Effect of Phosphorus and PSB on Growth, Yield and Quality of Blackgram [Vigna mungo (L.) in Inceptisol

Abstract

A field experiment entitled “Effect of phosphorus and PSB on growth, nutrient content, uptake, yield and quality of black gram (Vigna mungo L.) in Inceptisol.” was carried out during the Kharif season 2017, at departmental farm of Soil Science and Agricultural Chemistry, College of Agriculture, Latur. The experiment was laid out in RBD with 10 treatment combination along with three replications. The results of field trial on response of black gram to application of different levels of phosphorus and PSB showed beneficial effect on growth, yield and quality of black gram. The growth parameter viz. nodulation, root length and chlorophyll content significantly improved due to application of 100% N + 60 kg P2O5 ha-1 + PSB followed by application of 100% N + 50 kg P2O5 ha-1 + PSB. Application of 100% N + 60 kg P2O5 ha-1 + PSB was found to be superior for increase in grain and straw yield followed by 100% N + 50 kg P2O5 ha-1 + PSB of black gram and also improve the quality of black gram seed in terms of test weight, protein content and protein yield. Among the treatments, application of 60 kg P2O5 ha-1 combination along with PSB inoculation showed superiority over all the treatments for improving yield and quality of black gram grown on inceptisol. Thus, it can be concluded that the application of P (60 kg P2O5 ha-1) in combination with PSB recorded statistically superior in growth, yield and quality of black gram as compared to alone application of different levels of P on low P content soils of inceptisol.
