The experiment was conducted in 20 replications with three technology options viz., TO₁: Farmers practice i.e. cultivation of Brown Gora, a local rice variety+10 q/ha FYM, TO₂: TO₁+NPK at 25:12.5:6.0 kg/ha and TO₃: TO₁+NPK at 50:25:12 kg/ha (Recommended dose of fertilizers). Results revealed that highest grain yield (15.12 q/ha) was obtained from the technology option with recommended dose of fertilizers (TO₃). It was 47.0 and 33.0% higher than the yield obtained under the technology options TO₁ and TO₂ respectively. When economics was taken into consideration it was found that the highest net return (Rs 4,976/ha) was recorded under technology option TO₃, which was statistically at par with the net return (Rs 3,363/ha) received under technology option TO₂. 收起
