Soil test based fertilizer prescriptions through integrated nutrient management using targeted yield approach for rice

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. The maximum Number of panicles m⁻², total filled grains panicle⁻¹, test weight, grain yield, straw yield, harvest Index and return per rupee investment were recorded with soil test based fertilizer recommendation with 10 t ha⁻¹ FYM application which was at par with soil test based fertilizer recommendation alone and 7.51 ha⁻¹ targeted yield recommendation along with FYM (T_g and T₀) and RDF with FYM (T). Grain yield of rice was significantly higher with soil test based fertilizer recommendation with 101 ha⁻¹ FYM application which was statistically at par with soil test based fertilizer recommendation alone (T) and 7.5 t ha⁻¹ targeted yield fertilizer recommendation with FYM (T_1L) compared to the rest of the treatments.
