The results of the field experiences with fiber flax (Linum usitatissimum) are presented. The influence of resowing on the crop yield and the quality of flax fiber of a new flax variety Praleska are shown. The extension and development of anthracnose and other diseases in the early yellow ripeness phase on mono culture of flax are analyzed. The crop yield of fiber flax and the quality indexes of long fiber in the crop rotation and in mono culture are measured. The economic effectiveness of fiber flax growing is accounted. As a result of the lead researches it is established, that at a mono culture of flax there is a decrease in the maintenance of a fiber in trust and its quality indicators: number of a long fiber does not exceed 8 units. At repeated crops of fiber flax on 26–28% productivity of a fiber and seeds in comparison with crops of flax in a crop rotation with an interval of 6 years decrease. Flax crops in crop rotation provides reception of profit of 522 USD/hectare and profitability of 37,3%, at crop of flax on flax the second time profitability decreases to 4,6%, and the third crop of flax on flax becomes unprofitable
