A field experiment was conducted during Kharif 2006 on black clay soil to study the effect of potassium and sulphur on onion and chilli intercrops in a vertisol with four levels of potassium (0, 50, 75 and 100 kg K2O ha-1) and three levels of sulphur (0, 15 and 30 kg S ha-1). The significantly higher uptake of N, P, K and S by onion plant as well as shoot and fruit portion of chilli were observed with the individual application of potassium @ 100 kg K2O ha-1 and sulphur @ 30 kg S ha-1.
