Resumo: | Three experiments (E1, E2, and E3) were carried out in Mossoró, Brazil, to evaluate baby corn yield, green ear yield, and grain yield, respectively, of two corn hybrids (AG 1051 and BRS 2020), in response to detasseling (with or without tassel). A randomized split-plot block design (with hybrids defined as plots) and ten replicates was used. The three experiments were planted on the same day and in neighboring areas. In the three experiments, the hybrids did not differ from each other on the dry matter mass and number of tassel branches. In E1 (baby corn production at 180 thousand plants ha-1), for both hybrids, the following effects were observed due to detasseling: a) an increase in ear total number, in ear total weight, in marketable unhusked ears number and in marketable unhusked ears weight; b) no change was observed in the number and weight of marketable husked ears. Hybrid AG 1051 was superior to BRS 2020 for weight of marketable husked ears, but the two hybrids did not differ in other traits utilized to evaluate baby corn yield. In E2 (green ear yield at 50 thousand plants ha-1), detasseling did not change the following traits in both hybrids: total number and weight of ears; number and weight of marketable unhusked ears and marketable husked ear weight. Detasseling reduced the number of marketable husked ears in cultivar AG 1051, but not in BRS 2020. The two hybrids did not differ in total number of ears and number of marketable unhusked ears. Hybrid AG 1051 was superior to BRS 2020 in regard to the total ears weight, marketable unhusked ears weight and number and weight of marketable husked ears. In E3 (grain yield at 50 thousand plants ha-1), detasseling did not affect grain yield (RG) and hybrid AG 1051 was superior to BRS 2020 for grain yield. |
