Abstract
La investigación denominada Efectos de la aplicación de diferentes niveles de fertilización potásica en el rendimiento y la calidad de frutos en el cultivo de pimiento (Capsicum annum L.) Var: Híbrido Nathalie, en el distrito de Pilar, año agrícola 2017/2018, fue presentada a la Facultad de Ciencias Agropecuarias y Desarrollo Rural, Universidad Nacional de Pilar. Investigación de tipo experimental, enfocado a la evaluación de diversos parámetros en la producción de pimiento de la variedad Híbrido Nathalie, con aplicación de diferentes niveles de fertilización potásica, los resultados obtenidos valorar la influencia de dichos tratamientos en la calidad y el rendimiento del cultivo de pimiento. Las dosis utilizadas fueron las siguientes 50, 75, 100, 125, y 150 kg/ha, incluyendo un testigo el cual fue el tratamiento sin aplicación de fertilizante potásico, contando así con seis tratamientos y cinco repeticiones distribuidos en bloques al azar. Dicho análisis se comprobó con pruebas estadísticas, análisis de la varianza y la comparación de medias a través de la prueba de Duncan al 5%. Respecto a la calidad, las medias de longitud, diámetro y grosor de pared del fruto no presentaron grandes diferencias, destacando que el T4 (100 Kg/ha) siempre presentó un nivel superior entre los tratamientos, y en cuanto al rendimiento el análisis de varianza arrojó que no existe diferencia significativa entre los tratamientos, sin embargo, el T4 tuvo el mayor rendimiento con 55.225 Kg/ha donde la comparación de medias indicó que presentó diferencia significativa sobre el testigo.
The investigation called Effects of the application of different levels of potassium fertilization on the yield and quality of fruits in the cultivation of pepper (Capsicum annum L.) Var: Híbrido Nathalie, in the district of Pilar, agricultural year 2017/2018, was presented to the Faculty of Agricultural Sciences and Rural Development, National University of Pilar. Experimental research, focused on the evaluation of various parameters in the production of the hybrid Nathalie variety pepper, with the application of different levels of potassium fertilization, the results obtained assess the influence of said treatments on the quality and yield of the crop of pepper. The doses used were the following 50, 75, 100, 125, and 150 kg / ha, including a control which was the treatment without application of potassium fertilizer, thus having six treatments and five repetitions distributed in random blocks. This analysis was verified with statistical tests, analysis of variance and the comparison of means through the Duncan test at 5%. Regarding quality, the means of length, diameter and wall thickness of the fruit did not show great differences, highlighting that the T4 (100 Kg / ha) always presented a higher level between the treatments, and in terms of yield the analysis of variance showed that there is no significant difference between the treatments, however, the T4 had the highest yield with 55,225 Kg / ha where the comparison of means indicated that it presented a significant difference over the control.
