Slow-release nitrogen fertilizers measure up

Maize, rice and wheat are the major staple crops in Nepal, but they are produced using a lot of fertilizer, which may become an environmental hazard if not completely used up in production. Unfortunately, most farmers apply fertilizers in an unbalanced way.

Urea is a common fertilizer used as a nitrogen source by Nepali farmers. If the time of application is not synchronized with crop uptake, the chances of losses through volatilization releasing ammonia and leaching are high, thereby creating environmental hazards in the atmosphere and downstream.

Through the Nepal Seed and Fertilizer (NSAF) project, the International Maize and Wheat Improvement Center (CIMMYT) is testing the application of environmentally friendly slow-release nitrogen fertilizer in maize production.

In particular, CIMMYT researchers examined the nutrient-use efficiency of briquetted urea and polymer-coated urea, also known as PCU.

Using regular urea, the efficiency of nitrogen use in maize is limited to 17 kg of grain per kg of nitrogen. Using briquetted urea and polymer-coated urea, efficiency increased to 24 and 28 kg of grain per kg of nitrogen respectively. A higher efficiency also suggests a reduction in losses to the environment.

Overall, results show that briquetted urea and polymer-coated urea can allow reduced nitrogen inputs by as much as 30-40% while maintaining the same yield levels achieved using current government fertilizer recommendations.

Similar to the maize trials, the application of slow-release nitrogen at a lower amount than the recommended rate in wheat showed similar agronomic results to the application of traditional urea at higher rates. Reduced losses allowed 40-50% less nitrogen fertilizer application but maintained the same yield levels as the current recommendation.

Although the cost of polymer-coated urea is comparatively expensive in the market unless subsidized, farmers applying briquetted urea save money and labor and can obtain 54% more profits.

“Briquetted urea is easy to use compared with traditional urea application, since its one-time application method saves labor. Moreover the yield performance is better,” said Devi Sara Thapa, a farmer from Surkhet district.

Climate change is affecting the yield of crops due to increased exposure to higher temperature, water stress and delayed or reduced monsoons, all impacting farmers’ incomes. The NSAF project promotes early maturing crop varieties that are resilient to such climatic stresses and can yield a positive harvest. The project works with seed companies and Nepal’s Ministry of Agriculture, Livestock and Development to deploy stress resilient maize and rice varieties packaged with cost efficient and effective soil fertility management practices in the project areas.

Researchers are testing and promoting early and extra early maturing open-pollinated varieties that have tolerance to drought or water stress conditions. These varieties are found to yield up to 7.5 tons per hectare and are ready for harvest in less than 100 days. This allows farmers, particularly in the hills and mid hills, to have another crop in the growing season. Such varieties will enhance farmers’ productivity and ensure food security at times of stressful environmental conditions.

CIMMYT is sharing the benefits of adopting these technologies to farmers, cooperatives and ago-dealers, through field demonstrations and farmer field days.

Project staff and partners use seeds and fertilizers that are approved by the Government of Nepal and the United States Agency for International Development’s environmental regulations on pesticide use or support. The team is promoting seed varieties appropriate for specific agroecological conditions and applying best practices on the use and application of fertilizers and integrated soil fertility management.

The Nepal Seed and Fertilizer (NSAF) project, implemented by the  International Maize and Wheat Improvement Center (CIMMYT), aims to increase the availability of agriculture technologies to improve productivity in select value chains, including maize, rice, lentils, and high-value vegetables. Through the NSAF project, CIMMYT and its partners work to improve the capacity of the public and private sectors in their respective roles: to strengthen and develop commercial seed and fertilizer value chains and to develop markets systems to disseminate agricultural technologies throughout Nepal.

Looking forward, looking back

Over 50 stakeholders from the Sustainable and Resilient Farming Systems Intensification in the Eastern Gangetic Plains (SRFSI) project engaged in three days of reflection and planning in Kathmandu, Nepal, in early May 2019. Partners from four countries focused on identifying key learnings across a range of topics including value chains, business models, agricultural extension, capacity building, innovation platforms and policy convergence. After almost five years of project activities, there was naturally plenty of vibrant discussion.

The cross-cutting themes of gender and climate change were considered within each topic, to capture project outputs beyond participation and farm level impact. Discussions around gender confirmed the benefits of targeted women’s participation and ensuring that women’s availability was accommodated. Working within the SRFSI project, researchers have identified new business opportunities for women, with benefits for individuals and community groups. In terms of business models, it was highlighted that promoting gender-inclusive strategies for all partners, including the private sector, is necessary. Ensuring a wide range of partnership institutions, such as NGOs with women-centric programs, is also beneficial for reaching more women.

Conservation agriculture-based sustainable intensification techniques have been confirmed as contributing to climate-resilient farming systems, both in terms of mitigation and adaptation. Importantly, the project has demonstrated that these systems can be profitable, climate smart business models in the Eastern Gangetic Plains. They were also seen as fitting well with government plans and policies to address climate change, which was demonstrated by convergence with country and NGO programs that are focused on climate change adaptation.

In keeping with the recently approved no-cost extension of the SRFSI project until June 2020, the final sessions identified remaining research questions in each location and scaling component, and project partners nominated small research activities to fill these gaps. The final year of SRFSI is an excellent opportunity to capture valuable lessons and synthesise project outputs for maximum impact.

The Sustainable and Resilient Farming Systems Intensification Project is a collaboration between the International Maize and Wheat Improvement Center (CIMMYT) and the project funder, the Australian Centre for International Agricultural Research (ACIAR).

New role in Nepal is “a dream come true”

Cynthia Carmona will always remember the directive her supervisor gave to a researcher panicked by mounting paperwork: You go and work on the science. We’ll take care of the admin part.

“They already have their hands full with research and building partnership strategies. They shouldn’t have to be concerned about whether or not an invoice has been sent,” she says.

Growing up in the Mexican state of Sonora, Carmona was aware of the International Maize and Wheat Improvement Center’s (CIMMYT) Obregon experimental station from a young age. “It was an organization that I knew existed, but all I knew was that they worked on wheat.”

After studying international relations at Tecnológico de Monterrey in Mexico City, Carmona spent a couple of years working in government and the private sector but she remained on the look-out for global-facing opportunities. Drawn to the opportunity to work with donors, Carmona joined CIMMYT’s Project Management Unit (PMU) six years ago.

“When I first arrived it was more of a grant management unit and we were divided by grant cycle. One person would work on proposals, another on contracts and so on, so you didn’t really get to see the whole process from start to finish.”

The unit has evolved since then, and growing responsibility means that the team is now divided by specialty, from donor relations and resource mobilization to grant management and monitoring and evaluation. “The structure we have now definitely gives you a broader understanding of each project.”

Carmona stresses that even though PMU staff don’t work in the field or in laboratories, they do make significant contributions to project implementation by encouraging smoother processes, alleviating administrative problems and ‘speaking a common language’ between researchers and management. When she took on the role of grant management coordinator, she impressed upon her team the extent to which their action or inaction could affect the projects they support. “Making things happen was my favorite part of the role, and I saw my job as that of an ‘issue solver’.”

Carmona is currently based in Kathmandu, Nepal, where she is serving as interim project manager on CIMMYT’s Cereal Systems Initiative for South Asia (CSISA) project.

“I’m very excited about this new opportunity. CSISA has always been a flagship project for CIMMYT, so when they invited me to help them it was like a dream come true.”

She first visited Nepal in December 2018, where she spent time shadowing the outgoing manager who provided her with an introduction to the country, the region and the project itself.

“It was like a two-week bootcamp. But even though it was intense, I didn’t feel overwhelmed.”

Working in PMU, Carmona explains, provides a solid background for project management and an understanding of how CIMMYT projects work, from start to finish, as well as how to communicate with funders and build shared knowledge by bringing people together, from scientists and researchers to program and service unit staff.

Besides learning about how a project is run on-the-ground, Carmona is most looking forward to gaining field experience while in Nepal. “Talking to farmers and project teams, listening to their experiences and witnessing CIMMYT’s work on-the-ground really gives you a sense of belonging and a connection to our mission.”

Sustainable and Resilient Farming Systems Intensification in the Eastern Gangetic Plains (SRFSI)

The Eastern Gangetic Plains region of Bangladesh, India, and Nepal is home to the greatest concentration of rural poor in the world. This region is projected to be one of the areas most affected by climate change. Local farmers are already experiencing the impact of climate change: erratic monsoon rains, floods and other extreme weather events have affected agricultural production for the past decade. The region’s smallholder farming systems have low productivity, and yields are too variable to provide a solid foundation for food security. Inadequate access to irrigation, credit, inputs and extension systems limit capacity to adapt to climate change or invest in innovation. Furthermore, large-scale migration away from agricultural areas has led to labor shortages and increasing numbers of women in agriculture.

The Sustainable and Resilient Farming Systems Intensification (SRFSI) project aims to reduce poverty in the Eastern Gangetic Plains by making smallholder agriculture more productive, profitable and sustainable while safeguarding the environment and involving women. CIMMYT, project partners and farmers are exploring Conservation Agriculture-based Sustainable Intensification (CASI) and efficient water management as foundations for increasing crop productivity and resilience. Technological changes are being complemented by research into institutional innovations that strengthen adaptive capacity and link farmers to markets and support services, enabling both women and men farmers to adapt and thrive in the face of climate and economic change.

In its current phase, the project team is identifying and closing capacity gaps so that stakeholders can scale CASI practices beyond the project lifespan. Priorities include crop diversification and rotation, reduced tillage using machinery, efficient water management practices, and integrated weed management practices. Women farmers are specifically targeted in the scaling project: it is intended that a third of participants will be women and that at least 25% of the households involved will be led by women.

The 9.7 million Australian dollar (US$7.2 million) SRFSI project is a collaboration between CIMMYT and the project funder, the Australian Centre for International Agricultural Research. More than 20 partner organizations include the Departments of Agriculture in the focus countries, the Bangladesh Agricultural Research Institute, the Indian Council for Agricultural Research, the Nepal Agricultural Research Council, Uttar Banga Krishi Vishwavidyalaya, Bihar Agricultural University, EcoDev Solutions, iDE, Agrevolution, Rangpur-Dinajpur Rural Services, JEEViKA, Sakhi Bihar, DreamWork Solutions, CSIRO and the Universities of Queensland and Western Australia.

OBJECTIVES

  • Understand farmer circumstances with respect to cropping systems, natural and economic resources base, livelihood strategies, and capacity to bear risk and undertake technological innovation
  • Develop with farmers more productive and sustainable technologies that are resilient to climate risks and profitable for smallholders
  • Catalyze, support and evaluate institutional and policy changes that establish an enabling environment for the adoption of high-impact technologies
  • Facilitate widespread adoption of sustainable, resilient and more profitable farming systems

Hill Maize Research Project (HMRP)

The Hill Maize Research Project (HMRP), funded by the Swiss Agency for Development and Cooperation was initiated in 1999 with the objective of increasing the food security of farm families in the hills of Nepal by raising the productivity and sustainability of maize-based cropping systems. The HMRP went through three phases between 1999 and 2010, the fourth and final phase began in August 2010 and concluded in 2015. There are two key outcomes for the project.

First, farm households in the hills of Nepal, especially those belonging to women, poor and disadvantaged groups, have improved food security and income.

Second, the National Seed Board, the Nepal Agricultural Research Council and the Department of Agriculture enforce quality control in both public and private institutions.

OBJECTIVES

  • Farm households in the hills of Nepal, especially of poor and disadvantaged groups, have improved food security and income.
  • Available varieties and technologies are used
  • Poor and disadvantaged households have increased access to quality maize seed and proven technologies
  • Groups/cooperatives supply quality seeds at competitive market prices
  • Poor and disadvantaged maize producing households will have access to multiple agricultural interventions for enhanced productivity
  • The National Seed Board (NSB), NARC, and the DoA allow decentralization of the source seed production system
  • Public and private institutions obtain seed inspection mandate and license
  • CBSP/cooperatives manage supply of quality seed
  • The NSB and NARC consider HMRP’s experience in variety development, certification and release system

Nepal Seed and Fertilizer Project (NSAF)

The Nepal Seed and Fertilizer (NSAF) project facilitates sustainable increases in Nepal’s national crop productivity, income and household-level food and nutrition security, across 20 districts, including five earthquake-affected districts.

Nepal’s agriculture is mostly small-scale and subsistence-oriented, characterized by a mix of crop and livestock farming. The agriculture sector represents about one-third of the country’s gross domestic product and employs 75 percent of the labor force.

Over half of Nepal’s farms operate on less than half a hectare, with the majority unable to produce enough to meet their household food requirements for the whole year. Combined with an increasing urban population, it will not be possible for the country to meet future food demand without increased agricultural productivity and competitiveness of domestic production.

Major cereal crops and vegetables currently have low yields, but there are significant prospects for increases through improved seed and soil fertility management practices. A large part of this yield gap results from a lack of knowledge, inadequate access to affordable improved technologies, extension services and markets due to weak public and private sector capacity to provide support services needed by small scale farmers.

NSAF promotes the use of improved seeds and integrated soil fertility management technologies along with effective and efficient extension, including the use of digital and information and communications technologies. The project will specifically increase availability of technologies to improve productivity in cauliflower, lentils, maize, onions, rice and tomatoes. It will also build competitive seed and fertilizer systems that significantly expand seed production, marketing and distribution by enhancing the capacity of public and private sectors in seed and fertilizer value chains.

Agriculture development needs to be locally owned and led through inclusive business models involving women and disadvantaged groups and farmers institutions. There is a need to further the development of Nepal’s cereals, legumes and vegetable sector by:

  • Strengthening public-private coordination mechanisms
  • Developing market systems that are agile, resilient, and adaptive
  • Propelling agricultural growth through evidence-based policy change and harmonization.

Food security in Ukraine

Supplemental funds released in 2022 will be used to respond to the impact of the Ukraine war at the household level. CIMMYT and its partners will develop food security and resilient agriculture market systems, to advance the delivery of improved agriculture input management knowledge and technologies, application of best crop management practices, and development of local capacity to apply improved technologies.

The objective is to build resilience of smallholder farmers in four areas:

  • Protecting and sustaining crop production for strengthening local food production and consumption systems.
  • Supporting efficient agriculture supply chain.
  • Strengthening local cooperatives and micro, small- and medium-sized agribusiness enterprises.
  • Addressing the impact of global fertilizer shortages by exploring innovative products, novel application techniques and local market development.

Heat Stress Tolerant Maize for Asia (HTMA)

The Heat Stress Tolerant Maize (HTMA) for Asia project is a public-private alliance that targets resource-poor people and smallholder farmers in South Asia who face weather extremes and climate-change effects. HTMA aims to create stable income and food security for resource-poor maize farmers in South Asia through development and deployment of heat-resilient maize hybrids.

South Asian farmlands have been increasingly experiencing climate change-related weather extremes. If current trends persist until 2050, major crop yields and the food production capacity of South Asia will decrease significantly – by 17 percent for maize – due to climate change-induced heat and water stress.

In response, CIMMYT and partners are developing heat stress-resilient maize for Asia. The project leverages the germplasm base and technical expertise of CIMMYT in breeding for abiotic stress tolerance, coupled with the research capacity and expertise of partners.

OBJECTIVES

  • Future climate data obtained from the recent CIMP5 database, and future and current heat stress hot-spots in South Asia are mapped
  • Genome-wide association studies revealed multiple haplotypes significantly associated heat tolerance, including nine significant haplotype blocks (~200 kb) for grain yield explaining 4 to 12% phenotypic variation individually with the effect size varied up to 440 kg/ha.
  • A total of 17 first generation heat tolerant hybrids formally licenced to project partners for deployment and scale-out in their targeted geographies/market in stress-prone ecologies of South Asia
  • New base germplasm, including early generation lines and pedigree populations, with enhanced levels of heat tolerance shared with partners to use in their own breeding programs.
  • Over 130 maize researchers and technical staff from India, Nepal, Pakistan and Bangladesh, including 32 women and 99 men, were trained on various aspects of developing stress-resilient maize through four training course workshops organized under the project.
  • Strong phenotyping network for heat stress in South Asia, with well-equipped locations and trained representatives.

Cereal Systems Initiative for South Asia (CSISA)

Intensive cereal cropping systems that include rice, wheat and/or maize are widespread throughout South Asia. These systems constitute the main economic activity in many rural areas and provide staple food for millions of people. The decrease in the rate of growth of cereal production, for both grain and residue, in South Asia is therefore of great concern. Simultaneously, issues of resource degradation, declining labor availability and climate variability pose steep challenges for achieving the goals of improving food security and rural livelihoods.

The Cereal Systems Initiative for South Asia (CSISA) was established in 2009 to promote durable change at scale in South Asia’s cereal-based cropping systems.

The project’s aim is to enhance the productivity of cereal-based cropping systems, increase farm incomes and reduce the environmental footprint of production through sustainable intensification technologies and management practices.

Operating in rural “innovation hubs” in Bangladesh, India and Nepal, CSISA complements regional and national efforts and involves public, civil society and private sector partners in the development and dissemination of improved cropping systems, resource-conserving management technologies, policies and markets. CSISA supports women farmers by ensuring their access and exposure to modern and improved technological innovations, knowledge and entrepreneurial skills that can help them become informed and recognized decision makers in agriculture.

The project is led by CIMMYT with partners the International Rice Research Institute and the International Food Policy Research Institute and funded by the U.S. Agency for International Development and the Bill & Melinda Gates Foundation.

OBJECTIVES

  • Promote resource-conserving practices, technologies and services that increase yield with less water, labor and input costs
  • Impart new knowledge on cropping management practices, from applied research
  • Improve access to market information and enterprise development.
  • Strengthen policy analysis to remove constraints to the adoption of new technologies
  • Build strategic partnerships and capacity to help sustain and enhance the scale of benefits of improved cereal growth

Core research to impact themes within CSISA include:

  • Coping with climate extremes in rice-wheat cropping systems
  • Accelerating the emergence of mechanized solutions for sustainable intensification
  • Strengthening the foundations of agro-advisory and precision management through knowledge organization and data integration at scale
  • Increasing the capacity of partners to conduct participatory science and field reconnaissance to target and prioritize development interventions

Finding the story behind weeds

The main focus of the Sustainable and Resilient Farming Systems Intensification (SRFSI) project is on conservation agriculture technologies. Since farmers may face an increase in weeds after adopting zero-till planters, however, more research is needed about how farmers are dealing with weed.

One of the research objectives of the project is to understand farmers’ knowledge, perception, and practices of conservation agriculture. To this end, researchers are using the Photovoice methodology in Cooch Behar (West Bengal, India), Rongpur (Bangladesh) and Sunsari (Nepal) to collect relevant data on weed management practices.

Photovoice is a visual qualitative research method that allows people to express their perspectives through photographs. Photography can be used for evaluation purposes, through storytelling exercises.

On December 6-7, 2019, field technicians in Bangladesh, India and Nepal participated in a training about this methodology. They learned the rationale of Photovoice, its technical and logistic aspects, as well as the ethical considerations and the need to collect consent forms.

Participants also learned how to take pictures of inter-row cultivation and weeds on the farm, and how to confirm the geolocation of the farm.

Worth a thousand words

Using the Photovoice method, 30 households will be explored, including their labor allocation and decision-making dynamics around the implementation of conservation agriculture practices.

The effectiveness of this approach will emerge as smallholder farmers present their perspectives through photographs accompanied by their narratives.

Activities will be monitored on weekly basis.

The SRFSI project, funded by the Australian Centre for International Agricultural Research (ACIAR) and led by the International Maize and Wheat Improvement Center, is set to improve the productivity, profitability and sustainability of smallholder agriculture in the Eastern Gangetic Plains of Bangladesh, India and Nepal, by promoting sustainable intensification based on conservation agriculture technologies.

Breaking Ground: Tek Sapkota finds ways to reduce emissions from agriculture without compromising food security

Breaking Ground Postcard TEK SAPKOTA

As the world population increases, so does the need for food. “We need to produce more to feed increasing populations and meet dietary demands,” says Tek Sapkota, agricultural systems and climate change scientist at the International Maize and Wheat Improvement Center (CIMMYT). In the case of agriculture, the area of land under cultivation is limited, so increased food production has to come through intensification, Sapkota explains. “Intensification means that you may be emitting more greenhouse gases if you’re applying more inputs, so we need to find a way to sustainable intensification: increase the resilience of production systems, but at the same time decrease greenhouse gas emissions, at least emission intensity.”

Sapkota is involved in a number of global climate change science and policy forums. He represents CIMMYT in India’s GHG platform, a multi-institution platform that regularly prepares greenhouse gas emission estimates at the national and state levels and undertakes relevant policy analyses. Nominated by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) and his country, Nepal, he is one of the lead authors of the “special report on climate change and land” of  the Intergovernmental Panel on Climate Change (IPCC).

He coordinates climate change mitigation work at CIMMYT. “I am mainly involved in quantification of greenhouse gas emissions and the environmental footprint from agricultural production systems, exploring mitigation options and quantifying their potential at different scales in different regions,” Sapkota says. In addition, he explores low-carbon development activities and the synergies between food production, adaptation and mitigation work within the different components of CIMMYT’s projects.

Agriculture is both a victim of as well as a contributor to climate change, Sapkota explains. “Climate change affects all aspects of food production, because of changes in temperature, changes in water availability, CO2 concentrations, etc.,” he says. “The other side of the coin is that agriculture in general is responsible for about 25 to 32 percent of total greenhouse gas emissions.”

Tek Sapkota (center) stands for a group photo with other scientists working on the IPCC’s special report on climate change and land, at the second lead author meeting in Christchurch, New Zealand, in March 2018.

Measuring emissions and examining mitigation options

A big part of Sapkota’s work is to find ways to mitigate the effects of climate change and the emissions from the agricultural sector. There are three types of mitigation measures, he explains. First, on the supply side, agriculture can “increase efficiency of the inputs used in any production practice.” Second, there’s mitigation from the demand side, “by changing the diet, eating less meat, for example.” Third, by reducing food loss and waste: “About 20 percent of the total food produced for human consumption is being lost, either before harvest or during harvest, transport, processing or during consumption.”

Sapkota and his team analyze different mitigation options, their potential and their associated costs. To that purpose, they have developed methodologies to quantify and estimate greenhouse gas emissions from agricultural products and systems, using field measurement techniques, models and extrapolation.

“You can quantify the emission savings a country can have by following a particular practice” and “help countries to identify the mitigation practices in agriculture that can contribute to their commitments under the Paris climate agreement.”

Their analysis looks at the biophysical mitigation potential of different practices, their national-level mitigation potential, their economic feasibility and scalability, and the country’s governance index and readiness for finance — while considering national food security, economic development and environmental sustainability goals.

Recently, Sapkota and his colleagues completed a study quantifying emissions from the agricultural sector in India and identifying the best mitigation options.

This type of research has a global impact. Since agriculture is a contributor to climate change “better management of agricultural systems can contribute to reducing climate change in the future,” Sapkota says. Being an important sector of the economy, “agriculture should contribute its share.”

Impact on farmers

Sapkota’s research is also helping farmers today. Inefficient use of products and inputs is not only responsible for higher greenhouse gas emissions, but it also costs farmers more. “For example, if farmers in the Indo-Gangetic Plain of India are applying 250 to 300 kg of nitrogen per hectare to produce wheat or rice, by following precision nutrient management technologies they can get similar yield by applying less nitrogen, let’s say 150 kg.” As farmers cut production costs without compromising yield, “their net revenue from their products will be increased.”

Farmers may also get immediate benefits from government policies based on the best mitigation options. “Governments can bring appropriate policy to incentivize farmers who are following those kinds of low-emission technologies, for example.”

Farmers could also get rewarded through payments for ecosystem services or for their contribution to carbon credits.

Sapkota is happy that his work is beneficial to farmers. He was born in a small village in the district of Kaski, in the mid-hills of Nepal, and agriculture was his family’s main livelihood. “I really enjoy working with farmers,” he says. “The most fascinating part of my work is going to the field: talking to farmers, listening to them, learning what kind of farming solutions they’re looking for, and so on. This helps refine our research questions to make them more strategic, because the way farmers look at a problem is sometimes entirely different from the way we look at it.”

When he was in Himalaya Secondary School, he studied agriculture as a vocational subject. “I was interested because we were doing farming at home.” This vocation got cemented in university, in the 1990s. When he heard about the agricultural industry and the future opportunities, he decided to pursue a career in science and focus on agriculture. He got his bachelor’s and master’s degree of science in agriculture from the Institute of Agriculture and Animal Science (IAAS), Tribhuvan University, in Nepal.

A global path

He first heard about CIMMYT when he was doing his master’s. “CIMMYT was doing research in maize- and wheat-based plots and systems in Nepal. A few of my friends were also doing their master theses with the financial support of CIMMYT.” After his master’s, he joined an organization called Local Initiatives for Biodiversity, Research and Development (LI-BIRD) which was collaborating with CIMMYT on a maize research program.

Sapkota got a PhD in Agriculture, Environment and Landscapes from the Sant’Anna School of Advanced Studies in Italy, including research in Aarhus University, Denmark.

After defending his thesis, in 2012, he was working on greenhouse gas measurement in the University of Manitoba, Canada, when he saw an opening at CIMMYT. He joined the organization as a post-doctoral fellow and has been a scientist since 2017. Sapkota considers himself a team player and enjoys working with people from different cultures.

His global experience has enriched his personal perspective and his research work. Through time, he has been able to see the evolution of agriculture and the “dramatic changes” in the way agriculture is practiced in least developed countries like Nepal. “When I was a kid agriculture was more manual 
 but now, a lot of technologies have been developed and farmers can use them to increase the efficiency of farming”.

KATHMANDU, Nepal (CIMMYT) — Maintenance and enhancement of soil fertility are vital for food security and environmental sustainability. However, a baseline survey conducted through the Nepal Seed and Fertilizer (NSAF) project shows that 95 percent of farmers have poor agronomic literacy. Most of them have little or no knowledge of proper seed and soil management practices, and do not apply fertilizer appropriately. Many farmers are also unaware of micronutrients and their specific role in crop production, so they spray micronutrient solutions as advised by agrovets. While quality seed and mineral fertilizer use are necessary to improve crop yields, use alone is not sufficient to maximize efficiency — how to use these tools is equally, if not more, important.

All these challenges indicate a need to educate farmers and help them adopt good agronomic practices that will maximize crop production and productivity.

As part of the NSAF project, the International Maize and Wheat Improvement Center (CIMMYT) has developed locally appropriate agricultural extension materials to disseminate best management practices for maize, wheat and other crops. The government of Nepal has endorsed the project’s best management practices for rice, maize, wheat, tomato, cauliflower and onion.

These extension materials have information on integrated soil fertility management: a set of agricultural practices that integrates improved seed, mineral fertilizer use and soil organic matter management, all adapted to local conditions to improve agricultural productivity. They also serve to share information on the 4 Rs of fertilizer management stewardship: right source, right rate, right time and right placement.

CIMMYT and NSAF project partners are delivering these innovative extension materials to agrovets, cooperatives, extension agencies, development organizations and other intermediaries. They then use them to provide training to farmers in their working areas.

Training packages include pictorial aids, games, informative handouts, group activities, field guides, demonstrations, field visits and other physical learning tools. All the materials have been developed following an “active learning” framework. Training topics include the principles of integrated soil fertility management, soil pH and liming, crop-specific fertilizer application rates, planting methods, fertilizer splitting, methods of fertilizer placement, seed and fertilizer quality, handling considerations and postharvest practices.

“Training of extension workers and farmers on agricultural and plant nutrient related topics leads to an improvement in agronomic practices by farmers. Farmers that are trained and educated in best agronomic practices tend to realize high yields,” said Ramananda Gupta, Agronomist and Extension Specialist at the International Fertilizer Development Center (IFDC). CIMMYT is partnering with IFDC to implement the activities of the NSAF project related to fertilizer, including agricultural extension programs, policy support and market development.

All training materials have been field-tested with farmers, agro-dealers, government extension specialists and cooperatives. The training content has been reviewed by the Nepal Agricultural Research Center and Department of Agriculture. “The content of the best management practice materials are essential knowledge and skills farmers need to sustainably intensify production. Adoption of best management practices will significantly contribute in developing the rice sector as well as other related crops,” commented Ram Baran Yadaw, Rice Coordinator at the National Rice Research Program.

The NSAF project team is piloting the dissemination of improved technologies, skills and extension materials to farmers through local governments and private companies, using different tools and methods. The extension materials on best management practices will be publicly available, so improved seed and soil fertility technologies can be more accessible to farmers.

CIMMYT is also partnering with Viamo to adapt all the materials into an SMS and Interactive Voice Response (IVR) system to further scale up the program in the country, potentially reaching 12 million mobile phone subscribers.

The Nepal Seed and Fertilizer (NSAF) project promotes the use of improved seeds and integrated soil fertility management technologies along with effective and efficient extension programs across 21 “Zone of Influence” districts and in five earthquake-affected districts. The project is funded by the United States Agency for International Development (USAID), as part of the Feed the Future initiative. The project is led by International Maize and Wheat Improvement Center (CIMMYT), in collaboration with Nepal’s Ministry of Agricultural Development and partners including the International Fertilizer Development Center (IFDC) and the Center for Environment and Agricultural Research, Extension and Development (CEAPRED).

On December 5, we celebrate World Soil Day. This year the theme is “Be the solution to soil pollution.” Most of you may not have been aware that such a day even existed or perhaps even question the reason why the world even dedicates an entire day to celebrate soil. The authors of this article are soil scientists; we have devoted our professional careers to studying soil. Perhaps we are biased, but we use this opportunity to enlighten readers with a greater appreciation for the importance of this thin layer of our planet we call soil.

Humankind has a conflicting relationship with soil. In English, “dirt” and “dirty” are synonyms for unclean, calling a man or a woman “dirty” is a terrible insult. A baby’s dirty diapers are said to be “soiled.” But if we dig deeper into human consciousness, we find a different story.

For Hindus, the Panchtatva defines the universal laws of life. Everything, including life, is composed of five basic elements: Akash, space or sky; Vayu, air; Jal, water; Agni, fire; and Prithvi, earth or soil. In the Judeo-Christian tradition, the first two human beings on the planet were Adam and Eve. In Hebrew, the original language of the Bible’s Old Testament, the name Adam means “earth” or “soil” and Eve means “life.” These images and symbols portray that human life originally derived from soil.

It gets even deeper: The English terms “human” and “humanity” are rooted in the Greek word “humus,” the fertile black topsoil.

When we use the words “soil” and “dirt” as derogatory terms, we literally define ourselves as soil. Soil is important and here are a few reasons why.

Soil is absolutely critical for the survival of our species and of all living life on the planet. Over 90 percent of all food produced in the world comes from soil and a greater percentage of the world’s freshwater passes through soil.

Arguably, climate change is the greatest threat to our species. Despite mitigation efforts by the global community, soil is frequently forgotten. However, soil holds roughly two and a half times the amount of carbon held in the atmosphere and in all of the plants and animals combined.

Soil is also the greatest reservoir of biodiversity on the planet. In one pinch of soil, there are over 1 billion individual organisms and 1 million unique species, most of which we know almost nothing about. In one handful of soil, there are more living organisms than the total number of human beings that have ever walked on the planet. As all of our antibiotics have been derived from soil microorganisms, the secrets to fighting all kinds of diseases are just under your feet.

In Nepal, soil is deeply interrelated with culture. From birth to death, Nepalese use soil in many rituals: naming ceremonies, birthday celebrations, soiling on Ashar 15, local healing and medicine, etc.

The government of Nepal has set ambitious targets for increasing the levels of organic matter in soil. This is essential to ensure that the soils that have sustained Nepali civilization for centuries will continue to sustain future generations. We need to encourage farmers and land managers in Nepal to maintain terracing on steeply sloped lands to protect against soil erosion. It is also important to appropriately use agrochemicals, such as pesticides and inorganic fertilizers, to improve soil health and crop productivity.

Soil has been polluted by heavy metals, effluents from chemical industries, indiscriminate use of agrochemicals, urbanization without proper planning, networking of roads without considering the carrying capacity of the soil and other factors. So let’s not overlook the importance of soil. We need to value the cleansing properties of soil, particularly riverine soils, and prevent these areas from continuing as the dumping grounds and sewers of Kathmandu and other cities.

On this day, the day when we celebrate soil, take a moment to look under your feet and marvel at the beauty and complexity of soil.

If we take care of our soils, our soils will take care of us.

New digital maps to support soil fertility management in Nepal

KATHMANDU, Nepal (CIMMYT) — The International Maize and Wheat Improvement Center (CIMMYT) is working with Nepal’s Soil Management Directorate and the Nepal Agricultural Research Council (NARC) to aggregate historic soil data and, for the first time in the country, produce digital soil maps. The maps include information on soil PH, organic matter, total nitrogen, clay content and boron content. Digital soil mapping gives farmers and natural resource managers easy access to location-specific information on soil properties and nutrients, so they can make efficient and localized management decisions.

As part of CIMMYT’s Nepal Seed and Fertilizer (NSAF) project, researchers used new satellite imagery that enabled the resolution of the maps to be increased from 1×1 km to 250×250 m. They have updated the web portal to make it more user friendly and interactive. When loaded onto a smartphone, the map can retrieve the soil properties information from the user’s exact location if the user is within areas with data coverage. The project team is planning to produce maps for the whole country by the end of 2019.

CIMMYT scientist David Guerena talks about the role of the new digital maps to combat soil fertility problems in Nepal.

At a World Soil Day event in Nepal, CIMMYT soil scientist David Guerena presented the new digital soil maps to scientists, academics, policymakers and other attendees. Guerena explained the role this tool can play in combatting soil fertility problems in Nepal.

These interactive digital maps are not simply visualizations. They house the data and analytics which can be used to inform site-specific integrated soil fertility management recommendations.

The first high-resolution digital soil maps for the Terai region have been produced with support from the data assets from the National Land Use Project, developed by Nepal’s Ministry of Agriculture and Livestock Development. These maps will be used to guide field programming of the NSAF project, drive the development of market-led fertilizer products, and inform and update soil management recommendations. The government of Nepal can use the same information to align policy with the needs of farmers and the capacity of local private seed and fertilizer companies.

In 2017, 16 scientists from Nepal’s Soil Management Directorate, NARC and other institutions attended an advanced digital soil mapping workshop where they learned how to use different geostatistical methods for creating soil maps. This year, as part of the NSAF project, four NARC scientists attended a soil spectroscopy training workshop and learned about digitizing soil data management and using advanced spectral methods to convert soil information into fertilizer recommendations.

Soil data matters

Soil properties have a significant influence on crop growth and the yield response to management inputs. For farmers, having access to soil information can make a big difference in the adoption of integrated soil fertility management.

Farmer motivation and decision-making relies heavily on the perceived likeliness of obtaining a profitable return at minimized risk. This largely depends on the yield response to management inputs, such as improved seeds and fertilizers, which depends to a large extent on site-specific soil properties and variation in agro-ecological conditions. Therefore, quantitative estimates of the yield response to inputs at a given location are essential for estimating the risks associated with these investments.

The digital soil maps can be accessed at https://nsafmap.github.io/.

The Nepal Seed and Fertilizer project is funded by the United States Agency for International Development (USAID) and is a flagship project in Nepal. The objective of the NSAF is to build competitive and synergistic seed and fertilizer systems for inclusive and sustainable growth in agricultural productivity, business development and income generation in Nepal.

Let’s make hunger history

KATHMANDU, Nepal — I feel humbled and honored to have been chosen for the 2018 MAIZE-Asia Youth Innovators Award. I want to thank my father and brother for never clipping my wings and letting me fly high. I want to thank my mother, who despite having no education, not being able to read or write a single word, dreamed of having a scientist daughter. Everyone has a story and this is mine.

Due to my family’s poverty and the hardships faced during the civil war in Nepal, I had to leave school at grade 5 and was compelled to work as child labor in a local hotel to meet my family’s daily needs. I remember those difficult months where I used to cry every day, as the hotel was right across from the school and I wanted to study so badly but I was deprived from education due to my family’s condition. My life changed when a mountain climber staying at the hotel heard my story and generously decided to pay my school fees. I would go on to graduate top of my class.

Everyone has challenges. It is my dream to dedicate my life to fight the greatest challenge of all: hunger.

The amount of undernourished people in the world has been increasing. According to the Food and Agriculture Organization of the United Nations (FAO), over 820 million people face chronic food deprivation. Many of these people live in developing countries, including my home country, Nepal. About 6 million people, which is about 23% of Nepal’s population, are undernourished. Moreover, half of children under the age of five suffer from malnutrition in Nepal.

Increasing agricultural production, gender equity and awareness is crucial to meet sustainable development goals by 2030. As an agricultural student, I chose to focus on maize-based systems, as maize is a staple food crop and a major component of feed and fodder for farm animals. It is the second major crop in Nepal after rice — first in the hill region of Nepal — and can be a backbone for food security and a good source of income for resource-poor farmers.

Demand for maize is growing in Nepal, but production has remained stagnant. This is partly due to lack of knowledge on proper nutrient management and fertilizer use. In addition, due to the economic situation in Nepal, many men have been forced to migrate to find work and support their families, which has led to an increased “feminization” of agriculture. However, female farmers frequently have less access to information and resources that would help them to increase yields.

Since my undergraduate degree, I have carried out research on nutrient management in maize in the Eastern Terai region of Nepal, particularly focusing on women, to increase the maize production and income of smallholder farmers. My research involved the use of Nutrient Expert, a dynamic nutrient management tool based on site-specific nutrient management principles, to increase maize production and enhance soil quality without negatively affecting the environment. Regional fertilizer recommendations are often too broad and cannot take into account the soil quality of individual farmers’ field, as it varies greatly among fields, seasons and years. Applying the incorrect amount of fertilizer is costly to farmers and can negatively affect the environment and crop yields.

The Nutrient Expert app rapidly provides farm-specific fertilizer recommendations for nitrogen, phosphorus and potassium for crops in the presence or absence of soil testing results, contributing to dynamic nutrient management, increased productivity and net returns from crops for farmers. In the meantime, it helps to decrease the nitrogen and phosphorous leaching from the soil into rivers, which protects the water ecosystem both in wetlands and oceans. This technology is sustainable because it optimizes the use of nutrients in the soil for higher productivity and prevents the overuse of fertilizer. It decreases the farmer’s cost of production and is environmentally friendly. Further, my research showed that Nutrient Expert helped farmers to produce 86.6% more maize grain than their previous fertilizer practice.

Proper nutrient management is just one of the challenges facing agriculture today. To address these challenges and to create a world without hunger it is extremely important to work with and include young people. Effective extension tools to train and motivate young minds in research and create more interest in maize-based systems and farming is necessary for the overall adoption and proper utilization of improved varieties and technologies.

Samjhana Khanal was recently awarded the 2018 MAIZE-Asia Youth Innovators Award from the CGIAR Research Program on Maize (MAIZE) in the category of “Change Agent” for her research on the productivity and profitability of hybrid maize in Eastern Terai, Nepal. Using Nutrient Expert, a decision support tool, individual maize farmers can get specific soil nutrition and fertilizer recommendations, resulting in higher grain yield, productivity and profits.

An agricultural graduate, Khanal has founded and co-founded several local social organizations in Nepal to involve young minds in the development of innovative strategies to work towards sustainable agriculture and zero hunger. Her organizations support more than 285 households with community microfinance, help resource-poor farmers and assist women farmers.

The MAIZE-Asia Youth Innovators Awards aim to celebrate youth participation in maize-based agri-food systems and are sponsored by the CGIAR Research Program on Maize (MAIZE) in collaboration with Young Professionals for Agricultural Development (YPARD).
