Abstract
The article considers impacts of changes in structure of crop area on yield change in the context of fruitful and unfruitful years, difference between these indices is analyzed; conversion of Durbin-Watts criterion for comparison of their values with correlation coefficient of the first order in relation to their time-to-time variability at characteristic of interrelation between chain absolute yield increment is offered; variant of expansion of correlation coefficient, characterizing interrelations between chain absolute yield increment between regions, by separate components related to trend and weather fluctuations, is offered; simultaneity in yield fluctuations in relation to weather conditions and dynamics of the most unfruitful years are analyzed; relationship between yield and net cost is examined.
