Abstract:
Legume tissue quality is a key factor for enhancement of feed resources and contribution to soil fertility in mixed crop-livestock production systems. Methods used by soil scientists and animal-nutritionists to assess quality were compared on three tree legumes. The extent of decomposition and gas production were
Indigofera> Cratylia> Calliandra. Results showed that differences in decomposition and digestibility were more related to intrinsic plant quality parameters than to changes in tissue quality induced by post harvest treatments. This study confirms the potential usefulness of in vitro dry matter digestibility (IVDMD) for screening tropical legumes for soil fertility management.
