La introducción de leguminosas exóticas (Trifolium repens) en pajonales de puna húmeda mejora la calidad forrajera, demandando un manejo agronómico adecuado para evitar que la leguminosa exceda límites y afecte la integridad del ecosistema natural. El objetivo fue determinar la influencia de la fertilización fosfatada y densidad de siembra (leguminosa) sobre la proporción gramínea – leguminosa, en un pajonal dominado por Festuca dolichophylla y Calamagrostis vicunarum, durante dos años, a partir de los porcentajes de sobrevivencia, establecimiento y cobertura relativa de trébol blanco, en un área experimental ubicada en la Región Huancavelica de Perú (4 500 msnm). Se utilizó el DCA con arreglo factorial 3x2, con tres dosis de fósforo (0, 15 y 30 g de roca fosfatada) y dos densidades de siembra (20 y 40 semillas por hoyo). La mejor respuesta a la fertilización se obtuvo ...

Aims: determine the composition and floristic diversity, the similarity between sites based on the distribution of species in the altitudinal gradient, and determine the value of ecological importance, in Andean grassland ecosystems. Study Design: Original research. Place and Duration of Study: This study took place in the Huacracocha micro-watershed in the Central Highlands of Peru, during the rainy season (January - March 2022). Methodology: The agrostological evaluation points were determined taking into account twelve sites of interest were determined, located from the lowest part of the micro-watershed (4091.8 masl) to the part with the highest vegetation cover (4512.27 masl), the agrostological reading process at each evaluation site was carried out using the radial transect method with the line and intercept point technique. Results: We observed the presence of the presence of 78 ...
