The hectare~(-1) physical input use was 63.83 kg seed, 11.60 MT manures, and chemical fertilizers 65.07 kg N, 11.71 kg P and 11.54 kg. K. Use of manures and fertilizers was very low as compared to recommended level. The hectare~(-1) input gap was 27.65 per cent for seed, 84.53 per cent for manure, 34.93 per cent for N, 76.59 per cent P and 76.93 per cent for K. The hectare~(-1) yield level of kharif rice on research station and demonstration farms was 50 and 40 q, respectively, while the sample farms average was 25.47 q. Consequently, the yield gap-I was 10 q, yield gap-II was 14.53 q and total yield gap 24.53 q. The per hectare cost of cultivation of kharif rice was Rs.36921.04 with gross returns of Rs.28135.00. The benefit cost ratio was 0.76. Within the different technology groups, it increased from 0.69 in low group, 0.71 in medium group and to 0.78 in high group. At overall level adoption of technologieson farmer field is low. Therefore, productivity is also low. Adoption of rice technologies released by the university by the farmers was 52.44 per cent resulted into yield gap to the extent of 49.06 per cent. Motivating of farmers for adoption of technologies to the fullest extent for maximizing returns from rice is recommended. 收起
