Influence of micronutrient fertilizer on soybean nutrient composition

In order to study the effects of micronutrient fertilizers on nutrient composition of soybean, two set of experiments (pot and field) were done at the Islamic Azad University of Kermanshah province, Iran in 2010. The experimental design was a 333 factorial experiment based on Randomized Complete Block with three replicates. In the pot experiment, treatments included Zinc (0, 4, and 8 mg Zn kg-1 as ZnSo4.7H2o), iron (0, 4, and 8 mg Fe kg-1 as FeSo4), and manganese (0, 15, and 30 mg Mn kg-1 as MnSo4.4H2o). Treatments in field experiment consisted Zn (0, 20 and 40 kg Zn ha-1), Fe (0, 25 and 50 kg Fe ha-1) and Mn (0, 20 and 40 kg Zn ha-1) from source of ZnSo4, FeSo4 and MnSo4 , respectively. The results were shown that Zinc application had significant effects on Zn, Fe concentration in roots (P
