Conteúdo: | This paper reports the results of a two-year field study at Logan, Utah which was one of series of similar experiments carried out at Ft. Colins, Colorado, Davis, California and Yuma, Arizona. A range of water application rates were imposed using the line-source system (Hanks et al., 1976) and in some treatments water was withheld during certain growth stages. Salinity variables were imposed by presalinization before planting and by the use of saline irrigation water. Regardles of irrigation or salinity regime, corn grain and total dry matter production were linearly related to evapotranspiration, which was measured as the sum of irrigation, rainfall and soil water depletion minus drainage. Presalinization of the soil decreased yields in proportion to the sa  linity imposed, the decrease being associated with reductions in evapotranspiration caused by reduced soil water depletion as compared to   the nonsalinized treatments.
