摘要：Leaf rust (Puccinia triticina f. sp. tritici) is universal threat for wheat production. In present study, effect of sowing dates (30th Oct; 10th, 20th and 30th Nov) and NPK levels (N1-80Kg, N2- 100Kg, N3-60Kg, P1-58 Kg, P2-70Kg, P3-50Kg, K1-63Kg, K2-75, K3-55Kg) against leaf rust and their impact on 1000 grain were evaluated under Randomized Complete Block Design (RCBD) at Plant Pathology research area in University of Agriculture Faisalabad during 2009. Results showed that among 3 fertilizers, K exhibited significant result as compared to N, P and control for management of leaf rust and produced maximum 1000 grain weight. Among sowing dates, rust severity was minimum in early sown (30th Oct) and maximum in late sown (30th Nov). Thus early sowing with different levels of NPK has paramount importance to combat leaf rust severity effectively.
