To study the effects of micronutrients (iron,zinc and boron) on the quantitative (yield) and qualitative (percent of protein and oil) properties of soybean, an experiment was carried out in 1997-98 in Aleshtar plain( lorestan province). Fourteen different micronutrient treatments with three replications were applied in a completely randomized block desingn. Treatments (as chemical fertilizers) were applied in Three methods: soil application, Foliar application, soil and Foliar application together. In all of the treatments except check, saybean seeds were inoculated with bacteria (rhysobium) and molybdenum (ammonium heptamolyb date). In check treatment, micronutrients, bacteria and molybdenum were not applied. Statistical amalysis of results showed that effects of treatment on yield, protein and oil percent of soybean is not meaningful. The results of the experiment can be reasonable according to the soil test. Data of soil test revealed that the quautities of iron , zinc and boron in the soil was more than their critical levels for soybean. So the effect of these elements (in any application method) on soybean was not meaningful statistically.
