abstract
A Field experiment was conducted at the Experimental Farm, Department of Agronomy, Annamalai University to study the effect of integrated nutrient management on the growth and yield of irrigated blackgram during February-April 2023. The experiment was laid out in Randomized Block Design (RBD) with twelve treatments replicated thrice by using blackgram variety ADT 5. Among the different treatments under study application of vermicompost @ 2.5 t ha^-1 + 100% P₂O₅ ha^-1 through PROM + TNAU Pulse wonder @ 5 kg ha^-1 foliar spray at peak flowering stage recorded highest values of all growth parameters viz., plant height (21.65, 32.94 and 37.22cm at 30DAS 45DAS and at harvest stage), number of branches plant^-1 (9.14), chlorophyll content (48.27), number of effective nodules plant^-1 (29.2), LAI at 50 DAS (3.98), Dry matter production (1397, 2178 and 3145 kg ha^-1 at 30 DAS, 45DAS and at harvest) of blackgram respectively.
