Sažetak
Optimal fertilization of oilseed rape is a basic precondition for achieving high and stabile crops.
For the use of physiologically right and economically justified fertilization of oilseed rape, it is necessary to know both the dynamics of accumulation of dry matter and the dynamics of absorption of individual nutrients during vegetation, as well as the effects of certain nutrients on quantity and quality of crops. During defining of quantities and relations, as well as the time and manner of applying as the main so the micro fertilizers, the basis must be soil analysis and dynamics of absorption of the very same, that is, plant’s needs for certain nutrients during vegetation. When fertilizing oilseed rape, one half of complex NPK mineral fertilizers should be used in basic soil cultivation, and the other half in pre-sowing soil preparation. The total amount of nitrogen used in autumn, shouldn’t be more than 50 to 60 kilos per acre. Most of the nitrogen is used in two nutrition reinforcements, just before the beginning of vegetation in spring and at the beginning of the stem upgrowth.
