A field experiment was conducted during the rainy (kharif) season of 1999, to evaluate the effect of rice husk and fertility levels on the nutrient content of rice (Oryza sativa L.). Rice husk @ 9.0 t/ha significantly influenced the potassium content in straw and grain. However, fertility levels (120, 60, 40,20 kg/ha of N, P2O2 K2O and ZnSO4 respectively) brought out highly significant changes in N, P and K content of rice plant. Rice husk and fertility levels create significant differences in grain and straw yield. Higher grain yield was found with 9.0 t husk/ha and it registerd 8.02% more grain yield over control. In case fertility levels, higher dose (120, 60, 40, 20 kg of N, P2O5K2O) depicted 44.45% greater yield than control.
