Drozd O. New Fiber and Oil Flax Varieties Productivity Depending on Seeding Methods and the Fertilizer System

Subject of research - factors that determine the flax plant productivity. The purpose of investigations was to reveal the details of growth, development and yield and produce quality formation of the new modern fiber flax varietyUkrainskyi 3 and oil flax one Pivdenna Nich. The research methods are field, measuring and weight, analytic, computational and comparative, statistical. The value and novelty of investigation consist in the determination of the most rational flax seeding methods depending on the direction of the flax produce use: for fibre, seeds or simultaneously for seeds and fibre; in the establishment of optimal mineral fertilizer doses which secure the unlodging and fit for mechanical harvesting stand formation and fibre manufacture with high spinning capacity. The developed recommendations were introduced at the farms of Zhytomyr region over a sown area of fiber flax 270 ha and oil flax - 30 ha. The field of application - the agricultural production.
