The nitrogen content of paddy was higher (0.98 and 1.31% in straw and grain, respectively) due to application of super-optimal dose of NPK (T₉- 169:23:60 kg per acre). On the other hand, P and K content were higher (0.47 and 0.39%: 0.97 and 0.49%, respectively) with balanced (2:1:1) application of 90:45:46 kg per acre NPK. Significantly outstanding uptake of N (121.58 Kg ha^-1) was observed in grain as well as straw of paddy with 169:23:60 kg per acre NPK application. Whereas, higher uptake of P (43.76 Kg ha^-1), K (73.83 Kg ha^-1) were recorded in treatment T₇ with 90:46:45 Kg per acre NPK, respectively. With super-optimal dose of (169:23:60 kg per acre) NPK registered higher (88.64, 29.65, 24.33, 13.97, 12.22, 11.16 and 7.27% of leaf folder, caseworm, stem borer, gundhi bug, sheath rot, leaf spot and narrow leaf spot, respectively) insect pest and disease infestation. Inferior per cent invasion was documented with super optimal dose (27:12.5:15 kg per acre) of NPK (58.37, 14.75, 12.08, 7.35, 4.06, 6.27% of leaf folder, caseworm, stem borer, gundhi bug, sheath rot and leaf spot, respectively) except narrow leaf spot (3.30%) recorded least in optimal dose of NPK (T₆- 65:23:40 kg per acre).
