Influence of cenosis density on the yield and quality of fibre flax crops

Abstract

The article presents the results of the field experiments on the influence of cenosis density formed by the seeding rate of 20, 22 , 24, 26 million pcs./ha, on the yield and quality of flax raw materials. The field experiments were conducted under dry and slightly dry weather conditions in 2021 and 2022 and extreme moisture conditions in 2023. Under changing climate conditions with a warming trend in order to obtain competitive flax products, it is advisable to increase the seeding rate up to 24–26 million pcs./ha, which will ensure stem density of 18–19 million pcs./ha, seed yield of 5–6 c/ha, flax straw of 39–40 c/ha and cultivation profitability of 33–36 %.
