The field study was carried out between Zaid 2022 and the Farm for Crop Research, Department of Agronomy, Prayagraj’s SHUATS is home to the Naini Agricultural Institute (UP) India. To study the Response of phosphorus and foliar application of zinc on growth and yield of blackgram. The factors consist of phosphorus at 30 kg/ha, 40 kg/ha, 50 kg/ha respectively foliar application of zinc at 0.1% at 20 DAS, 0.3% at 30 DAS, 0.5% at 40 DAS. Nine treatments were used, and each was repeated three times.  The experimental plot’s soil had a loamy sand texture and had a nearly neutral soil reaction. (pH 7.8), low in organic carbon (0.35%) accessible N (163.42 kg/ha), accessible P (21.96 kg/ha), and accessible K (256.48 kg/ha). Results revealed that the higher plant height (40.02 cm), higher number of root nodules per plant (24.00), higher number of branches per plant (6.66) higher plant dry weight (8.03 g/plant), higher number of pods per plant (20.00), higher number of seeds per pod (6.11), higher test weight (34.07 g), higher seed yield (1.39 t/ha), and higher stover yield (2.04 t/ha) were significantly influenced with the application of phosphorus 50 kg/ha along with zinc 0.5% at 40 DAS. Higher gross return (INR 111930.23/ha), higher net return (INR 80415.73/ha) and higher B:C ratio (2.55) were also recorded with the application of phosphorus 50 kg/ha along with zinc 0.5% at 40 DAS.
