BEHAVIOR AGRONOMIC AND CHEMICAL COMPOSITION OF THREE Brachiaria VARIETIES IN DIFFERENT AGES OF HARVEST

The effect of the age (A) and the variety (V) on: plant height (PH) (cm), root longitude (cm) (RL), number of stems (NT) and leaves (NL), forage biomass (FB) (kg MS ha-1), relationship leaf stem (in number and weigh), in situ digestibility DISMS, and chemical composition of Brachiaria decumbens, brizantha and mulatto grass (ruzizienzis 44-6 x brizantha cv. Marandú), cut at the 28, 56, 84 and 112 d was evaluated. A split plot design was used. The main plot was the Brachiaria variety, and the subplots the crop age. The PH, didn’t present differences (p>0.05) among varieties. The RL presented difference (p<0.05) among variety, the best was the mulatto grass for the age 28, 56, 84 and 112 d. The biggest NT to the 56, 84 and 112 d, and NL for plant until the 84 d were obtained for mulatto. The biomass(kg MS ha-1) didn’t present significant differences (p>0.05). The mulatto grass presented the best relationship leaf/stem, to the 28, 56 and 84 d and the brizantha to the 112 d (p<0.05). The digestibility in situ diminished when increasing the age. The major percentage in MS and raw fiber, and smaller protein was presented to the 112 d.
