Capim-marandu e babaçu em sistema silvipastoril

Abstract

O trabalho objetivou avaliar efeito do babaçu (Attalea speciosa Mart.) sobre os aspectos de: produção de sombra, presença de plantas daninhas, área de solo nu, massa e composição química do pasto de capim-marandu (Brachiaria brizantha cv. Marandu) nos períodos de maior e menor disponibilidade de água, mantido sobre pastejo intermitente, com período de descanso de 30 dias no período das águas e 60 dias no período seco, utilizando a técnica de “mob-stocking”. O experimento foi conduzido de setembro de 2010 a setembro de 2011, na Fazenda Santo Antonio em Matinha – MA. A área experimental foi dividida em seis piquetes com as respectivas densidades: 10, 20, 30, 40, 50 e 60 palmeiras por hectare. O delineamento experimental foi formado por parcelas sub-divididas, tendo nas parcelas um fatorial 2 x 6 (dois períodos e seis densidades) e nas sub-parcelas o sombreamento (sombra e sol) com quatro repetições cada. No período das águas o aumento da densidade de palmeiras de babaçu (Attalea speciosa Mart.) em linhas gerais: reduziu à proteína bruta, a porcentagem do solo nu, aumentou a matéria seca da forragem e a umidade do solo. No período seco, o aumento da densidade de palmeiras de babaçu reduziu a proteína bruta e a porcentagem do solo nu. Nas áreas sombreadas o aumento da densidade de palmeiras contribuiu para maiores teores de umidade. O porte elevado das palmeiras de babaçu reduziu o efeito do sombreamento como fator de inibição do desenvolvimento do capim-marandu. A massa seca de capim-marandu foi maior no período das águas e no período seco a massa seca de plantas daninhas, onde o babaçu em sua fase inicial e o capim-duro (Paspalum virgatum) tiveram respectivamente maior participação. O aumento das densidades de palmeiras de babaçu reduziu a massa de plantas invasoras...

The study aimed to evaluate and measure the effect of babassu (Attalea speciosa Mart) in the following aspects of: shade production, weeds, bare soil area, herbage mass, chemical composition of the marandu grass (Brachiaria brizantha cv. Marandu) during periods of greater and lesser availability of water, kept on rotational grazing with rest period of 30 days during the rainy season and 60 days in the dry season, using mob-stocking technique. The experiment was conducted from September, 2010 to September, 2011 in Matinha - MA. The experimental area was splitted into six areas with the following densities: 10, 20, 30, 40, 50 and 60 palms per hectare. The experimental design was split-plot having a 2 x 6 factorial (two seasons and six densities) and the shadowing sub-plot (shadow and sun) with four replications. On the rainy season the density increments of the babassu palms (Attalea speciosa Mart.) in general: reduced the crude protein, bare soil percentage, increased the forage dry matter and the soil humidity. In the dry season, the density increments of the babassu palms reduced the crude protein and the bare soil amount. In the shadowing areas the density increments of the babassu palms contributed to increase the soil humidity. The high size of the babassu palms reduced the effect of shadowing as inhibition factor of development of marandu grass. The marandu grass matter was greater during the rainy season and on the dry season the weeds, where the young Attalea speciosa Mart. and the Paspalum virgatum had greater participation. The density increments of the babassu palms reduced the weeds matte... (Complete abstract click electronic access below)
