Establecimiento del pasto Cuba OM-22 con la incorporación de polímeros para la retención de humedad.

Abstract

The trial was conducted at the Río Suma Experimental Farm, located in El Carmen, Ecuador, with the general objective of evaluating the effect of the use of polymers in the establishment of Cuba 22 grass (Pennisetum purpureum x Pennisetum glaucum). A completely randomized experimental design was used, with three replications and three treatments that included the incorporation of polymers for soil moisture retention. The variables evaluated included plant height, number of stems, number of leaves and stem diameter, which were measured at regular intervals until 60 days of growth. The results showed that the incorporation of polymers did not show a statistically significant impact on the morphological parameters analyzed, suggesting that polymers do not notably influence grass development. However, at 45 days, significant differences were found in the number of stems, where the treatment with hydrogel plus Biochar reached the highest average with 5 stems plant.
