Abstract: Palavras chave adicionaisAdubação. Brachiaria brizantha. Composição morfológica. Índice de área foliar. Pastagem.resUMo Objetivou-se avaliar a contribuição de perfilhos vegetativos e reprodutivos na estrutura do capim-marandu (Urochloa brizantha syn Brachiaria brizantha cv. Marandu) diferido com alturas (15 e 30 cm) e doses de nitrogênio (0, 40, 80 e 120 kg ha-1 de N) variáveis no início do diferimento. O delineamento experimental foi inteiramente casualizado, com três repetições, sendo empregado o sistema fat… Show more

“…This effect can be justified based on the fact that grasses, when submitted to long periods of rest, have a high leaf area index, thus providing greater shading at the base of the canopy. Consequently, the stem elongates and exposes the newer leaves at the top of the pasture (Santos et al, 2018). This concurs with the highest SER at a height of 90 cm (Table 1).…”
