Abstract
The objective of this study was to evaluate the accumulation and allocation of dry matter and nutrients by Brachiaria decumbens and ruziziensis, in three cuts, cultivated with an adequate supply of nutrients in the soil. The experimental design used was randomized blocks, with five replications, with plots consisting of five furrows of five meters in length, spaced 0.70 m apart. The average values of accumulation of Natural Matter (NM) and Dry Matter (DM) in the three cuts were, respectively, 41.0 and 6.53 t ha-1, every four weeks. There was no statistically significant difference (P≥0.05) between brachiaria; however, there was a significant effect (P≤0.05) of cutting time for forage production, since in the second cut the average production of the two brachiaria was 7.26 t of DM, surpassing in 11.77% the average of the first and third slices. In the average of the three cuts, the crude protein content of Brachiaria decumbens was 107.1 g kg-1, statistically higher than the crude protein content of Brachiaria ruziziensis (100.2 g kg-1). In the three cuts, high productivity of brachiaria decumbens and ruziziensis was observed in this intensive forage production system.
