MARTINEZ BLANCO, Berenice et al. Use of plant growth promoting bacteria to increase the production of Lactuca sativa L. in the field. Rev. Mex. Cienc. Agríc [online]. 2020, vol.11, n.2, pp.449-452.  Epub 15-Mar-2021. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v11i2.1944.

The extensive use of agrochemicals to increase food production today has led to loss of soil fertility, poor crop yield, loss of profits for farmers among many other negative factors, plant growth promoting bacteria they have used to increase the production of crops of agricultural interest, reducing the use of chemicals and creating sustainable agriculture. The objective of this work was to evaluate two consortia of bacteria characterized as BPCV, in lettuce crops. Lettuce orejona cultivation was carried out directly on a demonstration plot, throughout the process it was accompanied by the farmer, the seeds were previously disinfected, embedded by the consortiums used and germinated in pachol directly in the soil, then the seedlings they were placed in grooves to follow up. Obtaining larger lettuce and biomass with consortium B consisting of B. licheniformis, P. putida, Pseudomonas sp., E. cloacae and A. vinelandii with a value of p< 0.05. For what is proposed as a strategy to increase the production of Lactuca sativa L., in the communities dedicated to this crop, improving production yield, greater economic and environmentally sustainable gains.
