Comparação de três métodos de estimativa da evapotranspiração de referência para a região de Araraquara - SP

Abstract: RESUMO: Uma forma de verificar a eficiência de métodos de estimativa da evapotranspiração de referência (ETo) é a comparação com o método-padrão. Este trabalho tem por finalidade comparar três métodos de estimativa da ETo: Radiação Solar (RS), Makkink (MAK) e Tanque Classe A (TCA) em relação ao método de Penman-Monteith (PM), em dois períodos distintos das fases de desenvolvimento da cultura de citros, com dados médios quinzenais para os períodos invernoprimavera e verão-outono. A pesquisa foi desenvolvida em … Show more

“…In the evaluation of seven daily estimation methods of ETo for a semi-arid region in Spain, province of Albacete, LÓPEZ-URREA et al, (2006) observed that method RS overestimated ETo obtained by method of PM in 5% when local conditions were of aridity. For the region of Araraquara -SP, VESCOVE & TURCO (2005), comparing estimation methods of ETo , observed that method, RS overestimated ETo for the period summer-autumn more substantially than for winter-spring.…”

“…Similar results found by PILAU et al (2012), in Frederico Westphalen and Palmeira das Missões in Rio Grande do Sul, where the method MK underestimated ETo in relation to PM used as standard in most of the months of the year. For the region of Araraquara -SP, VESCOVE & TURCO (2005), comparing estimation methods of ETo , observed that method Makkink underestimated ETo in relation to PM during winter-spring, more substantially than in the period summer-autumn. In climate conditions of semi-arid Northeast, CAVALCANTE JÚNIOR et al (2011), when evaluating estimation methods of ETo in relation to PM, observed that method Makkink underestimated ETo in humid and dry months, with a more severe underestimation in dry season.…”

“…However, simpler methods should be calibrated to specific locations in order to obtain more reliable data (Mohawesh, 2010). One way to define the reliability of the reference evapotranspiration estimated by simplified methods is to determine the degree of approximation to the value estimated by the Penman Monteith method (Vescove and Turco, 2005).…”

“…Os ventos e as altas temperaturas são os maiores agentes de desidratação, porque intensificam a evapotranspiração, agravando, desta maneira, os efeitos da seca (VESCOVE; TURCO, 2005). As longas estiagens diminuem mais a produtividade das lavouras não-irrigadas desta espécie, comparadas com cultivares de café arábica .…”
