Single And Co-Inoculation Of Native Arbuscular Mycorrhizal Fungi (Amf) And A Plant Growth Promoting Bacillus Subtilus (Alcr46), On The Growth Of Three Vegetable Species In A Low Phosphorus Soil

Abstract

Arbuscular Mycorrhizal Fungi (Amf) And Plant Growth Promoting Rhizobacteria (Pgpr) Are The Major Component Of The Soil Microbial Populations, Which Play Significance Roles In Improving Soil Fertility, Plant Growth And Health; Hence, This Study Was Aimed To Investigate The Effect Of Single And Co-Inoculation Of Amf And A Pgpr, Bacillus Subtilus (Alcr46) On Three Selected Vegetables, Lycopersicum Esculentum (Tomato); Allium Cepa (Onion) And Cucurbita Pepo (Squash). The Experimental Design Was A Randomized Complete Block Design With Three Replications In A Greenhouse. Seven Treatments Were Set Up As Follows: Plants Without Inoculation (Negative And Positive Controls), With The Consortium And Single Amf Inoculation, With Bacillus Subtilus Inoculation, And With Co-Inoculation Of Pgpr And A Single And Consortium Of Amf. In This Work, The Growth Parameters Like Root Length And Shoot Height, Fresh And Dry Weight Of Root And Shoot, And The Number Of Branches; Percentage Of Root Colonization, Spore Number Were Measured And All Data Were Analyzed By Anova. The Result Shows That The Growth Of The Vegetables Significantly Increased By Co Inoculation Of The Consortium Species Of Amf And Bacillus Subtilus (Alcr46). Amf Spore Density And Colonization Rate Were Also Increased In Co-Inoculation. Moreover, Results Indicated That The Highest Root Colonization, Spore Number, And Mycorrhizal Dependency Were Observed In Allium Cepa Among The Selected Vegetables. Furthermore, Pearson?��?Scorrelation Analysis Showed
