Cereal crops have played major roles in addressing food security issues in Nepal. In recent years there have been fluctuations in crop production and demands situations due to various reasons. Thus, the present study aims to analyze the dynamics of major cereals productivity in Nepal from 1995 to 2014. Focus group discussions were done in mid-hills and tarai of Nepal in 2015. Percentage change, compound growth rate, annual rate of change, coefficient of variation, instability index were calculated to analyze results. The result shows that the area, production and productivity of major cereals had an increasing trend over the study period. The major factors contributing on productivity increase in cereal crops were irrigation facilities, use of improved and hybrid seeds, chemical fertilizer and better technical knowhow among the farmers. For effective adoption of research outputs to improve the productivity emphasis should also be given on promotion of public private partnership (PPP) in research and development.
Nepal is one of the top twenty countries where potato contributes substantially for the human diet. Enhancing adoption of improved potato varieties could impact on farmer's income, household food and nutritional security. As such, using a multistage sampling procedure, a study was conducted to assess the determinants of improved potato varieties adoption in Nepal covering 180 samples in four districts, two in hills and two in Tarai region. The study revealed that; Kavre and Bardiya districts in the hills and Tarai, respectively, were dominated by improved potato varieties adoption. On the other hand, Dhankuta and Jhapa in the hills and Tarai, respectively, were dominated by local potato varieties adoption. The informal seed sources followed by agro-vet and market were the major sources for improved varietal adoption. Farmers' accesses to training and formal seed sources were important factor determining improved potato varietal adoption. However, households with larger farm size were less likely to allocate more area for improved potato varieties as many of farmers were reluctant to take potato cultivation as agri-business and still follow subsistence farming. Potato R&D programs, therefore, need to strengthen formal seed system to enhance access to quality potato seeds and build producer's capacity through regular training and exposer visits in order to improve adoption of improved potato varieties in Nepal.
Background: Wheat is the third important cereal after rice and maize in Nepal. Its yield suffers from several factors such as lack of reliable irrigation, inclement weather, incidence of disease and lack of improved technology. New virulence race Ug99 (Uganda-99) has threatened all available commercial wheat varieties around the world and Asia. Some of the popular varieties of wheat in Nepal are also getting susceptible to different diseases. Vijay is one of the recently released first Ug99-resistant improved wheat varieties for Terai region in Nepal. Nepal has put special emphasis on the seed production and diffusion of this variety to promote rapidly in the farmers' fields to mitigate the potential epidemics of newly emerging pathotype of stem rust (Ug99). This variety is being promoted by several organizations and seed companies' before and after its release. Therefore, this study was undertaken to know the seed supply of Vijay and identify the factors that are contributing for its commercialization.Methods: Sunsari, Morang, Rupandehi, Banke and Kailali districts were selected purposely representing Eastern, Western, Mid-western and Far-Western Terai regions of Nepal, respectively. Seed companies, agro-vets (input dealers) and cooperatives involved in Vijay seed multiplication and distribution in the respective districts were selected for the purpose of the study. From the list of agro-vets in respective study sites, a total of 87 wheat seed selling agro-vets were selected randomly as a sample. The sample survey covered 44% of the target population in both categories (dealers and non-dealers of national seed company). Out of total samples, 40% were national seed company dealer agro-vets, while 60% were non-dealers. Multivariate regression analysis was used to find out different factors responsible for commercialization of Vijay seed. Results:Results indicate that about 67% of the agro-vets were involved in Vijay seed trading and their average time of involvement was 2.65 years. Majority of the agro-vets perceived this variety performed better than other existing popular varieties such as Gautam, Bhrikuti, Aditya and Nepal 297. However, there was still gap in timely supply of the seed. Based on the estimated Certified-1 seed production in 2015/16, Vijay must cover 56.88% (11,943 ha) of total wheat area in Terai, but share of Vijay seed was about 22% of the total wheat seed sold by agro-vets in 2015/16. Nevertheless, it seems that this variety is getting popular in the study area compared to other improved wheat varieties in short time period. The factors influencing commercialization of Vijay were: agro-vets having dealership of national seed company, perception on comparative better performance of Vijay with Nepal 297, total quantity of wheat seed sold by agro-vets and total business transaction of the agro-vets. Moreover, other factors such as pre-release multiplication of Vijay variety by private seed companies and participation on seed related training have found positive contribution on its commercializati...
Sustainable intensification of agriculture is a good approach for reducing the yield gap without exacerbating the current condition of the environmental components, which is a big challenge for agriculture in the modern world. This review provides a summary of the role and approaches of sustainable intensification in agriculture which offer ways to increase crop production and create long-term sustainability in agriculture production. The current demand for food has continued to rise as a result of the world's rapidly increasing population. In order to increase crop/food production, agricultural systems should be intensified by more sustainable practices, as well as by reforming existing production systems/techniques and diversifying them into newer and more profitable enterprises. Despite the heavy use of inputs, farmers have recently been unable to achieve optimal crop yields. The judicious use of agricultural inputs, combined with improved management techniques, is important for advancing sustainable intensification. New scientific techniques in agronomic practices, as well as improved farm mechanization, are helping to boost resource use efficiency in sustainable crop production. The sustainable agricultural intensification is necessary to increase the agricultural productivity under the changing and adverse climatic conditions while maintaining healthy production practices.
This study analyses the gaps and issues in the production and distribution system of maize seed in Nepal. A total of 682 households were surveyed in 2017 by employing multistage random sampling with probability proportionate to size by representing different (tarai and hill) agro-ecological zones. Twelve focus group discussions (FGDs) and four key informant interviews (KII) were also carried out. Results showed that the old varieties like Rampur Composite and Manakamana-3 are still popular in the farmers' fields. The cost of seed production was about 48% and the profit of the producer was 18% of the consumer price. The share of wholesalers was 15% of the consumer price whereas it was 19% for retailer/agro-vet. The average total cost of production was found to be $1392/ha and gross income was $1925/ha with the 1.38 average B: C ratio; it is, therefore, a lucrative enterprise. Out of a total of 27 released varieties, only 12 varieties have been used in seed production. Results revealed that 83% of the farmers cultivate open-pollinated maize varieties whereas 17% of them cultivate hybrid maize varieties. Seventy-five per cent of seed was from a formal source. The maize productivity, hybrid maize area, and seed replacement were below the targets set in Nepals’ National Seed Vision, a policy document of the government. Focus on the production of nucleus and breeder seed by Government research farms and use of these seeds by private seed companies and community seed producing groups to produce next generation foundation seeds are urgently required. Equally important is enabling private and community-based organizations to produce hybrid seeds of the crop.
This study was undertaken in 2016 to analyze the production and utilization of maize in Nepal. Sixty maize growers from Kavre and Lamjung districts were selected using purposive, cluster and simple random sampling techniques. Similarly, six feed industries and five maize experts from Chitwan district were also interviewed. Study shows 56% of the total areas were used for maize production and 50% of the maize areas were covered by hybrid maize. There was no practice of contract maize production. The results revealed that 60%, 25% and 3% of the grain were used for animal feed, food and seed respectively in hill districts. Whereas the remaining amount of the maize (12%) was sold to the different buyers. The proportion of maize feed supply to different animals in the study area was varying. Result shows that at least 1.5 million tons of maize is required only to the feed industries affiliated with national feed industry association in Nepal. Similarly, out of total maize used in feed production, 87% of the maize was imported from India each year by feed industries. Analysis shows negative correlation between scale of feed production and use of domestic maize due to unavailability of required quantity of maize in time. The major pre-condition of feed industries for maize buying was moisture content which must be equal or less than 14%. Very little or no inert materials and physical injury, free from fungal attack and bigger size were also the criteria for maize buying. However, some of the feed industries were also thinking about protein and amino acid contents. Result shows 13% and 8.5% increasing demand of poultry feed and animal feed, respectively over the last five year in Nepal. Most likely, maize is known as a means of food security in Nepal, however, in the context of changing utilization patterns at the farm level and also tremendous increasing demand of maize at the industry level suggest to give more focus on development and dissemination of maize varieties that can contribute to the feed security issues as well.
Maize is the second most important crop after rice in terms of area and production in Nepal. This article analyzes the technical efficiency and its determinants of hybrid maize production in eastern Nepal. Using a randomly selected data from 98 farmers (41 from Morang and 57 from Sunsari) in eastern Nepal, the study employed a stochastic frontier production model to find the production elasticity coefficients of inputs, determinants of efficiency and technical efficiency of hybrid maize farmers. The results showed that maize production responds positively to increase in amount of urea, DAP and the area planted, where as it is negative to seed quantity. The study indicate that farmers are not technically efficient with a mean technical efficiency 79 %. Socioeconomic variable age had a negative and significant while the household size had a positive and significant related to maize output. The younger farmers were observed more technically efficient than older farmers. Larger the members in the household higher the maize production. It is recommended that farmers should increase their fertilizer dose and farm size while they should decrease their seed rate for efficient production.
