Abstract: Resumo -O objetivo deste trabalho foi avaliar metas de manejo para capim-marandu (Urochloa brizantha cv. Marandu) submetido a pastejo rotativo e a doses de nitrogênio, de janeiro de 2009 a abril de 2010. Os tratamentos consistiram da combinação de duas frequências de pastejo (altura pré-pastejo de 25 e 35 cm) e de duas doses de fertilizante nitrogenado (50 e 200 kg ha -1 por ano) em delineamento de blocos ao acaso com arranjo fatorial 2x2 e quatro repetições. A altura de pós-pastejo estipulada foi de 15 cm. Ma… Show more

“…Giacomini et al (2009) proposed that canopy heights under 95% light were more suitable for use when marandu palisade grass is close to 25 cm; however, in this study, the post-grazing heights in use ranged from 10 to 15 cm. Likewise, Gimenes et al (2011) studied pre-grazing heights of 25 and 35 cm and nitrogen doses of 50 and 200 kg/ha/year in marandu palisade grass, and they concluded that ideal management would take place at pre-grazing heights of 25 cm and 15 cm residue. However, in this study, the occupation period of the paddocks varied, reaching up to 11 days in the spring/ summer, to ensure the recommended post-grazing height.…”

“…Em estudo com capim marandu, CRuz et al (2011) relataram valor de temperatura base inferior de 17,2ºC, que pode ser interpretada como a temperatura abaixo da qual há limitação do acúmulo de matéria seca de uma espécie, de forma que este se torne nulo ou desprezível (SEntElhaS et al, 1994). Esses fatores, certamente, causaram restrição ao crescimento de folhas e colmo do capim marandu, pois o crescimento vegetal, embora determinado geneticamente, é bastante influenciado por variáveis do ambiente, como temperatura (MaRtuSCEllo et al, 2005), disponibilidade hídrica ; CaEtano e DiaS-Filho, 2008) e de nutrientes (FagunDES et al, 2006;Silva et al, 2009).…”

“…There is the need to apply fertilizers to replace nitrogen in order to maintain or increase production in tamed pastures exclusively with grasses (Mesquita et al, 2010;Da Silva et al, 2010;Gimenes et al, 2011). This is due to the fact that nitrogen is part of several organic composts, amino acids and nucleic acides, and is necessary in higher quantities than any other nutrient by the plabts (Epstein and Bloom, 2006).…”
