| Abstract:
The results of a research on the water use distribution along the crop season and on the effects of different irrigation regimes on eggplant (cv. Black Beauty), grown in Southern Italy, are reported. In order to calculate the crop coefficients (Kc), the daily maximum evapotranspiration values, evaluated by weighing lysimeter during the growing season, were divided by the corresponding values of class "A" pan evaporation and ETo calculated by the Blaney-Criddle method. During the growing season the root growth and distribution were evaluated on five dates. Along the soil profile the root distribution was measured from 0 to 50 cm depth with the Newman's method. Water regimes affected root growth and distribution along the soil profile during the growing season and gave remarkable yield differences with the best results corresponding to a water restitution of 75% of ETM. | |
