Abstract

The aim of the present research is to evaluate the rate and recovery speed of stump splinters of five species of Brachiaria (B. brizantha, B. decumbens, B. humidicola, B. mutica and B. ruziziensis) in the ecological conditions of Kisangani using four randomized complete blocks experiment. The results revealed that the best recovery rate is recorded with stump splinters of B. mutica (95.5%) followed by B. humidicola (84.6%), B. decumbens and B. ruziziensis (82 and 81% respectively), while B. brizantha recovers quite difficult (62%). B. mutica recovers faster (average 11 days after planting) followed by B. decumbens, B. humidicola and B. ruziziensis (average 14, 16 and 15 days, respectively). B. brizantha recovers more slowly (on average 20 days after planting). These results indicate that under the ecological conditions of Kisangani city, B. mutica is well indicated to serve as alternative to livestock fodder especially in case of shortage due to rains late season. However, the assessment of the productivity of these different species is in progress.
