Summary. In the researches conducted in 2012-2013 on medium loamy middle podzol soil, the most widespread one among arable lands of the Central Urals, the influence of preseeding processing of seeds by biological preparations, microfertilizers and fungicides on seed efficiency of olive variety of flax VNIIMK 620 is determined. The scheme of experiment included the following variants: without processing (control 1); water (control 2); extract from sprouts of a winter rye; potassium humate; TMTD; mixture of microfertilizers; mixture of microfertilizers + TMTD; humate of potassium + TMTD; extract from sprouts of a winter rye + TMTD; Borogum M. Significant increase in productivity – on 5…21 g-m2, or 6…28%, provided all studied variants, in comparison with lack of processing of seeds and moistening by water. Preseeding processing of seeds by TMTD fungicide, mix of microfertilizers, and also joint processing of TMTD with microfertilizers, extract from sprouts of a winter rye and a humate of potassium increased on 4…14 g-m2 (5…17%) efficiency of flax seeds, in comparison with options of application of biological preparations – extract from sprouts of a winter rye, a humate of potassium and Borogum M. The greatest productivity of seeds – 92…96 g-m2 in options with processing of seeds of TMTD separately, together with microfertilizers, with extract from a winter rye, with a potassium humate, separately microfertilizers is caused by increase in density of standing of plants to harvest – on 29…60 pcs-m2, the mass of seeds from a plant – on 0,015…0,024 g, their quantities – on 2,3…2,8 pcs, in comparison with similar indicators without preseeding processing of seeds. Use of a humate of potassium separately and together with TMTD, Borogum M provided the growth on 0,2…0,4 g of mass of 1000 seeds, in comparison with not treated and humidified with water seeds.
