“…Maize has high productivity and low environmental sensitivity which can help to provide sufficient food and reduce food scarcity (Mwambo et al, 2020). Maize is thought to have evolved from a wild version of pod corn that used to be and possibly is still, indigenous to South America's lowlands (Bryant, 2007). It is photo insensitive and can grow in both short and long day periods (Coles et al, 2010).…”

A study was undertaken on the economics of producing maize in the major maize-growing areas of Lekbeshi and Gurbhakot Municipality in Surkhet, Nepal. The study’s overarching goal was to assess and analyze the economics of producing maize in Surkhet A few specific goals were to identify the socio-demographic features of maize growers, as well as maize production and productivity. Many variables affect maize yield, including weed control, irrigation, insect and pest damage, and fertilizer use. Production economics examines the link between inputs and outputs, including labor, all economic investments, seeds, fertilizer, and irrigation, as well as outputs such as the price of produced maize. The required information was obtained with the help of a pre-tested questionnaire and 2 focus group discussions. Regarding the gender of the household head, most of them were male 75% and female 25% denoting a male-dominated society. Most of the respondents were female 52%. The fact that maize is primarily grown for self-consumption in this area makes it difficult to calculate costs, investments, returns, and benefits. Key problems that affect maize production include pests, diseases, marketing, fertilizer costs, low-quality seed, seed scarcity, and the lack of efficient technology. Fertilizers, seeds, and prepared fields were discovered to increase maize output. To improve maize production, key factors should be considered and limits reduced.
