Effect of fertilizers and micronutrients on hoppers showed that the treatment 1.5 kg N + 1 kg P2O5 and 1 kg K2O along with Cu, Zn, B and S applied was most effective in checking multiplication of hopper population, whereas the treatment with 2 kg N only was least effective as maximum hopper population (20.06 hopper per panicle in 3rd observation) was recorded here. However, in rest of the treatments, hopper population was more or less equal to control. Maximum fruit set (189.75 and 139.25 fruits per 100 panicles) was observed in the treatment where 1.5 kg N, 1.0 kg P2O5 and 1 K2O were used along with Cu, Zn, B and S that was significantly different from control followed by the fruit set in recommended dosage. Minimum fruit set (116.00 and 105.25 per 100 panicles) was recorded in control. Fruit harvested and fruit weight were again highest (110.25 and 21 kg per 100 panicles) where 1.5 kg N, 1.0 kg P2O5 and 1 kg K2O were used along with Cu, Zn, B and S followed by fruit yield in recommended dosage. Lowest fruit number and fruit weight (100.25 and 16.30 kg per 100 panicles) were observed in treatment where only 2.0 kg N was used.
