Results of researches about establishment of root system formation peculiarities of eight maize hybrids on typical black soil with plant density 60 and 90 thousand pieces per hectare and on background different fertilizing rates are presented.

It is proved that the calculation of the need of plants in the elements of nutrition to form a certain level of productivity should take into account not the "horizontal plane" and "volume of soil", where the formation of the root syste
