Lettuce and broccoli are valuable agricultural products in Ecuador whose cultivation demands considerable quantities of mineral nutrients, usually obtained from chemical fertilizers. As the use of plant growth-promoting rhizobacteria (PGPR) has shown to be a biological alternative for cropping these vegetable species, several strains of Bacillus spp. were evaluated through laboratory and field tests. Biological nitrogen fixation was performed by a qualitative assessment in a free nitrogen culture medium; the indoleacetic acid production was carried out in a Tryptic Soy Broth (TSB) medium by quantifying its concentration using Salkowski’s reagent; phosphate solubilization was established on an NBRIP medium and the transformed phosphorus conc...
