英语. In course of the research there were studied the optimum seeding rate, dose and timing of mineral fertilizers and biologically active substances to obtain a stable seed production of slough grass (Beckmannia erucaeformis). The research was realized in the conditions of the Republic of Belarus in 2011-2013 on the Vitebsk Experimental Station for Land Reclamation (Belarus). As a result of realized research there were revealed the new experimental data, statistical dependences, influence of elements of technology (norms of seeding of seeds, doses and terms of introduction of mineral fertilizers and biologically active agents) on formation of seed efficiency of slough grass which would make it possible to receive quality competitive production at productivity of seeds of 3.0—3.5 с/ha. In the fertilizer system of slough grass the most effective was spring application of nitrogen at a dose (N35) on the background P50K90 and processing of seed crops by biologically active substances Ecosil 5% v.e and gidrogumat 10% pd in rates of 0.1 l/ha at tillering stage of culture, as well as fractional application of nitrogen N20 and N20 in the spring after the harvest seeds on background P50K90. These variants of fertilizer provided a significant increase in seed production to the level of slough grass 3.66-3.86 c/ha at seed rate of 10 kg/ha, at 14 kg/ha, respectively – 3.19-3.54 and 6 kg/ha – 2.29-2.75 c/ha.

Получены новые экспериментальные данные, установлены статистические зависимости, определено влияние элементов технологии (норм высева семян, доз и сроков внесения минеральных удобрений и биологически активных веществ) на формирование семенной продуктивности бекмании обыкновенной, которые позволят получать конкурентоспособную продукцию высокого качества при урожайности семян 3,0—3,5 ц/га.
