Stenotrophomonas sp. LIMN, Enterobacter sp. LCMG, and Rhizobium sp. WFRFC: A Bacterial Consortium in the Production of Zea mays L. Under Different Agronomic Management Practices.

Abstract

Objective: To evaluate the effect of the bacterial consortium Enterobacter sp. LCMG, Rhizobium sp. WFRFC, and Stenotrophomonas sp. LIMN on three different agronomic management practices in maize (Zea mays L.) cultivation, with the question: Does the consortium of bacterial strains have a positive influence on maize production under different cultivation practices in the Ciénega region, Jalisco? Design/methodology/approach: Treatments evaluated were TM= 100 % traditional management + bacterial consortium (BC), TM+AM= 50 % traditional management + 50 % agroecological management + BC, and AM= 100 % agroecological management + BC. A randomized complete block design was established, and agronomic and yield variables were evaluated. Results: The MT+MA treatment generated a 6.03 % increase in grain yield; generated a 10.35 % increase in ear height, a 4.87 % decrease in plant height, and a 50 % decrease in the consumption of synthetic products. Limitations on study/implications: The agronomic management was carried out according to the practices of the region's farmers. Findings/conclusions: The bacterial consortium Enterobacter sp. LCMG, Rhizobium sp. WFRFC, and Stenotrophomonas sp. LIMN had a positive effect on maize cultivation for grain production, particularly when combined with agronomic management consisting of 50 % traditional management + 50 % agroecological management. The bacterial consortium could be used as a bio-stimulant in maize production in the Ciénega region, Jalisco.
