Brasília, DF: SBZ, 2012. 28 f. 1 CD-ROM.c2012  aAbstract - Forage legumes have the potential to contribute substantially to warm-season, sub-tropical, and tropical pastures and rangelands. Compared to grasses, they have advantages in accessing sub-soil nutrients and moisture; legumes typically concentrate protein in forage, even in infertile soils; and they can also provide ruminants with plant proteins and soluble carbohydrates that increase digestibility of grasses when consumed in legume-grass mixtures. Yet their inclusion in warm-season, sub-tropical or tropical pasture seed mixes or rangeland rehabilitation is minimal when one considers the percent of grasslands coverage in these regions. Why have past diligent attempts failed to develop the germplasm, agronomic techniques, and dissemination to land managers in regions where these legumes are widely adapted? Successful forage legume stories indicate that farmer´s participatory approach, persistence with minimal management, seed supply after releasing new varieties, meeting the farmer´s needs, delivery of clear benefits and profits, and communication among researchers, extension and stake holders are crucial. Thus, we should establish future forage legume programs based on past learning of successful cases.  aGrasslands  aGrazing  aMixed grazing  aNitrogen fixation  aMixed pasture  aResource1 aDUBEUX JUNIOR, J.
