This research revealed the changes in wheat yield, area planted and loans given to wheat farmers with time, in Tabouk region in particular and the Kingdom in general in the period extending from 1980 to 1988. The data is intended to assess the possibility expansion and production of wheat in Tabouk area. Data were collected from the Ministry of Agriculture and Water, and from Saudi Arabia Agricultural Bank. The analysis included both cartographic and quantitative analytical systems. The results showed positive and linear regression relationships between time and wheat yield, cultivated area in both Tabouk area and the Kingdom. A curvilinear relationship was found between loans and years of production in the Kingdom. This relation was linear in Tabouk region. The results also showed a very strong significant relationship between the progress in crop yield and the area planted and loans, and also between the area and loans. This indicated that wheat yields at Tabouk region were higher compared to those obtained in other parts of the Kingdom.
