Rendimiento de forraje y características estructurales de Urochloa brizantha CV. insurgente cosechado a diferente edad de rebrote.

Abstract

The objective of this study was to evaluate the effect of season and regrowth age on the herbage yield, morphological composition and structural characteristics in Insurgente grass. Three regrowth age were studied (RA: 28, 35 and 42 days) in three seasons of the year (rainy, north, dry), in a completely randomized block design in a split plot array, with four replicates plots. The following attributes were taken into account, herbage yield, plant height, morphological composition and leaf: stem and leaf: no leaf ratio. The distribution of herbage yield was 30, 5 and 65 % for rainy, north and dry seasons, respectively, with an annual average accumulation of 10.869 kg DM ha- 1 and 32 cm plant height.
