Résumé
The aim of this study was to determine the relationship between the water and the yield in the eggplant using drip irrigation method. This study was conducted using randomized block design with three replicates. In the Class A evaporation pan, the water levels were examined for providing %50, %75, %100, %125 and %150 of four-days total evaporation amount, and five different pan coefficient (kcp1=0.50, kcp2=0.75, kcp3=1.00, kcp4=1.25 and kcp5=1.50) were used. Results showed that the increase in the irrigation water amount caused a linear relationship in the studied parameters. In the treatment of 50%, a water stress and lower yield occurred in the plants due to the water levels. However, the plants provided higher yields at the treatment of %150. In this study, data of ten different times of harvesting were used. The highest yield (8 311 kg/da) and the lowest yield (3 325 kg/da) were obtained at the treatment of %150 and 50%, respectively. These findings and results demonstrated that the water was a statistically significant (p<0.01) factor on the yield and yield components. This study also showed that the production of eggplant (Solanum melongena L.) required high amount of water for the optimum yield values at the semi-arid climate conditions ; however, the treatments excessively irrigated resulted in the damage to the root of the plant.
