During the Kharif season of 2022, an experiment was carried out to delve into the production potential and quality of black gram under the influence of phosphorus and different sowing dates. The treatment combinations from four levels of phosphorus i.e., P? (Control), P? (10 kg P?O? ha-1), P? (20 kg P?O? ha-1), P? (30 kg P?O? ha-1) and three dates of sowing i.e., D? (9?? July), D? (15?? July), D? (22?? July) were laid out in Factorial Randomized Block design and were replicated thrice. The results manifest that the use of 30 kg P?O? had a substantially higher number of pods plant-1 (21.96), number of seeds pod-1 (4.69), test weight (35.84 g), grain yield plot-1, (1.37 kg), grain yield (11.38 q ha-1), stover yield (27.33 q ha-1), harvest index (29.34%) and protein content (22.80%). The beneficial effect of sowing dates was also noticed and maximum values for the number of pods plant-1 (21.25), number of seeds pod-1 (4.40), test weight (35.01 g), grain yield plot-1, (1.27 kg), grain yield (10.56 q ha-1), stover yield (25.38 q ha-1), harvest index (29.22 %) and protein content (22.03 %) were obtained when the crop was sown on 9?? July. Therefore, it may be concluded that 30 kg P?O? ha-1 and sowing on 9?? July proved to be a better strategy to realize better production and higher protein content in the seeds of black gram
