Evaluation of the morphological and agronomic performance of Cuba 22 grass (Pennisetum purpureum × Pennisetum glaucum).

Abstract

This article was conducted at the “La Conquista” farm in the San Vicente canton, where Cuba 22 grass not only emerged as a technical solution to livestock feeding problems but also brought with it challenges in planning, management, and sustainability. In this way, the main objective was established to evaluate the morphological and agronomic performance of Cuba 22 grass at the “Hacienda La Conquista” in the San Vicente canton. In this regard, research methods such as literature review and observation were employed. Additionally, a descriptive analysis was conducted using the Infostat statistical software to process and analyze the collected data, considering variables related to morphology and production. In this way, results such as the average leaf length was 120 cm were obtained. 20 cm, with a standard deviation of 7. 96 cm and a coefficient of variation (CV) of 6. 62%, in addition to the dry matter result, where the mean obtained was 1.978. 87 kg/ha, which is approximately 16. 8% of the green biomass yield. In this context, it was concluded that Cuba 22 grass grows at a regular rate in height and leaf length. To improve a plant’s performance, you can modify its leaf width and node production. This is achieved by adjusting certain practices such as fertilization and water management, which affect dry matter accumulation and final yield.
