Resumen
La investigación se realizó en la finca del Señor Víctor Rivas, la cual
está situada en la hacienda El Triunfo, vía Las Maravillas del cantón Daule,
provincia del Guayas Los objetivos planteados fueron: a) Comparar el efecto
de las tres dosis del biofertilizante en las variables de producción y
fisiológicas del cultivo; b) Determinar la mejor dosificación estudiadas del
biofertilizante y c) Estimar el impacto económico entre los tratamientos
estudiados.
Se utilizó el producto comercial BIO EZKUDO con cuatro dosis de
aplicación, el diseño fue completamente al azar, en total resultaron cuatro
tratamientos con cinco repeticiones para cada uno de ellos; se midieron siete
variables agronómicas y se realizó análisis de presupuesto parcial.
El análisis de presupuesto de acuerdo a CYMMIT, ajustado al 5% en
función del rendimiento en kg por hectárea, detalla que el tratamiento cuatro
obtuvo el mayor beneficio bruto 3668 USD/ha. Mientras que en los
beneficios netos el mismo tratamiento alcanzó el mayor valor con 3615
USD/ha y el que obtuvo el menor valor fue el tres con 2448 USD/ha. Según
el cuadro 9 no existe dominancia entre los tratamientos. En el análisis
marginal obtenido en el ensayo el tratamiento cuatro obtuvo el mayor
beneficio neto marginal con 699 USD/ha, mientras que el tratamiento antes
mencionado obtuvo la mejor tasa de retorno marginal con 23301%.
Se concluyó que: • Comparado el efecto de las diferentes dosis de
biofertilizantes dentro del cultivo estas influyeron sobre las variables
fisiológicas: número de hojas por planta, diámetro del fruto (cm), longitud del
fruto (cm) y peso del fruto (g), el mayor rendimiento medio se presentó en el
tratamiento cuatro con 10.19 (t/ha), la mejor dosis de aplicación fue 150 cm3
de biofertilizantes por ha, el tratamiento cuatro es el más rentable
económicamente con beneficios bruto de 3668.6 USD/ha.
The following was carried out in the farm of Mr. Victor Rivas, which is located in “El Triunfo” farm, on the road las Maravillas , Daule canton, Guayas province. The objectives were: a) To compare the effect of the three doses of biofertilizer on the Production and physiological variables of the crop; B) to Determine the best dosage of the bio - fertilizer under study and c) To estimate the economic impact among the treatments studied. The commercial product BIO EZKUDO was used with four doses of application, the design was completely at random, in total four treatments were obtained with five replicates for each of them; Seven agronomic variables were measured and a partial budget analysis was performed. The budget analysis according to CYMMIT, adjusted to 5% according to the yield in kg per hectare, details that were obtained in treatment four with the highest gross profit 3668 USD / ha. In terms of the net benefits the same treatment reached the highest result with 3615 USD / ha and the one that obtained the lowest result was treatment three with 2448 USD / ha. According to Table 9, there is no dominance between the treatments. In the marginal analysis obtained in the trial treatment four obtained the highest marginal net benefit with 699 USD / ha, treatment mentioned above obtained the best marginal rate of return with 23301%. It was concluded that: • Comparing the effect of the different doses of bio fertilizers in the crop, they influenced on the following physiological variables: number of leaves per plant, fruit diameter (cm), fruit length (cm) and fruit weight, the highest yield was presented in treatment four with 10.19 (t / ha), the best application rate was 150 cm3 of bio fertilizers per ha, treatment four is the most economically profitable with benefits of 3668.6 USD / ha.
