An economic study of cost and returns of onion under different cultivation methods, broadcasting, line sowing and transplanting method. Primary data was collected from eighty onion farmers from Ballari and Koppal districts of Karnataka. Cost and returns were calculated along with Cobb Douglas production function and Garret ranking for the constraints were estimated. It was evident that the cost of cultivation and the gross returns per acre under the transplanted method was higher (?55,491/, ?1,84,742) as against the line sowing method (?40,294, ?99,996) and the broadcasting method (?37,257,?64,492).It was evident that the average yield of onion under the transplanting method was higher (138.59 q/acre) compared to the line sowing (115.36 q/acre) and broadcasting (93.12 q/acre) methods. There is a need to popularize the transplanting method among the farmers of the study area with the help of KVK's and, other line departments by organizing field days and demonstrations.
