چکیده مقاله :
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<0.01) on canola yield and biologic yield but they had no effect on grain thousand weight and grain in capsule. The highest grain yield and biologic yield obtained from Golden bio sulfur application. The findings also revealed that Interactive effects had significant effects (p<0.01) on canola yield and biologic yield but they had no effects on grain thou-sand weight and grain in capsule. Sulfur fertilizer application is an effective method for compensation damage yield of canola in salinity conditions.
