Production function and factor analysis were chosen from the wide range of statistical methods to analyse data obtained in two different experiments. The production function was used to evaluate the optimal level of factors which influence sugar beet production (maximum yield per 1 ha). The calculation was based on optimal doses of nitrogen and potassium from the economical point of view. The factor analysis enabled to define which factors favourably or unfavourably influenced the sugar beet production. Thirteen variables were chosen to calculate the factor analysis model. As shown by our results, sugar beet yields were favourably influenced by the doses of NPK and manure, and unfavourably affected by the calendar week of sowing.
