Drought stress is one of the most common environmental stress factors responsible to yield loss in several crops worldwide. Successful crop management under drought depends on better agricultural management and understanding of water productivity. Increasing water productivity without causing severe yield reduction has been found successful under limited water supply conditions. Therefore, improving methods and strategies to cope with deleterious effects of drought stress has received considerable attention recently. In this context, an eggplant seedling experiment was conducted in the greenhouse with the application of six different doses of melatonin (0, 5, 25, 50, 100, 150 μM) to investigate response of plants under drought conditions (100 and 60% of water to reach the field capacity). Plant fresh weight was used to determine water use efficiency of the eggplant. We found that water use efficiency decreased by roughly 23% with drought as compared to control. And foliar application of melatonin slightly improved the water use efficiency of the eggplant at the concentrations of 25 μM. The result of this experiment indicates that using melatonin as an ameliorative amendment under drought conditions could be useful to improve the eggplant drought tolerance.
