In the soil and climatic conditions of the north-eastern part of the Republic of Belarus there was studied the influence of bio-preparation Biolinum and nitrogen-fixing phosphate-mobilizing bacteria on the seed productivity of long fiber flax (Linum usitatissimum). The field experiments were realized on trial fields of the Institute of Flax in Orsha district of Vitebsk region of Belarus. The soil of a trial plot was sod-podzolic, loamy, had the following agrochemical characteristic: рН (КСl) – 5.2-5.3 on 100 g of soils, humus content on Tyurin – 2.20-2.25%, the content of mobile forms of phosphorus (Р2О5) - 218-228 and exchange potassium (К2О) - 220-225 mg/kg of soil. There were obtained positive results of influence of biological preparation Biolinum on seed productivity and biometric indicators of long fiber flax. Inclusion of bio-preparation Biolinum into the mordant mixture helps to increase the seed productivity of long-fiber flax by 0.82 t/ha. In case of application of nitrogen-fixing phosphate-mobilizing bacteria and bio-preparation Biolinum with protectant Vitavax 200FF in full (2.0 l/t) and lowered (1.4 l/t) doses, the seed productivity exceeded a control variant and fluctuated within the limits from 7.2 to 8.2 c/ha, that was on 1.4-2.4 c/ha higher the control variant.
