This research evaluated the effect of nitrogen fertilization (0, 161, 321.8, or 483 kg ha-1) on the accumulation of Fe, Cu, Zn, Mn, and B in banana plants cv. Williams in two production cycles in Uraba, Colombia. The micronutrient accumulation models for the plants were obtained with a multivariate approach for differences between cycles, using a randomized complete block design with repeated measurements over time. The N doses with greater accumulation of Cu, Fe, Mn, Zn and B in the plants with fruits were 321.8 and 483 kg ha-1. The average sequence of micronutrient extraction by whole plants was Fe>Mn≥Zn>B>Cu in the first cycle and Fe>Cu>Mn≥Zn>B in the second cycle. The micronutrient accumulation was organ-specific and varied depending on the stage of development. Fe was the major micronutrient extracted by the corm, pseudostem, and bunch. The leaves had the greatest accumulation of Mn. The higher fertilizer doses generated a major response in terms of micronutrient extraction by the banana plants.

Fate of a 15N-labeled Urea Pulse in Heavily Fertilized Banana Crops

et al. 2020

Banana crops in the Caribbean are characterized by the use of high rates of nitrogen (N) fertilization which causes severe environmental damages. The aim of this study was to assess the fertilizer N use efficiency (NUE) of banana crops in the field. To do so, a field trial was carried out during the first (GS1) and the fourth (GS4) growing seasons of banana crops, and the fate of a 15N-labeled pulse applied late in the growing season (flowering stage) was determined. At harvest, NUE (average 24% 15N applied) and the total recovery of fertilizer 15N in the soil–plant system (i.e., 40% in GS1 and 62% in GS4) were low. Low NUE resulted mainly from the dilution in a large soil mineral N pool derived from earlier applications of the labeled-N fertilizer applied at flowering, combined with leaching caused by numerous high-intensity rainfall events (>20 mm d−1). Crop residues from previous cycles present at time of fertilizer application in the fourth growing season, promoted fertilizer N immobilization, which in turn favored fertilizer N recovery by decreasing N leaching. The results suggest that N fertilization after the first season could be reduced by 30% (i.e., −90 kg N ha−1) corresponding to the suppression of two applications from flowering to harvest with the current fertilizer management, as available N derived from earlier applications is sufficient to meet plant requirements.

El arándano azul tipo Ojo de Conejo (Vaccinium ashei Reade) se ha convertido en una excelente alternativa para diversificar la actividad frutícola en México, desafortunadamente, su reciente introducción está acompañada de escasa información en su manejo agronómico, destacando el desconocimiento de las demandas nutrimentales del cultivo. Con el objetivo de conocer la dinámica nutrimental en las hojas y frutos durante las diferentes etapas de desarrollo del mismo, e identificar las etapas críticas de los diferentes nutrimentos, en una plantación de arándano tipo Ojo de Conejo en Zacatlán, Puebla, se recolectaron muestras de hojas y frutos en cinco etapas de desarrollo del fruto: fruto verde, cambio de color de verde a rosa (V-Rs), inicio de maduración (fruto rosa-rojo, Rs-Rj), durante la maduración (fruto rojo-azul, Rj-A) y fruto maduro (azul). Se determinó la concentración de macro y micronutrimentos. En las hojas, la concentración de todos los elementos mostró dos picos, uno en la etapa de fruto verde y el otro cuando el fruto alcanzó su madurez (fruto azul). El orden de concentración en las hojas fue: N>Ca>K>Mg>P>Fe>Mn>B>Zn. La concentración de todos los elementos en los frutos presentó un descenso con el avance de la maduración. El orden de concentración nutrimental en los frutos fue: N>K>Ca>Mg>P>Zn>B>Mn>Fe. Estos resultados indican que las etapas de mayor demanda nutrimental son las dos primeras (fruto verde y V-Rs). Por lo que los elementos se deben suministrar en la floración, previo al desarrollo del fruto para garantizar una producción y calidad del fruto satisfactorias.
