Abstract

In last decades, sever population growth cause to enormous problems in developing countries. One of the effective factors in improving of quantity and quality of agricultural products is optimal application of chemical fertilizers. Hence, any research in this field can be an effective step to decrease production costs and increase productivity. In order to evaluation effects of complete micro nutrient on soybean yield and yield component, an experiment was conducted in Islamic Azad University of Tabriz. Three level of complete micro nutrient (a1: 3 ppt or 10 kg ha-1, a2: 6 ppt or 20 kg ha-1 and a3: 9 ppt or 30 kg ha-1) and seven growth stages (b1: control, b2: soil application, b3: foliar application at 8-12 leaf stage, b4: foliar application at flowering stage, b5: foliar application at pod stage, b6: foliar application at pod and flowering stages and b7: foliar application at 8-12 leaf stage, pod and flowering stages) arranged in a RCBD based split plot design in three replication. Pod per plant, Pot weigh per plant, chlorophyll content, seed yield (p<0.05) and filled pod weight and kernel pods number (p<0.05) were affected by levels of complete micro nutrient. Application times was affected on stem height, seed number per pod, filled pod, pod weight, shilling percentage, yield (p<0.05) and pod per plant, 100 kernel weight, 3 kernel pods number (p<0.05). Interaction effect on filled pod weight, shilling percentage, 100 kernel weight, leaf area and yield was significant (p<0.05). The highest seed yield was obtained by using 3 ppt of complete micro nutrient at 8-12 leaf stages caused 88.88% increasing in seed yield compared to control. The highest 100 kernel weight was obtained by using 30 kg ha-1 of complete micro nutrient in soil application form as caused 14.90% increasing in seed yield compare to control. If intention is cultivation of Wiliam cultivar of soybean, 3 ppt of complete micro nutrient at 8-12 leaf stages are the most suitable fertilizer concentration and application stage for achieving higher seed yields, 100 kernel weight, filled pod weight and leaf area in comparison with other application concentrations and methods.
