It was arranged in Randomized Block Design with 3 treatments and 5 replications. Yield attributes for all treatments are significant except neck thickness and neck diameter. Maximum Yield (295q/ha), bulb size (5.56cm), neck thickness (5.8cm) Plant height (51.6cm), Number of leaves (8.3) and length of leaf (39.9cm) were recorded from the doze of 30 kg Sulphur per hectare.
