Baby corn is the name given to the female inflorescence of maize before pollination, that is, it is the ear of corn in development harvested two to three days after the issuance of the styles-stigmas. With a fine, delicate texture and sweet taste, the baby corn has become a promising product for the domestic and foreign market, especially since in Brazil the processed product was mostly imported from Thailand. The objective of this work was to perform productive analysis of maize genotypes for the production of baby corn in organic production system. The experiment was conducted at the Alegre campus of the IFES, with a randomized block design with seven genotypes in four replicates. The Alliance creole variety and the double hybrid BM 207 presented the highest yields of commercial ears, with an average of 2.92 t ha-1, and a higher number of commercial ears (365,495 ears ha-1). Although the creole Alliance variety did not present a final stand of plants within the ideal range for corn production, it had a prolific behavior with one of the highest number of ears per plant (3.35 ears plant-1) and besides the largest lengths of commercial ears (8.10 cm). In view of the data obtained, the creole Alliance variety is a great option to be used by small producers due to their low cost of seed acquisition and also because they have a wide adaptation in systems of low level of technological investment besides maintaining the genetic variability in the natural conditions of cultivation.
