The impact of titanium on plants has been tested for 100 years. Despite this long research tradition, there are few studies dedicated to the optimization of doses and application dates of titanium in cultivation of particular crops. A small-plot experiment involving winter wheat was set up to fill the gap. The aim was to determine the impact of doses and application dates of the biostimulant Mg-Tytanit (MgTi) on the aerial phytomass and underground phytomass formation, quantity and quality of winter wheat yield, and the titanium content in wheat grain and straw. The experiment consisted of 5 treatments: 0 - control without MgTi; 2xTi0.2 - two MgTi applications of a dose of 0.2 dm3 ha-1; 3xTi0.2 - three MgTi applications of a dose of 0.2 dm3 ha-1; 2xTi0.4 - two MgTi applications of a dose of 0.4 dm3 ha-1; 3xTi0.4 - three MgTi applications of a dose of 0.4 dm3 ha-1. The Mg-Tytanit was applied in spring during two or three different growth stages: BBCH 29, BBCH 32-37, BBCH 55-59. The MgTi application in the growth phases BBCH 29 and 32-37, regardless the applied doses, increased the yields of aerial phytomass and underground phytomass. All MgTi applications increased straw yield. The use of Mg-Tytanit in the total doses from 0.6 to 0.8 dm3 ha-1 caused a significant increase in wheat grain yield. The MgTi did not have a significant influence on the majority of qualitative parameters of wheat grain. One tonne of grain and an appropriate quantity of straw needed about 26.2 g of titanium uptake.
