The results of agroclimatic analysis, although viewed as a second approximation, indicate that in the study area there are five agroclimatic zones with growing periods varying from 200 to more than 300 days and that all agroclimatic zones experience good potential for corn, cowpea and cassava. These results indicate that cultivation of annual crops in Para State deforested area can be diversified and made less environmentally damaging if adequate crop management is provided. Included in this study is a discussion of how agrometeorological research in the region could be developed in order to provide the minimum basic information for better characterization of sites in future agroclimatic studies.  aAmazonia  aannuals  aclimatic zones  adeforestation  astatistical analysis  awater balance  aAgricultura  aAnálise Estatística  aArroz  aDesmatamento  aFeijão de Corda  aFloresta Tropical Úmida  aMandioca  aManihot Esculenta  aOryza Sativa  aProdutividade  aVigna Unguiculata  aZoneamento Climático  aAgricultural climatology  aAgroclimatic zoning  aBalanço de água  aBrasil  aClimatologia agrícola  aCultivation  aCultivo  aPará  aTropical rain forest  aYield  aZoneamento agro-climático
