 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 sunflower to know their effect on yield and their contents. The sunflower crop showed > 25% response to sulphur application. Sunflower seed yield increased with selenium application only up to 50 ppm spray and subsequently, the yield decreased. Sulphur content in sunflower seeds ranged from 0.15 to 0.33% due to increase in levels of sulphur application. The selenium content in sunflower seed ranged from 9.12 to 20.12 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, Sunflower, yield, Selenium content, Selenium uptake, Sulphur content and Sulphur uptake.
