In the conditions of the Republic of Belarus there was studied the dynamics of the content of the main feeding elements in top biomass of long fiber flax (Linum usitatissimum), their depletion and coefficients of their consumption by plants from fertilizers. The field experiments were realized on sod-podzolic light-loamy soil on the plots of the Belarusian State Agricultural Academy in 2005-2007. Such mineral fertilizers, as ammonium sulphate, superphosphate double granulated, potassium chloride, were applied in the tests. Presowing treatment of seeds was realized by a moist method, as a basis there was used 0.5% solution of starched gel. Per 1 ton of flax seeds the water expense has made 5 liter. As a result of realized research there was found the positive influence of homobrassinolid on increasing the accumulation of the main feeding elements in top biomass of long fiber flax. The increase in specific depletion of feeding elements under the influence of brassinosteroids was noted. Application of homobrassinolid helped to increase the coefficients of consumption of nitrogen, phosphorus and potassium by the plants of long-fiber flax from fertilizers.
