Abstract:
A field trial was carried out at Crop Research Farm, Naini Agricultural Institute, Department of Agronomy, Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj during Zaid season, 2021 to study “Effect of phosphorus and sulphur on the growth and yield of summer Mungbean (Vigna radiata L.). The experiment was done in randomized block design with nine treatments replicated three times. Factors consisted of three levels of phosphorus in the form of DAP (40, 50, 60 kg/ha) and three levels of sulphur in the form of Gypsum (10, 15, 20 Kg/ha). The results revealed that application of 60 kg/ha Phosphorus + 20 kg/ha Sulphur recorded maximum plant height (43.25 cm), number of nodules/plant (29.93), plant dry weight (15.24 g), crop growth rate (13.31 g/m²/day),number of pods/plant (23.87), number of seeds/pod (8.73), test weight (37.63 g), seed yield (970.33 kg/ha), stover yield (1597.67 kg/ha) gross return (₹ 106736.3/ha), net return (₹ 63592.3/ha) and B: C ratio (1.47). Whereas maximum relative growth rate (0.035 g/g/day) was recorded with application of 40 kg/ha Phosphorus + 20 kg/ha Sulphur and highest harvest index (38.30%) was recorded with application of 50 kg Phosphorus/ha + 20 kg Sulphur/ha.
