Effect of Foliar Application of Micronutrients on Quantitative and Qualitative Characteristics of Soybean (Glycine max L.)

To investigate the impact of important micronutrients including iron, manganese and Biomax (complete fertilizer) on growth characteristics, performance and proteins of soybean (Williams cultivar), a study randomized complete block design with three replications and five treatments (control, iron, manganese, iron/Mn and Biomax) were conducted at the Agricultural Research Station, College of Agriculture and Natural Resources, Razi University. In this research, the amount of fertilizers was based on soil tests and was applied before and after flowering. The results of this research showed that in soybean plants, for the use of micronutrient elements, there is a significant difference in traits, plant height, the distance between the crown and the first sub-stem, stem diameter, the number of pods in the sub-branches, the number of pods per stem, the number of pods per plant, protein mg/pr and yield. There was no significant difference in pod length and number of seeds in pod traits. The comparison table showed that for most traits of all micronutrients, Biomax fertilizer had the greatest effect.
