ABSTRACT
The present investigation was carried out during 2015-16 at Agricultural Research Institute, PJTSAU, Rajendranagar, Hyderabad, Telangana State, India. 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 bulb yield, selenium content and antioxidant properties. 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. The selenium content in onion bulb ranged from 5.10 to 15.84 mg kg-1. The antioxidant properties such as phenols and flavonoids significantly increased with the increased levels of soil applied sulphur and foliar sprayed selenium in onion crop.
Key words :
Bulb onion, DPPH radical scavenging activity, Sulphur, Selenium content, Total flavonoid content, Total Phenol content, Yield attributes.
