A field experiment was conducted at the Agricultural College farm, Bapatla, during kharif and rabi 2017-18 and 2018-19. The experiment was conducted with variety BPT-5204 in a Randomized Block Design with ten treatments and three replications. Uptake and content of N, P and K in grain and straw at harvest were found significantly higher with the treatments that received soil test-based fertilizer recommendation with 10 t ha-1 FYM application, followed by soil test-based fertilizer recommendation (T2). Fertilizer use efficiency (FUE) was significantly the highest with application of 5.5 t ha-1 target yield recommendation with FYM (T8) compared to all other treatments. Grain yield of rice was significantly higher with soil test-based fertilizer recommendation with 10 t ha-1 FYM application which was statistically at par with soil test-based fertilizer recommendation alone (T2) and 7.5 t ha-1 targeted yield fertilizer recommendation with FYM (T10) compared to the rest of the treatments.
