Abstract
In order to study the effect of micronutrients and time of spraying on the yield and yield components faba bean (Vicia faba), a Factorial Test was performed on twelve treatments in the form of a simple sampling and in three replications. Micronutrients in four levels (experimental iron, zinc, of Iron and zinc) was considered as the first factor and time of spraying in three levels flowering, 50% flowering and full flowering) was considered as the second factor. After the was prepared in November 2013, seeds were planted in rows of 50cm in pre-determined plots. complete ripening of the bushes, the related traits were measured and recorded. The study traits ed seed yield, plant biomass, plant height, number of side branches, one hundred-seed weight number of seeds per pod. According to the results obtained from the comparison of the means of data, the interaction of factors of micronutrients and time of spraying had a significant effect on the of seed yield, plant biomass, one hundred-seed weight and number of side branches of faba bean they had no significant effect on the number of seed per pod and number of side branches. The um seed yield (550g per square meter) and maximum biomass (1100mg per square meter) was in the treatment of interaction of iron and zinc in flowering time. Based on the results in the present study, simultaneous use of micronutrients of iron and zinc in the stage of full is recommended for increasing seed yield in climatic conditions similar to that of Dehdasht,
