Popis: This study was conducted in 2016 and 2017, where the effects of different irrigation levels on the water use characteristics and yield parameters of capia pepper were investigated in Tekirdag conditions. The study was carried out by applying four different irrigation levels calculated from the evaporation value (50%, 75%, 100%, and 125%) measured from the Class A evaporation pan in the 3-day irrigation period. In the first year of the research, all treatments were between 351.9 and 857.1 mm and irrigation water was applied 33 times. In the second year of the experiment, irrigation was applied 34 times and the amount of irrigation water applied was between 308.5 and 748.8 mm. As a result of the research, the evapotranspiration amount measured during the plant growing season in treatments were measured between 457 and 935.5 mm in 2016 and between 469 and 889 mm in 2017. When the yield values obtained were examined, the yield values increased with the increase in the amount of irrigation water. In particular, I1 and I2 have come to the forefront as a result of statistical analysis performed at yield values (38.42 t ha-1 and 34.95 t ha-1 respectively). While no difference was observed in terms of fruit width, the values ranged between 4,89 cm and 4,38 cm. According to the fruit length data, differences were determined between the years and 2017 was included in the highest statistics group. According to variance analysis of fruit length values, there was no difference between irrigation treatments and the measurement results were determined to vary between 13.40 cm and 14.46 cm. When the irrigation water use efficiency (IWUE) values were examined, significant differences were detected both between the years and between irrigation treatments and it was seen that the I4 treatment came to the fore. IWUE values were obtained as 4.84 (I1), 5.47 (I2), 5.27 (I3), 6.19 (I4) kg m-3, according to irrigation treatments. When the water use efficiency (WUE) values were examined in the experiment, it was determined that the values ranged between 4.16 and 4.56 kg m-3 and were not statistically significant. © 2020 Namik Kemal University - Agricultural Faculty.
