The aim of the study was to determine the influence of herbicide Granstar 75 DF applied in three doses and its mixtures with urea in three concentration on the elements of yield components and yielding of winter wheat. The winter wheat yield was mainly determined by the weight of 1000 grains, then the ear stand, and least of all, by the number of grains per ear. The protection of winter wheat by herbicide Granstar 75 DF, applied in doses: 18 and 24 g per ha and leaf-feeding with urea of concentrations: 18 and 24 percent had a significantly positive effect on yielding
