Effect of phosphorus, sulphur and biofertilizer on yield and quality of greengram (Vigna radiata L. Wilczek) in loamy sand under Dryland condition

Abstract

The experiment was conducted during the Kharif season of the year 2018 at AICRP for Dry Land, Centre for natural resources management, Sadarkrushinagar datiwada agricultural university, Sardarkrushinagr, Gujarat. The results revealed that integrated application of 50 kg P2O5/ha + 20 kg S/ha + PSB registered significantly higher growth, yield attributes, seed and stover yield as well as protein content of greengram. But it was found at par with treatments viz., 40 kg P2O5/ha + 20 kg S and PSB, 30 kg P2O5/ha + 20 kg S/ha + PSB and 50 kg P2O5/ha + 20 kg S/ha. From these results, it could be concluded that for securing higher seed yield and net realization of greengram (cv. Gujarat Mungbean 4) raised on loamy sand under north Gujarat conditions, the crop should be fertilized with phosphorus @ 30 kg/ha, sulphur @ 20 kg/ha with PSB (phosphorus solubilizing bacteria) liquid biofertilizer along with recommended dose of N @ 20 kg/ha. By this way, 10 kg P2O5/ha can be saved than recommended dose of 40 kg P2O5/ha for greengram.
