The experiment was carried out in Barbar locality, Sudan during two successful years (2015 and 2016) in an area of 0.2 ha. The objective of the study was to quantify the effect of different irrigation systems and different water quantities on Eggplant (Solanum melongena) production under dry conditions. The treatments were three irrigation systems (surface drip irrigation, subsurface drip irrigation and furrow) and three amounts of irrigation water: (100%, 75% and 50% of ETc). The parameters measured were yield components and plant yield (ton/ha). Class A Pan was used to estimate the eggplant evapotranspiration. The experiment was organized in spilt plot procedure accordingly complete randomized block design. SAS statistical package was used to achieve the data statistical analysis. The results showed that yield parameters were significantly (P ≤ 0.05) affected by all treatments. Surface drip and subsurface drip irrigation systems gave the highest values of eggplant yield and yield components as compared to furrow irrigation system, which recorded the lowest values of yield parameters. On the other hand, the aforementioned parameters were increased with increasing in the amount of irrigation water. The highest values of all parameters measured were recorded with 100% ETc and the lowest values appeared in 50% ETc. The conclusion of this study is that surface drip and subsurface drip irrigation systems are convenient for eggplant production under dry conditions.
