A field experiment was conducted in a greenhouse north of Babylon City, during the Autumn season 2019-2020, to study the effect of two factors, the first nano-stimulator application, and the second-factor spraying micronutrients (Zn, B, Mo) on the growth and yield of common bean (Phaseolus vulgsris L). A factorial experiment was carried out using the split plots system within a randomized complete block design (RCBD), where the micronutrients (Control, Zn, B, Mo, Zn+B, Zn+Mo, B+Mo, Zn+B+Mo) were distributed in the main plots, while the nano- stimulator (sprayed with concentration 0.75 ml L -1 water) was distributed on the sub-plots. The results showed that spraying the nano-stimulator positively affected the chlorophyll, the percentage of dry matter in the leaves, the zinc content of the leaves, and the activity of the Catalase enzyme. Micronutrients were also significantly affected in all the studied indicators.
