Oilseed crops are the second most important determinant of Indian agricultural economy, next to cereals. Among oilseeds crops, Indian mustard (Brassica spp.) is grown in area of over 5.97 million hectares with production of 8.49 million tons and productivity of 14.1 q/ha (Ramoliya et al., 2022). The Department of Agriculture, Cooperation and Farmers' Welfare (DAC&FW) had launched "Cluster Frontline Demonstrations of Oilseeds" during 2015–16 under the National Mission on Oilseeds and Oil Palm (NMOOP) project in collaboration with Division of Agricultural Extension, ICAR, New Delhi. Among North Eastern states, average production rate of the crop through CFLD was found to be highest for Assam followed by with 11.87q/ha (ICAR-ATARI, 2019). Although the CFLD programme is doing well in the state of Tripura, the productivity was found to be lower by 4.36 q/ha with state average of 7.98 q/ha as compared to 12.34 q/ha yield in India (TERI, 2020). Keeping in view of the above, the following research is being proposed with the following objectives viz., (1) To assess the extent of adoption of CFLD farmers regarding Rapeseed & Mustard production technologies; (2) To study the relationship of extent of adoption of CFLD farmers regarding Rapeseed &Mustard production technologies with selected variables; (3) To ascertain the problems faced by the farmers in adopting the technologies through CFLDs. The study was conducted under two CFLD clusters of selected KVKs in Tripura comprising a total of 50 respondents. To measure the extent of adoption, index developed by Kalyan (2019) was adapted. Chi square test of association and ordinal regression were used to analyze the relationship of extent of adoption of rapeseed and mustard production technologies with selected variables while Garett’s ranking technique was used to ascertain the problems. The study found that majority of the CFLD farmers had medium level of extent of adoption with majority (82%) having full adoption of recommended insect-pest management practices. The independent variables farming experience, extension contact, mass media exposure, social participation and training attended by CFLD farmers were found to be significantly contributing to the level of adoption. Lack of irrigation, lack of oil seed crushing machines and shortage of labour at the time of sowing was the most important problems faced by the CFLD farmers. The study suggests that better irrigation management to reduce water management issues along with provision of funds and resources for post harvest management should be facilitated by the policy makers to increase employment obtaining higher returns thereby enabling establishment of post harvest based cooperatives and arrangement of more trainings on usage of ICT based agro- advisory portals for small scale CFLD farmers.
