Abstract
The purpose of research – increasing the yield of winter oilseed rape with minimum tillage. Allelopathic activity was determined by germinating seeds in Petri dishes of winter rape seed varieties Dragon in different concentrations present crop residues of winter wheat. In the first series of experiments at a concentration of infusion of 25 to 100% is already on the third day there was a strong (34-43%) inhibition of germination of seeds of winter rape, and on the seventh day of germination decreased by 64-80%. It is very strongly inhibited the development of seedlings of winter rape. In a second series of experiments (concentration present from 5 to 20%) only at concentrations of 5 and 10% showed very little (2-4%) and mild (7-8%) reduction in germination of winter oilseed rape, wherein the 7th day of observation all the seedlings have formed cotyledon leaves of green with long stem 35,3 and 30,4 mm in length spine – 20,3 and 18,1 mm. Increasing the concentration to 15 and 20% led to a decrease in the laboratory germination at 18 and 43%, of which only 84 and 74% of the seedlings have formed a pale yellow color.
