Abstract

Cultivation of pulses fit well to various cropping system and show climateresileince., Pulses are low external input demanding, can fix atmospheric nitrogen biologically and improve soil health. Among different pulses, green gram (Vigna radiata L.) is considered as an important crop in India. The crop responds to exogenous application of phosphorus and sulphur. Considering the above, a field trial was conducted to find the influence of phosphorus and sulphur on growth and productivity of green gram during rabi season of 2019-20 at Bagusala farm of Centurion University of Technology and Management. A split-plot design was considered for the experiment with three replication. The treatments were consisted of four levels of phosphorus (no application, 20, 40 and 60 kg P2O5/ha) in the main plot and three sulphur levels (15, 30 and 45 kg S/ha) in sub plot. The findings revealed that application at 60 kg P2O5/ha being statistically at par with 40 kg/ha P2O5 registered more growth parameters and yield attributes than the lower levels. The seed yield (1079.6 kg/ha) and stover yield (2025.1 kg/ha) were also noted with the application of 60 kg P2O5/ha and it remaind statistically at par with 40 kg P2O5/ha. However, 30 kg S/ha being statistically at par with 45 kg S/ha resulted in superior growth attributes, yield parameters and seed (979.2 kg/ha) and stover yield (1871.8 kg/ha) to lower levels. Further, the combination of 60 kg P2O5/ha and 30 kg S/ha produced significantly more grain yield (1211.3 kg/ha) than other treatment combinations. The study concludes that rabi green gram can be grown with 60 kg P2O5 and 30 kg S/ha for a better productivity.
