Growth of tropical forage grasses and legumes under shade

Growth of tropical forage grasses and legumes under shade

Show other versions (1)

The objective of this work was to evaluate the effect of levels of artificial shade (0%, 30%, 50% and 70%) on dry matter accumulation rates of four tropical forage grasses (Brachiaria brizantha cv. Marandu, B. humidicola cv. Quicuio-da-amazônia, Panicum maximum cv. Massai and Paspalum notatum cv. Pensacola) and three forage legumes (Arachis pintoi cv. Belmonte, A. pintoi BRA-031143 and Pueraria phaseoloides) in Rio Branco, Acre, Brazil. To measure dry matter accumulation rates, nine cuts were performed between November 1999 and April 2001. The grasses Marandu and Massai had the best performance, with good shade tolerance and productivity, and were good options for silvopastoral systems in areas with well-drained soils. The quicuio-da-amazônia grass showed lower shade tolerance, and was recommended only for low tree density silvopastoral systems in areas with good rainfall distribution or with poorly drained soils. The Pensacola grass showed high shade tolerance but it is not recommended for silvopastoral systems in the Western Amazon region because of its low yield capacity. Arachis pintoi cv. Belmonte showed higher yield capacity and shade tolerance than the other legumes.

O objetivo deste trabalho foi avaliar o efeito de níveis de sombreamento artificial (0%, 30%, 50% e 70%) nas taxas de acúmulo de matéria seca de quatro gramíneas (Brachiaria brizantha cv. Marandu, B. humidicola cv. Quicuio-da-amazônia, Panicum maximum cv. Massai e Paspalum notatum cv. Pensacola) e três leguminosas forrageiras (Arachis pintoi cv. Belmonte, A. pintoi BRA-031143 e Pueraria phaseoloides), em Rio Branco, Acre. No período de novembro de 1999 a abril de 2001, foram realizados nove cortes para medição das taxas de acúmulo de matéria seca. Os capins marandu e massai tiveram o melhor desempenho entre as gramíneas, aliando boa tolerância ao sombreamento e alta capacidade produtiva, constituindo opções importantes na composição de sistemas silvipastoris em áreas com solos bem drenados. O quicuio-da-amazônia apresentou menor tolerância ao sombreamento, podendo ser usado em sistemas silvipastoris com baixa densidade arbórea, em áreas com chuvas bem distribuídas ou com solos mal drenados. O capim-pensacola apresentou alta tolerância ao sombreamento, mas baixa capacidade produtiva, não sendo recomendado para a região. O Arachis pintoi cv. Belmonte demonstrou maior capacidade produtiva e tolerância ao sombreamento que as demais leguminosas.
