Helminthosporium leaf blight (HLB) is an explosive disease on plain and foot hill of Nepal. The severity of H LB is increased i n stress conditions. This experiment was conducted at National Wheat Research Program, Bhairahawa i n 1997 and 1998 to explore the role of Major nutrients on HLB management. Wheat was planted at Nitrogen (N), Phosphorus ( P) and Potash (K) deficit field in factorial RCB design with different combination of two level of potassium (0 and 50 kg K/ha) and four level of nitrogen (0, 50, 100 and 150 kg N/ha). …………………….
