Descripción
El objetivo de la investigación en cebolla de bulbo (Allium cepa l.) híbrido Perla Linda Vista, fue mejorar el rendimiento a partir de una fertilización base al suelo de 50kg/ha de la formulación 8–20–20 complementadas con aplicaciones foliares de Biol al 10, 20, 30 y 40% a los 60, 75 y 90 días del trasplante utilizando un diseño de bloques al azar en arreglo bifactorial (4 x 3 + 1), cuatro repeticiones, con variables respuestas: altura de planta a los 60, 75 y 90 días, a la cosecha: longitud, diámetro y rendimiento de bulbos, estableciendo diferencias entre los promedios mediante Tukey al 5% de probabilidad, aplicando correlaciones y regresiones, referenciados con un estudio económico. Se estableció que el efecto del Biol sobre el rendimiento, aunque sin diferencia estadística no significativa, es mayor a dosis bajas y a épocas tempranas de aplicación posiblemente favorecidas por la etapa fenológicas llenado del bulbo. Así, se obtuvo la mejor rentabilidad con Biol al 10% aplicado a los 60 días con Tasa de Retorno Marginal de 7.8% y rendimiento de 43,489 kg ha-1, donde los coeficientes de correlación y ecuaciones de regresión de los caracteres agronómicos de la cebolla respecto a dosis y frecuencias de aplicación de Biol fueron también no significativas; por lo que se concluye que el efecto sería una respuesta de contribución a mejorar rendimientos en biomasa y calidad del bulbo.
The goal of this research was to improve the yield of bulb onion (Allium cepa l.), hybrid Cute Pearl View, using a soil base fertilization with 8-20-20 formulation at 50kg/ha, supplemented with foliar applications of Biol10 , 20, 30 and 40% at 60, 75 and 90 days after transplantation using a randomized block design with a bifactorial arrangement (4 x 3 + 1) and four repetitions. The variables assessed were: plant height at 60, 75 and 90 days, and at harvest; and length, diameter and yield of bulbs. Differences between averages were determined by the Tukey test at 5% probability, using correlations and regressions, referenced with an economic study. It was established that the biological effect on performance, although with no statistically significant difference, is greater at low doses and at earlier times of application possibly favored by the bulb-fill phenological stage. Thus, the highest profitability was obtained with Biol at 10% applied 60 days after transplanting, with a marginal rate of return of 7.8% and yield of 43.489 kg ha-1, and non-significant correlation coefficients or regression equations for the agronomic traits of the hybrid as affected by dose and frequency of Biol application; therefore it was concluded that Biol application would contribute to improve biomass yield and bulb quality.
