Date palm (Phoenix dactylifera L.) is one of the most important plant growing in arid and semi-arid regions, where it has a social, cultural, economic and nutritious importance. Although date palm can be ranked as the highest salt tolerance plant among fruit crop, extreme salinity can negatively affect its growth, yield and fruit quality. Inadequate annual rainfall of arid regions has stressed and rapidly decreased date palm plantation due to salinity and drought. In this study unmanned aerial vehicles (UAV) was used as a remote sensing platform for the first time in the country to analyze and assess the effect of salinity on date palm using true color UAV aerial images. Eight sites with different salinity levels of irrigation water have been covered. Five random soil samples and irrigation water samples of each site were collected and chemically analyzed for ground-truth. The ENvironment for Visualizing Images (ENVI) and MATLAB softwares were used for pre-processing, processing, and analysis of the UAV aerial images. Through the use of UAV/Drones and true color aerial images, the successful results of this study can open a state of the art solution in assessing and managing one of the most sever environmental problem affecting the arid- regions namely soil/water salinity which is the number one cause of land degradation in this region.
