The main objective of this work was to evaluate 20 forage sorghum varietiesin different environments, being five in Pernambuco and two in Alagoas, to recommendation.The cultivars were evaluated through the plant height, dry matter yield and water use efficiencyparameters. The experimental design was randomized blocks. The variance analyses werecarried out individually for environments, and grouping analyses for Pernambuco and Alagoas separately. The main conclusions were that the dry matter production and water use efficiencyparameters, when associated to each other, seemed to be appropriate for the forage sorghumvarieties selection under semi-arid conditions; the CSF11 and CSF12 varieties presented highperformance in all of Pernambuco and Alagoas environments, when compared to the others.
