Field experiments were carried out in the fields of the Faculty of Agriculture, Tikrit University during the 2018 season, which included dry plant parts (total root and vegetative total) with 50% and 100% concentrations of the whole plant at a concentration of 50% and 100% for Sonchusoleracens to study the adverse effect of mention treatments on bacterial contract number weight Nitrogen and phosphorus concentration in leaves, phosphorus and protein ratio in the nutritional value of Glycin max L.. The results of the experiment showed a significant reduction in the number and weight of the bacterial contract of the soybean plant in the soil added to it. The vegetative residue of the milk plant at 50% and 100% concentration. The contract disappeared at 100% for vegetative and root crops, Radical) concentrations of 50% and 100%. As for the concentration of nitrogen and phosphorus in the leaves did not show significant differences for all the treatments, while there were significant differences in the percentage of phosphorus in the seeds, where the treatment gave a total vegetative concentration of 100% less average value (1.29%) compared to the comparison treatment without adding, (1.62)%. The mean values ​​showed significant differences in the percentage of protein in soybean seeds. If the vegetative treatment was treated, the mean was less (15.58%) compared to the comparison treatment without adding, which gave an average of (27.34) %.
