Pre-sowing Treatment of Seeds and Productivity of Oil Flax Varieties in the Conditions of the Northern Trans-Urals

Abstract

AbstractThe studies were carried out in zone of the northern forest-steppe of the Tyumen region on experimental field of the State Agrarian University of the Northern Trans-Urals in 2018–2020. The purpose of the research: to study the effect of pre-sowing treatment of seeds with organo-mineral fertilizer Chudozem, the Hydromix complex and the Rostock stimulator on the yield and quality of seeds of oil flax varieties. As a result of the research, it was found that the number of seedlings in flax varieties increased in the variants where the seeds were treated with Chudozem liquid fertilizer and the Hydromix complex. In the variety Isilkulsky, in addition, there was also a variant with seed treatment with a stimulant Rostock. The studied methods of pre-sowing seed treatment had a positive effect on the mass of grain from the plant. The greatest increase in indicator compared to the control (33.3%) was noted in the Isilkulsky variety in the variant with seed treatment with Chudozem fertilizer. Pre-sowing treatment of seeds with the Rostock stimulant and Chudozem fertilizer contributed to an increase in the mass of 1000 seeds. At the same time, Legur and Isilkulsky varieties responded to treatment with the Rostock stimulant to a greater extent (increase in the indicator relative to the control – 0.41 and 0.39 g, respectively), and August and Sokol varieties responded to the variant where Chudozem acted (increase in the indicator relative to the control 0, 29 and 0.48 g, respectively). The seed yield of oil flax varieties August and Legur increased in the variants with seed treatment with the Rostock stimulant and Chudozem fertilizer. The largest increase to the control (23.3%) was obtained in the August variety in the variant where the stimulant Rostock acted.KeywordsOilseed flaxVarietiesPre-sowing treatment of seedsYieldSeed oil contentProtein content
