Effect of phosphorus and sulphur on yield attributes, nutrient content and nutrient uptake of green gram in bundelkhand soil

This research was conducted with the aim to quantify the impact of Phosphorus and Sulphur of Green Gram (Vigna radiata L.) during winter season of 2014-15, at Agriculture experimental field, Nehru P.G. College Lalitpur, (U.P.). The treatments consisted of 4 Phosphorus levels (0, 30, 60 and 90 Kg P2O5 ha-1) and 4 sulphur levels (0, 10, 20 and 40 Kg S ha-1). The Pot experiment was laid out in randomized block design with three replications. Application of 90 kg P2O5 ha-1 and 40 kg S ha-1 significantly increased the Yield Attributes & Nutrient Content, Protein Content and Nutrient Uptake of Green Gram. The seed yield & straw yield at 20 kg S ha-1 was significant over control and nutrient uptake, content production at 40 kg S ha-1 was significant over control respectively. The maximum N, P, K and S contents and uptakes in Green Gram were recorded with 90 kg P2O5 and 40 kg S ha-1, respectively. The interaction between P and S had significant effect on yield and mineral composition of Green Gram and maximum yields were recorded under 60 kg P2O5 and 40 kg S ha-1 that was statistically at par with 90 kg P2O5 and 40 kg S ha-1.
