Response of onion to foliar spray with seaweed extract and GA at different irrigation levels


Abstract in English

Yhis study was investigated at Agriculture Faculty of Damascus university during the agricultural season of 2012/2013 in order to determine the effect of foliar spray with seaweed extract (5 and 10 g/l) and GA3 (50 and 100 ppm) on the growth and production of local red onion (Baladi) at different levels of irrigation (100, 75, and 50% of field capacity). Onion bulblets were planted in pots and plants were treated when they had 3-4 leaves and every two weeks until full vegetative growth.
