Linseed and mustard are the most important prehistoric crops in the world, usually cultivated as major rabi oilseeds in India. The major constraints for low productivity are inadequate supply of nutrients and poor production practices. Technological demonstrations on linseed and mustard were conducted at 58 locations covering 24.4 ha area in participatory mode using improved linseed cultivar JLS 9, JLS 23 and mustard (pusa mahak) during 2007-08 to 2011-12. Line sowing was done after seed inoculation with azotobactor and PSB and soil test based NPK and sulphur doses were applied @ 60:40:20:40 kg ha-1. To prevent the crop from weed infestation pre-emergence herbicide was applied through flat fan nozzle knapsack sprayer after sowing in both the crops. Average seed yield of 1035.67 and 1187 kg ha-1 was recorded in improved cultivars under the technological frontline demonstrations of linseed and mustard respectively which was 66.68 and 86.2 percent higher over local check i.e. farmers’ practice (621.33 and 637.5 kg ha-1). The additional seed yield of linseed and mustard (414.33 and 549.5 kg ha-1) obtained with improved practice was correspondent to 50 and 84 percent of the farmers’ practice yield recorded in the respective crops which largely attributed to optimum potassium and sulphur application. The economic analysis of the frontline demonstrations on linseed and mustard gave the additional average net return of Rs. 11032.67 and 13886 ha-1 was obtained with an incremental benefit cost ratio of 1.06 and 1.45 over the farmers’ practice. The technology gap calculated in linseed and mustard showed the average yield gap of 114.33 and 563 kg ha-1 respectively which was close to the cultivars’ potential with 9.94 and 32.17 percent technology index in the frontline demonstrations. The average extension gap in the seed yield was observed 414.33 and 549.5kg ha-1 in linseed and mustard respectively.
