Most maize cultivars have been developed for grain production. Because superior cultivars may differ in their exploiting purposes, interest has been demonstrated for the evaluation of corn cultivars with regard to their baby corn, green ear, and grain yields production ability. In the present work ten corn cultivars (AG 405, AG 1051, AG 2060, AG 6690, AG 7575, AG 8080, DKB 333 B, DKB 435, DKB 350 and DKB 747) were evaluated in the yield of baby corn, green ears and dry grains. Two experiments were carried out in the same season, in neighboring areas and managed in a similar way, in Mossoró, Rio Grande do Norte State, Brazil, in a randomized blocks design with five replicates. Baby corn yield (178,571 plants ha-1) was evaluated in one of the experiments. The other experiment (50,000 plants ha-1) was set to evaluate green ear and dry grain yield. Cultivars DKB 350 and AG 8080 were the most productive in number and weight of marketable unhusked, and husked baby corn ears. Cultivars DKB 435 and AG 8080 were the most productive in number and weight of marketable, unhusked, and husked ears. There were no differences between cultivars for grain yield.
