Summary The responses of two egg-plant varieties to irrigation rhythm and water supply based on daily potential evapotranspiration were performed on St-Paul silt loam. Results showed that a shorter irrigation rhythm gives the best production in terms of fruit yield (Table 1). Daily irrigation gives a leaf blade with a lower specific weight than the bi-weekly irrigation rhythm during the whole sampling period (Fig. 1). When we compared 4 quantities of water representing 40 to 100% of the potential evapotranspiration, the best results in terms of fruit yield were obtained with the irrigation giving 80% of the potential evapotranspiration (Table 2). But there is no significant difference between the specific leaf weights (Fig. 2). When we observed the varietal behaviour we found that the cultivar ‘Violette de Barbentane’ gives a production 20% higher than that of ‘Ronde de Valence’. But the water potential and transpiration resistance of leaves are not very different for the two varieties (Figs. 5 and 6).
