Screening of Microorganisms with High Biological Activity to Create Consortia as A Growth Stimulator for Wheat Seeds

Abstract

Addressing the pressing need for more sustainable farming practices that concurrently enhance crop productivity, this study focuses on the identification of beneficial microorganisms and their impact on wheat seed germination. Through rigorous screening of microorganisms hailing from the wheat rhizosphere, a targeted approach was adopted to formulate microbial consortia, aiming for an additive effect in boosting plant growth. In the initial stage, a comprehensive screening was conducted on microorganisms isolated from the wheat rhizosphere soil. Subsequently, the influence of the culture liquids from these isolates, along with those of selected microorganism strains from established collections, on the growth rates of wheat was meticulously examined. These methodical investigations were instrumental in the formation of the microbial consortia. From an extensive pool of 35 collection strains and 16 isolates, microorganisms demonstrating the most significant positive impact on wheat growth were selectively chosen. Three potent consortia were subsequently formulated from these beneficial microorganisms. Although these findings are yet to be validated through practical application, the results offer promising prospects for their utilization in the agricultural sector. The identified microbial consortia present a green alternative to conventional fertilisers, thereby potentially contributing to the advancement of sustainable agriculture practices.
