Evaluación del comportamiento morfológico y agronómico del pasto Cuba 22 (Pennisetum purpureum x Pennisetum glaucum), en la "Hacienda la Conquista" del cantón San Vicente en el año 2024.

Abstract

The present research was conducted at Hacienda La Conquista, located in San Vicente canton, to evaluate the morphological behavior and productivity of Cuba 22 grass (Pennisetum purpureum x Pennisetum glaucum) over an area of 2,500 square meters. Mechanical cleaning of weed species was carried out, followed by pre-cultivation tasks such as plowing, loosening, and leveling, before proceeding with sowing in double rows with a spacing of 80 cm between furrows. The crop was irrigated by sprinklers three times a week until the rainy season, during which irrigation was suspended. Weed thinning was performed every 20 days. Morphological characteristics were determined by randomly sampling 15 plants, obtaining average values as follows: leaf length 120.20 cm, leaf width 4.19 cm, number of leaves per plant 8.40, plant height 180 cm, and number of nodes per plant 4.11. Regarding green biomass, production reached 11,758 kg/ha, and the dry matter percentage averaged 16.8%, resulting in a total of 1,978.87 kg of dry matter per hectare.
