Abstract: A field experiment was conducted during rabi season, 2012-13 at Nursery, Rajaula Agriculture Farm, Mahatma Gandhi Chitrakoot Gramodaya Vishwa Vidhyalaya, Chitrakoot, Satna (M.P.). In this investigation, the treatments consisting of four levels of sulphur (0, 20, 40 and 60 kg/ha) and four levels of potash (0, 40, 80 and 120 kg/ha) were tested in factorial randomized block design with three replications to study the interaction effect of sulphur and potash on growth, bulb yield and nutritional values of onion. The study revealed that crop fertilized with sulphur (60 kg/ha) coupled with potash (80 kg/ha) had brought significant effect in the interaction effect of both level to recorded maximum mean horizontal diameter of onion bulb, mean vertical diameter of onion bulb, mean dry weight of onion bulb and yield were recorded in sulphur application (60 kg/ha). Similar trends were also noted in phosphorous, potassium and sulphur in bulb. Thus, onion fertilized with (60 kg/ha) in combination with potash @ 80 kg/ha proved to be most affected to recorded growth, bulb yield and nutritional values of onion.
