The aim of this study was to evaluate the productive performance and nutritional value of seven clover genotypes at three altitude levels (PA I: 2300-2800 m above sea level, PA II: 2801-3300 and PA III: 3301-3800) of the northern highlands of Peru during a year. Four genotypes of white clover (Trifolium repens) and three genotypes of red clover (Trifolium pratense) were installed in each altitudinal floor (PA). The germination power, weight and purity of the seeds were evaluated to ensure the viability of the number of seeds sown. The yield (kg DM ha-1 year-1), growth rate (kg DM ha-1 day-1), plant height (cm) and nutritional value for each genotype were determined. The highest yields and the best growth rates (p<0.01) in the three PAs corresponded to the three varieties of Trifolium pratense (Tuscan, Americano and Rel...

El objetivo del estudio fue evaluar el comportamiento productivo y el valor nutricional de siete genotipos de trébol en tres niveles de altitud (PA I: 2300-2800 msnm, PA II: 2801-3300 msnm y PA III: 3301-3800 msnm) de la sierra norte de Perú durante un año. Se instalaron cuatro genotipos de trébol blanco (Trifolium repens) y tres genotipos de trébol rojo (Trifolium pratense) en cada piso altitudinal (PA). Se evaluó el poder germinativo, peso y pureza de la semilla para asegurar la viabilidad del número de semillas sembradas. Se determinó el rendimiento (kg MS ha-1 año-1), tasa de crecimiento (kg MS ha-1 día-1), altura de la planta (cm) y valor nutricional para cada genotipo. Los rendimientos más altos y las mejores tasas de crecimiento (p<0.01) en los tres PA correspondieron a las tres variedades de Trifolium pratense (Tuscan, Americano y Relish). El PA I (p<0.01) obtuvo la ma...
