The objective of this study was to understand how the strategy of defoliation prior to deferred grazing modifies the structure of Brachiaria brizantha cv. marandu (marandu grass) at the beginning of deferment. The following three defoliation strategies wer e evaluated: 15/15 cm – canopy height of 15 cm in the three months prior to deferment
30/15 cm – canopy height of 30 cm in the preceding three months and defoliation to 15 cm at the beginning of deferment
45/15 cm – canopy height of 45 cm in the three preceding months and defoliation to 15 cm at the beginning of deferment. A complete randomized design with four replications was used. When compared to the 30/15 and 45/15 cm canopies, the 15/15 cm canopy exhibited a larger number of tillers (P

Objetivou-se compreender como a estratégia de desfolhação prévia ao período de diferimento modifica a estrutura da Brachiaria brizantha cv. Marandu (capim marandu) no início do diferimento. Três estratégias de desfolhação avaliadas foram 15/15 cm: dossel com 15 cm nos três meses antecedentes ao diferimento
45/15 cm: dossel com 45 cm nos três meses prévios e rebaixado para 15 cm no início do diferimento. O delineamento inteiramente casualizado, com quatro repetições foi utilizado. Em comparação aos dosséis com 30/15 cm e 45/15 cm, o dossel com 15/15 cm apresentou maior (P
30/15 cm: dossel com 30 cm nos três meses prévios e rebaixado para 15 cm no início do diferimento
