Abstract
The rice brown planthopper is a rice pest, which one is very harmful when the nitrogen fertilizer is applied at a higher rate. To evaluate the effect of brown plant hopper by using different fertilizers on transplanted basmati rice, a field experiment was conducted at the experimental farm of School of Agriculture, in Lovely Professional University, Punjab during Kharif season 2015–2016. The different fertilizer doses were used, and the experiment comprised of 15 treatments. The results showed that the nitrogen fertilizer did not harm to rice crop, but the attack of brown planthopper was icreased due to more succulent tissues of a rice plant. The nitrogen increased the photosynthesis effect and ratio in the plant due to more production of chlorophyll. In case of another fertilizer P and K (P2O5 and K2O) are not promoting but also nor affecting to insect/pests attack. Zinc sulfate proved that its effect was much positive towards crop because the zinc sulfate making less susceptibility of plants to pest attack at all doses. The rice crop was showed highest brown plant hopper attack at 50 kg ha-1 of nitrogen and also showed maximum plant height, number of tillers, panicles/plant, and 1000 grain weight. Maximum grain and straw yield (7093 kg/ha, 8753 kg/ha) was recorded in T9 where N- 50, P-40 kg ha-1 was applied. The grain yield and straw yield was recorded maximum in treated plots as compared to the control.
