A pot experiment was conducted to study the effect of mycorrhiza, fungicides in difference concentration and there combination on growth and nutrients balance index of soya bean. Tow AM treatments including with and with out mycorrhiza and tow fungicides parasmid and ant-arcol each of them including four concentration 0.0, 0.25, 0.5 and 1 Kg·donum-1 were tested in factorial completely randomized design in the three replication. The results indicates that the higher value of total dry matter weight was recorded from combination treatment F1M1C1 which attained 11.09 gm·pot-1 ,while the lower value 2.25 gm·pot-1 was produced by combination treatment F2M2C3 ,however the same combination treatments was showed that the nitrogen ,phosphorus ,magnesium and iron in the shoot tissues in the mycorrhizal plant with lower concentration of fungicides were significantly greater P < 0.01 compared to control and higher concentration treatments. The higher concentration of the above mentioned nutrients 28.33, 8.36, 6.34 mg·g-1, 251.00 mg·K-1 was recorded. The result of nutrient index and nutrient balance index revealed that the lower NBI 56.18 was recorded in combination treatments F1M1C1, while the higher NBI 2033.81 was produced from combination treatments F2M2C3, moreover the results shows significant negative correlation ship between NBI and total dry matter weight r = -0.63* .
