          Abstract

          The need for more efficient nutrient use in adverse conditions, such as droughts, facilitated the development of new alternatives for fertilizer application, such as direct insertion into the vascular system of the pseudostem of harvested banana plants (Musa AAA Simmonds), considering the plant interconnection between the mother plant and the sucker in succession. The objective of this study was to evaluate the effect of fertilizer insertion into the pseudostem of banana plants compared to the conventional soil fertilization system. The study was conducted at two locations (north and center of Urabá region), setting different rates of fertilizer treatments (75, 100 and 125% of the commercial rate) inserted at different heights (0.6 m and 0.9 m) with a soil application of fertilizers as a control treatment. Biometric (height, pseudostem diameter, number of leaves), physiological (specific leaf area and specific leaf weight), and production variables were evaluated in the plants. According to the results, it was evident that the 0.9 m insertion height of the fertilizer was better than 0.6 m and the soil application. Although no significant differences were found between doses of fertilizer, we observed a trend of better performance for plants in treatments of 75% and 100% fertilizer dose inserted at 0.9 m

          La necesidad de hacer más eficiente el uso nutrientes en condiciones adversas como la sequía ha permitido el desarrollo de nuevas alternativas de aplicación de fertilizantes como la inserción directa al sistema vascular del seudotallo o "troncón" de la planta cosechada del banano (Musa AAA Simmonds), teniendo en cuenta la intercomunicación que existe entre la planta madre y el hijo en sucesión. El objetivo del ensayo fue evaluar la eficiencia de inserción del fertilizante al troncón comparado con la fertilización edáfica convencional. El ensayo se realizó en dos localidades (zona norte y centro) de Urabá (Colombia), con cuatro dosis de fertilizante (75, 100 y 125% de la dosis comercial y fertilización edáfica) insertadas en el seudotallo a 0,9 y 0,6 m. Se tomaron variables de crecimiento (altura, diámetro del seudotallo, número de hojas), fisiológicas (área foliar específica, peso foliar especifico) y producción. La inserción del fertilizante a 0,9 m fue más efectiva que a 0,6 m y que la fertilización al suelo. Aunque no se evidenciaron diferencias significativas entre las dosis de fertilizante, se pudo observar una tendencia de mejor comportamiento de las plantas en los tratamientos de 75 y 100% de la dosis comercial insertados a 0,9 m
