of fodder scarcity while increasing the benefits of their maize cropping. “Poultry and animal feed has been the major driver for unprecedented increase in demand of maize in South & Southeast Asia. The dual-purpose maize, with high stover quality along with high grain yield, is emerging as another big driver that can further add in the increasing demand for maize in this region” says CIMMYT Maize Breeder P.H. Zaidi, who is actively collaborating with ILRI-Hyderabad, India.

CSISA scientists address farmers’ concerns on Direct Seeded Rice method in Haryana
The Dry Direct Seeded Rice (DSR) method is gaining popularity in north India, thanks to the researchers, agricultural departments, and enterprising farmers of Punjab and Haryana who have made efforts to implement it on a large scale. Faced with the threats of depleting groundwater, shortage of farm labor, rising production costs, and climate variability, more and more farmers are adopting this alternative method of sowing rice. It promises to be both environmentally friendly and cost efficient.

Compared to the more widely used method where seeds are first germinated in a nursery and then the rice seedlings are manually transplanted to the fields, DSR involves sowing seeds directly in the fields with the help of a machine called a Multi Crop Planter. This technique has been popular in some developed countries of the world, including the U.S., but is new for farmers in India. The Ministry of Agriculture of the Government of India has been promoting this technique through its two flagship schemes, the National Food Security Mission (NFSM) and Rashtriya Krishi Vikas Yojna (RKVY). DSR brings many benefits to farmers—it reduces cultivation costs by 5,100 rupees (78 USD) per hectare, reduces water consumption by 25%, and increases profitability up to 4,600 (70 USD) rupees per hectare. “Moreover, when wheat is grown after a crop of DSR, wheat productivity has been found 8 to 10% higher than when grown after a crop of conventional cultivated rice,” says Virender Kumar from CSISA.

Reports find DSR effective in reducing emissions of methane, a potent greenhouse gas responsible for global warming. CCAFS and Greenhouse Gas Emission quantification project are studying the benefits of conservation agricultural practices, like zero tillage DSR, on greenhouse gas emissions. “For each tonne of rice production with conservation agriculture based management practices, on average 400 kg CO2 equivalent was reduced compared to conventional puddled transplanted rice,” says ML Jat from CCAFS.

Haryana promotes direct seeded paddy
The State Agriculture Department, Haryana Agricultural University, and Farmers Commission are now promoting the use of DSR in Haryana because of its benefits. Four years ago, only 226 hectares of area was under DRS in Haryana. This number has increased to 8000 hectares in 2012 and is targeted to cover 20,000 hectares in 2013. However, access to effective weed management and cost-effective herbicides still remain a challenge and will affect the success of this technology in the long term.

As with any new technique, the phase of building awareness, training and responding to farmers’ concerns is integral to making DSR technique successful. Cereal Systems Initiative for South Asia (CSISA), a project funded by Bill & Melinda Gates Foundation and USAID along with other stakeholders, launched a campaign in May to encourage farmers to adopt DSR in Haryana. The campaign included technical trainings on DSR for farmers and service providers, meetings with different stakeholders to identify and solve the problems of availability of inputs including machinery and seed, mass-media programs like radio talks, and distribution of pamphlets in the local language. The campaign reached the farmer at the field and village level for their direct feedback and to understand their problems. “Synergy between different public-private stakeholders, feedback from farmers, and technical inputs to the farmers at the right time are necessary after a series of intensive trainings to make a transformation like Direct Seeded Rice technology a success,” says B.R. Kamboj from CSISA. CSISA, in collaboration with IFC-Dunar Foods Limited and the Haryana State Department of Agriculture, organized a travelling seminar on 14 August in different villages of the Asandh block of the Karnal district. Farmers highlighted their concerns, which included late availability of the subsidized inputs such as seeds, herbicides, and machinery, and weed problems even after the proper application of herbicides.

Responding to various issues, representatives from the organizations suggested the application of preemergence herbicide, which prevent the germination of weed seeds such as pendimethalin, is necessary for effective weed management in DSR; on machinery, farmers could establish farmer cooperatives and pool resources to purchase the machinery; on less germination, sowing should be done by the expert service providers. It is also critical to use the proper setting of the sowing depth of the machine. The participants also visited the DSR fields of different villages including Balla, Salwan, Dupedi, and Padhana. While the crops looked very healthy, symptoms of zinc deficiency and excessive use of urea were seen. B. R. Kamboj demonstrated how to identify the weeds and advised on judicious use of pesticides for effective control of insects, diseases, and weeds. To ensure a good harvest from the DSR fields, the next step is timely control of insects and pests. Farmers must learn to identify the insect and pests and the right stage to control them. The Department of Agriculture will provide regular visits and trainings on insect pest management (IPM) in some identified DSR villages. “This will be a very important activity to build the confidence in the farmers to continue using DSR technique,” Kamboj says.

Are mobile phones helping farmers?

mobile-phones2 Mobile phones promise new opportunities for reaching farmers with agricultural information, but are their potential fully utilized? CIMMYT’s agricultural economist Surabhi Mittal and IRRI’s economist Mamta Mehar argue that institutional and infrastructural constraints do not allow farmers to take full advantage of this technology. In India, agro-advisory service providers use text and voice messaging along with various mobile phone based applications to provide information about weather, market prices, policies, government schemes, and new technologies. Some service providers, such as IKSL, have reached more than 1.3 million farmers across 18 states of India. But what is the real impact of such services? Are messages available at the right time? Do they create awareness? Do they strengthen farmers’ capability to make informed decisions? Are they relevant to his or her farming context?

Mittal and Mehar say there is still a long way to go. While farmers get information through their mobile phones, it is often general information irrespective of their location and crops, which is information they cannot effectively utilize. In 2011, CIMMYT conducted a survey with 1,200 farmers in the Indo-Gangetic Plains; the survey revealed the farmers needed information on how to address pest attacks and what varieties better adapt to changing climatic conditions. Instead, they received standard prescriptions on input use and general seed varietal recommendations. To provide the information farmers really need, dynamic databases with farmers’ land size, cropping pattern, soil type, geographical location, types of inputs used, variety of seed used, and irrigation must be developed.

Sustainability is another problem. Such agro-advisory projects require continued financial assistance; when money runs out, the project ends and the people are again left without information, feeling cheated and without trust for any similar project that may come in the future. There is a need to assess the willingness of farmers to pay for these services and develop sustainable business models, say Mittal and Mehar. Furthermore, it has been shown that the benefits of mobile phone services are not reaching the poor, as they do not have access to the technology despite its increasing availability. The main beneficiaries of the mobile phone revolution are the ones with skills and infrastructure, and the poor are thus left even further behind.

mobile-phones What can be done? Agro-advisory providers need to develop specific, appropriate, and timely content and update it as often as necessary. This cannot be achieved without a thorough assessment of farmers’ needs and their continuous evaluation. To ensure timeliness and accuracy of the provided information, two-way communication is necessary; Mittal and Mehar suggest the creation of helplines to provide customized solutions and enable feedback from farmers. The information delivery must be led by demand, not driven by supply. However, even when all that is done, it must be remembered that merely receiving messages over the phone does not motivate farmers to start using this information. The services have to be supplemented with demonstration of new technologies on farmers’ fields and through field trials.
