Elements such as nitrogen (N), molybdenum (Mo), and cobalt (Co) are needed to improve the quantity and quality of beans. In order to study the effects of these substances on pod yield as well as nutrient concentration of this plant, a factorial pot experiment was conducted in 2016 under greenhouse conditions at University of Zanjan, using a CRD with three replications. The experimental factors included four levels of N (50, 100, 150, and 200 mg/l), three levels of Mo (0. 067, 0. 2, and 0. 6 mg/l), and Co (0. 006, 0. 06, and 0. 3 mg/l). Results have shown that the highest dry weight of pods belongs to treatment of N100Mo0. 2Co0. 06, equal to 34. 05 g/pot, without any significant difference from N150Mo0. 6Co0. 06 treatment. The application of different levels of factors raises the concentrations of N, P, and Mg in bean leaves in N200Mo0. 6Co0. 3, N200Mo0. 6Co0. 006, and N150Mo0. 6Co0. 3 treatments. The highest concentration increase in the mentioned elements have been 6. 94%, 0. 91%, and 0. 41%, respectively. However, the concentrations of K and Ca decrease as a result of the application of the factors. The highest concentrations of Fe, Mn, Cu, Mo, and Co bean have been in treatments of N200Mo0. 6Co0. 006, N150Mo0. 2Co0. 006, N200Mo0. 6Co0. 3, N150Mo0. 6Co0. 3, and N150Mo0. 067Co0. 006, being 490, 185. 4, 8. 26, 284. 5, and 54. 9 mg/kg, respectively. Overall, according to the results, N100Mo0. 2Co0. 06 is the recommended treatment for bean.
