Respuesta Agronómica de la asociación de Megathyrsus maximus y Brachiaria decumbens.

Abstract

The present graduation project was carried out due to the lack of knowledge about the behavior that grass associations can exhibit, with the aim of increasing the efficiency of biomass consumption and recovery or regrowth. In this sense, this research aimed to evaluate the agronomic response of the association of Megathyrsus maximus and Brachiaria decumbens. Additionally, the research was conducted at the La Arabia site in the Chone canton, where 3 demonstration plots corresponding to each treatment were established. In the first plot, the Megathyrsus maximus grass was established, the second with the Brachiaria decumbens grass, and the third corresponds to the association of both grasses. Thus, the current study is empirical, descriptive, and experimental. Where the evaluated variables were plant height, leaf length, number of leaves, and biomass. Once the data collection was carried out in the different demonstration plots, they were analyzed using descriptive statistics. According to each established variable, it was found that in the plant height variable, the Association treatment (37.4 c) had better performance than the other treatments. In the leaf length variable, the Association treatment (71.6 a) showed better results, and in terms of biomass, the Brachiaria grass (900 c) demonstrated a better agronomic response. It is concluded that the association between Megathyrsus maximus and Brachiaria decumbens improves the efficiency of biomass consumption and also aids in recovery or regrowth.
