The Role of Bio Fertilizer in Reduction of Irrigation Periodsfor the Yield and Components of Mung Bean
Abstract
A field study has been conducted during autumn season of 2016 at Karbala province of Hindiaby mung bean plant Vigna radiate L. is a local category to study the interrelated effect of both the Mycorrhiza fungi (Glomusmosseae(and the Rhizobia bacteria (R.leguminosarum)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 (mycorrhiza inoculation)(M) and (the interaction between mycorrhiza and Rhizobium) (M+R). A split plot in randomized complete block design is used with three replications to do this experiment. 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 between the means. The results showed irrigation every 5 days (S1) was superior in having the highest average of (The dry weight of the root, number of pod per plant, number of seeds per pod ,100 seeds weight ,seed yield ,Biological yield) Amount(0.78 gm.

Moreover treatment Bio fertilizer (R+M) significantly gives the highest means for yield and yield components (0.89 gm. Plant-1, 33.64pods.
