Chemistry, College of Agriculture,Badnapur using red gram as a test crop to study the “Influence of graded levels of potassium on growth, yield and quality of red gram.” The experiment was laid out on Vertisols with six treatment combination, replicated four times in randomized block design. The treatment consists of Ti Absolute control (No fertilizer application), T2 RDF (25:50:25 N, P205 and K20 kg ha1), T3 (25 kg N+50 kg P205 + 15 kg K20 ha4), T4 (25kgN+50kg P205 + 30 kg K20 ha4), T5 (25kgN+50kg P2Os + 45 kg K20 ha4), T6 (25kgN+50kg P2Os + 60 kg K20 ha4). 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 ha50 kg P205 ha1 and 30 kg K20 ha 1 found superior over RDF( 25:50:25 N, P2Os and K20 kg ha'1) application in red gram. The K application showed synergistic effects with other nutrients (N, P). Soil fertility was also found to be improved due to application of potassium to red gram.ennullThesis
