Effect of harvesting techniques on yield, biochemical composition of seeds and oilseed oil

The article presents the results of the three-year research devoted to the influence of oilseed flax harvesting techniques on seed yield, harvesting and quality indicators of oil. The experiment has been launched according to the methodology of Dospekhov B.A. on sod-weakly podzolic heavy loamy soil, accompanying observations and studies have been carried out according to universally accepted methods and State Standards (GOSTs). The authors have studied the methods of harvesting oilseed flax of the Ural’skiy variety in the Middle Urals. Desiccation has been performed with Reglon-Air, BP contact drug. According to the study results, it has been found that harvesting techniques have an impact on the yield of oilseed flax seeds. During desiccation of sowing in the period from 50 to 100% of brown pods, followed by single-phase harvesting and during single- phase harvesting of 100% of brown pods without desiccation, the yield has been 1.35-1.51 t/ha and fat collection has reached 609-677 kg/ha. The biochemical composition of seeds and oil does not depend on harvesting techniques.
