Abstract: 

In order to investigate the yield and components of safflower under plant residue treatments, nitrogen and micro element in Ahvaz, this experiment was conducted during 2010-2011 cropping season in Agriculture College of Shahid Chamran University of Ahvaz by using split plot based on Randomized Complete blocks design with three replications. Different values of plant residues at four levels (complete residues (5 ton/ha straw), incomplete plant residues (3 ton/ha straw), burning of plant residues and elimination of the plant residues) and sub-factor different values of nitrogen fertilizer at 3 levels (consumption of 150, 100 and 50 kg N/ha) and sub-sub-factor micro elements of spray at 2 levels (micro elements unsparing and spraying recommendeddose of fertilizer) was considered. Based on the results, a significant difference in grain yield, captiual per plant, grain per captiual, 1000 grain weight, and oil percentage was showed. Maximum grain yield resulted from treatment of incomplete plant residues, 100 kg N/ha and spray of micro elements (with mean 6278.87 kg/h). Minimum grain yield resulted from burning of plant residues, 50 kg/h and micro elements (with mean 1771.48 kg/h). The highest percentage of oil was equal to 33.5% (in complete plant residues with 150 kg N/ha and spraying micro elements) but that was not significant from 31% that was obtained in incomplete plant residues with 100 kg N/ha with spraying micro elements.
