Flax productivity in seven-field crop rotation on sod-podzolic light loamy soil by using fertilizers and biopreparation

New experimental data have been obtained in the stationary multi-year field experiment on sod-podzolic light loamy soil in 2016-2017. Actual yields of flax straw and seeds of «Levit 1» flax variety in 7-fields system with different levels of fertilizer doses are calculated using balance coefficients in «Mizorin» biological preparation application and without it.

System problems of flax growing in Russia and abroad, the possibilities of their solution

The object of research is the flax complex in Russia and abroad. The Russian flax complex includes agrarian farms and enterprises of processing industries (textile, construction, chemical, etc.). The analysis of the crisis situation of raw materials in the Russian flax complex is given: the lack of finance for flax farms, technological backwardness and low technological discipline at the stages of cultivation and primary processing of flax, high costs and uneven quality of the fiber materials.
