Residual effect of fertilizer recommendations and organic manures imposed in kharif rice on succeeding rabi blackgram

Abstract

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 plant height and drymatter production and seed yield 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 7.5tha-1 targeted yield recommendation along with FYM (T5 and T10) and RDF with FYM (T6). seed yield of blackgram 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.
