Současné trendy a výsledky pěstování řepky olejky (Brassica napus L.)

The first part of this thesis is based on the theory and recorded findings of growing winter oilseed rape. The second part of the thesis describes phenological observations of winter rape from sowing the seeds to the harvest, which were conducted in the company Zemo, spol. s r.o., in the years 2015/2016. During these observations, grower´s inputs were recorded, in which innovative solutions in the cultivation of winter oilseed rape hybrids were used in the above mentioned company. Three land blocks (Greit, Šarcles and Štumpigl) with three winter oilseed rape hybrids (Marathon, Mercedes and Sherpa) were selected and every month the following data were observed: BBCH stage, the number of plants per sq m, plant height, root length and the diameter of the root neck. Furthermore, the average yield of hybrid seeds harvested per hectare was calculated, which was then compared to the company´s average yield of the same varieties, as well as to the company and whole country´s average yields of winter oilsee rape in the years 2014, 2015 and 2016. The data were statistically processed and evaluated graphically
