The ways to improve the vitality of sorghum seed after treatment with Lexin and M-Sunagreen were tested in laboratory conditions. These methods of seed stimulation were also tested in field conditions. All experiments were carried out in 2011–2013. Positive results after using the presented formulations for testing of germination were observed not only in laboratory conditions but also in field experiments. Seeds stimulated by Lexin reached statistically higher germination (95%) compared to control (91.5%) with the shortest medium time of germination (3.5 days) versus control seeds (4.3 days). Higher, faster and smoother germination of stimulated seeds resulted in higher average number of plants per m2 (about 2.1 plants/1 m2 in Lexin compared to control seeds) and thereby contributed to higher average yields up to two tons of dry matter per hectare.Keywords:
