“…Inefficient application of these inputs directly increases the cost of production, leading to low economic gain from farming. Among the key factors, manure and fertilizer boast the highest share [85,86], resulting in great economic loss in the case of inefficient applications. Nepalese households rarely practice balanced fertilization to synchronize crop needs.…”

Optimizing N Fertilization for Increasing Yield and Profits of Rainfed Maize Grown under Sandy Loam Soil

The optimum dose of fertilizers for crops varies with soil, agro-ecology, and crop management practices. Optimizing application dose is critical to reduce nutrient loss to the environment and increase nitrogen use efficiency (NUE), crop yields, and economic return to farmers. An experiment was conducted to determine the optimum N dose for increasing maize (Zea mays L. cv, Manakamana-3) yield, NUE, and farm profits under rainfed conditions. Five levels of N (0, 60, 120, 180, and 240 kg ha−1), and a non-fertilized treatment were tested in a randomized complete block design with three replications. Effects of each treatment on yield and yield attributing traits, plant lodging and Sterility (plants with no cob or grain formation), NUE, and stay green trait of maize were recorded. Application of N above 120 kg ha−1 (N120) did not have any significant effects on yield and yield components. Nitrogen, at N120 and above, produced highly fertile plants (though sterility slightly increased at N180 and N240), higher N uptake, and lower dead leaf area (18–27%). N120 produced the highest agronomic; yield increase per unit of N application (AEN—26.89 kg grain kg−1 N) and physiological efficiency of N (PEN—42.67 kg grain kg−1 N uptake), and net benefit (USD 500.43). Considering agronomic, economic, and NUE factors, an N dose of 120 kg ha−1 was found optimum for the cultivation of rainfed maize (Manakamana-3) under sandy loam soil.

This study aimed to assess the profitability and resource use efficiency of maize seed production in the Rolpa district of Nepal. Primary data were collected from a sample of 67 maize-growing farmers involved in maize seed production, selected randomly from the sampling frame with a confidence level of 95% and a margin of error of 5%, using Raosoft. Additionally, secondary information was obtained through a review of relevant literature. Descriptive statistics and the Cobb-Douglas production function were employed for data analysis. The results indicated that maize seed production in the study area was profitable, as evidenced by a gross margin of 17,160.6 NRs./ha and a benefit-cost ratio of 1.12. The productivity level was estimated at 15.46 qtl/ha. Moreover, the return to scale of maize seed production was calculated to be 0.79, suggesting a decreasing return to scale. The analysis of allocative efficiency indices highlighted the need for optimizing resource allocation. Specifically, increasing costs on seed, chemical fertilizers, and management by 94.03%, 99.30%, and 60.25% respectively would lead to optimal resource allocation. Conversely, costs related to human labor, farmyard manure (FYM), and tillage should be reduced. This research contributes to a better understanding of the profitability and resource utilization in maize seed production in the Rolpa district of Nepal. The findings provide valuable insights for farmers and policymakers to make informed decisions regarding resource allocation and enhance the overall efficiency and sustainability of maize seed production in the region.

Resource use efficiency and constraints in cultivation of maize in Haryana

2021

The study was carried out during 2019 to determine the resource use efficiency and constraints faced in kharif maize growers in Karnal and Yamunanagar districts of Haryana. The experiment was conducted by surveying 60 maize cultivators selecting 30 respondents from each i.e. Karnal and Yamunanagar districts. Maize growers were personally interacted to extract relevant information. Cobb- Douglas production function was used to determine the resource use efficiency of maize cultivation to find out the most significant factor which influences the respondent; Henry Garrett's (1969) ranking technique was used. For optimal allocation of resource, it was observed that all the inputs in both the districts were less than unity, which indicates that all these inputs were over utilized in the respective district. It reflects that all the inputs were over utilized and use of these inputs needs to be curtailed to attain higher returns. Major constraints were watch and ward required to protect the crop from stray animals, lack of availability of suitable machines for threshing of maize, lack of availability of maize dryers and lack of availability of quality seed of recommended maize hybrids as specified by the maize growers.
