Effect of graded levels of potassium on yield and major nutrient uptake of black gram
Author(s): VK Adsure, SS Mane and SJ Supekar
Abstract: A field experiment was conducted in kharif season 2015-16 using black gram as a test crop to study the response of black gram to graded levels of potassium under drought condition with long dry spell in the Month of July and August. The results emerged out clearly indicated that various growth parameters like plant height, number of pods, number of nodules, fresh weight of nodules, total biomass production and dry matter and seed yield was increased due to application of potassium. It was inferred from the results that application of 25 kg N, 50 kg P2O5, or 30 kg K2O per hectare found superior over only N and P application i.e. RDF (25:50:00 N, P2O5 and K2O kg ha-1). The K application showed synergistic effects on other nutrients (N, P) uptake. Soil fertility was also found to be improved due to application of potassium to black gram.
