A field experiment was conducted for the agricultural season (2019-2020) in Abu Gharq area to study the effect of different levels of manganese spraying (manganese sulfate) and different levels of phosphate fertilizer in some growth and yield of Phaseolus vulgaris L., the local cultivar, in a factorial experiment with a complete randomized block design RCBD, with three replications .The first factor included spraying 3 concentrations of manganese (0, 20, 40 mg.L-1) and the second factor with 3 levels of phosphate fertilization (0, 50, 100 kg phosphorous.ha-1) and their interaction, The results indicated a significant superiority of spraying with the element manganese at a concentration of 40 mg.L-1, and it gave the highest significant mean in the traits of plant height, leaf area, dry weight, percentage of nitrogen and phosphorous in leaves, number of pods per plant, number of seeds per pod, the weight of 100 seeds, total yield, protein and carbohydrates percentage in seeds, While the treatment of adding phosphorous at a concentration of 100 kg.phosphorous.ha-1 gave the highest significant average for the above traits.
