Abstract: O presente trabalho investigou, com as metodologias de causalidade segundo Granger e VECM, a relação entre o PIB Agropecuário brasileiro e as variáveis consumo de energia do setor, maquinário agrícola, rebanho bovino e produção de grãos no período de 1970 a 2005. O consumo de energia foi enfatizando devido à agropecuária ser produtora e consumidora desta. Os resultados apontam uma grande relação, no curto prazo, entre o PIB e o consumo de energia. Quando se considera o conjunto das variáveis encontrou-se evidência de causalidade segundo Granger, evidenciando a importância das variáveis selecionadas como variáveis explicativas do PIB agropecuário. --------------This study used Granger causality and VECM methodologies, to investigate the relationship between the Brazilian agricultural GDP (Gross Domestic Product) and energy consumption in the sector, agricultural machinery, bovine cattle and grain yield from 1970 to 2005. Energy consumption was emphasized due to the agriculture being both, producer and consumer of it. Results indicate a great relationship, in the short run, between GDP and energy consumption. When considering all the variables it was found evidence of causality according to Granger, highlighting the importance of the selected variables as explanatories of agricultural GDP.
