The Qassim region is considered one of the agricultural areas in Saudi Arabia which is characterized by abundant groundwater and arable land, Cultivation of date palms with high date productivity. With regard to the history of date palm trees in Saudi Arabia, it is noted that it has achieved a global position in the field of date palm cultivation and date production, in terms of palm growing, number and quantity of production. It is one of the largest palm branches in the world, producing annually 1,122 million tons of more than 25 million Palm.

Preliminary data sources were obtained through the use of a questionnaire Survey for a random sample (30 farms) and interviews of date farmers in the region, as well as secondary data sources represented in books, references, annual reports and the International Information Network. The study found that a large number of palm tree farms were destroyed and the production of tuna was reduced. Thus, the quantity of dates produced decreased.
