Abstract
A field study has been conducted during autumn season of 2016 at Karbala province of Hindia by mungbean crop Vigna radiate L. to study the interrelated effect of both the Mycorrhizal fungi (Glomus mosseae ( and the Rhizobial bacteria ( R.leguminosaru (Under levels of water stress. Three treatments of irrigation are used ; (S1 irrigation every 5 days and S2 irrigation every 10 days and S3 irrigation every 15 days) and four levels of Bio fertilizer are used (without inoculation)(C0) and (Rhizobium inoculation)(R) and (mycorrhizal inoculation)(M) and (the interaction between mycorrhizal and Rhizobium)(M+R). A split plot in randomized complete block design is used with three replications. Treatments of irrigation are used as main plots while Bio fertilizer levels are used as sub-plot. Least significant difference (LSD) at 5% probability is used to compare the means. The results showed irrigation every 5 days (S1) was superior in having the highest average of (plant height, leaf area, relative water content of leaves, root length, dry weight of roots, and infection Mycorrhizal inoculum)Amount (50.63 cm. Plant-1, 576.4 cm2. Plant-1, 74.68 %,17.79 cm. Plant -1 , 0.78 gm. Plant-1, 58.9%) respectively. While Biofertilization treatment (mycorrhizal and Rhizobium)(M+R) showed its superiority in all characteristics. The interaction among (R+M)S1,(R+M)S2 and (M)S1 significantly give the highest means for all plant characteristics.
