Plant nutrition is one of the most important environmental factors affecting the yield and yield components of crops such as soybean. This study was conducted to of nitrogen-fixing bacteria, humic acid and foliar application of micronutrients on yield and morpho-phenological traits of soybean (Saman cv.) in a factorial randomized complete block design with three replications at Gorgan agricultural research station in two cropping seasons (2019-2020). Experimental factors include foliar application of humic acid at two levels including fulvic and humic acid; Bacterial seed at three levels including bacterial seed, bacterial seed + Azospirillium and control; And nutrient spraying was applied at four levels including cobalt, cobalt + molybdenum, cobalt + molybdenum + boron and control. Based on the results, the effect of simple effects was significant on the studied traits. The bacterial (Rhizobium) + Azospirillum and cobalt + molybdenum + boron significantly increased the traits than control. Grain yield under the humic acid (2750 kg/ha), bacterial seed + Azospirillum (2238 kg/ha) and cobalt + molybdenum + boron (2388 kg/ha) showed higher values compared to other treatments.In general, the results of this study indicate the efficiency of nitrogen-fixing bacteria as well as foliar application of micronutrients in increasing soybean yield.
