Abstract :

To investigate the effect of non-iron chelates application on yield of sesame Darab 14, an experiment was conducted as randomized complete block design with three replications in 2012 at Meybod University. Nano-iron chelates in quantity of 10 and 20 Kg/ha as soil and foliar spray with the density of 1/1000 were studied in the phases of stem elongation, flowering, stem elongation with flowering and the control group (without fertilization). The characteristics of plant height, numbers of capsules per plant, number of seeds in each capsule, weight of thousand seeds, yield of seed, biologic percentage of oil, amount of iron in seed were evaluated The results show that spraying dunging flowering with stem elongation and stem elongation has the most effect on the characteristics of plant height, number of seeds per capsule, number of capsules per plant and biologic procedure .Weight of 1000 seeds was significant only in soil consumption of 20 Kg of nano-iron chelates. The amount of iron in seed increased in all phases except spraying consumption in stem elongation. The findings showed that spraying in stem elongation with flowering and stem elongation and soil commotion of 10 and 20 Kg/Hec of nano-iron increased quantitative yield in sesame.
