Evaluación de tres variedades de pastos Sofial, Bijou y Virazón en la Estación Agropecuaria de la Universidad Técnica Particular de Loja (UTPL)

Abstract

Abstract: This study was conducted at the Agricultural Station of the Private Technical University of Loja (UTPL), and its purpose was to determine the agronomic properties and nutritional value of three different forage grass varieties: Sofial, Bijou, and Virazón. A randomized complete block design was used. Variables such as health, proximate composition, and biomass yield were assessed, as well as height, number of leaves, stem diameter, and tillering strength. Eight cuttings were performed, each at intervals of 30 to 45 days; dry matter and nutritional value were determined in terms of metabolizable energy, fiber, and protein. These results showed that the Virazón variety stood out for its greater height and average biomass gain, making it ideal for cutting systems. The Sofial variety showed better performance in terms of nutritional quality, with higher crude protein and soluble solids content, which is suitable for intensive dairy production systems. Finally, the Bijou variety showed good digestibility and regrowth vigor, so it can be used in rotational grazing pastures.
