Abstract: On farm trials for two years (2016-17 and 2017-18) during the Rabi season, following Randomized Block Design was undertaken to evaluate the phosphorus use efficiency (PUE) as well as yield in boro rice. (Cv. Gotra Bidhan-1) with three replications having eight treatment combinations. The conventional tillage practice was undertaken during the study. Treatment T1 was control receiving recommended dose (RD) i.e. (N, K and without P application) and T2 to T8 has constant and RD of N and K with variables rates of P from different sources viz. inorganic and organic sources (FYM, Phosphocompost and Vermicompost).The maximum grain yield (6.25 ton ha-1 was obtained under T3 (variables rate of P application with constant dose of N and K) over that of other treatment combinations or control. The harvest index (%) of the crop was higher (T3) (35.26) over control or at par with T6 (34.49%) and T7 (34.87%) treatments. The Phosphorus Use Efficiency (PUE) of 34.43 was recorded under T7 in grain (Balance method, %). This might be due to the judicious application of organic manures and chemical fertilizers, providing greater stability in crop production, maintain improvements in soil fertility and enhance the nutrient use efficiency for growth and yield of rice.
