Abstract: 

The article presents a comparative assessment of the effect of such selective herbicides as Herbitox, Furex, Miura and their tank mixtures on the yields of seeds and oil-bearing flax straw, as well as on the elements of its productivity, such as oil content, oil yield, protein content, protein yield, plant height and weight of 1000 seeds. The results of the research has revealed the dependence of yielding capacity of oil-bearing flax seeds on herbicides on the leached chernozem soil of the forest-steppe of the Middle Volga region. The variant of treating crops with Herbitox + Miura (1.0+1.0 l/ha) herbicides in 2019 and in 2020 has been the most effective one and has provided the highest seed- and oil yields. The flax-straw yield indicators in the hydrothermal conditions have been significantly leveled out in 2019-2020. The use of herbicides has not had a significant effect on the oil content of flax seeds and on the «protein content» indicator, while there has been a tendency to a slight decrease in the use of the preparations. The crude protein yield has dependence on both the seed yield and the crude protein content in the seeds. The herbicides used in the experiment have significantly reduced the plant height by 3.7‒6.1 cm.
