EFFICIENCY OF FIBER FLAXBACTERIZATION BY MICROORGANISMS ISOLATED FROMVERMICOMPOST

Abstract

Fiber flax is one of the most important industrial crops of the domestic crop sector, which is of great national economic and strategic importance. And at the same time fiber flax is one of the crops most difficult for cultivation. Currently, the use of biological preparations with systemic action, combining the properties of plant growth stimulators and means of protection, is one of the most effective methods to increase germination of fiber flax and its resistance to disease causing agents. The results of laboratory and field tests have shown efficiency of bacterization of fiber flax seeds by enrichment cultures of bacteria isolated from the coprolites of earth worms Eisenia fetida. Presowing treatment of fiber flax seeds (TOST-4 variety selectie in the Siberian Research Institute of Agriculture and Peat) along with spraying of vegetating plants with enrichment culture of phosphate bacteria had a positive effect on the plants’ preservation in the field experiments, increase in plant height, yield of seed and flax straw. Bacterization of flax seeds by Pseudomonas sp. reduced the degree of Fusarium infection of plants, increased the weight of 1000 seeds and plant height.
