Effect of phosphorus and sulphur on nutrient content and uptake of summer groundnut

Abstract

A field experiment was conducted at Agronomy Instructional Farm, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during summer 2019 in loamy sand soil. The experiment consisted of two levels of phosphorus (25 and 50 kg/ha), sulphur (20 and 40 kg/ha) and three bio-fertilizers (Phosphorus solubilizing bacteria, Sulphur oxidizing bacteria, Phosphorus solubilizing bacteria + Sulphur oxidizing bacteria) with four replications in randomized block design with factorial concept. Nutrient content and uptake of nitrogen, phosphorus and sulphur found significantly superior with application of 50 kg P2O5/ha and 40 kg S/ha than lower levels of 25 kg P2O5/ha and 20 kg S/ha. Inoculation of kernels with PSB + SOB significantly improved nutrient content and uptake than inoculation with SOB only and was at par with treatment PSB.
