colorOrangeThe HarvestPlus Maize group examines progress toward breeding maize with enhanced pro-vitamins A, iron, and zinc.

CIMMYT maize scientists and colleagues from national programs in the key countries targeted by HarvestPlus reported significant progress in identifying maize with elevated concentrations of iron, zinc, and pro-vitamins A (chemicals the human body can convert to vitamin A) in their elite maize varieties and germplasm collections. The results of two years of work were presented at the second HarvestPlus Maize meeting hosted by EMBRAPA, the national agricultural research program of Brazil at their maize and sorghum research station in Sete Lagoas.

Maize is a key target crop for nutritional enhancement because it is so widely consumed in areas where high malnutrition—especially vitamin-A deficiency—exists. Scientists working in the HarvestPlus program hope eventually to breed high-quality, high-yielding maize with enhanced pro-vitamins A, iron, and zinc content. These micronutrients in maize will have to be in a form that survives processing and can be utilized by the human body.

The first planning meeting for the maize scientists was held in 2003 in Ethiopia. “We’ve come a long way since we first met two years ago,” says Kevin Pixley, the HarvestPlus Maize coordinator and Director of CIMMYT’s Tropical Ecosystems Program. “But we have also realized that this is a very complex subject with many assumptions that have to be validated.”

CIMMYT maize breeder Dave Beck showed the group results of screening of CIMMYT elite highland and transition zone maize germplasm for enhanced levels of pro-vitamins A, zinc, and iron. HarvestPlus nutritionists have set minimum targets for the concentrations of these micronutrients in maize. The good news is that for zinc, CIMMYT has identified material that was already above the threshold. For iron the picture is less promising as existing lines identified have only 60 percent of the required minimum level for iron. For pro-vitamins A CIMMYT has examined hundreds of lines. The best CIMMYT lines have about 75 percent of the minimum requirement, but sources identified by project partners in the USA have the minimum required level of pro-vitamins A. The CIMMYT team is now breeding to enhance pro-vitamins A concentration for highland, transition zone, mid-altitude, and lowland-adapted materials.

A topic of keen interest at the meeting was how to convince people to adopt any nutritionally enhanced maize varieties that might be developed. In much of eastern and southern Africa, white maize is preferred over yellow maize. Scientists in Zambia and Zimbabwe had conducted studies about the acceptability of yellow maize. Both studies found that yellow maize is associated with food aid and that was one reason people did not want to eat it. Scientists know there is a strong correlation between the color of the maize and the total level of carotenoids. Some of these carotenoids are precursors for vitamin A “pro-vitamins A.” Torbert Rocheford, a professor of plant genetics at the University of Illinois, suggested that the debate should not actually be about yellow maize in many parts of Africa. He said what we should be talking about is orange maize—something new that will not carry the stigma of yellow maize but will have high pro-vitamins A content.

South Asian Partners Host Trustees for Extended Field Visits

Much of CIMMYT’s research focuses on improving the livelihoods and food security of poor households in South Asia, which is home to more of the world’s poor–43 percent–than any other region. To observe the impact of CIMMYT’s efforts there and to assess opportunities to help farmers, CIMMYT’s Board of Trustees and senior management visited India and Nepal in March. Officials of both countries hosted the visiting delegation.

India and Nepal are two key partners for CIMMYT. India’s relationship with CIMMYT began before the Green Revolution, and the world has benefited from the research products of this collaboration. CIMMYT also has maintained a long partnership with Nepal, where the National Agricultural Research Center (NARC) has hosted CIMMYT’s South Asia Regional Office for 18 years.

Field Visits in India

visitingNepalOn the first day of the field visits, about 200 farmers from nearby villages greeted the delegation and expressed appreciation for new practices that were helping them to diversity agricultural production and conserve resources such as water and soil. The delegation was welcomed in Kapriwas, Gurgaon by senior officials of the Indian Council of Agricultural Research (ICAR), including Director General Mangala Rai, Deputy Director of Crops and Horticulture G. Kalloo, and M.K. Miglani, Vice Chancellor of Haryana Agricultural University. They explained how new tillage and planting practices helped Indian farmers by saving labor, fuel, and irrigation, while maintaining or increasing yields.

Many farmers were extremely enthusiastic about the visit. One farmer was sprinkle irrigating wheat that was close to maturity, which is something that is not typically done. When one of the visitors asked why he was doing this, the farmer replied that he was overjoyed by their visit and wanted to show off his sprinkle irrigation system. (The technical explanation was that he wanted to lower the heat stress and improve grain filling.)

The visitors saw research to identify salt-tolerant wheat and other crops and to study the long-term effects of saline water use at Bawal Research Station. They also saw an experiment showing how paired-row wheat planting on beds produced high yields, large spikes, and large grains, which help wheat fetch a higher market price. Although all the farmers who joined the delegation agreed that wheat planted on beds in paired rows gives higher yields with less labor and fewer inputs, they said there is a shortage of bed planters for Indian farmers. CIMMYT, ICAR, and the private sector are working to improve the situation.

Another experiment they observed evaluated the potential for growing maize in Haryana, where limited production and high demand compel people to buy maize in Delhi or Rajasthan.

On the second day the delegation visited Durgapura Research Station of Rajasthan Agricultural University. They learned about a wide spectrum of research, including breeding for resistance to rust and to cereal cyst nematode and for tolerance to saline conditions. They heard about issues related to the use of brackish and saline water in crop production in arid regions. Some participants expressed concern about the long-term health effects of this practice, especially in the production of green vegetables.

On the third day the delegation was received by farmers of Kallogarhi-Matiala Village, as well as PP Singh (Vice Chancellor, Sardar Vallabh Bhai Patel University of Agriculture and Technology, Meerut) and Larry Paulson (USAID-India). Board members were very interested in locally developed, low-cost equipment for promoting conservation agriculture. They saw the comparative performance of wheat planted using zero-tillage drills with “inverted T” and double disc openers. Farmers at this site are developing a permanent “double no-till” system of conservation agriculture to grow rice and wheat.

During dinner, representatives of Raja Balwant Singh College Trust thanked CIMMYT for more than 50 years of partnership in Indian agricultural development, dating back to before the Green Revolution. They suggested that CIMMYT and RBS, the largest and one of the oldest agricultural colleges in India, could benefit from a joint visiting scientist program.

Field Visits in Nepal

In 2003, Nepal’s national average wheat yield surpassed 2 t/ha for the first time, an achievement that gives some idea of the constraints that farmers there have overcome. The National Wheat Research Program Coordinator, Mr. M.R. Bhatta, described the impact of disease and yield nurseries that CIMMYT and NARC distribute throughout South Asia, and observed that more than 20 wheat varieties have been released in Nepal in the past 15 years.

At Khumaltar Research Station, NARC researchers highlighted studies in areas such as pathology, breeding, agronomy, soil sciences, mechanization, and biotechnology.

The visitors also heard researchers from the Hill Maize Research Project describe how communities have become self-sufficient in maize, their staple food, for the first time. Nearly 80% of Nepal’s maize is grown in the mid-hills, where more than 10 million people depend on the crop for food, income, and animal feed. Shortages are chronic. The Hill Maize Research Project provides the farmers with source seed, plus training in seed production techniques, storage, and marketing. It also ensures that there is sufficient seed of new maize varieties for farmers to replace old improved or local varieties, which yield very little.

Through their efforts, communities have produced more than 150 tons of maize seed. Community-based seed production accelerates seed replacement, disseminates new technologies, improves household food security, and raises incomes. This work, supported by the Swiss Agency for Development and Cooperation (SDC), is having an enormous impact in isolated hill sites.

A visit to farmers’ fields in Thecho Village in the Kathmandu Valley showed how farmers’ access to better wheat varieties and growing practices was increasing through participatory research. The farmers partner with NARC, CIMMYT, the University of Bangore, the Agricultural Development Organization (ADO), and others in a project funded by the UK Department for International Development. Farmers enthusiastically shared their experiences with participatory variety selection and seed production. Some groups are earning enough additional income from growing wheat to purchase new equipment or make other investments.

NARC and ADO have extended participatory variety selection to rice, legumes, vegetables, and other crops throughout Nepal after seeing the success with wheat. (In India, similar exciting work is being done in collaboration with Banaras Hindu University.)

Weighing Pros and Cons of Genetically Modified Crops in Africa

Written by on . Posted in Features.

September, 2004

Should Africa embrace genetically modified crops to help feed its hungry people? That question is explored by a recent paper entitled “Debunking the Myths of GM Crops for Africa: The Case of Bt Maize in Kenya.” The paper compares the benefits of genetically modified crops to information available on the risks, and finds that most objections are not backed by evidence. Hugo De Groote, Stephen Mugo, and David Bergvinson from CIMMYT, along with Ben Odhiambo of the Kenya Agricultural Research Institute, conducted the study, which argues for a discussion based on scientific evidence and evaluation of potential benefits against concerns.

Genetically modified crops have been successful in many countries, including Canada and the US, where they have increased yields, lowered labor and cultivation costs, and reduced the use of chemical inputs. Genetic engineering has the potential to enhance food security and nutritional quality in ways not possible with conventional technology. Because the technology is contained in the seed, it is easy to distribute to farmers. This is particularly important in Africa, where extension services have largely collapsed and transport infrastructure is poor.

Concerns about deploying genetically modified crops in Africa include food safety, ethics, environmental risk, loss of landrace biodiversity, and the lack of appropriate biosafety regulations. Although long-term effects need to be analyzed, current studies by national and international organizations reveal no demonstrated toxic or nutritionally harmful effects of foods derived from genetically modified crops.

Sounding Out Public Opinion

The study by de Groote and his colleagues focused on Kenya, where maize, the main food crop, is planted on 30% of arable lands. It drew on a variety of data sources, including participatory rural appraisals and farmer and consumer surveys. De Groote thinks it is important to make research results understandable to the general public so everyone can participate in the debate.

To gauge awareness and attitudes about genetically modified crops, the researchers interviewed 604 consumers, only half of whom were aware of them. Many appreciated the benefits but worried about potential negative effects on health and the environment, especially on local plant varieties. De Groote says consumers are increasingly aware of genetically modified food and generally accept it, but their concerns about environmental safety and biodiversity have to be addressed.

Several seed companies in Kenya have expressed interest in producing and distributing Bt maize seed, which offers an effective and practical method for reducing stem borer damage in maize. Genetically engineered Bt maize contains a gene from the soil-dwelling bacteria Bacillus thuringiensis, which produces a toxin that helps control certain pests but is not harmful to humans or livestock. The Bt gene was first introduced into the commercial maize market in 1996. It has provided control for many pests and could help decrease pesticide use.

“The major surprise was that, contrary to the usual claims, Bt maize is very likely to benefit poor farmers and small seed companies,” says de Groote. “Stem borers are a real concern for farmers, especially in low-potential coastal and dry areas.”

Farmers in Kenya lose 400,000 tons, or about 14%, of their maize to stem borers. That is roughly the amount the country imports each year. De Groote says Bt maize alone will not solve this problem, but could help reduce losses and increase food security.

The IRMA Project

In 1999, the Insect Resistant Maize for Africa (IRMA) project was launched in Kenya to develop borer resistant varieties using both conventional breeding and biotechnology. Kenya already had experience with genetically modified crops and had biosafety policies in place. IRMA, a collaborative project between CIMMYT and the Kenya Agricultural Research Institute, receives financial support from the Syngenta Foundation for Sustainable Agriculture.

Before initiating the project, all parties involved agreed that transformed plants would carry only the gene of interest, without marker genes; that transgenic crops would only be developed for countries with appropriate biosafety regulations; and that only genes in the public domain would be used. They also agreed that the project would work under the highest scientific standards. When the project ends, other countries in Africa will be able to evaluate results from Kenya’s experience and decide for themselves which path to follow.

“I hope that the results will be accepted not only by the scientific community but also by the general population, in Africa as well as in the developed world,” says de Groote. “I also hope they will put to rest some of the major concerns about Bt maize for Africa.”

To make informed choices possible, the researchers contend that scientists in Africa need hands-on experience with the new technology. They need to test and adapt it using the appropriate regulatory framework and precautions. Further, the researchers believe that the technologies need to be developed in a participatory approach, since African farmers and consumers have the right to choose technologies based on the best knowledge available. They should not be denied the chance to improve their livelihoods as a result of an academic debate in which they are not included.

Ethiopia study on biofortified maize reveals tasty results

Written by on . Posted in Features.

Quality protein maize can reduce or prevent stunted growth in young children, according to a recently published study.

nov02In eastern and southern Africa, maize is the least expensive and most prevalent cereal crop, but quantity cannot make up for quality. A maize-dominated diet helps keep bellies full, but does not provide a balanced diet. Specifically, maize lacks the essential amino acids lysine and tryptophan necessary for efficient protein synthesis. Quality protein maize (QPM)—a type of maize with increased levels of those two crucial amino acids—is the focus of a recent CIMMYT co-authored publication based on two studies conducted in separate locations in Ethiopia1.  The article delves into the role QPM can play in improving the nutritional status of young children in Ethiopia, where nearly 40% of children under five-years-old are underweight.

The first of the two studies ran from August 2002-03, in Wama Bonaya District, and showed that children who consumed QPM had a 15% increase in the rate of growth in weight over those who consumed conventional maize. The second study took place from October 2005-06 in the neighboring Sibu Sire District. Here, children fed a QPM diet had a growth rate in height 15% greater than that of children who ate conventional maize.

Both study sites were selected to represent high maize-producing and -consuming areas with high levels of child malnutrition. Sites were also selected based on environmental factors, such as rainfall and altitude, and for ease of operation for conducting the study. For almost all (97%) of the 341 participating households, farming was their sole occupation. Average farm size was 1.2 hectares. In both districts, maize was the dominant food for children—in Wama Bonaya  only 31% of families reported feeding their children foods other than maize, and in Sibu Sire 70% of the children regularly ate maize at least once a day. This highlights the vital role more nutritious maize could play in the future health and development of Ethiopian children.

Though there have been other studies on the effects and effectiveness of QPM (see Kernels with a kick: Quality protein maize improves child nutrition) this cumulative study varies slightly because it measures the effects of QPM when fully incorporated into the agricultural practices and home life of targeted households: study participants were given seed which they themselves grew and then prepared and consumed according to normal and locally-preferred practices, rather than being given pre-prepared QPM-based food products. This more closely mimics the impact QPM could have in a “real life” situation compared to some other previous study methods.

The study shows that although maize alone is not enough to sustain a nutrient-balanced diet, QPM can substantially improve the nutrition of children whose diets are, out of necessity, heavily based on one crop.

The paper was the result of collaboration among researchers Girma Akalu and Samson Taffesse of the Ethiopian Health and Nutrition Research Institute (EHNRI), Nilupa Gunaratna of the International Nutrition Foundation, and Hugo De Groote from CIMMYT-Kenya.

Resource conservation technologies for maize and wheat cropping systems

Written by on . Posted in News.

In partnership with national agricultural research systems, non-government organizations, agri-business, and international centers, CIMMYT undertakes research on conservation agriculture and resource conserving technologies for wheat and maize cropping systems.

Agronomy work at CIMMYT will focus strongly on conservation agriculture principles and approaches, which improve rural incomes and livelihoods through sustainable management of agro-ecosystem productivity and diversity, while minimizing unfavorable environmental impacts.

CIMMYT will examine the potential of plant pests and diseases in such systems and look at germplasm enhancements that reduce vulnerability. Beyond a focus on higher grain production and adapted germplasm, this research will seek more efficient and sustainable use of water and other inputs, lower production costs, better management of biotic stresses, and enhanced cropping system diversity and resilience.

When papa said no

CIMMYT E-News, vol 3 no. 7, July 2006

jul06A daring move by a young farmer in India has changed his life and his father’s.

Durgesh Kumar Singh shoulders a huge responsibility. When his father became too ill to work his small farm near Varanasi in the eastern Indo-Gangetic Plains, the 24- year-old student had little choice but to take on managing both the farm and his studies. His father was always there to give advice and share his farming knowledge, so when Durgesh decided to defy his father’s instructions, he was taking a big risk.

A team from the CIMMYT-convened Rice Wheat Consortium (RWC) for the Indo-Gangetic Plains had visited the villagers to enlist their cooperation in a demonstration of zero-till seeding technology. The team wanted village farmers to plant some of their wheat crop without plowing the soil first. Like people living on much of the vast plain below the foothills of the Himalayan Mountains, the farmers of Durgesh’s village plant wheat in the dry season, after harvesting the rainy-season rice crop. Preparing the land takes time and labor and for every day of delay after the optimal planting time, farmers lose about 1% of their potential harvest. A ten-day advance in wheat seeding results in 10% higher harvests. Plowing means waiting until a crew with a tractor and plow is available.

jul05

When the RWC team, which included Ramesh Chand and UP Singh from Banaras Hindu University, first visited the village, people laughed. “How can you expect the seed to germinate if you just throw it on the ground?” they joked. After two weeks of cajoling and pointing out that zero-tillage saves time, labor, and scarce water, the team convinced one farmer, Surindra Sharma Mayaran, to set aside a very small piece of his land for a trial. “If it works, OK, and if it doesn’t, OK,” he said. Even though the wheat germinated and grew, most villagers remained skeptical, especially Durgesh Singh’s father. He told Durgesh that he would die if his son tried to plant that way.

But seeing in that first trial a possibility for a brighter future, Durgesh decided to try zero-tillage for wheat on a small field that his father could not see from the house. He harvested at least as much as with the old methods, but gained something more precious. “We now have enough time to read,” he says. “My golden time is what I am saving.” This has not only let him continue his studies, but has reduced farm labor costs, making the family wheat crop more profitable. Now most of the villagers who were at first so skeptical are following his lead.

Even those who are nearly landless see benefits. Ram Dhari is what the village calls a “minimum landholder” with just a tenth of a hectare. He is extremely poor. He did not have the money to rent the zero-till seeding machinery, so the rest of the village let him use it for free and Banaras Hindu University provided seed. He had watched the others and wanted to follow. “I am looking forward to the profits,” he says.

This is one of countless stories of the success of a broad range of resource-conserving technologies on smallholder farms in India. RWC work, in India funded in large measure by the United States Agency for International Development (USAID), has won praise and awards. Recently the Minister of Agriculture for India, Sharad Pawar, said the use of such technologies, especially zero-tillage, was essential to the improvement of Indian agriculture.

Durgesh Singh, Ram Dhari and Surindra Mayaran see the impact in their village every day. At first Durgesh was a laughing stock. Now his zero-till fields have produced, and produced well. The father who said he would die if is son tried out such a foolish thing as planting without plowing now asks “Why didn’t you do the whole farm this way?”

1st ARIA-CIMMYT maize workshop in Kabul, Afghanistan

Written by on . Posted in News.

ARIA-CIMMYTCIMMYT, with support from the Australian Centre for International Agricultural Research (ACIAR), has been working on maize in Afghanistan for more than ten years, and has contributed to the release—led by the Agricultural Research Institute of Afghanistan (ARIA)—of four maize varieties. Historically, the national research and seed systems have not been as proactive for maize as they have for wheat. However, recognizing that maize can be an effective contributor to overall food production, the recent past has seen efforts to give maize its due importance as a food crop in Afghanistan. To this end, the first ARIA-CIMMYT maize workshop was held at the ARIA conference hall in Kabul on 30 April and 01 May 2012, with the aims of further systematizing maize research in the country and coordinating the efforts of stakeholders.

Maize is the fourth most important cereal crop in Afghanistan, accounting for about 6.8% of total cereal production. It has traditionally played a significant role in Afghan food, and during the pre-conflict period Afghanistan grew maize on about half a million hectares, with production reaching 0.7 million tons and productivity at 1.3–1.6 t/ha. During the last decade, productivity has ranged between 0.9 and 2.6 t/ha with signs of improvement, but the area planted to maize has fallen to about 180,000 hectares and total production has hovered around 0.3 million tones. The country has been importing maize to meet its needs, spending about four million USD during 2009.

The workshop was inaugurated by Sahib Dad Pakbin, senior advisor to ARIA. He welcomed the CIMMYT initiative and said he hoped the workshop would lead to increased coordination and more effective contributions by maize researchers in the country. Rajiv Sharma, CIMMYT’s country liaison officer for Afghanistan, highlighted the important supplementary role maize could play in enhancing wheat-based farm-level productivity. A total of 28 participants attended and gave presentations at the workshop, from ARIA, CIMMYT, the Afghan Ministry of Agriculture, Irrigation and Livestock (MAIL), FAO, the International Center for Agricultural Research in the Dry Areas (ICARDA), and private sector seed companies. The themes covered included the importance of maize in Afghanistan, maize agronomy, maize breeding, seed production, and the maize research network in Afghanistan.

All the participants were excited by the opportunity to collaborate with fellow researchers, in particular the ARIA maize researchers by the chance to connect with colleagues from other research stations. They expressed immense satisfaction at being able to share and link their proposed research plans for the ensuing maize season. ARIA director Qasem Obaidi thanked CIMMYT for its contributions in providing this opportunity and expressed the wish that it would be repeated in years to come to facilitate meaningful coordination, not only among researchers but also other stakeholders such as seed producers.

Pathways to intensification project formulated

Written by on . Posted in News.

During 27-28 April 2012, CIMMYT’s Socioeconomics Program organized a formulation meeting in Addis Ababa, Ethiopia for its Technology Adoption and Intensification Pathways project. More than 35 participants from five African countries attended the meeting. The group included economists, agronomists, and breeders, drawn from CIMMYT; the Australian Center for International Agricultural Research (ACIAR); the International Food Policy Research Institute (IFPRI); the International Livestock Research Institute (ILRI); national agricultural research institutions; the University of Queensland, Australia; the Norwegian University of Life Sciences (UMB); and universities from member countries of the Sustainable Intensification of Maize-Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) project. The objectives of the meeting were to discuss the project proposal with stakeholders, reflect on the in-house review comments by ACIAR, and develop the full proposal by developing a clear impact pathway. The four-year project is expected to develop actionable strategies and policy options for technology targeting and facilitating the adoption of integrated interventions.

The director of the Australian International Food Security Centre (AIFSC), Mellissa Wood, gave a keynote address on “New opportunities for enhancing food security in Africa”. She noted that food security remains an ongoing challenge in Africa, to which Australia is well placed to contribute thanks to its agricultural research expertise. The Australian Government has therefore renewed its focus on food security through rural development initiatives and the establishment of AIFSC. She pointed out that AIFSC’s mission is to accelerate demand-driven research, delivery and adoption of innovations to improve food security, by bridging the gap through agricultural research; understanding the requirements of smallholder production systems; understanding constraints to adoption of research outputs; and devising new modalities to overcome such constraints.

The meeting also benefited from key presentations by CIMMYT, partner institutions, and universities on key topics; break-out group discussions; and a brainstorming session. The new project has four main objectives: (1) panel data collection in sentinel villages and understanding of barriers to technology adoption; (2) risk analysis and adaptation options to manage climate risk and variability; (3) impact assessment and analysis of household intensification pathways; and (4) capacity building in gender-disaggregated agricultural policy analysis and communication of results.

The promise of spring maize for farmers in Haryana, India

Written by on . Posted in News.

HMRP-2012-Photo-Community-Seed-Promotors-Training-Rampur1For decades, rice and wheat have been the main crops grown in Haryana, India, but with increasing degradation of natural resources, the focus has turned to finding viable alternatives to ensure future food and livelihood security.

Over the last few years, high yielding maize hybrids have been tested during the short window following the potato harvest in Spring. The results are promising, showing that using a rice-potato-maize cropping system could produce more than 30 tons of food per hectare each year. This would increase not only productivity and profitability but would also address the emerging challenges of water scarcity and terminal heat effects, and offer solutions for different production environments.

To explore these findings in more detail, a multi-stakeholder consultation was organized by the Cereal Systems Initiative for South Asia (CSISA)-Haryana (CIMMYT-IRRI) in partnership with the CCS Haryana Agricultural University (HAU), Haryana State Department of Agriculture, Haryana Farmers Commission, the Directorate of Maize Research (DMR) of the Indian Council of Agricultural Research (ICAR), the Indian Maize Development Association (IMDA), and local maize farmers. The event, which took place on 19 April 2012 in Haryana, attracted around 350 farmers from five local districts, and 75 scientists and staff from public and private organizations.

The consultation included a farm visit, success stories, and presentations aiming to raise awareness about the potential of spring maize. Discussions explored domestic and international market potential; promotion of natural resource conservation methods; investments; technological advancements; new agricultural policy; and capacity building, not only for current farmers, but also for women and younger farmers.

Several speakers emphasized that joint effort would help to achieve more: CIMMYT cropping systems agronomist M.L. Jat suggested that building strong partnerships across the sector would be crucial for achieving sustainability, while R.S. Paroda of Haryana Kisan Ayog advised farmers to form self-help groups to share knowledge and experience.

Eminent scientist, former CIMMYT maize breeder, and World Food Prize laureate Surinder K. Vasal emphasized the need to strengthen research on maize hybrids in view of the changing climate. DMR director R. Sai Kumar explained how the available hybrids suited each different situation. Further support and advice was offered to farmers by J.S. Dhankar, director of extension education at CCS HAU and by IMDA president Sain Dass, who announced that he would ensure that the starch industry purchase all Haryana maize.

The government of Haryana’s additional director for agriculture, B.S. Duggal, also highlighted the incentive schemes available to promote agricultural diversification. Other participants included Indu Sharma, director of DWR, Karnal; Saroj Jaipal, head of RRS, HAU, Karnal; S.K. Gahlawat, deputy director of Agri, Karnal; Pradeep Meel deputy director of Agri, Yamunanagar; R.S. Sangwan, deputy director of Agri, Kurukshetra; S.P. Goyal, coordinator of Krishi Vigyan Kendras (KVK), Kurukshetra; Dalip Gosain, KVK coordinator, NDRI, Karnal; S.K. Sharma, head of CSSRI Karnal; Virender Kumar, research platform coordinator, CSISA Karnal; and B.R. Kamboj, hub manager, CSISA Haryana.

Version 3.2 of the QTL IciMapping software released

Written by on . Posted in News.

QTL IciMapping is freely-available public software capable of building high-density genetic maps and mapping quantitative trait loci (QTLs). Compared with previous versions, the latest version has five new features: dominant/recessive markers are considered in recombination frequency estimation, map construction and QTL mapping; a new functionality called IMP can be used to build an integrated map from multiple genetic linkage maps sharing common markers; a new tool called 2pointREC can be used to estimate the pair-wise recombination frequency in biparental populations; many more markers can be handled by this software— for example, it can perform map construction and QTL mapping of more than 5000 markers; and linkage map figures are improved.

The software is project-based; kernel modules for building linkage maps were written using C#, those for QTL mapping were written using Fortran 90/95, and the interface was written using C#. QTL IciMapping runs on 32 and 64-bit computers with Windows XP/Vista/7 and .NET Framework 2.0(x86)/3.0/3.5. Research and development of the software was supported mainly by the CGIAR Generation Challenge Program, National 863 Program, 973 Program, and the Natural Science Foundation of China. The latest version is freely available (here). For more information, contact Dr. Jiankang Wang (jkwang@cgiar.org or wangjk@caas.net.cn).

Strengthening the capacity of maize technicians in Zambia

Written by on . Posted in News.

course-in-ZambiaDuring the week of 15-20 April 2012, 36 maize technicians participated in a training session in Lusaka, Zambia. The participants were selected from seven seed companies in Zambia, national agricultural research organizations, and NGOs involved in agricultural research and extension in the eastern province of Zambia. The objective of the course was to update maize technical staff on implementing on-station and on-farm trials, seed production, and the use of secondary traits in selecting superior genotypes under low nitrogen, heat and drought trials, and it combined both lectures and field work.

Well-managed experiments provide the foundation of all research towards germplasm improvement. Technicians are responsible for many day-today field activities and much agronomic management, making their training crucial in strengthening the capacity of national programs. The course was organized by three CIMMYT projects—Drought Tolerant Maize for Africa (DTMA), Sustainable Intensification of Maize-Legume Systems for the Eastern Province of Zambia (SIMLEZA) and Improved Maize for African Soils (IMAS.—in collaboration with the Zambian Agricultural Research Institute (ZARI). It was designed to give technicians greater insight into key processes within germplasm development, variety testing and release, and seed production. Emphasis was given to the importance of trial uniformity, good agronomic management practices, and standardizing measurements.

Each project contributed specialized content to the course: under DTMA the focus was on how to select genotypes under managed drought and heat stress, develop a seed production strategy using seed road maps and maintain trial uniformity. The SIMLEZA project emphasized on-farm testing using the Mother-Baby Trial approach while under IMAS the emphasis was on developing low nitrogen sites and important traits to select for production under low nitrogen. CIMMYT thanks the course organizers and resource persons, Kambambe Mwansa and Franscico Miti of the Zambian Agricultural Research Institute, and CIMMYT’s Peter Setimela, Jill Cairns, Biswanath Das and Sebastian Mawere.

Ensuring a market for maize seed produced using community based seed production (CBSP) in the value chain system, and enhancing management and marketing competencies of local partners are among the strategic activities in Phase IV of the Hill Maize Research Project (HMRP), supported by SDC and USAID. The HMRP, in collaboration with the National Maize Research Program (NMRP), completed a 20-day training course on maize seed production technologies (15 days) and seed business plan development and marketing (5 days). The course took place at NMRPRampur, Chitwan, from 27 March to 16 April 2012. A total of 31 participants (11 women) attended the course; they were selected from CBSP groups collaborating with HMRP and are expected to work as community seed promoters in their respective groups afterwards.

The first course component on maize seed production technologies covered diverse topics, such as agronomic practices in maize seed production, farmers’ practices in maize varietal development, source seed production technologies, crop management technology (including insect pest management), improved seed production through CBSP, quality control, and truthful labelling. The second component covered HMRP seed marketing strategies, agricultural marketing, seed production costs, maize seed value-chain analysis, seed business plan development, bookkeeping at the CBSP group level, potential sourcing of local state funds by CBSP groups, the importance of gender equity and social inclusion in the CBSP approach, an introduction to cooperatives and private companies, and the basic legal requirements to establish them.

Each trainee developed a comprehensive action plan and presented it on the last day of the course. Participants were evaluated before and after each course component and the first-ranked candidate was recognized. Speaking at the closing session, Dr. K.B. Koirala, NMRP National Coordinator, expressed his appreciation to the HMRP and emphasized the importance of this type of training for empowering local communities. Dr. G. Ortiz-Ferrara, HMRP Team Leader, thanked the course participants, training coordinator, and resource persons for their help and cooperation in making the course a success. Finally, Dr. Koirala and Dr. Ortiz-Ferrara jointly distributed certificates and training kits to all participants.

Workshop on enabling technologies and environments for climate resilient future farming systems in Jharkhand, India

Written by on . Posted in News.

A two-day workshop on potential technologies and policy environments for smallholder rainfed maize farming systems of Jharkhand state, India was organized jointly by Birsa Agriculture University (BAU), CIMMYT, and the International Plant Nutrition Institute (IPNI) during 16-17 April, 2012 at Ranchi, Jharkhand, India. The outcomes of the workshop will form part of CIMMYT’s IFAD-funded project on “Sustainable Intensification of Smallholder Maize-Livestock Farming Systems in Hill Areas of South Asia” and the MAIZE CGIAR Research Program (CRP).

There were 69 participants in total, including scientists, extension agents (KVKs), and students from BAU; key officials from the state department of agriculture National Food Security Mission (NFSM); and scientists from IPNI, the International Livestock Research Institute (ILRI), and CIMMYT. The workshop was inaugurated by BAU vice chancellor M.P. Pandey, while sessions and break-out group discussions were facilitated by Kaushik Majumdar, director of IPNI’s South Asia Program; JS Choudhary, state NFSM director; AK Sarkar, dean of the College of Agriculture at BAU; ILRI scientist Nils Teufel; CIMMYT scientists M. L. Jat and Surabhi Mittal; and IPNI deputy director T. Satyanarayana.

The workshop was made up of presentations on key topics, break-out group discussions, and a brainstorming session. The overall key themes were: (1) current status, constraints, and opportunities in different regions of Jharkhand , (2) conservation agriculture in maize and wheat systems, (3) approaches for crop-livestock integration, (4) integrated farming systems for food and nutritional security, (5) optimizing nutrient management for improved yield and profitability, and (6) approaches for inclusive growth for Jharkhand.

The five break-out groups discussed conservation agriculture (CA); site-specific nutrient management (SSNM); integrated farming systems and crop livestock interactions; enabling policies; and knowledge gaps, partnerships, networks and scaling-out strategies. The discussion outcomes were particularly focused on technology targeting and enabling environments and policies.

Agriculture in Jharkhand is at very low cropping intensity (~114%), despite good rainfall in most districts. The most critical issues include: rolling topography with very small holdings, leading to severe erosion due to lack of appropriate rainwater harvesting; soil acidity; lack of high-yielding stress-tolerant cultivars; very limited mechanization; and poor farmer access to inputoutput markets, coupled with resource poverty.

Building on the experience of CIMMYT’s hill maize project in the state, the participants agreed that optimizing cropping systems deploying CA practices could alleviate many of these problems, and sustainably increase crop production and productivity. Integrating CA with SSNM has shown promising results in improving nutrient use efficiency, currently another bottleneck in productivity gains due to inappropriate nutrient use. Crop-livestock integration is also key, as animals dominate farming in Jharkhand.

To implement these technologies and practices on a large scale, policy support is crucial. The outcomes of the workshop are being documented to serve as a policy paper for prioritization and implementation of technologies by the state, with the goal of arresting land degradation, improving crop productivity, and improving resource use efficiency and farm profitability.

IITA recognizes DTMA project leader Wilfred Mwangi

Written by on . Posted in News.

From 16 to 19 April 2012, the Drought Tolerant Maize for Africa (DTMA) project held its regional planning meeting for West Africa in Kumasi, Ghana. During the meeting, IITA Director General Nteranya Sanginga presented Wilfred Mwangi, DTMA Project Leader, with a plaque in “recognition of his leadership in building strong partnerships among diverse institutions for successful implementation of the DTMA project in sub-Saharan Africa”.CIMMYT work revolves around leveraging partnerships. At a maize and wheat meeting in January, Deputy Director General for Research and Partnerships Marianne Bänziger described Mwangi as “a person who builds bridges.”

Since the inception of DTMA, Mwangi, who is also Associate Director of the Global Maize Program and Regional Liaison Officer, has been involved in building partnerships with donors, research institutions, and seed companies in 13 countries across the region. “To have a sister institution recognize our partnership is really great,” said Mwangi noting that getting everyone involved in the project to read from the same script has not been an easy task.

MELISA: Mechanization for SIMLESA

Written by on . Posted in News.

Farm mechanization has progressed little if at all in sub-Saharan Africa, due to a lack of demand, promotion of unsuitable or unreliable machines, little support infrastructure, promotion of inappropriate machinery, an overriding development focus on seeds and fertilizer, and negative perceptions about the social and equity effects of mechanization.

During 10-13 April 2012, more than 50 participants from 12 countries in eastern and southern Africa took part in a workshop organized by the CIMMYT global conservation agriculture program to re-explore the issue and help develop a proposal for the project “Mechanization, entrepreneurship, and conservation agriculture to leverage sustainable intensification in eastern and southern Africa” (MELISA), which will build upon the ACIAR-funded project SIMLESA. The group included agronomists, socioeconomists, agricultural engineers, and private sector representatives.

Re-opening the debate about mechanization was deemed timely because farming in the region relies on increasingly fewer draft animals, tractor hiring schemes have collapsed, field labor is in ever-shorter supply, and the extreme drudgery of many farm operations often falls to women and generally makes agriculture unattractive to the young.

The project is expected to build on experiences with small-scale, intensified farming systems in South Asia—for example, 80% of all operations in Bangladesh are mechanized and mostly done by service providers—and on SIMLESA networks and activities to test and promote conservation agriculture. Both small-scale mechanization and conservation agriculture promise to improve smallholders’ “power” budget: mechanization increases the supply, whereas conservation agriculture reduces the demand by about half; thus smaller, more affordable sources of power, such as two-wheel tractors, can be used. Similarly, shifting from draft animals to tractors would free up substantial biomass (a pair of oxen consumes about nine tons of forage per year) that can be left as residues on the soil. As specific objectives, MELISA will:

  1. evaluate and demonstrate small-scale motorized conservation agriculture technologies in Ethiopia, Kenya, Mozambique, Malawi, Tanzania, and Zimbabwe, using expertise, knowledge, skills, and implements from Africa, South Asia, and Australia;
  2. test site-specific market systems to support mechanization in those countries;
  3. identify improvements in national policies and markets for wide adoption; and
  4. create awareness and share knowledge about mechanization.

The project will be submitted to ACIAR Australia and, if approved, could start in late 2012.
