The overuse of nitrogen and phosphate fertilizers in crop production has led to the need to search for alternatives such as plant growth promoting bacteria, which can enhance productivity and improve the quality of corn crops, thus contributing to the health of the consumer, the soil, water and the environment. The objective of this work was to evaluate the plant growth promoting characteristics of bacteria isolated from maize (Zea mays L.)". Nine bacteria (B1, B2, B3, B4, B5, P1, P2, P3, P4) were isolated from the province of Picota, districts of Barranquita and Tingo de Ponaza. The bacteria were isolated using two nitrogen-free culture media, MJV and Burk. Only 1 strain was unable to produce indole acetic acid under the established conditions, the remaining strains (8 strains) produced IAA in a highly variable range (from 1.08 to 11.12 µg IAA/ml TSB). The 100% of the strains isolated from the corn crop solubilized phosphates and produced siderophores with an efficiency greater than 30 μg/ml, with strains B1 (Barranquita) and P4 (Tingo de Ponaza) showing the highest production of 171.35 and 151.89 μg/ml, respectively. The methodologies of the present research constitute "one of the most used strategies to select microorganisms with biotechnological interests". These can allow "developing alternative products to chemical synthesis fertilizers and pesticides", thus favoring an increase in corn crop productivity.
