Summary Fertilization of black gram with nitrogen (20 kg N/ha) in the form of urea produced a 32% increase in yield over control, and significantly improved nutritional quality of seeds by increasing crude protein, crude fat, methionine, calcium, phosphorus and iron contents without increasing polyphenols. The highest yield of black gram was obtained when plants were supplied with phosphorus at a rate of 40 kg P2O5/ha. Crude protein, crude fats, phosphorus and iron contents increased whereas calcium content decreased significantly at 40 kg P2O5/ha. A continuous increase in polyphenol content was observed with increasing levels of phosphorus but it was significantly increased at P rates above 40 kg/ha. Fertilization with N and P in a 1∶2 ratio at 20 kg N/ha and 40 kg P2O5/ha produced a 32% seed yield increase and improved the nutritional value of black gram seeds.
