Abstract

A field experiment was conducted during 1992 94 to study the response of onion (Allium cepa L.) to doses, sources and methods of potassium application. The bulb yield increased significantly up to 120 kg K20/ha. Sulphate of potash (SOP) resulted in higher bulb yield than muriate of potash (MOP). The bulb yield significantly increased with split application of K 2 0 , being the highest with 3 splits. Uptake of N and K increased with increasing levels of S O up to 120 kglha. Application of SOP increased the utilization of N, Ca and M g compared with MOP. Split application of K increased the utilization of N, K , Ca and Mg compared with its basal application. Uptake of N increased up to 3 splits of K. Increasing levels of K,O up to 120 kglha increased the carbohydrate content in bulb. The pungency also increased by application of K. Bulbs receiving SOP were more pungent than bulbs receiving MOP.
