 ABSTRACT

The present investigation was carried out during 2015-16 at Agricultural Research Institute, PJTSAU, Rajendranagar. Four levels of soil applied sulphur (0, 15, 30 and 45 kg S    ha-1) in combination with four levels of foliar sprayed selenium concentration (0, 25, 50 and 100 ppm) was tried on onion to know their effect on yield, sulphur and selenium contents and their uptakes. The onion crop responded to sulphur application in the range of 10 to 31 percent. Onion bulb yield increased with selenium application only up to 50 ppm spray and subsequently, the yield decreased. Sulphur content in onion bulbs ranged from 0.35 to 0.52 percent due to increase in levels of sulphur application. The selenium content in onion bulb ranged from 5.10 to 15.84 mg kg-1. Antagonistic relationship of sulphur and selenium was observed due to highest sulphur dosage applied to soil (45 kg S ha-1) in combination with highest foliar concentrated spray (100 ppm).

Key words: Selenium, Sulphur, Onion, yield, Selenium content, Selenium uptake, Sulphur content and Sulphur uptake.
