Theme: Capacity development

CIMMYT training courses play a critical role in helping international researchers meet national food security and resource conservation goals. By sharing knowledge to build communities of agricultural knowledge in less developed countries, CIMMYT empowers researchers to aid farmers. In turn, these farmers help ensure sustainable food security. In contrast to formal academic training in plant breeding and agronomy, CIMMYT training activities are hands-on and highly specialized. Trainees from Africa, Asia and Latin America benefit from the data assembled and handled in a global research program. Alumni of CIMMYT courses often become a significant force for agricultural change in their countries.

Jelle Van Loon’s workshop in the fields at El Batán is all about experimentation. The CIMMYT engineer from Belgium is making affordable and efficient tools for smallholder farmers in Mexico by innovating technology and adapting what is already available. Van Loon, leader of smart mechanization for the conservation agriculture program in Mexico, works within the Take it to the Farmer component of MasAgro, or the Sustainable Modernization of Traditional Agriculture. MasAgro focuses on sustainable farming practices and new technology to help farmers increase their maize and wheat yields.

Van Loon and his team design and produce machinery specifically suited for conditions in Mexico. That might mean adding fertilizer and seed bins to a 2-wheel tractor, modifying hand planters from China and Brazil or adapting a machine to be able to plant seeds for large or small grains. “This is going to be awesome,” Van Loon said while looking at a prototype of a shovel with seed and fertilizer boxes attached. One of the other tools his team is working with – a hand planter that deposits fertilizer and seed – was featured, along with Van Loon, in a Voice of America news article last month.

Van Loon, who came to CIMMYT in October 2012, has a background in agriculture and engineering and has worked throughout Latin America. Development is “in his blood,” he said, because his grandfather was a farmer and his parents worked in the Congo. He first came to Latin America as a teenager when he studied in Honduras as part of an exchange program. “I stayed a lot longer than I was supposed to,” said Van Loon, who also researched in Peru while working on his master’s degree. The chance to return to his “Latin roots” motivated Van Loon to apply for the smart mechanization position at CIMMYT. He said he has driven tractors since he was 10 years old and fixed motorcycles since he was 16, which helped him learn quickly on the job.

Many of the machines Van Loon and his team adapt are already used elsewhere in the world, but small changes or additions can make them more effective in Mexico or useful for multiple crops. By adding a water pump to a tractor, for example, or offering a variety of discs for a plow, machines can be more efficient. New tools are first designed using SolidWorks, a 3D modeling computer program. Implements are then stress-tested in the field to see how useful they are in local conditions. The team works with local blacksmiths so machines can be made and repaired in the area.

Throughout the process, Van Loon is in touch with the farmers who could benefit from his team’s work. “We see what they want to achieve and make it align with conservation agriculture principles,” he said. His team produces information sheets on the tools as well as plans that anyone can download and print, with the goal of making the innovations readily available. Van Loon said he spends about half of his time in the office and the other half in the field. MasAgro has hubs throughout Mexico, sometimes allowing him to ride his motorcycle nearly 1,700 kilometers to Ciudad Obregón, Sonora. He also explains his work to visitors, who can see the improved machines on display at a hangar at El Batán.

It takes collaboration to help farmers improve their maize and wheat yields, Van Loon said. His team is focused on the latter two-thirds of the “good seeds, good tools and good practices” equation farmers need to succeed. “We want to create a smart smallholder farmer,” Van Loon said.

Wheat research is an intriguing story to many. CIMMYT’s Global Wheat Program (GWP) keeps germplasm flowing worldwide, and more than 100 wheat researchers and 40 junior scientists and graduate students attend its annual wheat improvement course. The program hosted students from around the world in 2013, introducing them to the program’s critically important work.

Visit to wheat research station at Ciudad Obregón

The GWP hosted a visit from 10 to 11 April for 50 children, ages 8 to 12, who are part of the PERAJ program at the Instituto Tecnológico de Sonora (ITSON). The university’s “adopt a friend” program encourages students to tutor children from public primary schools in Ciudad Obregon. The CIMMYT visit originated from the daughter-mother link of Carolina Rivera Amado, a Ph.D. student in the MasAgro program, and Alma Amado Quintana, the PERAJ coordinator at ITSON. Alma Amado said the program creates relationships between the tutors and their “adopted” students to support education and strengthen the professional and personal development of ITSON students. The children and their tutors were intrigued by the diversity of wheat. They learned the source of their favorite wheat tortillas and discovered the work scientists do to increase wheat productivity. The experience allowed Mathew Reynolds and colleagues Araceli Torres, Carolina Rivera, Arnauld Thiry and Perla Chávez to explain how plants grow and for Amor Yahyaoui to explain how scientists ensure the production of healthy plants.

Yokohama City University (YCU) students visit CIMMYT headquarters

Seven undergraduate students came to CIMMYT’s headquarters from Japan’s Yokohama City University (YCU) from 6 to 7 August to tour facilities and interact with wheat and maize scientists. The overall objective of the visit was to expose the students to international agricultural research on crop improvement and to give them an opportunity to meet worldleaders in research helping to feed the world. Through the efforts of Tomohiro Ban, a former CIMMYT scientist who is a lead researcher at the Kihara Institute for Biological Research (KIBR) and his working relationship with wheat scientist Ravi Singh, young undergraduates from Japan visit CIMMYT almost every year. CIMMYT scientists who interacted with the group included Singh, Jose Juan Caballero, Sehgal Deepmala, Bibiana Espinosa, Velu Govindan, Julio Huerta, Masahiro Kishii, Aleksandre Loladze, Monica Mezzalama, Henry Ngugi, Tom Payne, Pawan Singh, Sukhwinder Singh, Prashant Vikram, He Xinyao and Amor Yahyaoui. The students were introduced to CIMMYT’s global maize and wheat research programs as well as training activities in the fields of breeding and genetics, pathology, biotechnology, seeds of discovery and bio-fortification research. The visit to the new Bioscience Complex showed the students the steps in wheat variety development from DNA analysis to field plot techniques. “I learned about the importance of connecting biotechnology and breeding,” said Yuki Kajita, a student participating in the visit. “I had a very good time at CIMMYT. I hope to come again someday as a researcher.”

Tokyo university students visit CIMMYT

Tokyo University of Agriculture also organized a visit to CIMMYT headquarters. On 12 August, a group of 12 students visited as part of their tour abroad to agricultural research institutions and to learn about agricultural activities of smallholder farmers in Mexico. The students toured the gene bank and learned about seed selection and treatment as part of CIMMYT’s international nursery activities. They also visited wheat and maize demonstration plots and were encouraged to consider CIMMYT as they continue with their post-graduate research. The group was headed by Mariko Kawaminami, agronomist and professor at the University of Chapingo. This tour is organized and hosted by the University of Chapingo every year as part of its international academic exchange activities.

Afghanistan capacity development supported by Japanese Institutions

Representatives from several institutions working on the Development of Wheat Breeding Materials for Sustainable Food Production (SATREPS) project visited CIMMYT on 28 February to encourage support for young Afghan scientists and capacity development of young Japanese researchers and students. SATREPS aims to train Afghan scientists in the development of wheat breeding materials for sustainable food production through partnerships with Afghanistan, Japan and Mexico. Japanese institutions involved in the project include KIBR, Yokohama City University, the Science and Technology Agency (JST) and the Japan International Cooperation Agency (JICA). The project also sponsored two Afghan scientists to join the CIMMYT Global Wheat Program wheat improvement course in Ciudad Obregón from March to May. Lead scientists in breeding, physiology, pathology and biotechnology helped participants to acquire practical experience in wheat breeding. Zahery Eid Mohammad and Ahmadi S. Hasibullah completed the training and are registered for master’s studies at Yokohama City University. CIMMYT will continue to strengthen the Japan-Mexico collaboration by training young Afghan scientists and encouraging young Japanese students to get involved in agricultural research.

ICAR-CIMMYT organize training in molecular tools in wheat

By Arun Joshi, CIMMYT

Twenty young scientists from India and Nepal learned about existing and up-and-coming wheat breeding tools during a training program last month. Continuing earlier training programs initiated during the last few wheat crop cycles in India, the Global Wheat Program in South Asia organized the three-day “ICAR-CIMMYT Molecular Breeding Course in Wheat” from 25 to 27 August. It took place at the Directorate of Wheat Research (DWR) of the Indian Council of Agricultural Research in Karnal.

ICAR-CIMMYT The training was for young scientists from different wheat research stations of India involved in a BMZ-funded project to increase the productivity of wheat under rising temperatures and water scarcity in South Asia. The training program attendees’ enhanced understanding of existing molecular tools for wheat breeding as well as emerging tools such as genomic selection. “Molecular tools will play an increasing role in wheat breeding to meet challenges in coming decades,” said Indu Sharma, director of DWR in Karnal. The program covered both theory and practice on the use of molecular makers in wheat breeding, especially those related to vernalization, photoperiodism and earliness per se, which could be used to enhance early heat tolerance. Practical sessions in the molecular laboratory of DWR focused on extraction of DNA, quantification and quality control of DNA, polymerase chain reaction polymerase chain reaction amplification and electrophoresis.

During various sessions, the instructors explained the steps of molecular tools to be used for such work. The participants tested their new scoring skills during an exercise which involved scoring the bands and cross-verifying results. Laboratory procedures on safety were also explained. CIMMYT wheat breeder Arun Joshi and Vinod Tiwari, principal scientist and principal investigator of crop improvement for DWR in Karnal, coordinated the training under the WHEAT CRP Strategic Initiative 6 (enhanced heat and drought tolerance). Indian resource participants included Ratan Tiwari, P.K. Gupta, Vinod Tiwari and a team of molecular scientists including Rajender Singh, Rekha Malik, Sonia Sheoran and Pradeep Sharma from DWR, Karnal. The CIMMYT scientists involved were Susanne Dreisigacker and Arun Joshi while the practical lessons were organized and led by Tiwari and Dreisigacker. A laboratory manual “ICAR-CIMMYT molecular breeding course in wheat” was also developed for the course, which was later released in the All India Wheat and Barley Workers meeting.

Mexico: early adopters of MasAgro technologies show their achievements

Masagro2 Husband-and-wife duo Oscar Hernández Mendoza and Rosa Elena Montiel Díaz said their work with MasAgro helps them improve the lives of farmers in their town. The two made a presentation about their efforts in Úrsulo Galván, Veracruz, on 29 August during CIMMYT’s first symposium for MasAgro experimental platforms. MasAgro, or the Sustainable Modernization of Traditional Agriculture, is a CIMMYT program coordinated with Mexico’s Ministry of Agriculture, Livestock, Rural Development, Fisheries, and Food (SAGARPA).

MasAgro aims to help small-scale farmers implement sustainable farming practices and introduce new technology to help increase their maize and wheat yields. The symposium brought together more than 50 collaborators from different parts of Mexico who are working with MasAgro to increase sustainability, improve yield and lower costs for small-scale farmers. Attendees at the El Batán event saw posters on the various projects and talked with the collaborators about their results. “It has been an opportunity for them to exchange their work,” said Yesenia Soto, who works in training for MasAgro. Posters explained outcomes and future plans from Morelos, Oaxaca, Sonora and Yucatán and other states with crops ranging from maize and wheat to chia and beans. Hernández and Montiel, founders of Grupo Hernádez Montiel, are working with MasAgro to bring new technology to their region and raise maize yields by training farmers. So far, the group has been successful in helping farmers produce more, Hernández said. “We can’t work alone,” he said. “It’s for our people, our producers.”

Masagro1 Jesús Rafael Valenzuela Borbón came to the symposium from Navojoa, in southern Sonora. He is trying to bring conservation agriculture practices to farmers in an area where the main problem is a lack of water. Valenzuela is in charge of an experimental site where he is growing maize and wheat using crop rotation. Use of such practices in the area is minimal, though Valenzuela is looking for support to implement them more widely, he explained. “All of the results are very favorable,” he said.

MasAgro trainees evaluate maize quality and improve tortilla production

Tortilla5 Mexico is the fifth highest maize-consuming country in the world. It is also the number one consumer of maize for food, given that its population eats 70 percent of available maize grain every year. The national food maize groups included in this percentage can be divided into three main types: home consumption, the nixtamalized flour industry and the maize dough and tortilla industry. Businesses in the latter sector must supply maize grain of uniform quality so that maize processing will be more efficient, stable and profitable. With this in mind, 30 Mexican dough and tortilla manufacturers, grain marketers and seed producers attended a practical training course entitled “Maize Grain Quality and Technology” given by researchers from the Sustainable Modernization of Traditional Agriculture (MasAgro) initiative from 2 to 3 September in the Cereals Laboratory of the School of Agroindustrial Engineering of the Autonomous University of Chapingo (UACh).

Representatives from UACh, the National Forestry, Agricultural, and Livestock Research Institute (INIFAP) and CIMMYT studied the effects that physical, structural and chemical grain characteristics have on tortilla appearance and the tortilla-making process. Course participants tried several simple methods for evaluating grain quality and the efficiency of tortilla making. They also did some very basic testing to determine the quality of the tortillas they made. “By using these lab techniques and processing maize grain with different textures and colors, and seeing the difference it makes in the appearance, texture and color of the tortillas, I acquired the tools I need to evaluate the grain I buy for my business,” said one of the participants. “Up to now, I’ve constantly been adjusting the process and mixing different types of grain and I always get the same quality, but sometimes I don’t get it right and I lose a lot of money.”

Tortilla1 After exchanging their experiences, businessmen, grain merchants and seed producers showed interest in revising Mexican Regulation (Norma Mexicana) 034-1 on grain quality to make the range of values match the current dough- and tortilla-making process. In their opinion, the different links of the maize production chain are increasingly demanding when it comes to the raw materials, processes and products they use. For this reason, Gricelda Vázquez of INIFAP’s Valley of Mexico Experiment Station (CEVAMEX) thinks continued collaboration among research and industrial institutions is needed to ensure that research results extend beyond the production process. As David Tecotl pointed out, “Only by attending these courses at the university do we acquire firsthand knowledge of these important alternatives.” He and his fellow trainees tested the best techniques for mixing nixtamalized flour (of bean, barley, oat, amaranth, and maize) to make more nutritionally rich tortillas, as did the UACh students who are doing their Ph.D. research under the supervision of Ofelia Buendía, one of the course organizers.

Pathology Research Greenhouse opened in Ankara, Turkey, honors researcher

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

A new greenhouse opened at the Central Field Crop Research Institute in Ankara, Turkey, honoring Senior Pathologist Lutfi Cetin for his contribution to wheat pathology research. The new, state-of-the-art greenhouse allows independent work on yellow, leaf, and stem rust throughout the year. The greenhouse has three sections—one for each of the rusts studied—and can maintain its temperature throughout winter frosts and hot summers. Its construction was supported by the Ministry of Food, Agriculture and Livestock of Turkey, FAO, and IFAD. Turquía

The pathogen collected in June of this year has been already multiplied in the greenhouse. The pathology group of the Central Field Crop Research Institute represents one of the few labs in the region dealing with rust at all stages and plays important role in research, breeding, and training. A half-day workshop was held on 27 August 2013 at the institute to recognize Mr. Cetin’s contributions.
Mr. Cetin started his wheat carrier more than 30 years ago and has been closely associated with the International Winter Wheat Improvement Program (Turkey-CIMMYT-ICARDA) in developing yellow rust resistant germplasm for the past 20 years. In the mid-1990s, when the cooperative work started, the frequency of yellow rust resistant entries did not exceed 20 to 30%. The pathology screening field with artificial inoculation was established in Haymana near Ankara with reliable and heavy infection by yellow and other rusts. This work later developed into broader rust pathology research including monitoring, pathotype identification, and screening in the seedling stage. The pathology group now annually evaluates 6,000 to 8,000 lines and populations from IWWIP in the field and around 1,000 in the seedling stage.

CIMMYT sets the stage for a CONACYT partnership

Written by on September 12, 2013. Posted in News.

CIMMYT will explore potential partnership opportunities with the research centers of Mexico’s National Science and Technology Council (CONACYT), which specialize in exact and natural sciences and technological development. At least six of these centers focus on areas of interest to CIMMYT, explained Inocencio Higuera, Associate Director of CONACYT’s 27 research centers, during a visit to CIMMYT Headquarters on 30 August 2013. Of the 27 centers, the Food and Development Research Center (CIAD), the Scientific Research Institute of Yucatan (CICY), the Center for Innovative Applied Research on Competitive Technologies (CIATEC), and the Ecology Institute (INECOL) have projects on crop pathology, production and nutrition systems, and other areas of agricultural research. Higuera also pointed out MasAgro activities could contribute to Mexico’s National Food Initiative (INSAM), which seeks to increase the production and availability of basic food staples through natural resource conservation and sustainable agriculture. CONACYT2

“In principle, CONACYT and CIMMYT could work together to design a postgraduate course that would place Mexico on the cutting edge of training and research targeting the exploration and use of crop genetic resources,” said Marianne Bänziger, CIMMYT’s Deputy Director General for Research and Partnerships. “CIMMYT could also develop collaborative research projects for assessing maize grain quality and nutritional value with CONACYT centers working on enhancing grain productivity.” In this way, CIMMYT has set the stage for establishing a partnership that would allow it to pursue these and other opportunities with CONACYT

Training on weed control in direct seeded rice will boost farmers’ confidence

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.

Mathematical models could further CIMMYT’s reach

Written by on September 9, 2013. Posted in Features.

Mathematical models could boost CIMMYT’s impact on Mexico, a leading scientist in the United States said last month. Carlos Castillo-Chavez, a Mexican-born scientist and professor at Arizona State University, visited El Batán from 21 to 23 August to meet with the staff of the MasAgro program and the Biometrics and Statistics Unit. His trip focused on learning about and giving input on CIMMYT programs as well as seeking opportunities for collaboration with ASU.

Castillo-Chavez is part of U.S. President Barack Obama’s Committee on the National Medal of Science, whose members help select medal candidates from among top U.S. scientists. Castillo-Chavez grew up in Mexico City with interests in theater and literature but thought he would be more successful pursuing math. He moved to the United States in 1974 and worked odd jobs before starting college in Wisconsin and later earning a PhD in mathematics from the University of Wisconsin- Madison. He first visited CIMMYT about two decades ago and was the PhD adviser at Cornell University for Carlos Hernández, the head of CIMMYT’s Biometrics and Statistics Unit. Castillo-Chavez’s research focuses on the intersection between math, natural sciences, and social sciences. He studies disease evolution and social landscapes, including tuberculosis and SARS, the role of mass transit systems in the spread of influenza in Mexico, and “social diseases” such as drinking and drug use. Castillo- Chavez founded the Mathematical, Computational and Modeling Sciences Center at ASU and has received various awards at the national level for his research, teaching, and mentorship of minority students.

Bringing research to the people it could benefit is often a complicated and political process, Castillo- Chavez said. Scientists have the responsibility to communicate their research to the public, but policymakers set the course for “trendy” research topics. It’s an issue that needs to change, he said. And it could change with more interdisciplinary programs that have direct ties to and benefits for society. “Most problems of interest to Mexico don’t always apply to what’s current or hot in international academia,” Castillo- Chavez said. “There is no reason why Mexico should not have its own research agenda that may or may not intersect with the U.S.” He said during the visit that his research on contagion and how information spreads applies to the work CIMMYT is doing. Mathematical models can be used to study and increase the impact CIMMYT’s research has on Mexico by assessing the culture and identifying obstacles, he said. By communicating the research to enough people, “a culture change takes place where farmers and politicians are in constant communication to implement CIMMYT research,” Castillo- Chavez said. ASU and CIMMYT’s Biometrics and Statistics Unit could collaborate on this research by mentoring and training young people who would work closely with both institutions, he said, adding that he’s interested in exploring those possibilities.

During his visit, Castillo-Chavez learned MasAgro is an example of a project that targets a local population, he said. But the challenge with all advancements is finding the right leaders to put them into place. “It’s clear the research could generate dramatic improvements if implemented,” he said. “Nationally, we would see incredible advances in sustainable agriculture.”

Strengthening maize technicians’ capacity in Mozambique

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

Maize technicians received a training course in Mozambique.

Forty participants from various agricultural research stations, private seed companies, and communitybased seed production schemes attended a training course for maize technicians during 8–12 July in Chimoio, Mozambique.

The objective of the course was to update maize technical staff on seed production and implementation of on-station and on-farm trials. The training included practical sessions as well as theoretical lectures on seed production, breeding for biotic and abiotic stresses, and trial lay-out using the alpha lattice design.

The course was organized under the auspices of Drought Tolerant Maize for Africa (DTMA), Sustainable Intensification of Maize-Legume Systems for the Eastern and Southern Africa (SIMLESA), and USAID Mozambique in collaboration with the Instituto de Investigação Agrária de Moçambique (IIAM). During the course, SIMLESA representatives emphasized on-farm testing using the mother baby trial and the principles of conservation agriculture. USAID-Mozambique and DTMA focused on the importance of producing quality seed and scaling up seed to reach smallholder farmers.

Mozambique has recently released two drought tolerant maize hybrids and one early maturing open pollinated variety (OPV) under the DTMA project. With very few seed companies in the country, most of the seed in Mozambique is sourced from the informal seed sector. The training session came at a crucial stage, as several communities are ready to begin production of newly released OPVs. The course was coordinated by Peter Setimela and Cosmos Magorokosho from CIMMYT-Zimbabwe, and David Mariote and Pedro Fato from IIAM.

Learning to breed insect-resistant maize at CIMMYT-Kenya

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

“The trip was an eye opener for me. We have no mass rearing facility in Ethiopia; neither do we practice artificial infestation of stem borers. We only undertake natural infestation for our trials, which does not give uniform infestation, leading us to wrong conclusions,” said Midekssa Ardessa from Bako Agricultural Research Center at the Ethiopian Institute of Agricultural Research (EIAR), who visited CIMMYT-Kenya during 21-27 July 2013 with a team of scientists from Ethiopia, Uganda, Tanzania, and Mozambique, to gain hands-on experience in breeding insect-resistant maize. “We are now very knowledgeable on mass rearing of stem borers and on running an insectary after our visit and practical sessions at the CIMMYT Katumani Insectary,” added Abiy Dibaba from EIAR’s Melkasa Agricultural Research Center. “At the CIMMYT Kiboko Postharvest Lab, we learned a lot about maize weevils and the larger grain borer, and how to screen maize for resistance against these postharvest pests.”

The visit, organized and facilitated by the Insect Resistant Maize for Africa (IRMA III Conventional) and the Water Efficient Maize for Africa (WEMA) projects, aimed to build capacity in maize breeding for insect resistance using conventional approaches, insect resistance screening, and management of field and lab infestations. Participants came from EIAR; Kenya Agricultural Research Institute (KARI); Selian Agricultural Research Institute (SARI), Tanzania; National Biological Control Program, Tanzania; Ministry of Agriculture, Tanzania; National Crops Resources Research Institute (NACRRI) of the National Agricultural Research Organization (NARO), Uganda; and National Institute of Agronomic Research (IIAM), Mozambique.

“The visit provided an opportunity for the scientists to understand IRMA’s and WEMA’s research work in Kenya and a forum to share experiences in mass rearing, breeding, and pest control among participating countries,” said Stephen Mugo, CIMMYT principal scientist/maize breeder and IRMA and WEMA projects coordinator. It is also a learning process for CIMMYT scientists, he added. The team visited CIMMYT insect pests resistant germplasm nurseries and trials at the Embu, Kirinyaga University College, and Kiboko sites where they learned how to set up, infest, manage, and take data on stem borer trials and nurseries. At the KARI-Katumani IRMA III Conventional collaborative stem borer mass rearing facilities, participants learned to set up, equip, and manage stem borer mass rearing; in Kiboko they focused on the set up, management, and data collection for storage pests screening. The field and lab practical sessions were facilitated by CIMMYT scientist/entomologist Tadele Tefera.

The annual IRMA project’s program has trained more than 50 scientists since its inception in 2009. “Most of us talk very easily and confidently about insect rearing. However, it is quite a challenge when we engage in the practical aspects,” said Tefera. “What we have exposed you to is just a tip of the iceberg in the business of mass rearing of insects. There is still a lot to learn, much of it by yourself as you engage in the practical aspects of it.” The participants appreciated the effort taken by the organizers. One of them, Egas Nhamucho of IIAM, said: “Infestation of maize with stem borers was a real learning point for me, a real delicate task of picking out very tiny 10 insect larvae, ensuring that you do not pierce and kill them with the camel brush, and carefully and strategically placing them on each maize plant. The practical sessions really made me appreciate some of the tasks we have always taken for granted.”

Concluding the event, CIMMYT scientist/maize breeder Yoseph Beyene called on the participating scientists to ensure that as many people as possible get access to the knowledge they gained. “Invest in people to effectively and successfully undertake your research,” he said.

WEMA project manager Sylvester Oikeh thanked CIMMYT scientists for the support they provided to the Ugandan team in setting up the Namulonge Insectary. “I am looking forward to other countries emulating Uganda and setting up their insectaries,” Oikeh added.

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.”

CIMMYT-CCAFS modeling team discusses gender in Ethiopia

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.

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
