A field experiment entitled NPK uptake influenced by integrated nitrogen management in basmati rice (Oryza sativa L.) was conducted at Punjab Agricultural University, Ludhiana during kharif 2010. The experiment was conducted in randomized block design with 13 treatment combinations of chemical fertilizer, green manuring (GM) with Crotalaria juncea, farmyard manure (FYM) and organic preparations [OP (Jeevamrit and Panchagavya)] in four replications. The highest grain yield (34.9±0.54 q ha-1 ) was obtained with combined application of FYM and 50 per cent of recommended nitrogen (RN) followed by GM+FYM+OP (33.7 q ha-1 ) and GM+FYM (33.4±0.99 q ha-1 ). Straw yield (63.1 q ha-1 ) increased significantly (P<0.01) in treatment where FYM combined with 50 per cent of RN was applied. Among different nitrogen management treatments, the maximum N, P and K uptake in grain and straw were observed under treatment T8 (FYM +50 per cent of RN) viz. integrated nitrogen treatment followed by T11 (GM+FYM+OP) and T9 (GM+FYM). Thus, combined application of FYM @ 19.76 t ha-1- with reduced fertilizer dose (50 % of RN) increased the yield and NPK uptake in basmati rice.
