Statistical provision of the problem of sunflower production in the Krasnodar region

The statistical analysis of production factors of sunflower cultivation in the agricultural organizations of the Krasnodar region showed that for the studied period there was a growth of yield stability and crop bulk yield against the background of steadying stability of cultivation areas. It was established that the analysis of factors of stability indicators of sunflower cultivation based on the five years’ gliding periods does not allow making the precise estimation of the outlined tendency in stability indicators. It is possible to avoid this problem by using the statistical method based on determination of variability tendencies by means of analytical straight aligning of measures of mean square deviations that had already been leveled. Consequently it was determined that stability growth of bulk yield against the background of steadying of sunflower oilseed cultivation areas in the Krasnodar region suggests the positive tendencies in the development of oil branch of industry and the basis of these tendencies is the production intensification.
