Responses of eggplant crop to 3 irrigation rhythms based on the daily potential evapotranspiration were investigated. Results showed that the shorter the rhythm (5 times/wk) the better the plant growth expressed in terms of plant length and/or yield shown as fruit number or fruit fresh weight. The twice per week rhythm gave the medium; the 10 days rhythm gave the least plant growth and yield. Also the frequent rhythm (5 times/wk) gave an earlier crop presented as flower setting. The 3 rhythms did not show an effect on crop quality expressed as mineral content of leaf blades, petioles or fruits. Leaf blades usually have higher mineral content than the fruits, especially with the micro elements.
