Abstract
The present investigation entitled “Effect of potassium and sulphur on yield and nutrient uptake of pigeonpea” was conducted on EAD Farm, College of Agriculture, Nagpur during kharif season of 2017-2018. The field experiment was laid out in Factorial Randomized Block Design (FRBD) with four levels of potassium (0, 15, 30 and 45 kg ha-1) and four levels of sulphur (0, 10, 20 and 30 kg ha-1). Results indicated that grain and straw yield; content and uptake of N, P, K and S increased with increased in rate of application of K and S. The result of present experiment indicate that application of 30 kg K2O ha-1 resulted improvement in grain (11.59 q ha-1) and straw (45.14 q ha-1) yield of pigeonpea. The highest uptake of N (110 kg ha-1), P (21.35 kg ha-1), K (90.15 kg ha-1) and S (12.50 kg ha-1) was recorded with the application of 20 kg sulphur ha-1. The uptake of N and K increased due to application of 30 kg K2O and P and S due to 45 kg K2O ha-1.
