Other economic and sociocultural factors such as: income, off-farm income, credit, farm size, size of herd, land under cultivation, labour, age, literacy, education, place of birth, and years of residence in the Federal District, were also analysed, and their influence on adoption of innovations was assessed. Farmers interviewed were divided into three main groups: 1) crof farmers, 2) livestock farmersm, and 3) farmers dealing with both crop and animal husbandry. Into the Federal District farmers are, in their majority, literate, with many years of formal education. They come from the several regios of Brazil, from Japan, and other countries. Crop farmers tend to live mainly off the farming activity, while livestock farmers live primarily from their off-farm activity. They do not have very large farm units. Crop farmers rely more heavily on credit, but for livestock farmers, credit is largely unavailable. The degree of influence of informational, economic, and socio-cultural factors on adoption varied the type of activity. Informational factors were the most important predictors for adoption by crop farmers, and economic factors were the most important for livestock farmers. For farmers dealing with both activities, the socio-cultural factors were the most imporant in explaining adoption of crop innovations whiole the economic factors were the most important in explaining adoption of animal husbandry innovations. Both mass media and interpersonal channels of communication proved to be important predictors for adoption of crop innovations, although their roles varied. Inrterpersonal channels of communication played and important role in helpin farmers to get aware of the new agricultural methods and practices, while use of mass media was actually the most important predictor in explaining adoption of crop innovations. The nature and characteristics of the innovations were found to be main determinants of adoption. aagriculture aBrazil ainformation amass media atechnology atechnology transfer aAdoção de Inovações aAgricultura aCerrado aExtensão Rural aInovação aTecnologia aTransferência de Tecnologia aAdocao aAdoção de tecnologias agrícola aAdoption aBrasil aBrazilian savannas aCanais de comunicação aCommunication aDistribuíção Federal aDistrito Federal aInfluência aInformação aInformation tranferred aInnovation aInovation adoption aInterpersonal channels aRural extension aTranferência de informação aTransferencia aTransferencia de informacao
