dc.description.abstractPlantains (Musa accuminata x Musa balbisiana) are one of the most important commercial crops cultivated in Puerto Rico. It is important to determine the optimum fertilizer nitrogen (N) rates for the optimum yields, decrease production costs and excess N. An experiment was conducted in a commercial farm in the southern semiarid coast of Puerto Rico. The soil was of the Cartagena series (Fine, mixed, superactivate isohypertermic Sodic Haplusterts). Crop response to four N levels (100, 200, 300 and 400 kg/ha) applied as urea and ammonium sulfate by fertigation was evaluated. There were no significant differences between the treatments for total number fruits (132,969 fruits/ha), number of commercial fruits (81,957 fruits/ha), number of noncommercial fruits (49,976 fruits/ha), total weight (44,992 kg/ha), weight of commercial fruits (29,331 kg/ha), weight of noncommercial fruits (12,833 kg/ha), weight of total fruit (353 g/fruits), weight of commercial fruit (358 g/fruits) and weight of noncommercial fruit (253 g/fruits). The lack of response to fertilizer N could be due to residual soil N and the capacity of the soil to supply N. The suggested fertilizer N level for plantain production in similar soils and crop management as the one used in this study in the southern semiarid coast of Puerto Rico is 100 kg N/ha.en_US
dc.description.abstractEl plátano (Musa accuminata x Musa balbisiana) es uno de los cultivos de mayor importancia en Puerto Rico. Es de importancia determinar el nivel óptimo de aplicación de nitrógeno (N) para maximizar la producción y minimizar costos y pérdidas de nitrógeno. Se estableció un experimento en un suelo de la serie Cartagena (Fine, mixed, superactive isohypertermic Sodic Haplusterts) para evaluar la respuesta del plátano a cuatro niveles de N (100, 200, 300 y 400 kg/ha) aplicados como urea y sulfato de amonio por fertigación. No se encontraron diferencias significativas entre los tratamientos y el número de frutos totales (132,969 frutas/ha), número de frutos comerciales (81,957 frutas/ha), número de frutos no comerciales (49,976 frutas/ha), peso total (44,992 kg/ha), peso de frutas comerciales (29,331 kg/ha), peso de frutas no comerciales (12,833 kg/ha), peso por fruto total (353 g/fruto), peso por fruto comercial (358 g/fruto) y peso por fruto no comercial (253 g/fruto). La falta de respuesta a la aplicación de N pudo ser por el N residual del suelo y la capacidad del suelo para suplir N. La recomendación de fertilización para la producción de plátanos en un suelo y el manejo del cultivo similar utilizado en este experimento en la costa semiárida del sur de Puerto Rico es de 100 kg N/ha.en_US
