Abstract

espanolLas dimensiones y el rendimiento de los frutos son caracteristicas fundamentales para la calidad de frutos destinados al mercado y la industria. En este sentido se realizo un experimento para evaluar el formato, resistencia y rendimiento de maracuya amarillo producido en sustrato con biofertilizante bovino, mantillo e irrigado con agua salina. El diseno experimental fue de tres bloques al azar, con un arreglo factorial de 2 x 2 x 2, los factores evaluados fueron: agua de riego no salina (0,50 dS m-1), salina (4,50 dS m-1), con aplicacion y sin aplicacion de biofertilizante bovino, con y sin mantillo. Los frutos de maracuya fueron cosechados con 30% de corteza amarillenta y se evaluo el diametro de la cavidad longitudinal (largura), diametro de la cavidad ecuatorial (transversal), indice de formato de los frutos, resistencia de la cascara y rendimiento de jugo y pulpa. Los mayores valores de diametro de la cavidad longitudinal, diametro de la cavidad ecuatorial, indice de formato de los frutos y rendimiento de jugo y pulpa se obtuvieron con el uso de biofertilizante bovino y mantillo en los sustratos regados con agua de alto nivel de salinidad. El uso de agua de alto nivel de salinidad redujo el diametro de la cavidad longitudinal, el diametro de la cavidad ecuatorial, el indice de formato de los frutos, independientemente de la presencia de insumos organicos en el sustrato y aumento el rendimiento de jugo, pulpa y resistencia de la cascara en los tratamientos sin biofertilizante y sin mantillo. El mayor indice de formato del fruto presento el mayor rendimiento de jugo. EnglishThe size and yield of fruit are important in the physical quality of the fruits destined for markets and industry. An experiment was performed to evaluate the form, peel strength and yield of fruits of yellow passion fruit plant produced in substrata with bovine bio-fertilizer and mulching, irrigated with saline water. The treatments were designed in three random blocks using a 2 x 2 x 2 factorial arrangement; irrigation with non-saline (0.50 dS m-1) and saline (4.50 dS m-1) water, with and without application of bovine biofertilizer and with and without mulching. The passion fruit fruits were harvested when 30% of the peel was yellowish; we evaluated the diameter of the longitudinal cavity (length), diameter of the equatorial cavity (width), fruit form index, peel strength and juice and pulp yield. The substrate with bovine bio-fertilizer and mulching irrigated with high salinity water reduced the diameter of the longitudinal and equatorial cavity, the fruit form index and increased the firmness of the peel of the fruits of the yellow passion fruit plant. However, the use of the bovine biofertilizer and mulching irrigated with non-saline water increased the diameter of the equatorial and longitudinal cavity and the fruit form index.
