A study was conducted with graded levels of potassium and sulphur on pigeon pea to assess the nutrient uptake, yield and quality at Agronomy Farm, College of Agriculture, Nagpur (M.S.) The data revealed that application of K and S levels significantly influenced the uptake of major and micronutrient in pigeon pea. High N and P uptake was observed due to application of 30 kg potassium and 20 kg sulphur per hectare. Potassium uptake was increased significantly with increasing the levels of K. The highest K uptake was noticed in 45 kg K and 20 kg S per hectare combination. The recovery of NPK was higher in 30 kg potassium per hectare. Due to increased level of potassium and sulpur there was no adverse effect on calcium assimilation and highest uptake of calcium was observed in the application 30 kg K and 20 kg S per hectare. The optimum supply of K and S improves the uptake of micronutrients. Significantly high grain yield and protein yield was observed due to application 30 kg K and 20 kg S per hectare. Therefore balanced fertilization of NPKS nutrients is required in pigeon pea.
