This study was confined to analyze about the cost of cultivation of soyabean in Jhalawar district of Rajasthan. Soyabean is a valued crop and provides nutritious food for an expanding world population and will become increasingly important with climate change. Soyabean is looked upon not merely as means to supply food for humans and animals, but it also improves the soil fertility by fixing atmospheric nitrogen. Finally, 100 soyabean cultivators from selected villages were selected randomly in proportion to their total number in each size farm group for detailed study. Primary data were collected for agricultural year of 2022-23 and analyzed through various techniques and tools for drawing relevant conclusion. The study of cost of cultivation revealed that, on an average, total cost of cultivation of soyabean was ₹ 37613.83 per hectare. It was highest (₹ 38243.08 per hectare) on small farm and lowest (₹ 36865.49 per hectare) on large farm. Overall gross returns, net returns, farm business income and farm labour income were ₹55363.44, ₹ 17749.60, ₹33518.82 and ₹20242.15 per hectare. Cost of production was highest (₹ 3436.04 per quintal) for small farms and lowest for large farms (₹ 2965.85 per quintal) with an overall average of ₹3186.67 per quintal. On an average, output-input ratio was ₹147.19. For beneficial production of soyabean, it suggested that sufficient labour management in the field should be there. The cultivators should encourage giving an adequate place to soyabean in the cropping pattern at their farm through stakeholder like, Progressive Farmers.
