The study on the effects of different irrigation practices under drip irrigation method on eggplant water use, yield and vegetative
parameters was carried out under Tekirdag conditions in 2015 and 2016. Four different irrigation water amounts with 5 days
interval applied based on a ratio of Class A pan evaporation as 50, 75, 100 and 125 % were created in the research. In the
first year of the study all treatments with irrigation water application 20 times between 283.0 and 693.0 mm with irrigation
application, 19 times of 293.0 and 693.0 mm of irrigation water in the second year and was applied. As a result of this
study, the seasonal evapotranspiration in the treatments during the measurement period varied from 466.2 and 837.0 mm in
2015 and from 411.7 and 797.1 mm in 2016 depend on irrigation water applied. The daily crop evapotranspiration varied
between 1.6 and 9.5 mm/day in 2015 and between 3.0 and 9.7 mm/day in 2016. Total marketable yield values obtained from
the experiment subjects ranged between 33.4 and 47.6 t ha-1 in the first year and 21.80 to 31.90 t ha-1 in the second year.
Considering the statistical analyses on yield and yield component values, no significant differences were obtained in both
years of the experiment. Irrigation water use efficiency (IWUE) values ranged from 6.86 to 11.80 kg m-3 in the first year of
the experiment and from 4.49 to 7.44 kg m-3 in the second year of the experiment. Water use efficiency (WUE) values were
between 5.68 and 7.16 kg m-3 in the first year of the experiment and 3.83 to 5.30 kg m-3 in the second year of the experiment.
In the statistical analyses among the efficiency values, 50% of the evaporation values measured from the class A evaporation
pan were suggested.
