Matsiychuk V. The effects of the seeding and fertilization rates on the yieldig capacity of fiber flax varieties under the conditions of right-bank Polissya of Ukraine

Subject of research - the process of fibre flax variwty plant productivity formation at different seeding rates and mineral fertilizer doses. The purpose - the determination of details of fibre flax varieties (Kamenyar and Irma) growth and development and produce yield and quality formation depending on the cultivation technology components. The research mathods are field, morphological, measuring-weight, chemical, physical, dispersion, comparative-computational. The optimal doses of mineral fertilizer application and seed rates for the formation of fibre flax variety crops of optimal density loding resistant, suitable for mechanical harvesting and getting the stable yields of fibre and seeds with the high technological quality are substantiated. The recommendations to the production on the fibre flax cultivation technology component improvement are worked out what secures getting 0.9 t/ha seeds and 1.2-1.4 t/ha fibre in the conditions of the right-bank Polissya. The research results during 2006-2009 are introduced at the farms of Zhitomyr region over an area 190 ha. The field of application - the agricultural production.
