Effect of microbial consortium application on wheat cultivated in catamarca, Argentina

The objective of this study was to determine the effect of applying a microbial consortium on wheat cultivation in the province of Catamarca, Argentina. An inoculant composed of strains of the biocontrol fungus of the genus Trichoderma spp., bacterial strains of Azospirillum brasilense, Bacillus thurigiensis, Rhizobium leguminosarum, and Bradyrhizobium sp. was used. A randomized block design was used with two treatments and three replications: one treatment with microbial consortium inoculation and another control treatment. Two applications were made at 5 and 43 days after sowing. The study evaluated wheat yield variables (total grain production, weight of 1000 grains, number of grains per spike, number of spikes per unit area, and harvest index) and growth and development variables of wheat plants (root weight and aerial biomass weight). The results indicate that the application of the microbial consortium significantly increased yields, growth, and development of wheat plants compared to the control treatment. It was determined that applications of selected native microorganisms have a plant growth-promoting effect, increasing the growth and productivity of wheat crops.
