The study was based on primary data from 473 lentil farmers selected randomly to analyze productivity, profitability, efficiency, and sensitivity of lentil farms in Nepal. Methods like benefit–cost, break‐even, margin safety, and sensitivity analysis, scaling technique, Cobb–Douglas type of production function, and stochastic frontier were adopted to derive farm economics, allocative, and cost efficiency levels. With average productivity of 672 kg/ha, lentil farmers in the study area were earning about 41% profit as of gross return with a profitability index of 0.78. About 45% margin of safety and estimates of benefit–cost ratio above one on all sensitivity measures is indicative of low risk and robust enterprise. Resources allocated in lentil production were found inefficient, and to achieve maximum return, expenses on land preparation, seed, nutrient, and plant protection cum irrigation should be increased by 27.6%, 80%, 33.1%, and 97%, respectively. Similarly, expenses on labor and harvesting activities need to be decreased by 30.1% and 23.6%. Labor cost and seed cost were the most important variables, and a 1% increase would surge the total production costs by 0.42% and 0.19%, respectively. The cost efficiency was estimated as 1.137 mean value, meaning that over 13.7% of the costs in lentil farms is wasted while comparing best‐practiced farm. Only about 48% of farms is fairly efficient at efficiency levels 1.0 to 1.09, but the majority is inefficient, which needs to minimize the waste of resources. Although suffering from climatic risks and production‐related problems, lentil enterprise is profitable, less risky, less sensitive, and fairly to inefficient in resource use. Wise attention is need on the part of farm management and resource utilization. Farmers are suggested to maintain farm size around 0.5 ha or below 1 ha, use only improved varietal seed, cut labor expenses with the use of machinery, and perform adequate tillage during sowing followed by effective disease management practices.

Teosinte (Euchlaena mexicana L.) is a popular herbage crop in Nepal. Although farmers produce teosinte seeds, management for maximizing seed yield is unknown. A study was undertaken to investigate teosinte seed yield in order to explore the seed production potential of teosinte for maximizing herbage yield. There were four different sowing dates (30 March, 30 April, 30 May and 30 June), four seed rates (20, 40, 60 and 80 kgha⁻¹) and three herbage cuttings (nil, once at 45 days after sowing (DAS), twice at 45 and 75 DAS) arranged in a split-split plot design. In both years, the highest seed yield was obtained from the two earliest sowings because they had taller plants, more tillers, a higher leaf area index (LAI) and more cobs per plant, ears per cob and seeds per ear than later sown plants. In 2017, seed yield did not differ among the seed rates because of adverse climatic conditions; however, in 2018 the two lower seed rates out yielded the two highest seed rates. Cutting twice significantly reduced seed yield in both years; one cut did not reduce seed yield in 2017 but it did so in 2018. These results suggest teosinte seed crops should be sown early at a seed rate between 20 to 40 kgha⁻¹. An economic analysis indicated that the traditional farmer practice of taking one herbage cut from their seed crop would not affect the gross margin.
