Época de semeadura de híbridos de milho forrageiro colhidos em diferentes estádios de maturação

Abstract: Resumo: Época de semeadura e ponto de corte de plantas de milho forrageiro são fatores importantes na produção de forragem de alto rendimento. O objetivo deste trabalho foi avaliar a participação dos componentes da planta em diferentes épocas de semeadura e estádios de colheita, em híbridos comerciais de milho recomendados para produção de forragem. O delineamento foi em blocos casualizados, com três repetições, esquema fatorial 4x2, sendo quatro híbridos de milho (P30B39H, DKB245, 2B688H e DKB330Y) e duas épo… Show more

“…Thus, it was evident that the agronomic and bromatological characteristics of the grain corn hybrids are influenced by the cultivation environment, depending on the genetic basis of the genotypes, and exhibit different behavior when submitted to different environmental conditions. Similar results were observed by Domingues et al (2013), Zsubori et al (2013) and Mendes et al (2015), who evaluated corn hybrids of different grain textures in distinct environments, noting differences between sites in term of the expression pattern of agronomic and bromatological characteristics of corn grains. Corona et al (2006) claimed that the agronomic and nutritional performance of grains is dependent on the genetic background used, which was in accordance with the results obtained in this study.…”

“…Grain corn is a component that comprises approximately 40% of the dry matter of the silage (Pereira et al, 2012;Domingues et al, 2013;Mendes et al, 2015); thus, variations on the digestibility of this portion will certainly affect the final product digestibility, a factor required for obtaining good results.…”

“…O florescimento masculino (estádio VT) foi considerado segundo (Wordell Filho & Chiaradia, 2016, p. 28) quando, no mínimo, 50% das plantas da parcela emitiram o pendão. Os demais caracteres agronômicos foram avaliados no PCS: "meia linha do leite", com o grão leitoso a farináceo (entre os estádios R4 e R5), considerado o ponto ideal (MENDES et al, 2015) .…”

“…Outro fator que torna importante a avaliação da digestibilidade da planta inteira como critério de seleção em programas de melhoramento é a sua herança ser influenciada em maior magnitude por efeitos aditivos, evidenciando maior possibilidade de êxito na obtenção de genótipos superiores a partir do cruzamento de genitores com elevado desempenho para o caráter (Gralak et al, 2014;Mendes et al, 2015).…”
