Morfogênese e acúmulo de forragem em pastagem de Cynodon dactylon cv. coastcross em diferentes estações de crescimento

Abstract: O experimento foi realizado para se estimar as características morfogênicas e estruturais e a taxa de acúmulo de matéria seca (MS) de lâminas foliares em uma pastagem de Cynodon dactylon cv. coastcross, manejada em sistema de lotação rotacionada com vacas em lactação. As avaliações foram realizadas na primavera (outubro-novembro), no verão (fevereiro-março) e no outono (maio-junho). O estudo foi conduzido em delineamento de casualização completa, com seis repetições. Durante o período de descanso do piquete, o… Show more

“…Likewise, Hack et al (2007) compared Mombasa-grass swards under an intermittent stocking regime managed with two different pre-grazing heights (140 and 90 cm) and two post-grazing heights (0 and 50 cm), showing that the lower pre-grazing height positively influenced canopy characteristics and cow milk production. The consistent pre-grazing height results measured for Aruana Guineagrass suggest a promising use for pre-grazing canopy height as a practical, simple and reliable guide exhibiting remarkable uniformity and consistency regardless of the time of the year, postgrazing height and plant phenological state (Sbrissia & Da Silva, 2001;Vilela et al, 2005;Pereira et al, 2010). However, it should be stressed that height determination must be associated with the physiological and cophysiological parameters of swards to be useful as a management tool.…”

“…For Cynodon dactylon var. Coastcross, Vilela et al (2005) observed that the average time for new leaf appearance was 3.7 days in the summer. Even native species with lower phyllochron, averaging 6.7 days, A. lateralis (166.7 degree days), A. affinis (133.3 degree days), P. notatum (135.1 degree days) and P. plicatulum (172.4 degree days) required more days for appearance of a new leaf, when compared with Coastcross.…”

“…De modo geral, as forrageiras do gênero Cynodon, como o capim-coastcross, possuem características produtivas e nutricionais que permitem elevada produtividade por animal e por área nos trópicos (Vilela et al, 2005), porém o padrão de resposta dessas gramíneas depende das condições de manejo a que são submetidas. Nesse sentido, a adubação nitrogenada e o intervalo de corte, que define a idade de rebrotação da planta, destacam-se como estratégias que modificam a produção e o valor nutritivo do pasto.…”
