In order to investigate the effect of foliar application of Iron, Zinc and Boron micronutrient elements on two different irrigation regimes on soybean characteristics of M9 cultivar, a RCB design was conducted with 8 treatments in 3 replications. The experiments were done in Aleshtar, Lorestan province of Iran during two growing years between 2014 to 2016 in two separate experiments. The first irrigation was carried out after 50 mm from the pan and in the second experiment after irrigation after 100 mm from the pan. The investigated factor were micronutrient elements including micronutrient spraying, micronutrient spraying of Zinc, Iron, Boron, Zinc& Iron, Boron + Iron, Boron + Zinc and Zinc + Iron + Boron. The results showed that irrigation effect on plant height, number of nodes, number of pods per plant, 1000 seed weight, oil yield and grain yield were significant at 1% probability level. The effect of foliar application of micronutrient elements on plant height, number of nodes, number of pods per plant, number of seeds per pod, 1000 seed weight and grain yield at 1% probability level and significant number of lateral branches at 5% probability level were significant. The highest grain yield was obtained from irrigation treatments after 50 millimeters from the pan and the addition of Zinc, Iron and Boron micronutrients, with a mean of 2561 kg ha-1, and the lowest grain yield related to treatment after 100 mm of pan and lack of foliar application of micronutrient elements with an average of 1086 kg ha-1.
