Abstract

The effect of fertilizers and insecticides on the yield of oil flax varieties in the Middle Ural in years 2016-2018 were determined under our study. The soil of the experimental locations was characterized as semi-cultivated. The preceding crop before our study was the winter triticale. The experiment scheme included the following options: factor A – grade: VNIIMK 620 flax (standard); Severniy flax; factor B – fertilizer: no fertilizers (for the control group); the planned seed yield of 12 kg/ha; factor C – insecticide: no treatment (control); water spraying of seeding (for the control group); seed treatment with “Tabu”; “VSK” (1.0 l/t); seeding processing with “Karate”, “MKS” (0.1 l/ha); seeds and seeding treatment with “Tabu”, “VSK”, “Karate”, “MKS”. Mineral fertilizers increased the seed yield by 1.0 kg/ha or 10.8% in the cultivation of oil flax varieties VNIIMK 620 and Severniy. Seed treatment before sowing with an insecticide “Tabu” or spraying of the seedlings with “Karate” insecticide, or their sequential use, (with the use of mineral fertilizers and without them), increased the flax seed yield by 0.5-1.5 metric centners/hectare. The increase in seed yield with the use of fertilizers is caused by an increase in seed germination by 2%. At the same time, more plants were ready for harvesting – by 16 units/m2, which had more capsules – by 0.7 pieces; and seeds – by 2.7 units, which led to an increase in the seed mass by 0.04 g. Increase in seed yield, when using the insecticide “Tabu” as a seed treatment before sowing, and the “Karate” insecticide for processing seedings separately and with their sequential use, contributed to the germination capacity increase by 4–5%. As a result, the viability of plants during the growing season was improved by 2–3%, which affected the density of the plants before harvesting and the productivity of the oil flax, increasing the abovementioned indicators by 34–48 units/ m2; by 0.2-0.8 units – capsules quantity; by 2.5-2.7 units – seeds quantity; 0.01-0.02 g – seed mass.
