Harnessing the benefits of commercial agriculture

Rajendra Kathariya, a 41-year-old resident of Joshipur-2 in Kailali district, far-west of Kathmandu, has transformed his life and that of his family of five through commercial agriculture. Despite many challenges, Rajendra has remained committed to achieving financial sustainability through enhanced farming practices. Over the last two years, his partnership with Nepal Seed and Fertilizer (NSAF) and CIMMYT, in collaboration with Nisrau Multipurpose Cooperative, a partner cooperative of NSAF, has been instrumental in his success. 

Moving from traditional to modern farming

Previously, Rajendra cultivated cereal crops using traditional methods which often led to food crises for his family. However, he has now shifted to cultivating various crops throughout the year using modern farming techniques on his 1.02 ha of land and an additional 2.71 ha which he has leased. 

“Before NSAF’s support, we only cultivated two crops per year. Now we harvest three crops and are considering commercial maize production,” Rajendra said. 

Remarkable achievements in crop production

Last year, Rajendra cultivated rice on 3.72 ha, yielding 8.8 metric tons (t) worth NPR 250,000 (US $1,880.71). Similarly, he sold 3.8t of spring maize from 1.35 ha, earning NPR 110,000 (US $827.51). This year, he expanded maize cultivation to 2.03 ha, with an expected income of NPR 200,000 (US $1,504.57). His potato crop yielded 5.5t worth NPR 125,000 (US $940.35), with an additional 5.5t stored for future sale. 

In addition to crops, Rajendra has established a pig farm, earning NPR 400,000 (US $3,009.13) in 2023 from selling pigs. He received a feed-making machine for pigs from NSAF, under its support to agribusiness Micro, Small and Medium Enterprises (MSMEs).  

Embracing modern technology and techniques

Rajendra uses both organic and chemical fertilizers and follows improved farming techniques such as hybrid seeds, line sowing, and machinery use. He owns a mini tiller and rents other machinery as needed. This year, with support from NSAF, he used a drone to spray fertilizer on his spring maize, significantly reducing labor and time. 

“I have viewed videos of drones spraying fertilizer but never imagined it happening on my spring maize land. As a demonstration, 0.57 ha was used for nano urea spraying. The task was completed within five minutes of the drone taking flight. Similarly, I was astonished to learn that a drone can cover 2.02 ha in a mere 20 minutes,” he shared. 

Intercropping and future plans

Rajendra has also implemented intercropping, combining maize with legumes on a 0.10-hectare plot. “Spring maize-legume intercropping is productive and effective for farmers such as me. We can make a profit from legumes, as well as spring maize. I will continue using this practice in the future,” he said. 

Financial investments and community impact

The profits from agriculture have helped Rajendra to manage his household comfortably. He can now provide education for his four children, manage household expenses, and also pay the loan that he had taken for his household expenses. In addition, he recently invested NPR 250,000 (US $1,880.71) to build a new pig shed. He also sells his produce in local markets at Joshipur, Kailali.  

“I have travelled a long way from being a subsistence farmer to engaging in commercial farming. This shift from traditional to improved farming technologies has been made possible with the support of NSAF/CIMMYT. I am grateful for their assistance and encouragement,” Rajendra said. 

Vision for sustainability

Rajendra’s story reflects his dedication and hard work. “I was working as a daily wage laborer in India, hoping to secure a promising future for my children. Today, I can achieve complete sustainability through agriculture and provide quality education and a better life for my children,” he shared.

Wheat pathogen surveillance system set to expand through new investment

One of the world’s largest crop pathogen surveillance systems is set to expand its analytic and knowledge systems capacity to protect wheat productivity in food vulnerable areas of East Africa and South Asia.

Researchers announced the Wheat Disease Early Warning Advisory System (Wheat DEWAS), funded through a $7.3 million grant from the Bill & Melinda Gates Foundation and the United Kingdom’s Foreign, Commonwealth & Development Office, to enhance crop resilience to wheat diseases.

The project is led by David Hodson, principal scientist at CIMMYT, and Maricelis Acevedo, research professor of global development and plant pathology at Cornell University’s College of Agriculture and Life Sciences. This initiative brings together research expertise from 23 research and academic organizations from sub-Saharan Africa, South Asia, Europe, the United States and Mexico.

Wheat DEWAS aims to be an open and scalable system capable of tracking important pathogen strains. The system builds on existing capabilities developed by the research team to provide near-real-time model-based risk forecasts and resulting in accurate, timely and actionable advice to farmers. As plant pathogens continue to evolve and threaten global food production, the system strengthens the capacity of countries to respond in a proactive manner to transboundary wheat diseases.

The system focuses on the two major fungal pathogens of wheat known as rust and blast diseases. Rust diseases, named for a rust-like appearance on infected plants, are hyper-variable and can significantly reduce crop yields when they attack. The fungus releases trillions of spores that can ride wind currents across national borders and continents and spread devastating epidemics quickly over vast areas.

Wheat blast, caused by the fungus Magnaporte oryzae Tritici, is an increasing threat to wheat production, following detection in both Bangladesh and Zambia. The fungus spreads over short distances and through the planting of infected seeds. Grains of infected plants shrivel within a week of first symptoms, providing little time for farmers to take preventative actions. Most wheat grown in the world has limited resistance to wheat blast.

“New wheat pathogen variants are constantly evolving and are spreading rapidly on a global scale,” said Hodson, principal investigator for Wheat DEWAS. “Complete crop losses in some of the most food vulnerable areas of the world are possible under favorable epidemiological conditions. Vigilance coupled with pathogen-informed breeding strategies are essential to prevent wheat disease epidemics. Improved monitoring, early warning and advisory approaches are an important component for safeguarding food supplies.”

Previous long-term investments in rust pathogen surveillance, modelling, and diagnostics built one of the largest operational global surveillance and monitoring system for any crop disease. The research permitted the development of functioning prototypes of advanced early warning advisory systems (EWAS) in East Africa and South Asia. Wheat DEWAS seeks to improve on that foundation to build a scalable, integrated, and sustainable solution that can provide improved advanced timely warning of vulnerability to emerging and migrating wheat diseases.

“The impact of these diseases is greatest on small-scale producers, negatively affecting livelihoods, income, and food security,” Acevedo said. “Ultimately, with this project we aim to maximize opportunities for smallholder farmers to benefit from hyper-local analytic and knowledge systems to protect wheat productivity.”

The system has already proven successful, contributing to prevention of a potential rust outbreak in Ethiopia in 2021. At that time, the early warning and global monitoring detected a new yellow rust strain with high epidemic potential. Risk mapping and real-time early forecasting identified the risk and allowed a timely and effective response by farmers and officials. That growing season ended up being a production record-breaker for Ethiopian wheat farmers.

While wheat is the major focus of the system, pathogens with similar biology and dispersal modes exist for all major crops. Discoveries made in the wheat system could provide essential infrastructure, methods for data collection and analysis to aid interventions that will be relevant to other crops.
