Abstract

In article results of researches for 2008-2010 with flax oil grades Brestsky, conducted in north-eastern part of Belarus on sod-podzolic loamy soil are resulted. In field experiments examined the effect of sharing of mineral fertilizers and plant growth regulators on yield and quality of flax. The most effective was the use of brassinosteroids in two stages: the seeds in their inlaying and spraying of crops in a phase of "fur-tree" on the background of complete fertilizer dose N45P60K90. In this case the yield of seeds was 16,7-17,2 ts/ha with oil content in them - 49,7-50,1%, the yield of straw - 41,7-42,3 ts/ha with an average number of 0,5-1,0; conditional net income from 1 ha 1194134-1353820 rbl. at profitability - 217,2-231,8%.
