The effect of the microbiological preparaƟons “Azorhizin”, “Mobilin” and “ Flavobacterin” on the biological pro-
cesses in festulolium plants and its two-year producƟvity in the Pskov region were studied with respect to the
sowing dates. As a result it was found that during the first year of life certain preparaƟons influenced field ger-
minaƟng capacity and Ɵllering. Festulolium seed germinaƟng ability was 7.5 % higher under “Mobilin ” treat-
ment, and 39.4 % higher under “Flavobacterin”. The laƩer also had a notable effect on the number of festuloli-
um Ɵllers before the first wintering. As compared to the check variant the number of Ɵllers aŌer “Flavobacter-
in” was 8.7 % higher, while other variants showed insignificant or no changes. Festulolium dry mass producƟv-
ity in the first year of use was 7.3–9.6 tons ha-1. The highest forage yields were obtained as a result of the first
two sowing dates. The third one decreased festulolium producƟvity by 0.4–1.3 tons ha-1 in the check variants
and by 1.0–2.0 tons ha-1 under microbiological treatments (MT). Being sown at the earliest dates, the crops’
yield gained 0.4–0.5 tons DM ha -1 from MT applicaƟon. Festulolium sown in the second period provided a sig-
nificant increase of 0.4 tons ha-1 aŌer “Flavobacterin”. The festulolium plants treated with the microbiologi-
cal preparaƟons were found to be more drought-resistant in comparison to the check variants. In the second
year of using festulolium crops provided higher yields. Two MT’s developed a posiƟve result: “Mobilin ” was ef-
ficient at all seeding dates and “Flavobacterin” at the first two ones. Dry maƩer yield gain provided by “Mobi-
lin ” made up to 1.6–1.7 tons ha-1 and “Flavobacterin” applicaƟon resulted in 1.0–1.3 tons ha-1 gain. Two years
of managing festulolium showed that “ Mobilin” and “Flavobacterin” were the most efficient for earlier seeding
dates, not later than the second decade of May. TreaƟng festulolium seeds with “Mobilin ” and “Flavobacterin”
resulted in average DM yield of 9.8 to 10.0 tons ha-1 , which is 0.9–1.1 tons ha-1 or 10.1–12.4 % more than in the
reference variants.
Keywords: festulolium, microbiological preparaƟons, sowing date, producƟvity.
