The effect of grain dressing with humic substances contained in the preparation Humistar (Humifirst) on the germination energy and capacity, as well the dynamics of the initial growth and development of wheat and barley were assessed in laboratory study. It was showed that the application of the preparation did not affect the proportion of kernals germinating normally in the laboratory assessment of germination energy and capacity of the tested cereal species. Dressing barley grain with Humistar stimulated elongation and growth in the germ mass as early as in the first week of germination, and of the root mass in the second week. A positive effect of the preparation on the growth of wheat seedling fresh mass was observed after 14 and 21 days of development.
