Nitrogen and silicon have been considered beneficial for plant growth and plant health. To assess the effects of nitrogen and silicon on yield attributes and host plant resistance to blast disease in rice, three N levels (N1: 120, N2: 150, N3: 180 kg/ha) and four Si applications (Si0: Control, Si1: 5%, Si2: 10% and Si3:15%) were used in a factorial experiment in completely randomised block design with four replications. The yield attributes viz., the number of panicles m-2 and panicle weight, biological yield and harvest index were significantly highest with 120kg N/ha and 15% Si. Leaf blast and neck blast incidence increased with increase in level of nitrogen whereas it decreased with increased level of Si. Two year study leads to conclusion that treatment combination N1Si3 (120kgN ha-1 with 15%Si) proved to suitable and economically feasible for increasing yield and disease resistance in transplanted rice under temperate Kashmir conditions.
