Abstract
El objetivo principal de esta investigación fue evaluar el efecto de cinco diferentes tipos de sustrato para el cultivo de palta (Persea americana Mill. var Zutano) en condiciones de vivero, teniendo en cuenta parámetros como el diámetro de tallo y la altura de la planta. El análisis de los datos se realizó inicialmente mediante la prueba de análisis de varianza (ANOVA) con un diseño completamente al azar con 5 tratamiento y 4 repeticiones. Además, para la comparación entre grupos de tratamiento se realizó la prueba de comparaciones múltiples de Tukey considerando un 95% de probabilidad. Los resultados mostraron que, el tratamiento T3 que contenía como sustrato 50% de suelo agrícola, 33,33% de arena de río y 16,7% de turba, obtuvo la mayor altura de la planta a los 120 días de cultivo, con una media de 40,4925 cm. En relación al diámetro, el tratamiento T3 también obtuvo la media superior con valor de 0,71775 cm. Por otro lado, el tratamiento T4 (50% suelo agrícola, 10% arena de rio, 15 % cascarilla de arroz, 25% humus) obtuvo la media superior en el conteo de hojas con un valor promedio de 19.575 , seguido por el tratamiento T3 con una media de 18.475. En conclusión, de los 5 tipos de sustratos evaluados, el tratamiento T3 (50% tierra agrícola, 33.33% de arena de río, 16.67% de turba) fue el más eficiente para el cultivo de palta (Persea americana Mill. var Zutano) en condiciones de vivero debido a que fue el mejor en obtener los mayores parámetros en altura, diámetro de planta y número de hojas.
ABSTRACT The main objective of this research was to evaluate the effect of five different types of substrate for the cultivation of avocado (Persea americana Mill. var Zutano) under nursery conditions, taking into account parameters such as stem diameter and plant height. The data analysis was initially carried out using the variance analysis test (ANOVA) with a completely randomized design with 5 treatments and 4 repetitions. In addition, for the comparison between treatment groups, the Tukey multiple comparison test was performed considering a 95% probability. The results showed that the T3 treatment, which contained 50% agricultural soil, 33.33% river sand and 16.7% peat as substrate, obtained the highest plant height at 120 days of cultivation, with an average of 40.4925 cm. In relation to the diameter, the T3 treatment also obtained the highest average with a value of 0.71775 cm. On the other hand, treatment T4 (50% agricultural soil, 10% river sand, 15% rice husk, 25% humus) obtained the highest mean in leaf count with an average value of 19,575, followed by treatment T3 with an average of 18,475. In conclusion, of the 5 types of substrates evaluated, treatment T3 (50% agricultural soil, 33.33% river sand, 16.67% peat) was the most efficient for the cultivation of avocado (Persea americana Mill. var Zutano) under nursery conditions because it was the best in obtaining the highest parameters in height, plant diameter and number of leaves.
