“…1b). Cruz (2010) estimated the optimum temperature for Marandu palisade grass growing in Brazil to be between 27 and 35°C. Values between 26 and 30°C have also being reported as optimum for the growth of other tropical and subtropical pastures: buffel grass ( Cenchrus ciliaris L.), Rhodes grass ( Chloris gayana Kunth), Trichoglume Guinea grass, Makarikariense colored Guinea grass, panic clandestin ( Panicum clandestinum L.), and Texas panicum ( Panicum texanum L.) (Ivory and Whiteman, 1978; Patterson, 1990).…”

“…Studies that used biophysical models (e.g., CROPGRO and GRAZPLAN) have been developed for U. brizantha spp. cultivars under irrigated (Pedreira et al, 2011; Lara et al, 2012) and rainfed (Cruz, 2010) conditions for the southeast of Brazil. The APSIM model (Keating et al, 2003) is an example of such a modeling approach.…”

“…A cultivar Marandu foi plantada nas duas áreas, sendo a semeadura realizada a lanço (10 kg ha -1 ). Trata-se de uma planta perene, cespitosa, muito robusta, com produção de matéria seca, em ambiente amazônico, em torno de 1,6 t ha -1 no período seco e 3,3 t ha -1 no período chuvoso, podendo atingir mais 95 % de cobertura do solo (Oliveira et al, 2007;Cruz, 2010). A pastagem nativa em SN (Trachypogon vestitus) apresenta produção média de 1.000 kg ha -1 de matéria seca e baixas taxas de crescimento e cobertura do solo, quando comparadas com cultivares comercias de B. brizantha (Costa et al, 2012).…”

“…Under these conditions, the constant conservation of soil moisture as a result of reduced solar radiation favors the absorption of water and nutrients controlling the presence of the brachiaria. According to Cruz (2010), among the determinant factors for forage production (temperature, luminosity, water and nutrients) water availability is the most important. Another fact, noted by Corsi and Nascimento Junior (1989), would be the environmental conditions of high evapotranspiration that may be harmful for grazing.…”
