Producción de biomasa del pasto Guatemala (Tripsacum laxum) a tres edades de corte en época de escasez hídrica.

Abstract

The biomass production of Guatemala grass at three harvesting ages during periods of water scarcity is a research topic addressing the response of this grass species to specific cutting conditions in the context of limited water availability. Biomass, representing the amount of organic matter produced, is a crucial indicator in assessing pasture productivity, especially under water stress conditions. This study aims to comprehend how cutting frequency at different ages affects the ability of Guatemala grass to produce biomass during water scarcity periods. Such an approach is essential for the sustainable management of pastures in regions prone to challenging climatic conditions. The overarching objective of this research is to assess the impact of the harvesting age of Guatemala grass on biomass production. To achieve this purpose, specific objectives include determining the production of green matter in tons per hectare (t/ha-1) at three cutting ages, estimating the percentage content of dry matter in those conditions, and establishing dry matter production in tons per hectare (t/ha-1). These objectives will provide a detailed understanding of how variability in cutting age influences Guatemala grass biomass.
