This research was carried out in 2010-2011 growing seasons at Tarsus in Turkey. The experimental treatments; Drip treatments consist of full irrigation (DI <sub>100 </sub>), deficit irrigation DI <sub>75 </sub>, DI <sub>50 </sub>, DI <sub>PRD50 </sub>, and DI <sub>FPRD50 </sub> Alternative partial root drying (DI <sub>PRD50 </sub>) and fixed partial root drying (DI <sub>FPRD50 </sub>) received 50% of DI <sub>100 </sub>. Irrigation was applied when 25% and 40% of the available water in the 60 cm soil profile were consumed in DI <sub>100 </sub> and FI <sub>100 </sub> treatments in drip and furrow systems, respectively and soil water replenished to field capacity in DI <sub>100 </sub> and FI <sub>100 </sub> treatments. In furrow irrigation, treatments consist of full irrigation (FI <sub>100 </sub>), alternative furrow (FI <sub>A50 </sub>) and PRD furrow (FI <sub>PRD50 </sub>). FI <sub>A50 </sub>and FI <sub>PRD50 </sub> received 50% of water applied to FI <sub>100 </sub>. In FI <sub>A50 </sub> the same furrows were irrigated while FI <sub>PRD50 </sub> irrigated alternately. The highest yields in drip and furrow systems were obtained from the DI <sub>100 </sub> and FI <sub>100 </sub> treatments, respectively. In generally, DI <sub>FPRD50 </sub> treatment was the highest a* value in drip irrigation system which means that fruits had more red color. On the other hand, b* values (it represents yellow color because of positive values) decreased following the first picking. In generally, the color parameters (a* and b*) of furrow irrigation treatments in the different picking times was not statistically significant. Total carotenoid rates increased with following picking time both drip and furrow irrigation systems and it is lower value under drip system than in the furrow system. Finally, results indicate that in drip irrigation DI <sub>100 </sub> treatment; and in furrow irrigation, FI <sub>100 </sub> treatment was recommended. Under water scarcity conditions, DI <sub>75 </sub> and FI <sub>PRD50 </sub> treatments can be recommended.  </span> <br> </p>}, number={1}, publisher={ISRES Publishing}
