Agriculture is largely feminized in Nepal, where over 80% of women are employed in the sector. As a result of the skills gap caused by male out-migration, many women farmers are now making conscious efforts to learn techniques that can help improve yields and generate greater income â such as balanced fertilizer application â with support from the International Maize and Wheat Improvement Center (CIMMYT).
Studies have shown that many farmers lack knowledge of fertilizer management, but balanced fertilizer application using the right ratio of nutrients is key to helping crops thrive Through the Nepal Seed and Fertilizer (NSAF) project, CIMMYT researchers are working towards promoting precision nutrient management through multiple trials and demonstrations in farmersâ fields.
Through this initiative, Dharma Devi Chaudhary, a smallholder farmer from Kailali district, has been able to increase her annual earnings by adopting balanced fertilizer application in cauliflower cultivation â a key cash crop for the winter season in Nepalâs Terai region.
Her inspiration to use micronutrients such as boron came from the results she witnessed during a CIMMYT-supported demonstration conducted on her land in 2018. During the demonstration, Chaudhary learned the principles of the four âRsâ of nutrient stewardship: the right rate, the right time, the right source and the right placement of fertilizers. She became familiar with different types of fertilizer and the amount to be used, as well as the appropriate time and place to apply urea top-dressing, diammonium phosphate (DAP) and muriate of potash (MoP) for optimal utilization by the plant.
Chaudhary also learned how boron application can increase crop yields while helping prevent plant diseases, especially in cauliflower, where boron deficiency can lead to a disorder known as âdead heartâ and cause significant yield loss. This is particularly useful knowledge for farmers in Nepal, where the boron content in soil is generally low.

Benefitting from best practices
Cauliflower is cultivated on 615 hectares of land across Kailali and produces a yield of 15 tons per hectare â far less than the potential yield of 35-40 tons. As a standard practice, farmers in the area have been applying nitrogen, phosphorous and potassium (NPK) at a ratio of 27: 27.6: 9 kilograms per hectare and three tons of farmyard manure per hectare. During a CIMMYT-led demonstration on a small parcel of land, Chaudhary observed that balanced fertilizer application yielded about 64% more than when using her traditional practices, fetching her an income of $180 that season compared to her usual $109.
Following this demonstration, Chaudhary decided to independently cultivate cauliflower on a plot of 500 square meters, where she applied farmyard manure two weeks before transplantation and then used DAP, MOP, boron and zinc as a basal application during transplanting. She also applied urea in split doses, first at 25 days and then 50 days after transplantation. Using this technique, Chaudhary was able to yield 46 tons of cauliflower per hectare, nearly twice as much as was yielded by farmers using traditional practices. As a result, she was able to generate an income increase of $800 for her household, compared to the previous seasonâs earnings.
âI was able to buy education resources, clothing and more food supplies for my children with the additional income I earned from selling cauliflower last year,â said Chaudhary. âLearning about the benefits of using micronutrients is essential for smallholder farmers like me who are looking for ways to improve their farming business.â
Smallholder farmers tend to be risk averse, which can make technology adoption difficult. However, on-farm demonstrations help reduce the risks farmers perceive and facilitate new technology adoption easily by exhibiting encouraging results.
Chaudhary now serves as a lead farmer at Janasewa Krishak Multi-purpose Cooperative and supports the organization by disseminating knowledge on balanced fertilizer management practices to hundreds of farmers in her community. After seeing the impact of adopting the recommended techniques, the use of balanced fertilizer is reaping benefits for other farmers in her district, helping them achieve better income from higher crop yields and maintain soil fertility in their area.

Masuriya, a rural village in Nepalâs Gauriganga municipality, was one of the villages affected during the countryâs civil war which ran from 1996-2006. Since 2012, Bandana Joshi, chairperson of a local cooperative, has been encouraging women in her village to optimize fertilizer application to maximize plant growth and profitability, and improve livelihoods. However, her journey to this day was not an easy one.
In the years of the civil war, women in the villages like Masuriya faced the burden to make ends meet for their children and elderly family members, as most men fled in fear of war or migrated to earn income. It was during this time that Joshi and a group of 24 women who were operating a savings and credit firm realized that more women in their village needed monetary support to carry out their livelihood activities. They decided to expand their services and formed a cooperative to empower rural women and make finance available in the village. Their cooperative, Sana Kisan Sahakari Sanstha Limited, now has 1,186 women members, more than half of whom belong to marginalized communities â 514 Janajatis and 154 Dalits.
Many of the members are small commercial farmers, owning about 1.4 ha of land for farming as their sole source of income. Most have traditionally grown cereals such as rice and wheat alongside a few vegetables and had limited knowledge on cash crop farming and soil fertility management. They would produce and sell their surplus rice and wheat when they needed cash to buy groceries or pay household bills.

In October 2016, researchers from the International Maize and Wheat Improvement Centerâs (CIMMYT) Nepal Seed and Fertilizer (NSAF) project and the International Fertilizer Development Center (IFDC), launched an integrated soil fertility management (ISFM) program and worked alongside the cooperative to disseminate and encourage the use of ISFM technologies among its members. The purpose was to show farmers the benefits of ISFM â an integration of organic inputs and inorganic fertilizers with improved seeds â for rice, wheat and cauliflower cultivation, that includes balanced fertilizer application to increase yield. The project team conducted research trials and on-farm demonstrations on these crops as part of the initiative and built capacity through farmer field days and trainings on best management practices.
As a strategic entry point, the cooperative in coordination with female community volunteers helped implement the ISFM program. Women received training on the right source and amount of fertilizer that matches crop needs, and the right time and place to apply these fertilizers to maximize nutrient uptake and improve crop yields. NSAF researchers engaged with lead farmers and the cooperativeâs leadership to influence their acceptance of the new fertilizer application practices, and they in turn motivated the members to use balanced fertilizer application. In 2020, these activities have been critical in building awareness on balanced fertilizer application for more than 800 farmers on over 700 ha of land, with each household able to raise their crop productivity by at least 50% for vegetables and 25% for cereals.
Better soil, better harvest
So far, the use of balanced fertilizer application has benefited more than a hundred members of the cooperative by gaining an average income of $219 in a season from cultivating cauliflower â a cash crop in Nepalâs Terai region. This additional return has helped farmers to adequately feed an average family of 4.5 people for the entire year.
Dutrani Chaudhary, a cooperative member, said that she was able to raise cauliflower production by 64% by applying balanced fertilizers that supplied all the essential nutrients â nitrogen, phosphorus, potash and micro-nutrient boron. She earned about $238 from 0.033 ha of land, which is a much larger gain for any farmer from a single season. As well as boosting her pride and confidence, she can now contribute for her childrenâs school fees and household expenditures.
After witnessing positive results, many other farmers in the village started applying major nutrients using urea, DAP (Di-ammonium Phosphate) and MoP (Muriate of Potash) to increase crop productivity. In 2017, Joshi and her members noticed a sharp rise in fertilizer procurement from the cooperative among farmers resulting in almost double the sales compared to 2015. Prior to the projectâs agronomic literacy programs on soil fertility management, she sold merely 15 tons urea and 10 tons of DAP. Thereafter, fertilizer sales increased to 32.6 tons and 27.9 tons, for urea and DAP respectively, in just two years.
âFor the first time in 2018 we sold 500 kilograms of MoP since the cooperative established,â explained Joshi. MoP was never considered a priority by the farmers before and they rarely purchased it from the cooperative.

On the rise
Now more organized and well-equipped, the cooperative has started organizing programs this year on off-seasonal and seasonal vegetable cultivation on crops such as tomato, cauliflower and cucurbits that have aided around 150 member households. âWe have prioritized balanced fertilizer application in our vegetable production program,â says Madhuri Chaudhary, manager of the cooperative.
The woman-led rural institution has achieved remarkable success over the years by learning and adopting best agronomic practices including fertilizer application, planting and cultivation methods that helped increase crop productivity and household income. Having seen the benefits, male family members now encourage them to participate in agronomic literacy programs to acquire advanced knowledge and skills.
Joshi and her team of visionary women have been successful in setting up an inclusive new movement in Masuriya village, which has led to their active participation in development activities and decision-making roles not only at the household level but also in societal issues around womenâs rights. Passionate to learn new skills and grow financially independent, these rural women are confident in making their own decisions for themselves, their family and for the wider society. Although it started small, the cooperative has now boomed towards improving rural womenâs economic empowerment and sparking better livelihood opportunities in the area.
