Irrigação de pastagem: atualidade e recomendações para uso e manejo

Abstract: RESUMO -Nos últimos anos tem sido grande o interesse pela irrigação de pastagens e pelos temas engenharia, custo de equipamento, custo de manutenção de energia elétrica, demanda de água e de energia elétrica, manejo da irrigação e fertirrigação. Tal interesse tem aumentado a demanda por informações e recomendações práticas que ajudem a esclarecer os aspectos importantes como a escolha do sistema de irrigação, a evapotranspiração potencial (ETo), o coeficiente da cultura (Kc); a evapotranspiração da cultura (ET… Show more

“…However, for the other cuts, with the increase in mean air temperature and incident radiation and the development of the pastures, the Kc value was higher. The Kc values for Mombaça and Piatã grasses in the present study are above the single, constant value of 0.8, recommended by Alencar et al (2009b). Therefore, with the lack of information for irrigation management in pastures, recommendations of single Kc values, close to 1.0, promoted the higher pasture yields compared with the value suggested by Alencar et al (2009b).…”

“…Despite their contrasting morphological characteristics, both species were included in this study for meeting two premises: Xaraes grass had been recently launched by EMBRAPA, in 2003 (Valle et al, 2004) and stood out in an assay under irrigation (Alencar et al, 2009a) involving tropical grasses; tifton 85 grass was tested in several experiments under irrigation (Marcelino et al, 2003;Aguiar et al, 2006;Balieiro Neto et al, 2007) and could serve as a reference species due to the greater number of studies.…”

“…Dentre as possibilidades para a melhoria do manejo de pastagem na pecuária brasileira, a irrigação constitui uma tecnologia que proporciona incrementos e estabilização de produtividade, uma vez que pode suprir a demanda hídrica durante a época seca do ano e suplementá-la na época chuvosa (ALENCAR et al, 2009a;LOPES et al, 2014).…”
