:This study was conducted to analysis the share of different expenditure incurred and profitability of crops in the North Eastern Dry Zone of Karnataka. A simple random sample of 30 farmers each under rainfed condition, borewell irrigation and canal irrigation are studied. Simple tabular analysis technique was used to estimate cost and returns of crops .The result of the study shows that human labour cost was accounted higher proportion (35-50 %) than other components followed by cost for bullock labour except in paddy where machine labour cost accounted (20%).The highest net returns were realized in paddy with borewell irrigation (Rs.49577/ha) followed by paddy with canal irrigation (Rs.44134 /ha), cotton with borewell irrigation (Rs.40442 /ha) compared to other crops in Raichur district.The benefit cost ratio for paddy cultivation was found higher (2.16) in case of canal irrigated due to less cost incurred (Rs. 38,004) compared to borewell irrigated paddy cultivation (Rs. 45,368) due to more energy cost for water pumping Rs.4110 (9.16 %).Among rainfed crops the most favourable returns per rupee cost was found cotton followed by redgram,chickpea and groundnut ranging from 1.72 to 1.61.

The study is on resource use efficiency of the major rainfed and irrigated crops in Northern dry zone (NDZ) of Karnataka, India in 2013−14. Bagalkot district was selected as a representative of Northern dry zone of Karnataka. The random sample of 90 farmers was chosen, 30 each belongs to cultivation under borewell irrigation, canal irrigation and rainfed condition, respectively. Cobb-Douglas production function was employed to assess the resource use efficiency in sugarcane under both borewell and canal irrigation and greengram under rainfed condition. DEA (Data envelope analysis) was used to find out the farm efficiencies of farmers in irrigated sugarcane, onion under borewell irrigation, sorghum and greengram were considered under rainfed condition for the analysis. The results indicated that MVP (Marginal value product) /MFC (Marginal factor cost) ratio for groundwater was less than one showed that there is no scope for further use of groundwater in the case of sugarcane under borewell irrigation. There is no scope for further use of human labour as ratio less than one in sugarcane under canal irrigation cultivation. While, in the case of rainfed greengram results depict that inefficient use of inputs such as fertilizers, human labour, seeds. DEA results represents that allocative efficiency of farmers in the study area were less than their technical efficiency. Therefore, this study concluded that there is a need to reallocate the resource in major crop cultivation in the study area and extension efforts has to initiate to guide farmers in order to increase their allocative efficiency with technical efficiency.
