Effect of sulphur and biofertiliser use on yield and economic sustainability of mungbean (Vigna radiata L.)

A field trail was conducted at agriculture research farm, Lovely Professional University, Phagwara during Kharif season 2021 to study impact of sulphur and biofertilisers on yield and economic sustainability of mungbean. The experiment was conducted in Randomised Block Design with three replications. There were 9 treatments as follows: RDF, RDF + G1-Gypsum (20 kg/ha), RDF + G2-Gypsum (30 kg/ha), RDF + G1 + PSB, RDF + G2 + PSB, RDF + G1 + SOB, RDF + G2 + SOB, RDF + G1 + PSB + SOB and RDF + G2 + PSB + SOB. The results showed that amongst treatments, pods/plant (65.94), pod length (19.17 cm) and 1000-seed weight (61.73 g), seed yield (1597.67 kg ha-1) and biological yield (3565.87 kg ha-1) on per ha basis, gross returns (117000 ₹ ha-1) and B: C ratio (4.19) were significantly more in RDF + G2 + PSB + SOB treatment than rest of the treatments except RDF + G1 + PSB + SOB treatment. Use of biofertilisers and gypsum can be beneficial in terms of economics as well as for maintaining the soil fertility of the soil.
