In corn, when the first female inflorescence is removed, the plant often produces new female inflorescences. This allows the first ear to be harvested as baby corn (BC) and the second as green corn (GC) or dry corn (DC), that is, mature corn. The flexibility provided by a variety of harvested products allows the grower to compete with better conditions in the markets. We evaluated BC, GC, and DC yields in corn cultivars AG 1051, AG 2060, and BRS 2020, after the first ear was harvested as BC. A random block design with ten replicates was utilized. The yields of MM, MV and MS were higher when these products were individually harvested than when they were harvested in combination with baby corn (BC + GC and BC + DC). Cultivar BRS 2020 was the best for producing BC exclusively, considering the number and weight of marketable unhusked ears and the number (NH) of marketable husked ears. Considering weight (WH) of BC marketable husked ears, cultivar AG 1051 was the best. Cultivars did not differ in baby corn yield when this product was harvested in combination with MS or MV, except with regard to NH and WH, with AG 1051 being superior. The cultivars did not differ between total number of ears and number of marketable unhusked green ears. However, cultivars AG 1051 and AG 2060 were the best with respect to marketable unhusked green ears and number and weight of marketable husked green ears. Cultivar AG 1051 was the best with regard to kernel yield.
