Desempenho agronômico em cultivares de Milho verde no Ecótono Cerrado-Amazônia

Abstract

Zea mays L. maize, is a plant of the Poaceae family, originating in Central America, considered one of the oldest cultivated plants and one of the most studied vegetables, developing a more detailed genetic aspect as cultivated species (LOPES et al., 2019) , the objective of this work was to study the agronomic performance in green corn cultivars in the Cerrado-Amazon ecotone. The tests were conducted in the 2017/18 harvest on a property in the state of Pará. The design used in the given experiment was randomized blocks (DBC) and 3 replicates. An experimental plot consisted of 4 rows of 5.0 m spaced 0.9 m between rows, being considered a useful area as two central rows. The characteristics to evaluate agronomic performance were: ear height (cm), plant height (cm), ear length (cm), ear diameter (mm), number of grains per row, grain weight in (g), ear with straw and ear without straw. All genotypes taken had agronomic aptitude for green corn production in the Cerrado-Amazon ecotone region in the state of Pará. The cultivars BRS 3046 and BM 3051 independent the best performance for most of the evaluated characteristics.
