ABSTRACT: 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 -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*) .
