          Abstract

          Resumen Introducción. La situación del manejo inadecuado de los recursos en los sistemas productivos de maíz, estimula el desarrollo de nuevas estrategias orientadas al mejoramiento de la calidad, fertilidad y la salud del suelo junto a su entorno. Entre ellas, el uso de enmiendas para solventar las limitaciones presentadas en el crecimiento y desarrollo del cultivo como el problema de tipo antropogénico que afecta principalmente la calidad del suelo (alcalinidad, salinidad). Objetivo. Evaluar el efecto de 3 enmiendas sobre el crecimiento y desarrollo del cultivo de maíz con un plan de fertilización orgánico mineral. Materiales y métodos. El ensayo se estableció en la Finca El Danubio ubicada en Duaca al noroccidente de Venezuela con un diseño experimental de bloques completamente al azar con 6 tratamientos: T1: compost Don Manuel (CDM); T2: compost Minco Fértil (CMF); T3: Fosfoyeso (FY); T4: CDM+FY; T5: CMF+FY y control sin enmiendas. Las mismas fueron aplicadas manualmente en el surco de siembra, mientras que la fertilización orgánica con 16 productos y mineral (urea) fueron aplicadas a través del riego a partir de los 15 y 22 días después de la siembra. Resultados. Los resultados encontrados mostraron que el preparado de compost fórmula Minco fértil incrementó el crecimiento, altura de la planta, número de hojas y área foliar. Los mayores rendimientos de maíz para ensilaje y materia seca total fueron obtenidos con el preparado de compost Don Manuel y Minco fértil. No se encontró respuesta a la aplicación de las enmiendas orgánicas en las variables nutricionales de la planta. Conclusión. Se puede producir maíz forrajero con enmiendas orgánicas con efectos positivos en el crecimiento y producción del cultivo.

          Abstract Introduction. The situation of inadequate management of resources in corn production systems stimulates the development of new strategies that are aimed at improving the quality, fertility and health of the soil together with its environment. Including the use of amendments, to solve the limitations presented in the growth and development of the crop such as the anthropogenic type problem that mainly affects soil quality (alkalinity, salinity). Objective. To evaluate the effect of 3 soil amendments on the growth and development of the corn crop was evaluated using an organic mineral fertilization plan. Materials and methods. The trial was established at the Finca El Danubio located in Duaca in northwestern Venezuela with a completely randomized block design with 6 treatments: T1: Don Manuel compost (CDM); T2: Fertile Minco compost (CMF); T3: Phospho-Plaster (FY); T4: CDM + FY; T5: CMF + FY and control without amendments. They were applied manually in the seeding furrow, while organic fertilization with 16 products and mineral (urea) were applied through irrigation from 15 and 22 days after planting. Results. The results found show that the compost preparation formula fertile Minco increased the growth variables, plant height, number of leaves and leaf area, the highest corn yields for silage and total dry matter were obtained with the compost preparation Don Manuel and fertile Minco. No effect was found to the application of organic amendments in the nutritional variables of the plant. Conclusion. Forage maize production can be carried out, through organic amendments since they have generated positive effects on crop growth and production.
