Resumo: The evapotranspiration (ET) of corn crop (Zea mays L.) (Pioneer X-307 hibrid) calculated during four years (1976-1980), was related with solar radiation (Rs) and net radiation (Rn) in the different stages and in the cycle of the crop. This trial was conducted in Taquari, Rio Grande do Sul, 29 °48'15" south latitude and 76 m of altitude. Both relations presented the same tendency. They were lower during the early cycle of the crop, increasing progressively with the development of the plants, reaching maximum values during tasseling and silking period. During this period, the relation ET/Rs varied from 0.62 to 0.79 during the four years (with mean of 0.70) while the relation ET/Rn varied from 0.83 to 1.07 (with mean of 0.94). After flowering, there was a decrease in the values of the relations until physiological maturation of crop. The relations ET/Rs and ET/Rn during the cycle of development of the crop, obtained mean values of 0.51 and 0.69, respectively.

Ambas as relações apresentaram a mesma tendência. Foram menores durante o inicio do ciclo de desenvolvimento da cultura, aumentando progressivamente à medida que as plantas se desenvolviam, atingindo valores máximos durante o subperíodo pendoamento-espigamento. Durante este subperíodo, a relação ET/Rs variou de 0,62 a 0,79 durante os quatro anos (com uma média de 0,70), enquanto que a relação ET/Rn variou de 0,83 a 1,07 (com uma média de 0,94). Após o florescimento, houve um decréscimo nos valores das relações até a maturação fisiológica da cultura. As relações ET/Rs e ET/Rn, durante o ciclo de desenvolvimento da cultura, tiveram valores médios de 0,51 e 0,69, respectivamente.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMatzenauer, RonaldoWestphalen, Sérgio LuisBergamaschi, Homero2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15987Pesquisa Agropecuaria Brasileira; v.17, n.7, jul. 1982; 1051-1056Pesquisa Agropecuária Brasileira; v.17, n.7, jul. 1982; 1051-10561678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15987/10113info:eu-repo/semantics/openAccess2014-04-16T16:21:37Zoai:ojs.seer.sct.embrapa.br:article/15987Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T16:21:37Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
