In tropical Africa, the most common and most extensively evaluated Brachiaria species as cultivated pastures are B. brizantha, B. ruziziensis, B. decumbens, and B. mutica. In recent years, B. dictyoneura cv. Llanero, B. humidicola, and B. platynota have also received increased attention. The firs...
This paper reviews published and unpublished information on the physiological and agronomic characteristics associated with the widespread adaptation of Brachiaria species. Adaptation to shade, drought, flooding, rainfall, and defoliation are discussed. Strong regrowth under frequent defoliation ...
