Various methods can be used to determine timing of irrigation. In recent years, a significant portion of the methods developed for this purpose uses indicators against plant monitoring. Leaf water potential measurements are also becoming one of the widely used indicators. In this study, the effects of different irrigation water salinity levels on leaf water potentials as a physiological characteristic of tomato plant grown under partial root drying irrigation technique were investigated. In the study, irrigations were realized as a weekly basis until the mid-season and twice a week after the mid-season to harvest. Throughout the study period, a vast number of observations and measurements were performed. In this article, however, it is aimed to evaluate the possible changes in leaf water potential due to different salinity levels of irrigation water. Leaf water potential can be measured before and after watering and in the mid-day. In addition, it can be measured before sun rises and in the range of certain period in a day (i.e. 2 hours). As a result of this research, it was determined that varying levels of irrigation water salinity and irrigation practices affect leaf water potential of tomato plants at different levels.
