In order to obtain the information about changes of titanium contents in the phytomass during the growing season of winter oilseed rape and about the titanium contents drawn by the rape yield during two farming years the small plot field trial was established. In the trial the fertilizer Mg-Titanit (MgTi) containing 8.5 g of titanium in 1 liter was used. The experiment consisted of 5 treatments. 0 – control treatment without MgTi fertilizer; 2xTi0.2 – two applications of MgTi in the dose of 0.2 l/ha; 3xTi0.2 – three applications of MgTi in the dose of 0.2 l/ha; 2xTi0.4 – two applications of MgTi in the dose of 0.4 l/ha; 3xTi0.4 – three applications of MgTi in the dose of 0.4 l/ha. The fertilizer was applied in spring during two, or three different growth stages: BBCH 50, BBCH 59, BBCH 66. The first plant sampling was carried out shortly before the first application of fertilizer (BBCH 50). The second, third and fourth sampling was taken 2–3 weeks after the application of Mg-Titanitu (BBCH 59, BBCH 66, BBCH 71). The obtained results showed that the titanium content in the phytomass of rape was falling during the monitored period. The titanium content in the rape aboveground phytomass varied in the interval from 16.81 to 67.6 mg/kg and in the root in the interval from 56.6 to 258.81 mg/kg. The titanium application on plant leaves in the quantities from 3.4 to 10.2 g per hectare of soil did not have the unambiguous impact on the titanium content in the rape phytomass. In the yield of one tonne of seed and appropriate quantity of rape straw on average 20 grams of titanium was taken in.
