The effect of micronutrients and time of spraying on the yield and yield components of faba ‎bean (Vicia faba) in Kohgiluyeh-va- Boyerahmad, Iran‎

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, ‎
