Comportamiento morfológico del Maíz inoculado con Azotobacter chroococcum a dosis reducida de fertilizante nitrogenado Yanara Regla Huete Arrieta Jesús Torres Domínguez Duniesky Dominguez Palacio Multidisciplinarias (Ciencias, Ciencias Sociales, Artes y Humanidades) Biofertilizantes bacterias promotoras del crecimiento vegetal sustancias promotoras del crecimiento vegetal La inoculación con bacterias promotoras del crecimiento vegetal del género Azotobacter, es una alternativa para la reducción y optimización de los fertilizantes nitrogenados. El objetivo de este trabajo fue evaluar la respuesta del maíz (Zea mays) a la inoculación con Azotobacter chroococcum empleando diferentes dosis y aplicando el 50 % del fertilizante nitrogenado, así como una combinación de A. chroococcum y vermicompost. El trabajo se realizó bajo un diseño experimental en bloques al azar con cuatro tratamientos y cuatro replicas. La respuesta del cultivo a los tratamientos se evaluó en caracteres morfológicos expresados en por ciento de germinación de la semilla, altura de la planta, peso fresco aéreo, peso fresco radical, peso seco aéreo y peso seco radical. Los resultados probaron la respuesta positiva del cultivo del maíz a la inoculación con A. chroococcum y de A. chroococcumcon vermicompost en todas las variables estudiadas. El mejor resultado se obtuvo con la aplicación combinada de A. chroococcum y vermicompost a dosis de 15 lha -1 y 2 t ha-1 respectivamente, expresados en un por ciento de germinación de la semilla de 98,4 %, una altura de la planta de 1,14 m; un peso fresco aéreo de 40,7 g; un peso fresco radical de 20,4 g; un peso seco aéreo de 10,1 g y un peso seco radical de 5,1 g. 2019 artículo científico 1562-3297 https://www.redalyc.org/articulo.oa?id=637869113003 https://www.redalyc.org/journal/6378/637869113003/ https://www.redalyc.org/journal/6378/637869113003/html/ https://www.redalyc.org/journal/6378/637869113003/637869113003.epub https://www.redalyc.org/journal/6378/637869113003/movil es http://www.redalyc.org/revista.oa?id=6378 Avances application/pdf Instituto de Información Científica y Tecnológica Avances (Cuba) Num.2 Vol.21
