In this study, field crop experiments were conducted in the Mediterranean region of Turkey and the relationship of the air temperature (TSUM), hours of sunlight (SSUM), the length of the vegetation period (Lv), and yield of three field crops (safflower, cotton, and potato) having different yield compositions (contain by order of lipid, fiber, and carbohydrate) were investigated. The data sets of Lv, TSUM, SSUM, and yield with their descriptive statistics for the three field crops are given as well. It is shown that TSUM and SSUM have significant influence on the duration of the vegetation period in all crops. Yield also had a positive correlation with TSUM and SSUM in safflower and cotton.
