A field experiment was conducted during Kharif 2006 on a vertisol to study the effect of potassium and sulphur on yield and yield parameters of onion and chilli intercrops grown 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). Yield and yield attributes of onion and chilli increased with the individual application of 100 kg K2O ha-1 and 30 kg S ha-1. The combined application of 100 K>sub>2O and 30 kg S ha-1 recorded the maximum yield of both onion (19.52 t ha-1) and chilli (3.90 q ha-1) and also onion equivalent yield (23.42 t ha-1) of the intercropping system.

Abstract


A field experiment was conducted during Kharif 2006 on a vertisol to study the effect of potassium and sulphur on yield and yield parameters of onion and chilli intercrops grown 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). Yield and yield attributes of onion and chilli increased with the individual application of 100 kg K2O ha-1 and 30 kg S ha-1. The combined application of 100 K>sub>2O and 30 kg S ha-1 recorded the maximum yield of both onion (19.52 t ha-1) and chilli (3.90 q ha-1) and also onion equivalent yield (23.42 t ha-1) of the intercropping system.
