Effect of phosphorus and sulphur on nutrient content and uptake in Mungbean (Vigna radiate L.)

Abstract

A study was carried out at Agronomy Farm, college of agriculture, SKRAU, Bikaner during kharif season of 2016 to evaluate the effect of different levels of phosphorus and sulphur and their interactions on growth, yield attributes and nutrient concentration of mungbean. The experiment was laid out with twelve treatments combinations consisting of four levels of phosphorus (control, 15, 30 and 45 kg P2O5 ha-1) and three levels of sulphur (control, 20 and 40 kg S ha-1). The results revealed that uptake and content of nutrients increased significantly with increasing levels of phosphorus and sulphur. Application of 30 kg P2O5 ha-1 and 20 kg S ha-1 significantly increased the nitrogen, potassium, sulphur content and their uptake by seed and straw but highest was found with 45 kg P2O5 and 40 kg S. Whereas, the phosphorus content in seed and straw significantly increased with increasing levels of phosphorus up to 45 kg P2O5.
