Productivity and coverage of alfalfa cultivars (Medicago sativa L.) of different degrees of winter rest under two cutting frequencies
The objective of this work was to evaluate the forage production and the percentage of coverage of 3 alfalfa crops with different degrees of winter rest (GRI), sometimes at two cutting frequencies for a year. Three cultivars (GR6-Verzy), (GR9-Mecha) and (GR10-Ruano) were used. The...

A. alfalfa cultivate yield cutting frequency coverage alfalfa cultivar rendimiento frecuencia de corte cobertura The objective of this work was to evaluate the forage production and the percentage of coverage of 3 alfalfa crops with different degrees of winter rest (GRI), sometimes at two cutting frequencies for a year. Three cultivars (GR6-Verzy), (GR9-Mecha) and (GR10-Ruano) were used. The experimental design was divided plots with four repetitions. Two treatments defined by the cutting intervals were established: T1: 25 days and T2: 35 days. These were specified for the spring, summer and fall seasons. In winter the interval was 45 and 55 days in T1 and T2, respectively. The variables evaluated were: forage yield per cut, leaf/stem ratio (H/T), ratio (leaf+stem)/ root (H+T)/R and the percentage of coverage under the proposed frequencies. Annual dry matter (DM) production for T1 increased. The productivity values showed no significant differences between cultivars and between treatments. Significant differe n ces were found between treatments for the H/T ratio. Interaction between cultivars and treat m ents in pasture cover was observed. El objetivo de este trabajo fue evaluar la producción de forraje y porcentaje de cobertura de 3 cultivares de alfalfa con distinto grado de reposo invernal (GRI), sometidas a dos frecuencias de corte durante un año. Se utilizaron tres cultivares (GR6-Verzy), (GR9-Mecha) y (GR10-Ruano). El diseño experimental fue de parcelas divididas con cuatro repeticiones. Se establecieron 2 tratamientos definidos por los intervalos entre cortes: T1: 25 días y T2: 35 días. Estos fueron precisados para las estaciones de primavera, verano y otoño. En invierno el intervalo fue de 45 y 55 días en T1 y T2, respectivamente. Las variables evaluadas fueron: rendimiento de forraje por corte, relación hoja/tallo (H/T), relación (hoja+tallo)/raíz (H+T)/R y el porcentaje de cobertura bajo las frecuencias planteadas. La producción de materia seca (MS) anual para T1 se incrementó. Los valores de productividad no mostraron diferencias significativas entre cultivares y entre tratamientos. Se hallaron diferencias significativas entre tratamientos para la relación H/T. Se observó interacción entre cultivares y tratamientos en la cobertura de la pastura.
