Rendimiento de trébol rojo (Trifolium pratense L.) a diferente edad de cosecha.

Abstract

Objective: The objective of this research was to obtain the optimum cutting moment of the red clover by varying the cutting frequency in the spring season. Design/methodology/approach: The treatments were cuts at different ages (eight weeks) in the spring season. The variables studied were: forage accumulation, botanical and morphological composition, foliar area per stem and photosynthesis. The statistical analysis of the data obtained was performed with the GLM procedure of the SAS statistical package. The results obtained in yield of dry matter showed an increase as the age of regrowth advanced, in week 8, 5013 kg MS ha¿1 total were obtained, resulting in the maximum value registered. There was a direct positive relationship between the mass of green leaves, rate of photosynthesis, leaf area per stem and leaf: stem ratio, with the best values recorded at the fourth week of regrowth.
