I. M.  aTechnology to extend soybean cultivation to the tropical savannas of Brazil.  c1997  ap.478-481.  aThe potential areas for soybean cultivation in Brazil were located in the low latitude tropical region, for which there was no technology. The Brazilian savannas (cerrados) are characterized by low fertility soil (oxisols), definite rainy season and suitable temperature for plant growth. This region has become a major grain producer in the country, responding for about 50% of national soybean production. It required a series of modifications in crop management to adapt into the new frontier. Among the major technologies are varietal selection for long juvenile period; selection of acid-soil adapted strains of nitrogen-fixing bacteria; definition of suitable sowing and havest dates; fertilization and soil management to increase production and reduce the effects of dry spells; rotation with other crops to reduce the effects of disease and pests. The present work aimed to discuss these research contributions, pointing out the possibilities of their utilization in similar regions of the world.  asoybeans  atechnology  aCerrado  aGlycine Max  aSoja  aTecnologia  aCultivation  aCultivo1 aSPEHAR, C.
