Investigation the effect Boron Failiar application on quality and quantitative characteristics of Soybean Genotypes

Maintaining soil fertility and use of plant nutrients in sufficient and balanced amounts is one of the key components in increasing crop yields. In order to evaluation with effect of Boron foliar application on planting and morphological traits of soybean genotypes , a 4-replication in split-plot RCBD experiment was conducted under khoramabad research region of Islamic Azad University, in 2009. Foliar application in treatments in three control levels: no foliar application, foliar application two per thousand of Boron fertilizer at 50% flowering and poding , foliar application four per thousand of Boron fertilizer at 50% flowering and poding ,as sub plot and soybean genotypes consisting of M9, M7 and L17 were considered as main-plots.The results showed, foliar application of Boron, increases both seed yield and biological yield, oil and protein percentage significantly Also among the under studied genotypes ,M7 genotype proved higher grain yield(799/7Kg per hec), the reason for the superiority is the production of the highest biological yield and number pod per plant . About the protein trait Soybean seed exposed to foliar application of Micro nutrients Boron. Based on the obtained results of variance analysis and comparing the average data, a significant difference in 5% level was observed between 2 in 1000 and 4 in thousand Boron .M7 and M9 cultivar, in comparison to L17 cultivar had more protein.2 per thousand concentration of Bron had more share to increase Soybean seed oil in comparison with other treatments.
