DYNAMICS OF GROWTH AND PRODUCTIVITY OF FLAXSEED OIL DEPENDING ON THE CONDITIONS OF HUMIDIFICATION, FERTILIZER, ROW SPACING AND SEED RATE IN THE SOUTH OF UKRAINE
In article results of researches on studying of influence of conditions of humidifying, fertilizer, width of row-spacing’s and norms of seeding on dynamics of development and efficiency of flax olive are displayed at cultivation of culture in the south of Ukraine. The purpose of researches was to establish influence of agrotechnical actions on dynamics of development and efficiency of plants of flax olive in the conditions of the south of Ukraine. The research task consisted in an establishment of influence of conditions of humidifying, doses of mineral fertilizers, width of row-spacing and norms of seeding on duration of the interphase periods, field всхожесть, a survival and productivity of seeds. Field experiments have been spent according to techniques of skilled business. The agricultural technician of cultivation of flax olive on not irrigation and irrigated earths was conventional for conditions of the south of Ukraine. In researches it is established that the irrigation, among technological actions, has the most powerful influence on duration of vegetation of culture, prolonging it for 8-9 days, mainly at the expense of stage phase’s генеративного developments therefore linear indicators of plants and elements of structure of a crop grow. The difference of indicators field всхожести between variants of norms of seeding was in limits from a minus 0.1 to 1.4 at crops with a row-spacing of 15 cm and from a minus 1.2 to 0.6 percentage points at sowing on 45 see At usual ordinary crops in absolute values field всхожесть, at growth of norm of seeding, had the general tendency to increase, whereas on широкорядных crops - to reduction. Actions which promote concentration of plants on area unit strengthened an intraspecific competition that has caused survival reduction in limits to 6.9 percentage points.
