Complex use of fertilizers in the technology of oilseed flax in the conditions of the Central Non-Chernozem region

The article presents the results of studies on the use of doses of mineral fertilizers in the agrocenoses of oilseed flax varieties Lirina and Uralsky. The experiments were conducted in the conditions of the Moscow region on sod-podzolic soils in 2022-2023. According to the results of field experiments, it was revealed that with the additional use of ammonium nitrate and CAS-32 in doses of N30, the yield index increased by 49.0-65.0% and 49.5-52.1%, respectively, relative to the control. The maximum yield of flax was obtained in a pilot version using doses of fertilizers N60P60K60 (complex fertilizers) + N30 (ammonium nitrate) + N30 (CAS-32), and amounted to 16.4-16.7 c/ha.
