Özet

This study was conducted ın Bandırma (Balıkesir, Turkey) during the growing season of the plant in 2017 and2018 to determine the effect of four levels of irrigation water and three kinds of fertilizer on yield and water useof field-grown eggplant (solanum melongena). Treatments included four irrigation regimes, which were 100%($I_{100}$, control), 80% ($I_{80}$), 60% ($I_{60}$), and 40% ($I_{40}$) of evaporation from Class A Pan and three different fertilizers,which were chemical fertilizer CHF; N, P, K (20-20-20+15 SO3) added as 40 kg $da^{-1}$ organic fertilizer (OF)added as 2000 kg $da^{-1}$ and developed organic fertilizer (DOF) added as 2000 kg $da^{-1}$. Total irrigation water of305 mm and 360 mm were applied to I100 irrigation treatment, in which water use was determined as 447 mmand 436 mm, respectively. In both experiment years, the effect of irrigation level on fruit yield was found to besignificant statistically (p<0.05) but the effect of fertilizers treatments and irrigation x fertilizer interaction wasinsignificant (p>0.05). The highest yield with 3681and 4515 kg $da^{-1}$ was harvested from I100 irrigation treatment,and the lowest yield with 3021 and 2792 kg $da^{-1}$ from I40 irrigation treatment, respectively. As for fertilizer, thehighest yield with 3462 and 3878 kg $da^{-1}$ was harvested from DOF, while the lowest yield with 3258 and 3629kg da-1 from OF, respectively. Water use efficiency (WUE) ranged from 8.26 to 12.54 kg $mm^{-1}$ and irrigationwater use efficiency (IWUE) from 11.9 to 25.68 kg mm-1 in the experimental years. Thus, in irrigationprogramming, the Kcp3: 0.80 plant-pan coefficient and in fertilizer application, DOF is recommended for fieldgrown eggplant.
