Abstract

Background: Being an efficient N- fixer, mungbean improve the soil fertility status and can thereby serve as a useful component in any viable cropping system in the country. PROM has to be a better source of phosphate application. Indian soils are deficient in organic carbon. Sulphur is mostly applied to oilseed and pulse crops found to benefit more than one crop in a sequence due to its significant residual response.
Methods: The investigation was conducted during kharif season of 2019 comprising five levels of phosphorus sources (Control, 16 kg P2O5/ha through DAP, 16 kg P2O5/ha through PROM, 32 kg P2O5/ha through DAP and 32 kg P2O5/ha through PROM) and three levels of sulphur (Control, 15 and 30 kg/ha) making 15 treatment combinations replicated three times in factorial randomized block design.
Result: Application of 32 kg P2O5/ha through PROM recorded significantly higher growth, yield attributes, yields as well as net returns ( 50440) with B:C ratio 2.93 as compared to 16 kg P2O5/ha through DAP, 16 kg P2O5/ha through PROM and 32 kg P2O5/ha through DAP. With regard to sulphur levels application of sulphur up to 30 kg/ha recorded significantly higher growth, yield attributes, yields as well net returns ( 46723) with B:C ratio 2.96 over control and 15 kg S/ha.
