Being one of the largest rape and mustard growing districts of Assam, in term of area of cultivation, Kokrajhar district was selected for the study. Two blocks namely Titaguri block and Gossaigaon block were randomly selected from the district. In the next stage, a total of four villages, i.e., 6 No. Basbari and Brahmapur villages from Titaguri block and Saraibil and Kachukata villages from Gossaigaon block were selected at random. At the last stage, 25 farmers from each village were randomly selected forming the primary data of 100 sample farmers. The framers were then categorised into marginal (< 1 ha), small (1-2 ha), medium (2-4 ha) and large (>4 ha) based on their land holdings. Secondary data were collected from the publication, Impact of Technologies on Oilseeds Production in North Eastern Region and Krishi Vigyan Kendra, Kokrajhar. The findings revealed that the sample farmers did not follow proper package of cultivation practices for rape and mustard. The results showed that the average cost of cultivation was estimated to be Rs. 29539.18 per hectare, which varied from Rs.26294 to Rs. 32711.39 per hectare. The results indicated that technical, allocative and economic efficiency of farms were respectively 94.23 percent, 90.83 percent and 87.72 percent on average. The yield gap analysis recorded 6.48 q/ha yield gap between the research station yield and average farm yield, 3.38 q/ha yield gap between demonstration yield and average farm yield and yield gap of 3.10 q/ha between progressive farm yield and average farm yield. The index of realized potential farm yield-II was estimated to be 64.03 percent on an average. Regression analysis showed that the gaps in input used between progressive farms and the sample farms needed to be reduced in order to narrow down the yield gap. In order to reduce the input gaps, farms needed to invest more on their inputs. The results of valuation of technical intervention showed that smaller farms had to invest more in inputs than the larger farms in order to increase their rape and mustard yield.EnglishThesis
