Abstract
This paper examines the interdependency between the movements of the level of market (purchase) prices and sowed areas under sunflower, soya, and oilseed rape, i.e. between the relative prices of these oil crops and predominant crop-husbandry products (wheat and/or corn), on the one hand, and the areas to be allocated for oil crops cultures. The models of the regression of the scope of sowed areas and purchase prices of oil crops, i.e. the interdependency of these phenomena, are determined by means of reliable statistical methods (the standard error of regression, the coefficient of the trend variation and the determination coefficient). At the same time, the testing of the series has been carried out by means of the mathematical models of functions, whereas the significance of the generated regression dependencies has been estimated by means of the t-test.
