Title A name given to the resource Evaluación de rizobacterias promotoras del crecimiento bajo diferentes esquemas de fertilización en el cultivo de maíz variedad HIMECA-95 Creator An entity primarily responsible for making the resource Alexis Valerio Valery Ramirez, Isbelia Reyes Description An account of the resource Evaluation of growth promoting rhizobacteria under different fertilization schemes in maize variety HIMECA-95 Titulo corto: Biofertilización del maíz Resumen: Bacterias previamente aisladas, y caracterizadas como diazotróficas y disolventes de  fosfatos inorgánicos se evaluaron en campo como promotoras del crecimiento vegetal en la producción de maíz variando las condiciones de fertilidad del suelo. Las cepas MF1b y MF5, en forma individual y en consorcio, se inocularon en semillas de maíz (HIMECA-95), y se sembraron bajo las siguientes condiciones de fertilización química: K, NK, PK, RK, NPK, y NRK (R: roca fosfórica). Al final del ensayo se determinó el peso seco total, y los contenidos de N y de P presentes en el grano para luego calcular el porcentaje de eficiencia agronómica relativa (%EAR). Los resultados obtenidos mostraron que la inoculación con la cepa MF5 en forma individual y en consorcio, con una fertilización quimica de NK, incrementaron la EAR del peso seco del grano en 130 y 403%, el contenido de N en 463  y 116%,  y el de P en 152 y 376%, respectivamente, logrando un aumento en la producción del grano de maíz y su calidad. Asimismo, se observó una variabilidad en las respuestas de los parámetros evaluados, lo cual podría deberse a los bajos contenidos de N y P del suelo, a los cambios en la fertilidad del suelo por la adición de los fertilizantes de alta solubilidad, y a la interacción entre las comunidades microbianas autóctonas y las bacterias introducidas. Se concluye que la efectividad de los microorganismos con potencial como biofertilizante para la agricultura sea evaluada cuidadosamente bajo diversas condiciones de fertilidad de los suelos.   Palabras clave: PGPR, fertilidad del suelo,bacterias diazotróficas, consorcio bacteriano, rendimiento   Abstract: Bacteria previously isolated, characterized as diazotrophic and inorganic phosphate solubilizers were evaluated under field conditions as plant growth promoters on the maize production when soil fertility was changed. The strains MF1b and MF5, alone and in consortium, were inoculated on maize seeds (HIMECA-95), and these were sown under the following chemical fertility conditions: K, NK, PN, RK, NPK, and NRK (R: phosphate rock). Total dry weight, and N and P contents of the grain were determined at the end of the experiment; also, the % of relative agronomic efficiency (RAE) was calculated. Results showed that inoculation with the strain MF5 alone and in consortium, with the addition of NK fertilizer increased the % RAE in 130 and 403 for the dry weight, in 463 and 116 for the N content, and in 152 and 376 for the P content, respectively, allowing an increase in both production and grain quality. Moreover, it was observed variations among the evaluated parameters which could be related to the low N and P status of the soil, the soil fertility changes after the addition of the highly soluble chemical fertilizers, and the interaction between autochthonous microbial communities and the introduced bacteria. It is concluded that the affectivity of a potential microbial biofertilizer for agriculture should be carefully evaluated under different fertility conditions of soils. Key words: PGPR, soil fertility, diazotrophic, bacteria consortium, yield.
