Focus on heat stress resilient maize for Asia

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

HTMA-meeting Scientists from the Heat Stress Tolerant Maize for Asia (HTMA) project and representatives from collaborating public and private sector institutions from the region, Purdue University, and CIMMYT gathered together during 30-31 July 2013 in Kathmandu, Nepal, for the 1st HTMA Annual Progress Review and Planning Meeting. The meeting was jointly organized by the National Maize Research Program (NMRP) and CIMMYT to discuss progress to-date and future HTMA work plans. HTMA, supported by USAID under the Feed the Future initiative, is a public-private alliance targeting resource-poor people in South Asia who rely on growing maize for subsistence or income in rainfed conditions and whose welfare is directly dependent on maize yields and negatively affected by crop failures.

K.B. Koirala, National Maize Coordinator for Nepal, welcomed all participants and highlighted the importance of the public-private alliance through HTMA, especially for addressing such complex issues as developing and distributing heat stress resilient maize. CIMMYT Global Maize Program director B.M. Prasanna reiterated the need for and importance of maize breeding for heat-stress resilience in his opening remarks, while USAID’s Larry Beach stressed the project’s significance in addressing the emerging effects of climate change.

The first day was devoted to an annual progress review, which was initiated by senior maize physiologist and CIMMYT and HTMA project leader P.H. Zaidi, who presented updates on the project execution and status of progress during the project’s first year. The following session, chaired by Nepal Agricultural Research Council (NARC) executive director D.B. Gurung, covered membrane lipid profiling in relation to heat stress; identifying quantitative trait loci (QTL) for heat-stress tolerance and component traits by joint linkage analysis; association mapping for heat tolerance; latest marker statistics on genotyping-by-sequencing; genomic selection for heat stress tolerance; and development of target populations for rapid-cycle genomic selection. The afternoon session was chaired by Pakistan Agricultural Research Council (PARC) chairman Iftikhar Ahmad and focused on phenotyping for heat-stress tolerance; crop modeling and the IMPACT model component; a road map for development and distribution of heat resilient maize; seed distribution systems; and seed companies’ perspectives on target markets.

During day two, participants discussed and developed a workplan and activities for the second year of the project for each collaborating institution. This was followed by a special session on “Exploring linkages & synergy among USAID-funded projects in South Asia.” Representatives from various ongoing projects in the region, including the Hill Maize Research Project (HMRP), Cereal System Initiative for South Asia (CSISA), and HTMA, as well as NARC and the Nepalese Ministry of Agriculture, joined in the lively discussion, which helped to identify opportunities for potential linkages among the region’s initiatives and a synergy between them. The linkages could offer a win-win situation for all stakeholders.

The meeting was concluded with an HTMA project steering committee meeting chaired by B.M. Prasanna. The committee members expressed their satisfaction with the strategy, ongoing activities, and the progress being made.

Impressive adoption of metal silos in western Kenya

Written by on August 13, 2013. Posted in Features.

metal-silos1 “When Richard Pamo, the then Caritas Development Coordinator [Homa Bay] introduced the metal silo technology to me in 2008, I felt I had received the solution to my perennial problems of storing my grains, particularly maize that was prone to weevil attack,” said Bishop Philip Anyolo of the Catholic Diocese of Homa Bay, Kenya, to a visiting team from the Effective Grain Storage for Sustainable Livelihoods of African Farmers Project (EGSP-II). “I instantly ordered two silos, of 1- and 1.8-ton capacity. And I have never been disappointed. I was so satisfied with the ability of the metal silos to protect my maize against weevils that I acquired another 720-kg capacity metal silo for my mother in 2009.”

The Bishop, who was among the first people to use metal silos after the project introduction in Kenya, noted how widely appreciated the technology has become: “Since I acquired the metal silos, word about its effectiveness has spread within and beyond my home county of Bungoma, which was not even in the project target area. Like in Homa Bay, farmers there are making all efforts to acquire the metal silos.” And it is not just the farmers who use the technology these days; Rose Owanda in the poultry business has acquired six 2.7-ton capacity metal silos. “I intend to be buying grains from the market during times of glut. This will not only ensure that I buy the grains at the lowest prices, I am assured of enough grain for making the feeds for the birds throughout the year.” The success of the silo has also created brisk business for trained metal silo artisans who are receiving orders from beyond the Homa Bay County.

metal-silos2 Impressed with the technology, the Bishop has advised all schools and institutions sponsored by the Catholic Church in Homa Bay to acquire metal silos for grain storage. His advice has since caught the attention of other institutions, including St. Vincent De Paul Boys Boarding School in Kisii County who acquired seven 2.7-ton metal silos in December 2011 after the Nyambururu Teachers College, Kisii County, bought ten 1.8-ton silos earlier in the year; the College had learned of the technology from the Kokwaro Secondary School in Homa Bay Diocese who had acquired eight 2.7-ton silos in 2010. Since the launch of EGSP-II in October 2012 in Kenya, Homa Bay farmers have acquired 230 metal silos, and institutions in the area, particularly boarding schools and colleges, have bought 47 more, according to Beautrice Otieno, Livelihoods Program Manager at Caritas Homa Bay and the site coordinator for western Kenya.

metal-silos3 “Production is all in vain if farmers cannot store the harvested produce. Effective storage is even more critical at these times of climate change, where the associated weather vagaries adversely affect production. Whatever little that we produce should be well managed, and that includes being well stored for use at the desired time,” stressed Jennifer Ndege, Chief Officer, Agriculture, Livestock and Fisheries at Homa Bay County. Tadele Tefera, CIMMYT entomologist and EGSP-II coordinator, agrees: “A lot of agencies focus on increasing productivity but very few on the management of what has been harvested. Yet this is a very important aspect in any food security chain.” The information was collected during an assessment tour of Homa Bay and surrounding counties conducted by the EGSP-II Kenyan team during 15-19 July 2013; the team consisted of Tefera, Isaac Mutabai (CIMMYT), Wandera Ojanji (CIMMYT science writer/editor), Zachary Gitonga (CIMMYT Socioeconomics Program research associate), Addis Teshome (CIMMYT entomologist), Jackson K. Njana (Caritas-Embu), Everastus Okumu (Caritas-Homa Bay director), Otieno, Paddy Likhayo (Kenya Agricultural Research Institute, KARI), and Kimondo Mutambuki (KARI and EGSP-II Kenya national coordinator).

Making villages ‘climate smart’

Written by on August 13, 2013. Posted in News.

“Climatic extremes and variability are becoming more frequent and resulting in losses for farmers. This issue cannot be addressed in isolation; it needs collective participation of all stakeholders, at all levels,” stated Clare Stirling, leader of the CIMMYT component of the Climate Change, Agriculture and Food Security (CCAFS) CRP, at a stakeholder consultation on ‘Climate Smart Agricultural Technologies for Smallholder Farmers of Bihar’ held on 22 July 2013.

The talks were organized by CIMMYT and BISA, under the aegis of CCAFS, and in collaboration with national research and extension partners such as the Indian Council of Agricultural Research (ICAR), Indian Agricultural Research Institute (IARI), Rajendra Agriculture University, the State Department of Agriculture, and the Government of Bihar; international centers Bioversity International, the International Water Management Institute, and the International Food Policy Research Institute; local NGO and private sector partners; and farmer groups of the Climate Smart Village (CSV) clusters, Vaishali district, Bihar.

The lively discussions included almost 200 participants, including innovative CSV farmers from Bhatthadasi, Rajapakar, and Mukundpur (Vaishali district); agriculture advisors from various Village Panchayats; climate smart farmer groups, research students, and local service providers. M.L. Jat, CIMMYT-CCAFS South Asia Leader, explained the concept of CCAFS CSVs in South Asia, and the key climate smart activities they are implementing for the benefit of smallholder farmers in Bihar’s Vaishali district. Participants visited demonstration plots where R.K. Jat, CIMMYT-BISA Cropping Systems Agronomist, showed how mechanization and conservation agriculture-based management practices are being implemented even on small, fragmented land holdings. By effectively ‘pooling’ their land for operational purposes, farmers have improved efficiency, reduced costs, and established timely crop management even with uncertain rainfall. R.K. Jat also explained the main advantages of the key climate smart interventions such as zero tillage, Direct Seeded Rice (DSR), raised bed planting, residue management, crop diversification, and nutrient management in managing climate risks and optimizing resources for higher profitability for the smallholders.

The active participation of about 80 female farmers allowed for a balanced and varied consultation. All the farmers expressed their concerns regarding climate variability and how it is affecting their livelihoods. They shared their experiences of turning their villages into CSVs, and how the new practices have benefitted them; after planting their wheat under zero till in the winter of 2012-13, farmers were initially skeptical of these changes to age-old practices, but having now reaped higher yields with less input costs, all the farmers have committed to planting under zero tillage next season. DSR has also been recently introduced, and the farmers thought the technology seemed promising in that it would reduce cultivation costs and provide some security under the increasing uncertainties of rainfall and labor shortages. The women farmers praised the intoduction of the ZT machine by CIMMYT under CCAFS. With many men migrating to cities, the women highlighted the reduced labor load with the increased availability of machinery and bed planting of maize and legumes.

I.S. Solanki, IARI Regional Station Head, emphasized the need for farmers to work with scientists in adopting resilient farm technologies and locally-adapted seed. This was reiterated by Stirling: “The concept of CSVs is just one example of making synergies among different programs, investments, institutions, and stakeholders, for adaptation, risk management, and mitigation of climate change effects,” she said.

Wheat-for-Africa gains momentum

Written by on August 2, 2013. Posted in News.

Wheat-for-Africa Wheat was not a traditional staple in much of Africa, but urbanization, a growing middle class, and changing lifestyles are driving a rapid increase in demand for it. The urban and rural poor in Africa eat wheat, as do more prosperous consumers, and demand is burgeoning with rising populations. But leading wheat producing countries in Africa grow enough to meet at most 40% of their demand, so the continent imports more than US$ 15 billion-worth of grain each year.

Efforts to put wheat on the food and trade agenda in Africa recently came together at the Forum for Agricultural Research in Africa (FARA) meeting in Accra during 15–20 July 2013, when senior research, development, and policy experts met with representatives of CGIAR’s WHEAT research program to develop a strategy for promoting African wheat production. “The idea is to put together all the actors—the production side, the legislation, the demand and markets,” said Victor Kommerell, manager of the CIMMYT-led WHEAT Program. “Initially the strategy should focus on gathering more evidence of production and market potential, particularly regarding smallholder farmers’ chances to grow wheat as a cash crop, and then looking at future consumption and regional trade.”

The connections made at FARA in July followed the release of a key study in late 2012 at the ground-breaking conference Wheat for Food Security in Africa in Addis Ababa. Shortly after that conference, African Union agriculture ministers endorsed wheat as a strategic crop for Africa. Their heads of government, at African Union level, endorsed this a few months later.

“As a rough-and-ready estimate, most countries are fulfilling less than a quarter of their wheat production potential,” said CIMMYT socioeconomist Bekele Shiferaw, a key author of the wheat study. “There are many opportunities both to expand the area devoted to wheat and to increase yields from existing acreage.”

According to Shiferaw, this will require a fundamental change in the way participants look at the entire wheat value chain—from farm to market and from government office to donor boardroom. More research is needed on potential constraints on improved wheat production, including issues related to markets, land, labor, and how food aid is distributed.

Challenges affecting farming at different scales in different country contexts must be carefully considered—from small farms’ lack of mechanization, labor, and access to markets, to problems that have undermined large-scale wheat farming projects in Africa in the past. The aim is to ensure the best mix of small, medium, and large farms, as well as fitting options to the differing conditions of high- versus low-population density nations and current highland wheat-growing areas. The 2012 study focused on rainfed wheat, according to Kommerell. Irrigated wheat also has great potential—and unique challenges—in Africa. Release of a report by WHEAT on irrigated wheat for Africa is planned for September 2013.

Metal silos: a timely intervention in curbing postharvest losses

Written by on August 2, 2013. Posted in News.

Metal-silos The metal silo technology promoted by CIMMYT for maize storage has been hailed in Kenya as the ultimate solution to high maize postharvest losses caused by the maize weevil (Sitophilus zeamais) and large grain borer (Prostephanus truncatus), two major destructive insects of stored maize causing 30% losses and more than 80% damage to stored maize in Kenya and other countries in sub-Saharan Africa. The real losses are even bigger: when considering their environmental impact, the subsequent losses in nutritional value, industrial input, market opportunities, and the possible adverse effects on health of populations consuming poor-quality products, the need for interventions becomes even more apparent and pressing. “Addressing waste across the entire food chain must therefore be a critical pillar of future national food strategies,” said Ngari Nyaga, Crop Post Harvest Division head at the Kenyan Ministry of Agriculture, during the official opening of a national Stakeholders Workshop on Effective Grain Storage for Sustainable Livelihoods of African Farmers Project (EGSP-II) held in Nakuru, Kenya, on 28 June 2013.

Tadele Tefera, CIMMYT entomologist and EGSP-II coordinator, outlined the workshop objectives: provide a forum to exchange ideas, information, and research outputs on EGSP-II among stakeholders in Kenya; raise awareness on postharvest losses and dissemination of effective grain storage technologies among stakeholders; consult stakeholders on policy environment and market issues for the purpose of refining, updating, and implementing EGSP-II; engage in policy dialogue on matters related to storage; find means of enhancing the technology adoption; and acquaint key stakeholders in the country with the technology and how they could enhance its adoption among the farmers they are supporting through their activities.

With the annual average production of about 33 million 90-kilogram bags, postharvest losses of about 20% translate into 540 million kilograms. “The metal silo technology being promoted by CIMMYT is a timely and critical element in the quest to promote food security,” stated Nyaga, pointing out that about two million Kenyans are considered food insecure. The technology will “lower postharvest losses, assist farmers to save on dusting labor, have healthy and tradable grains, and allow the farmers to wait for better prices instead of selling immediately after harvest for fear of losing their grains to weevils, larger grain borer, and poor storage.” The technology will also help to address an issue recently reported in a Ministry of Agriculture survey: the incorrect use of pesticides. According to Nyaga, metal silos will “lead to zero usage of storage pesticides, hence result in better health and stoppage of illegal use of restricted pesticides by farmers.”

As other forms of storage – traditional granaries and sisal and gunny bags – have proven ineffective, and chemical control unsuccessful (only half of Kenyan maize farmers use storage pesticides), Nyaga welcomed the decision of Kenya, Uganda, Tanzania, Rwanda, and Burundi to work together to develop technologies and policies to reduce crop postharvest losses in the region.

The workshop gave stakeholders a chance to update themselves on the project, appreciate the magnitude of the postharvest losses and the effectiveness of alternative postharvest technologies being used, and better understand the economics of postharvest management. It also provided the latest news from onstation trials on metal silo technology and super grain bags.

Tefera thanked the Swiss Agency for Development and Cooperation for funding EGSP II, a project aiming to reduce postharvest losses, enhance food security, and improve incomes of resource-poor farmers in Kenya.

Nitrogen-use-efficient maize ready for release in Africa

Written by on August 1, 2013. Posted in News.

Bish-cropped Big news for public and private maize breeders and seed providers in Africa: you can now test your lines and hybrids under controlled stress conditions that allow you to tell how they’ll perform when grown by farmers. The latest results from regional maize stress screening trials and other important topics formed the agenda of the annual meeting of the Improved Maize for African Soils (IMAS) project, which during 10-12 July 2013 drew more than 70 participants to its Nairobi venue, including representatives from CIMMYT, which leads the project, key partners DuPont Pioneer, the Kenya Agricultural Research Institute (KARI) and South Africa’s Agricultural Research Council (ARC), from African seed companies, from organizations like One Acre Fund, and from project funder the Bill & Melinda Gates Foundation.

“There’s been great interest from private companies to test their germplasm in our regional trials,” said acting project lead and CIMMYT maize breeder Biswanath Das, who cited the project’s stress screening networks as an unprecedented achievement in the region. “The 2012-13 trials included 114 maize lines and hybrids from 13 partners, including 6 companies, that were tested at 40 locations region-wide. Trial environments include nitrogen-depleted soils and controlled drought stress, closely replicating actual farm conditions.”

After water, nitrogen is the single most important input for maize production; lack of it is the principal constraint to cereal yields in Africa, in areas with adequate rainfall. An illustration of that importance, this photo shows the very different response of the same maize variety to zero versus 80 kilograms of nitrogen fertilizer on an experiment station plot.

In the most recent results, yields of elite hybrids from the project match or marginally surpass those of the best widely-grown commercial hybrids in favorable circumstances, while significantly out-yielding them under drought and low-nitrogen conditions, according to trial coordinator and CIMMYT breeder Amsal Tarekegne. “We expect that, through this network, all seed available to farmers will eventually feature higher yields under all conditions that farmers face.”

Launched in February 2010, IMAS is developing maize varieties that better capture the small amount of fertilizer African farmers can afford, and that use the nitrogen more efficiently to produce grain. The project is using molecular markers and transgenic approaches to augment conventional breeding. The varieties are Africa-adapted and will feature added traits like drought tolerance, disease resistance, and preferred grain quality.

Conventionally bred IMAS-derived maize seed is near ready for national testing, certification, and release. Discussions and efforts now center around how best to spread awareness among seed providers and farmers and how to market seed. Meeting participants visited several Kenya field sites, including KARI’s Kiboko research station, where in partnership with KARI, the Bill & Melinda Gates Foundation and CIMMYT are supporting construction of a maize doubled haploid breeding facility expected to be operational in late 2013. Recently recruited CIMMYT molecular geneticist Michael Olsen, who is taking up coordination of IMAS, thanked everyone for the warm welcome he’d received. “I’m really excited about working in this project,” he said. “The energy coming from the meeting was tremendous.”

Project oversight committee members, Zimbabwean researcher Idah Sithole-Niang and retired maize physiologist Greg Edmeades, as well as Bill & Melinda Gates Foundation program officer Gary Atlin, expressed their pleasure at the progress to date. “Low productivity due to poor soil fertility is the greatest challenge to African agriculture,” said Atlin. “Breeding is one way to address this. Thanks for your superb efforts.”

Stepping up the fight against maize lethal necrosis in Eastern Africa

Written by on August 1, 2013. Posted in News.

MLN-Eastern-Africa1 “I can now identify with accuracy plants affected with maize lethal necrotic disease,” stated Regina Tende, PhD student attached to CIMMYT, after attending the CIMMYT-Kenya Agricultural Research Institute (KARI) “Identification and Management of Maize Lethal Necrosis” workshop in Narok, Kenya, during 30 June-3 July 2013. This was not the case a few weeks ago when Tende, who is also a senior research officer at KARI-Katumani, received leaf samples from a farmer for maize lethal necrosis (MLN) verification.

Tende is one of many scientists and technicians who experienced difficulty in differentiating MLN from other diseases or abiotic stresses with similar symptoms. According to Stephen Mugo, CIMMYT Global Maize Program (GMP) principal scientist and organizer of the workshop, this difficulty encouraged CIMMYT and KARI to organize this event to raise awareness about MLN among scientists, technicians, and skilled field staff; provide training on MLN diagnosis especially at field nurseries, trials, and seed production fields; train on MLN severity scoring to improve the quality of data generation in screening trials; and introduce MLN management in field screening sites to scientists, technicians, and skilled staff. The workshop brought together over 80 scientists and technicians from CIMMYT, KARI, and other national agricultural research systems (NARS) partners from Tanzania, Uganda, Rwanda, and Zimbabwe.

“It is important that all the people on the ground, particularly the technicians who interact daily with the plants and supervise research activities at the stations, understand the disease, are able to systematically scout for it, and have the ability to spot it out from similar symptomatic diseases and conditions like nutrient deficiency,” stated GMP director B.M. Prasanna.

Proper and timely identification of the MLN disease, which is a pre-requisite for effective control, is not easy. CIMMYT maize breeder Biswanath Das explains: “First of all, the disease is caused by a combination of two viruses, Maize chlorotic mottle virus (MCMV) and Sugarcane mosaic virus (SCMV). Secondly, its symptoms –severe mottling of leaves, dead heart, stunted growth (shortened internode distance), leaf necrosis, sterility, poor seed set, shriveled seeds– are not always unique to MLN but could be due to other fungal diseases and abiotic conditions.” The training workshop was one of CIMMYT/KARI initiatives to combat the disease threatening all the gains made so far in maize breeding. “With nearly 99% of the commercial maize varieties so far released in Kenya being susceptible to MLN, it is important that institutions like CIMMYT and KARI, in strong collaboration with the seed sector, develop and deploy MLN disease resistant varieties in an accelerated manner,” stated Prasanna. One of the key initiatives in this fight is the establishment of a centralized MLN screening facility under artificial inoculation for Eastern Africa at the KARI Livestock Research Farm in Naivasha. Plans are also underway to establish a network of MLN testing sites (under natural disease pressure) in the region to evaluate promising materials from artificial inoculation trials in Naivasha. The state of the art maize doubled haploid (DH) facility currently under construction in Kiboko will also play a crucial role in accelerating MLN resistant germplasm development. “The DH technology, in combination with molecular markers, can help reduce by half the time taken for developing MLN resistant versions of existing elite susceptible lines,” stated Prasanna.

MLN-Eastern-Africa2 During his opening speech, Joseph Ng’etich, deputy director of Crop Protection, Ministry of Agriculture, noted that about 26,000 hectares of maize in Kenya were affected in 2012, resulting in an estimated loss of 56,730 tons, valued at approximately US$ 23.5 million. Seed producers also lost significant acreages of pre-basic seed in 2012: Agriseed lost 10 acres in Narok; Kenya Seed lost 75; and Monsanto 20 at Migtyo farm in Baringo, according to Dickson Ligeyo, KARI senior research officer and head of Maize Working Group in Kenya.

While this loss represents only 1.7%, Ligeyo assured everyone that Kenya is not taking any chances and has come up with a raft of measures and recommendations: farmers in areas where rainfall is all year round or maize is produced under irrigation are advised to plant maize only once a year; local quarantine has been enforced and farmers are to remove all infected materials from the fields and stop all movement of green maize from affected to non-affected areas; seed companies must ensure that seeds are treated with appropriate seed dressers at recommended rates, they must also promote good agricultural practices, crop diversification, and rotation with non-cereal crops.

Throughout the workshop, participants learned about theoretical aspects of MLN, such as the disease dynamics, management of MLN trials and nurseries, and identification of germplasm for resistance to MLN. They also participated in practical sessions on artificial inoculation, and identification and scoring. Several CIMMYT scientists played an active role in organizing the workshop, including breeders Stephen Mugo, Biswanath Das, Yoseph Beyene, and Lewis Machida; entomologist Tadele Tefera; and seed systems specialist Mosisa Regasa. They were accompanied by KARI scientist Bramwel Wanjala, KEPHIS regulatory officer Florence Munguti, and NARS maize research leaders Claver Ngaboyisonga (Rwanda), Dickson Ligeyo (Kenya), Julius Serumaga (Uganda), and Kheri Kitenge (Tanzania). During his closing remarks, KARI Food Crops program officer Raphael Ngigi, on behalf of KARI director, urged participants to rigorously implement what they had learnt during the workshop in their respective countries or Kenya regions to help combat MLN at both research farms and farmers’ fields.

Commenting on the usefulness of the workshop, technical officer at KARI-Embu Fred Manyara stated: “I will no longer say I do not know or I am not sure, when confronted by a farmer’s question on MLN.”

“You go to the field.” U.S. Borlaug Fellows in Global Food Security

Written by on August 1, 2013. Posted in News.

When asked how you become a successful wheat breeder, Dr. Norman E. Borlaug replied, “Well, you go to the field. You go to the field again, and then you go to the field. When the wheat plants start to talk to you, you know you have made it.” The Nobel Peace Prize, the Congressional Gold Medal, and the Presidential Medal of Freedom were awarded to Dr. Borlaug for saving the lives of over one billion through his efforts. Borlaug’s legacy continues today through the U.S. Borlaug Fellows in Global Food Security Program at the Center for Global Food Security, Purdue University, providing graduate students the opportunity to “go to the field” and become successful scientists in their own right.

Funded by USAID, the Borlaug Fellowship provides graduate students the opportunity to collaborate with agricultural scientists in developing nations. The program fosters connections between scientists internationally, while furthering research and developing community around important agricultural themes, such as production, natural resource conservation, and development. With a focus on interdisciplinary and cross-cultural experiences, students benefit from the ability to practice their science on the ground in an international setting, preparing them to become important members of the global scientific community. Doctoral candidates Ariel N. Rivers of Pennsylvania State University and Sean M. Thompson of Texas A&M University were given the opportunity to “go to the field” during the 2013 field season in partnership with CIMMYT.

Of the dual-title program, Entomology and International Agriculture and Development at Pennsylvania State University, Rivers (pictured above) is mid-way through her six-month tenure at CIMMYT’s El Batán station. By studying the three practices of conservation agriculture —crop rotation, minimal soil disturbance, and retention of crop residues on the soil surface— Rivers hopes to better understand which of these practices augment beneficial insect communities and how. In high enough numbers, beneficial insects can contribute to pest control, nutrient cycling, and soil aeration, all of which are essential to agricultural production in low-input developing country agriculture.

Thompson (pictured right), of the Department of Soil and Crop Sciences at Texas A&M University, is working with Ground Penetrating Radar (GPR) to non-destructively assess wheat root biomass. This technology could allow for rapid, non-destructive assessment of populations and selection for traits undetectable by traditional methods. The primary objective of this research is to define the capability of GPR to phenotype below ground crop biomass, in the context of higher yield and quality stability in wheat during drought stress. GPR is one of the many field-based high-throughput phenotyping technologies being tested in CIMMYT’s Wheat Physiology program.

Both Rivers and Thompson plan to collaborate internationally after they complete their doctoral studies. “We have benefitted from the opportunity to practice that skill at CIMMYT,” they both agree. “Thanks to the example set by Borlaug, we are better prepared to take our science ‘to the field’.” Further information about the research or the U.S. Borlaug Fellowship in Global Food Security can be obtained by contacting the Purdue Center for Global Food Security.

CIMMYT-CCAFS modeling team discusses gender in Ethiopia

Written by on July 29, 2013. Posted in News.

Exploring the potential for integrating gender at a range of scales in the work of the CIMMYT-CCAFS modeling team, members of the team accompanied by colleagues from the International Water Management Institute (IWMI) gathered in Addis Ababa, Ethiopia, on 4 July 2013 for a half-day explanatory CIMMYT-CCAFS Gender and Modeling Workshop. The workshop was organized by gender consultant Cathy Farnworth as part of a wider drive to bring gender into CIMMYT-CCAFS work.

The workshop began with a series of presentations, first of which was by IWMI hydrologist Tracy Baker. Baker focused on ‘Incorporating gender and other perceptions into physically based modeling environments,’ emphasizing that incorporating gender into modeling was part of a wider need to integrate the complexities of human nature into models. Gender incorporation can improve models because women and men use landscapes in different ways, Baker stressed, pointing out Participatory Geographic Information System (PGIS) modeling as one option that may offer insights into gendered uses of landscape. Baker demonstrated gendered uses and perceptions of landscape through a case study of her own work in Kenya, in which she showed that women and men use the same landscape in very different ways.

CIMMYT climate economist Songporne Tongruksawattana discussed ‘Gender issues in farm household modeling’ describing a typical household model and the challenges climate change poses for intra-household decision-making.

CIMMYT’s crop modeler and GIS specialist Kindie Tesfaye presented work on ‘Biophysical and economic modeling at scale,’ conducted by himself, Sika Gbegbelegbe, Uran Chung, and Kai Sonder, and focused on simulating climate change impacts and scenarios and the role of promising technologies at different spatial and temporal scales. He concluded his presentation by listing pertinent questions on the opportunities and challenges of incorporating gender into biophysical and economic modeling.

CIMMYT’s agricultural anthropologist Michael Misiko’s work was titled ‘Handling gender issues in agriculture: A tricky balance between biophysical and social facets’, and examined how mechanization in conjunction with the promotion of conservation agriculture (CA) exposes gender relations in farming systems and can lead to both opportunities and new inequalities between women and men. He pointed out that while machines and tools are not gendered and can be used equally by women and men, in practice women are frequently not able to take advantage of machinery. From a purely technical point of view CA should be ideal for women, since it should minimize drudgery, particularly weeding, but in reality women’s tasks are often hard to mechanize due to their intrinsic nature, women’s often small and scattered plots, and because women are not a target priority group for mechanization by extension agents.

The workshop continued with a group discussion led by Baker. Issues raised and discussed included: How to ask the right questions at the right scale? How can we combine PGIS derived maps created by women/men and different ethnic communities? Whose voices are prioritized? Who participates and why? Who decides who participates? Whose reality are you trying to capture?

Participants then discussed ways forward and agreed to create a gender and modeling taskforce and a cross-CGIAR forum for discussion and engagement; they hope to follow up with another, larger-scale, workshop in 2014. Later, CIMMYT-CCAFS modeling team members discussed how to strengthen gender in their work plans.

Research battles wheat spot blotch disease

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

wheat-spot-blotch-disease After screening some 500 wheat lines and varieties at 6 sites in Bangladesh, India, and Nepal, a group of scientists were able to identify 35 genotypes that resist spot blotch. This is the number-one disease of wheat in the Eastern Gangetic Plains, seriously damaging the crops of farmers—who are mostly smallholders—on some 9 million hectares.

The results were reported at a meeting of participants in two projects of WHEAT, the CGIAR Research Program on this crop, at Mohanpur Campus of IISER-Kolkata, India, on 24 June 2013. Funded through multi-year competitive grants from WHEAT, the two project are “Deciphering phytohormone signaling in modulation of resistance to spot blotch disease for identification of novel resistance components for wheat improvement,” led by Shree P. Pandey, IISER-Kolkata, and “Spot blotch of wheat: Delivering resistant wheat lines and diagnostic and molecular markers for resistance,” led by Ramesh Chand of Banaras Hindu University, Varanasi. Among other things, participants discussed year-one outcomes and laid plans for the coming crop cycle.

Chand reported on the seedling stage resistance found in the wheat tested. In this type of resistance, the pathogen is present on wheat seedlings for up to 25 days without any infection, exhibiting responses such as lesion mimic and tissue necrosis, which appear to attenuate pathogen effects. The resistance gene Sr2 was also found in most of the resistant seed.

Exciting moments in the meeting were the discussions of biochemical and histo-pathological parameters and their possible integration in the resistance screening. Pandey and his team reported novel research to understand phytohormone signals that regulate wheat’s resistance against Bipolaris sorokiniana–the causal pathogen of spot blotch—and which are synthesized in response to the pathogen’s attack. The IISER group is assembling a dictionary of signaling genes that can serve as genomic tools for resistance breeding in wheat. “Expression of these DNA ‘words’ changes when plants are attacked by the spot blotch pathogen,” said Pandey. “Deciphering this word choice can elucidate the chain of command in plants in to the pathogen, helping breeders to design plants better-equipped with resistance genes.”

Finally, there was a report on the field performance of the 500 lines at two other locations, UBKV Coochbehar and RAU Pusa.

In addition to the scientists mentioned above, participants included WHEAT manager Victor Komerell; CIMMYT researcher Arun Joshi; Prof. V.K. Mishra, BHU, Varanasi; Prof. Apurba Chowdhury; Dr. P.M. Bhattacharya, UBKV; and Dr. Rajiv Kumar, Rajendra Agricultural University, Pusa, Bihar; as well as other wheat researchers from IISER-K.

“The partners here submitted separate proposals for the projects,” said Komerell. “This meeting furnishes an example of how WHEAT has encouraged them to collaborate.”

CIMMYT/CCAFS in India: Gender, action, research

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

In June 2013, ML Jat (Global Conservation Agriculture Program) and research teams in Bihar and Haryana, India, welcomed CIMMYT gender specialist Tina Beuchelt and gender consultant Cathy Farnworth to discuss integration of gender perspectives into their daily research routine. The visit was triggered by the request from the CRP on Climate Change, Agriculture and Food Security (CCAFS) to enhance women’s access to and use of agricultural and climate-related services and information (IDO5).

The visit began with discussions held with individual researchers on how to include a gender perspective in their work plans and field experiments, demonstration plots, out-scaling efforts, and surveys. The team visited farmers participating in CIMMYT/CCAFS projects in Bihar and Haryana, where lively small group discussions helped the visitors to gain a deeper understanding of the situation of women and men, their roles and responsibilities, and gender-related constraints existing in their small-scale farming systems. The team met with smallholder and better-off farmers, as well as landless workers and female-headed households to obtain a representative picture of those involved in agriculture in CIMMYT/CCAFS target areas. Men and women were interviewed separately, and CIMMYT staff helped to explain the production systems and the basket of climate-smart farming options currently available, and shared their thoughts on how to respond to specific gender challenges.

Given the varying agro-ecological environments and socioeconomic characteristics of farmers in each state, it was agreed that in order to address IDO5 successfully, new partners, new allies, and new ideas are needed. While the discussions proceeded well, one of the female participants made a timely and heart-felt warning: “You ask us to take risks, but where will you be if we fail?”

The trip culminated with a workshop on “Pathways of gender-equity led climate-smart farming: learning from stakeholders” organized jointly by the Directorate of Wheat Research (DWR), the Indian Council of Agricultural Research (ICAR), and CIMMYT/CCAFS in Haryana on 7 June 2013. A wonderful mix of male and female farmers; farmer organizations; researchers from ICAR, Haryana Agricultural University, and CGIAR; extension and developmental organizations, including the State Department of Agriculture, NGOs; private sector organizations; and politicians – about 65 participants in total – joined the workshop and contributed with great enthusiasm to discussions on advantages and disadvantages of different climate-smart technologies for women, more effective types of institutional support required to support women etc. Participants then formed small groups to discuss concrete ideas for action to support women in agriculture, which was followed by presentations and discussions in a plenary session chaired by DRW director Indu Sharma.

The workshop was concluded with dinner wherein Suresh Gahalawat, Deputy Director for Agriculture in Karnal at the Government of Haryana, who had showed great enthusiasm regarding the topic during the workshop, announced that: “Gender will become part of the agricultural policies of Haryana”. “To start with, we will include the gender component in all schemes operated in the district,” he added, confirming the importance and success of the workshop.

The Indian research team is strongly committed to integrating gender into their research activities

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

Course-on-remote-sensing-using-an-unmanned-aerial-vehicle Training on the use of remote sensing from an unmanned aerial vehicle was given at INIAP-Peru’s Vista Florida experiment station on 1-5 June 2013. The course was organized by INIAP, the University of Barcelona, Spain, and CIMMYT’s regional office in Colombia. Remote sensing is used in precision agriculture and for phenotyping crops that are important for the region, such as maize, rice, and sugar cane.

Course participants included 44 representatives from the International Potato Center (CIP), the University of Talca (Chile), INIA-Peru, and Peru’s Ministry of Agriculture, among other institutions. The course is one of several activities sponsored by the “Affordable field-based HTPPs” project led by José Luis Araus of the Department of Plant Biology of the University of Barcelona and funded by CRP MAIZE. During the event, a phenotyping platform developed within the framework of the project was presented to INIA.

The director of the Vista Florida station, Miguel Monsalve Aita, opened the course, which was given by distinguished academics and scientists such as José Luis Araus; Pablo Zarco and Alberto Hornero from the Sustainable Agriculture Institute, Córdoba, Spain; Antón Hernández, president of AirElectronics, Madrid, Spain; Carlos Poblete, Claudio Balbotín, and Gustavo Lobos from the University of Talca, Chile; Hildo MacLean and Susan Palacios from CIP, and Luis Narro from CIMMYT’s Global Maize Program.

The lectures focused on topics such as applying remote sensing in phenotyping; spectral and thermal remote sensing of stress from unmanned aircraft; image and data processing; use of software to process the gathered information; and thermal image analysis for diagnosing drought stress and controlling irrigation. In addition, Hildo MacLean showed how the Oktokopter–XL works. Luis Narro demostrated how to use the new version of the GreenSeeker for making recommendations on N application in maize and, Antón Hernández showed how the unmanned aircraft Sky Walker, which comes equipped with a flight programmer, an infrared camera, and a multispectral camera for collecting data, works. The aircraft used in the demonstration was donated to the Vista Florida station as part of the project’s contributions.

Another essential part of the course was the intensive training on subjects such as platform management, flight programming, and downloading and processing information that was provided to a group of technicians from INIA and private seed companies. Also, Given that INIA technicians who are in charge of the platform need to become thoroughly familiar with it, three technicians from Vista Florida will go to Spain in September to take a course on processing and interpreting images.

The course organizers wish to express their appreciation to the Vista Florida Maize Program.

Investigation plot of hybrid seed production technology in Puerto Vallarta, Jalisco, Mexico.

Mexican seed producers and researchers who participate in the Sustainable Modernization of Traditional Agriculture (MasAgro) initiative met recently at El Cantón, a location close to Puerto Vallarta, Jalisco, Mexico, where experimental plots aimed at producing high quality and higher yielding hybrid maize seed are planted.

“The purpose of these experimental plots is to adapt the best production technologies to three mega-environments (highland valleys, tropics, and subtropics), observe the performance of seed targeted for agricultural areas where MasAgro operates, and identify new locations where hybrid maize seed with high physical and genetic quality can be produced,” explained Félix San Vicente, leader of the maize component of MasAgro.

This strategy aims to coordinate the development and multiplication of hybrid maize seed adapted to rainfed areas that are a priority for MasAgro, as well as to promote its adoption among medium- and small-scale maize farmers.

People attending the field day received information on the yield of maize hybrids developed by participants in MasAgro’s Network of Seed Sector Members and Cooperators, which includes 35 Mexican seed companies and agricultural research institutes. Both white and yellow hybrids were presented––seven for highland valleys, five for the tropics, and four for the subtropics. The seeds were derived from simple and triple crosses that have higher adaptation and yield capacity. The materials presented are at the pre-commercial stage, but most are already available to seed companies that belong to the network.

CIMMYT researchers explained that the objective is to endow seed currently being improved using conventional breeding methods with key agronomic traits such as adaptation capacity, high yield, days to flowering, and staggered sowing in order to better synchronize flowering.

Members of the MasAgro network hope to increase the hybrid

maize seed production area in the 2013 fall-winter cycle, thanks to the high adaptation capacity and good performance shown by materials developed for tropical, subtropical, and highland valley production areas targeted by MasAgro.

Also attending the event were representatives of 23 Mexican seed companies, as well as researchers from Mexico’s National Forestry, Agricultural, and Livestock Research Institute (INIFAP) and academics from the Southern Regional University Center of Chapingo Autonomous University (UACh).

Bekeles-Ethiopia The third Dialogue on Ethiopian Agricultural Development: Agricultural Research for National Development in the Face of Climate Change and Food Security was held during 4-5 July 2013 at the Haramaya University of Agriculture, Haramaya Harar. The Dialogue aimed to provide a platform for discussion on agricultural research for development and transformation of the sector for food security in Ethiopia.

The Dialogue was attended by World Food Prize Laureate and distinguished professor Gebissa Ejeta; two members of the agricultural standing committee of the Ethiopian parliament; alumni of the Haramaya University working at various national, regional, and international top-level positions, such as Berhane Gebrekidan, Sime Debela, Zemedu Worku, Ephirem Mamo, and Solomon Bekure; senior staff of Haramaya, Jimma, Hawassa, Dire Dawa, and Mekele universities; members of USAID’s Capacity to Improve Agriculture and Food Security (CIAFS); representatives of the Ethiopian Institute of Agricultural Research (EIAR); the Ethiopian Seed Enterprise; CIMMYT; and ILRI.

Panel discussions covered 60 years of agricultural research in Ethiopia; agricultural research at regional institutes and Ethiopian universities; perspectives of users of technologies generated by the national agricultural research system (NARS); linking research at international levels with NARS for greater impact; the Ethiopian experience; presentations on contributions of agricultural research in Ethiopia in terms of food security, foreign earnings, and climate change adaptation; reflections on dialogues and issues deserving special attention; and recommendations for enhancing efficiency and productivity of NARS.

Three CIMMYT scientists –Drought Tolerant Maize for Africa project leader Tsedeke Abate, Bekele Shiferaw from the Socioeconomics Program, and Bekele Abeyo from the Global Wheat Program– presented during the panel discussions. The presentations were followed by a Q&A session, during which CIMMYT was named as top-rated CG center in Ethiopia due to its contributions, along with other institutions and centers, to national agricultural education, research for development, and extension with outputs and impacts. CIMMYT was commended by the current and former EIAR directors general and deputy director general, as well as Haramaya University senior alumni and political representatives, for its long-standing relations and close collaborative work with the NARS in generating technologies, strengthening national capacities, and reaching farmers.

As the meeting assessed the gaps and constraints of agriculture for development, ways forward, and future continuity of the dialogue, Abeyo assured the participants that “CIMMYT is committed to continue and maintain its high-quality contributions to Ethiopia.”

Tracking the adoption patterns in maize and legume farming system in Ethiopia

DSC_5826_Group-photo-900x4001 Myths and cultural practices can block farmers’ acceptance of a new technology, particularly the principles of reduced tillage, residue retention, and cropping rotations that underlie conservation agriculture. This was one observation in a recent visit to farmers in four districts in Ethiopia by Australian International Food Security Centre (AIFSC) director, Mellissa Wood, and AIFSC Biosecurity and Food Safety Manager, Dennis Bittisnich.

Farmers in one village who continued intensive tilling instead of conservation agriculture said that tillage helps control crop diseases. Many Ethiopian farmers also keep livestock, so crop residues have higher value as fodder for cows than as cover for soils. “Maize stover is also used as fuel for cooking fires,” said CIMMYT socioeconomist Menale Kassie, who is also regional leader for the project Adoption Pathways to Sustainable Intensification in Eastern and Southern Africa. “Understanding the constraints and incentives affecting adoption is crucial, if innovations are to be relevant for farmers.”

The four-year adoption pathways project is funded by AIFSC, managed by the Australian

Centre for International Agricultural Research (ACIAR), and led by CIMMYT, in collaboration with national universities and research institutes in Ethiopia, Kenya, Malawi, Mozambique, and Tanzania; the University of Queensland, Australia; the Norwegian University of Life Sciences; and the International Food Policy Research Institute (IFPRI).

According to Menale, the project is closely linked to the Sustainable Intensification of Maize-Legume Systems for Food Security in East and Southern Africa (SIMLESA) program; working where SIMLESA has been promoting and testing conservation agriculture using demonstrations on farms and on national agriculture research stations.

Farmers learn from their peers, particularly early adopters and those who lend their farms to showcase the practices. Fatuma, a widowed mother of 10 and an early adopter who farms with help from her children, says reducing tillage has cut her work load. She is a role model to other farmers—a rare feat for a woman, according to village sources—and neighbors have decided to try conservation agriculture after seeing Fatuma’s crops flourish.

“The project will evaluate the data and use the rich survey information to advise on potential policy and technical interventions,” said Yirga, researcher with the Ethiopian Institute of Agriculture Research (EIAR) and country coordinator for the project. Innovative livestock management and community engagement can help, according to Chilot Yirga, as can providing alternative cattle feeds such as intercropped legume fodders, which also enrich soils by fixing nitrogen. “The way to show this is through on-farm demonstrations,” said Wood, lauding the researchers for the on-station trials and on-farm engagement. “In Australia, conservation agriculture is very important as we have a lot of drought and changing rainfall patterns; CA makes us more productive.”
