Résumé
The objective of this research was to make better estimates of crop evapotranspiration (ETc) by improving seasonal crop coefficient (Kc) curves. A review of Kc values for tomato and melon crops showed important differences between the data measured under different climate conditions. The relationship between Kc values and some growth parameters (leaf area index LAI, temperature, and mulching) was investigated using lysimeter-measured ETc data from the Bari University and CNR-Bari experimental station located in Policoro (Southern Italy). The results indicated that the seasonal Kc can be modelled satisfactorily for either crop using a linear relationship between Kc and cumulative growing degree days or a logarithmic relationship between Kc and LAI. The initial growth stage can be neglected under Mediterranean arid and semi-arid conditions. Mulching increases the peak Kc of melon but reduces the length of the growing season.
