Resumen
El experimento se efectuó en el verano del 2016, en la finca Dacrian,
parroquia La Iberia, cantón El Guabo, provincia El Oro, con el fin de
analizar el efecto de dos bioestimulantes, con tres dosis de cada uno, en el
cultivo de fréjol (Phaseolus vulgaris L.) para aumentar los rendimientos del
cultivo, en el cantón el Guabo, provincia El Oro. Para ello se trazaron los
siguientes objetivos: a) evaluar el efecto de los bioestimulantes estudiados
sobre el crecimiento y los rendimientos del cultivo, b) determinar la dosis
más apropiada de los bioestimulantes estudiados y c) identificar que
tratamiento es el más económicamente rentable.
Se utilizó el diseño de bloques completamente al azar (DBCA), con
arreglo factorial de 2 x 3, con 6 tratamientos en 3 bloques, ejecutando el
método de análisis de varianza (ANOVA), para comprobar la existencia o
no de diferencias estadísticas entre los factores y sus interacciones. Ante la
presencia de diferencias significativas se realizó la prueba de rangos
múltiples, mediante Tukey al 5% de probabilidades.
Con la investigación se llegó a las siguientes conclusiones: Los
indicadores agronómicos días a la floración, altura de la planta, peso de
100 semillas y días a la cosecha, muestran sus mejores resultados con el
bioestimulante Bayfolan Especial. Las dosis de 1,0 y 1,5 l/ha se muestran
como las más efectivas en las variables altura de la planta, días a la
cosecha, vainas por plantas, peso de 100 semillas, granos por vainas y el
rendimiento agrícola. En cuanto a las interacciones de los bioestimulantes
con las dosis de aplicación, no influyeron en ningunas de las variables
estudiadas. El tratamiento más rentable fue el 4 (Bayfolan Especial con 0,5
l/ha), que presentó la mayor tasa de retorno marginal.
The experiment was conducted in the summer of 2016, in the farm Dacrian, Iberia parish, El Guabo canton, province of El Oro, in order to analyze the effect of two bioestimulantes, with three doses of each, in the cultivation of beans (Phaseolus vulgaris L.) to increase crop yields in the Guabo canton, province of El Oro. This drew the following objectives: a.) to evaluate the effect of bioestimulantes studied on growth and crop yields, b )determine the most appropriate dose of the studied bioestimulantes c)identify which treatment is the most economically profitable. A completely randomized block design (DBCA) was used, factorial arrangement of 2 x 3, with 6 treatments in 3 blocks, executing the method of analysis of variance (ANOVA) to check whether or not statistical differences between the factors and their interactions. In the presence of significant difference multiple range test was performed by Tukey at 5% probability. With research was reached the following conclusions: Agronomic indicators days to flowering, plant height, 100 seed weight and days to harvest, show the best results with the Bayfolan Especial bioestimulante. Doses of 1.0 and 1.5 l/ha are shown as the most effective in the variables plant height, days to harvest, pods per plant, weight of 100 seeds, grains per pod and agricultural yields. Regarding bioestimulantes interactions with the application doses, had no effect on any of the variables studied. The most cost-effective treatment was 4 (Bayfolan Especial with 0.5 l/ha), which had the highest marginal rate of return.
