Morfogênese de capim-canarana com duas frequências e duas intensidades de desfolhação

Abstract: Objetivou-se avaliar o fluxo de biomassa do capim-canarana erecta lisa (Echinochloa pyramidalis LAM.) pastejado por novilhas leiteiras num delineamento em blocos casualizados com cinco repetições (piquetes) e arranjo fatorial 2 x 2 (frequência e intensidade). As frequências de desfolhação (FD) corresponderam à intercepção de 85 e 95% da radiação fotossinteticamente ativa e as intensidades de desfolhação (ID) corresponderam aos índices de área foliar residual 1,0 e 2,0. Foram avaliadas as seguintes variáveis: a… Show more
