| In order to investigate the effects of different amounts of iron and sulfur fertilizers on some quantitative characters of sesame under drought stress conditions, an experiment was carried out as a split factorial design in randomized complete blocks with three replications during summer 2010 at city of Gotvand. Treatments consisted of drought stress as main factor at two levels (control and stress in flowering stage) and fertilizer treatment as sub-factor consisted of: iron in three levels (0 (control), 3 and 6 per 1000 from iron solution) and sulfur at three levels (0 , 200 and 500 kg/ha from bentonite sulphurin). The results of this experiment showed that drought stress in flowering stage had no significant effect on grain yield but among the grain yield components, drought had significant effect on pod number per bush and sub branch number and decreased them. Iron and sulfur had not meaningful effect on grain yield and yield components separately. In this experiment the highest grain yield was obtained during using iron and sulfur fertilizers in 200 kg sulfur fertilizer treatment and 3 per 1000 iron spraying. |
