Abstract

In this study, the yield and possible salt accumulation around the root area of eggplant was investigated. Seven irrigation treatments were tested including a controlling irrigation (FULL). Two of these irrigation treatments had 25% and 50% less water accordingly than the treatment of FULL and water was conventionally applied to both sides of the plant roots (CDI25 and CDI50). The other two deficit irrigation treatments had 25% and 50% less water accordingly than the treatment of FULL and water was applied only one side of the roots and the other halves were left relatively dry in each irrigation. This case was replaced alternatively for every irrigation (APRD25 and APRD50). The last two deficit irrigation treatments had also 25% and 50% less water accordingly than the treatment of FULL, however throughout the season water was applied only one side of the roots and the other halves were left relatively dry in each irrigation in fixed irrigations (FPRD25 and FPRD50). The differences between the yields of the eggplant under different irrigation treatments were statically important (p < 0.01). The range of yields depending on irrigation treatments were between 23.37 t ha(-1) and 83.10 t ha(-1). The highest salt accumulation was recorded in treatment FPRD25 for the root area and treatment CDI50 for along the rows of plants. When compared with the values of the beginning of the season; the salinity was multiplied by 3.2 for the root area of treatment FPRD25 at the end of the season. In a similar way, the salinity was multiplied by 7.1 at the end of the season for treatment CDI50 along the rows of plants when compared with the beginning of the season.
