Abstract: Field experiments were carried out to study the response of onion to different levels of sulphur (0, 15, 30kg/ha), zinc (0, 2, 4 kg/ha) and boron (0, 1, 2 kg/ha) along with recommended dose of fertilizer. totally 27 treatment combinations were made, laid out in factorial randomized block design with two replications, conducted at Olericulture unit of Kittur Rani Channamma College of horticulture, Belgaum district (Karnataka), during kharif, 2016. Results revealed that application of sulphur (30 kg/ha) significantly increased the polar diameter (6.05cm), equatorial diameter(6.33cm), bulb yield (31.25t/ha), fresh weight of bulb(107.07gm), dry weight of bulb (33.50gm),Total soluble solids (13.08 0B), sulphur content in bulbs (0.59%),when applied with zinc (4kg/ha) and boron (2kg/ha). The study indicated that application of sulphur (30 kg/ha), zinc (4kg/ha) and boron (2kg/ha) with recommended dose of fertilizers was found to be the most appropriate combination for getting higher yield compared to other treatments.
