The field experiment on blackgram was carried out in summer, 2022 at the Crop Research Farm in the Department of Agronomy. The treatment consisted of three levels of biofertilizer no seed inoculation, Phosphate solubilizing bacteria (20 g/kg seeds), Rhizobium (30 g/kg seeds), three levels of kinetin (20, 30 and 40 ppm) foliar spray and a control. The experiment was set up using a Randomized Block Design with ten treatments and three replications. The variety black gold of black gram was sown in Zaid 2022. The results of the experiment revealed that foliar application of 40 ppm kinetin along with biofertilizers recorded significantly increased growth parameters viz., plant height (33.94 cm), number of branches (8.13), number of nodules per plant (36.80), plant dry weight (4.47 g/plant), crop growth rate (8.23 g/m2/day), relative growth rate (0.10 g/g/day). Same treatment also resulted in boosting yield and yield attributes viz., number of pods per plant (27.50), number of seeds per pod (8.07), test weight (40 g), seed yield (0.71 t/ha), stover yield (1.82 t/ha), harvesting index (28.09 %). In terms of gross returns (67450.00 INR/ha), net returns (44885.00 INR/ha), and the B:C (1.99), this treatment also demonstrated its favorable effects.
