Resumen
El presente trabajo se desarrolló en el sector Río Negro, perteneciente al cantón
El Guabo, provincia de El Oro, el que tuvo como objetivo determinar el efecto de
biorreguladores en el desarrollo y rendimiento de pastos. Se utilizó el diseño de
bloques azar con seis tratamientos y cuatro repeticiones, en el que se ensayó
testigo 1 (pasto Pennisetum pupureum), Evergreen + Auxinas + citoquininas +
giberalinas a follaje y Fertisak elp +Auxinas + citoquininas a follaje en el pasto
Pennisetum pupureum , testigo 2 (pasto Pennisetum sp), Evergreen + Auxinas +
citoquininas + giberalinas a follaje y Fertisak elp +Auxinas + citoquininas a follaje
en el pasto Pennisetum sp. Obteniéndose como resultados que los tratamientos
no incidieron significativamente en porcentaje de brotación de estolones , en
altura de planta antes del corte y 45 días después del corte alcanzaron
significancia estadística, mientras que en el momento del corte, a los 15 y 30
días no presentaron significancia estadística, en número de hoja antes del corte
y en el momento del corte no presentaron significancia estadista, 15, 30 y 45 días
después del corte obtuvieron significancia estadística y en diámetro del tallo, en
el momento del corte a los 15 y 30 días después del corte no presentó
significancia estadística, mientras que a los 45 días después del corte alcanzo
significancia estadística. Se recomienda sembrar pasto Pennisetum sp para
incrementar los rendimientos en los lugares donde se siembra pasto y aplicar
Biorreguladores (auxina, citoquinina y giberalinas), para mejorar la producción
de forraje para obtener una rentabilidad elevada.
The present work was developed in the Río Negro sector, belonging to the El Guabo canton, El Oro province, which aimed to determine the effect of bioregulators on the development and yield of pastures. The random block design with six treatments and four repetitions was used, in which control 1 (Pennisetum pupureum grass), Evergreen + Auxins + cytokinins + giberalins to foliage and Fertisak elp + Auxins + cytokinins to foliage were tested in Pennisetum pupureum grass , control 2 (Pennisetum sp grass), Evergreen + Auxins + cytokinins + giberalins to foliage and Fertisak elp + Auxins + cytokinins to foliage in Pennisetum sp. Obtaining as results that the treatments did not significantly affect the percentage of sprouting of stolons, in plant height before cutting and 45 days after cutting they reached statistical significance, while at the time of cutting, at 15 and 30 days they did not present significance. Statistical significance, in leaf number before cutting and at the time of cutting did not show statistical significance, 15, 30 and 45 days after cutting they obtained statistical significance and in stem diameter, at the time of cutting 15 and 30 days later The cut-off did not show statistical significance, while 45 days after the cut-off it reached statistical significance. It is recommended to sow Pennisetum sp grass to increase yields in the places where grass is sown and to apply Bioregulators (auxin, cytokinin and giberalins), to improve forage production to obtain high profitability.
