Uso da função normal e triangular para simulação do déficit de evapotranspiração.

Abstract

The objective of this research was to compare the simulated evapotranspiration deficit values by normal and triangular functions, in maize crop, for periods of 7, 15 and 30 days without rain, in Piracicaba region, on march and july. The differences on simulated evapotranspiration deficits by two functions, although significants, was small, with averages less than 10% on march and 5% on july.
