Effect of Levels and Sources of Potassium on Yield and Nutrient Uptake by Chilli (Capsicum annuum L.) in a Vertisol

In a field experiment conducted on Typic Chromustert at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, the yield of chilli was significantly influenced by the levels and sources of potassium. The treatment that received 150 per cent RDK through SOP in 2 split doses recorded highest fruit yield (10.71 q ha^-1). The highest uptake of N (67.93 kg ha^-1), K (106.77 kg ha^-1) and S (15.30 kg ha^-1) were noticed with the application of potassium at the rate of 150 per cent RDK through sulphate of potash in 2 split doses.
