COMPENSATORY BEHAVIOR OF PADDY CROP IN RESPONSE TO ADDITIONAL NITROGEN AND PHOSPHORUS APPLICATION WITH INCIDENCE OF YELLOW RICE STEM BORER

Abstract

As a parameter of the rice stem bores damage more Dead Heart percentage, White Head percentage, a high tillers percentage and a higher yield was recorded when fertilizer application was made at the rate of P-80 + N120 kg/ha. P-80 + N-120 kg/ha followed by P-70 + N-110, P-60 + N-100, P-50 + N-90 and P-40 + N-80 Kg/ha respectively. No significantly difference was recorded among each treatment. All the applications were found to provoke higher Dead Heart percentage, White Head percentage and tillers than the control. Overall the P-80 + N-120 kg/ha dose was found producing a significant higher yield than control.
