Abstract

Abstract

Standard pan evaporation has been used to estimate evapotranspiration under flooded conditions, but it is difficult to determine crop coefficients, which vary with growth stage and leaf area index. Taro [Colocasia esculanta (L.) Schott], a wetland plant, was used to study the relationships among standard pan evaporation, evapotranspiration, and leaf area index. Lysimeter investigations were conducted for 2 yr (1981–1982) on flooded Pahokee muck (Lithic Medisaprists). Total evapotranspiration was about 1200 mm and ranged from 1.5 to 7.2 mm day−1, with an average of 4 mm day−1. The evapotranspiration/standard pan evaporation ratio was inversely related to leaf area index, whereas in nonflooded crops it is directly related
