Abstract: An experiment was conducted during kharif 2015 at Agronomy Research Farm, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu (J&K), India to study the effect of graded levels of N, P & K on yield and nutrient uptake of fine rice (Oryza sativa) under sub-tropical conditions. Results revealed that, graded levels of P and K, highest grain (4091 kg ha-1) and straw yield (7242 kg ha-1) was recorded with P3K1 (35:15 kg ha-1 of P2O5 and K2O) though the difference was non-significant. Whereas, with N application highest grain (4214 kg ha-1) and straw yield (7475 kg ha-1) was recorded with 60 kg N ha-1 which was statistically at par with 50 kg ha-1. Graded levels of P and K not influence the nitrogen, phosphorus and potassium uptake but levels of N significantly improve NPK uptake by crop. Highest uptake of total NPK by grains as well as straw was recorded with application of 60 kg N ha-1 which was at par with 50 kg N ha-1.
