evaluation of sulfur fertilizer on canola yield under salinity conditions

soil and water salinity damage and decrease canola yield. however, plant yield should be increased using effective methods. this study aimed at investigating the effect of sulfure application fertilizers on canola yield. to this end, the experiment was conducted in split plot arrangement based on randomized complete blocks design with three replications at shavoor research station in south west of iran. main plots was the source of sulfur fertilizer (sulfur element, gypsum, sulfuric acid, golden bio-sulfur) and sub plots were the rate of sulfur application including 6 levels (0, 50, 500, 1000, 1500, 2000 kg s.ha-1). results showed sources and rate that of sulfur fertilizers had significant different effects (p
