In a phase of the beginning of blossoming loss of a large amount of rainfall was observed and temperature was above average long-term data (18,5 ° C on average in a decade). This phase is critical, and sufficient humidity defines productivity of tubers. But in the next decades weather conditions developed not absolutely favorably.

Similar dependence remained and on the second background, though increases on collecting starch to control below, than on the first background. Higher collecting starch is received in option with mineral and organo-mineral systems of fertilizers, respectively, 25,23 and 24,91 c/hectare, and lower - on organic system of fertilizers - 24,05 c/hectare.
