Vishnivska Y. Formation productivity oil flax depending of growing technology under conditions of the northern Forest-Steppe

The object of researches is Processes of growth, development and forming of productivity of sorts of flax of oil-bearing and indexes of quality of seeds and fibre depending on influencing of elements of technology of growing. Purpose of researches - to Set the features of growth, development of plants and forming of productivity of flax of oil-bearing depending on influencing of elements of technology of growing. Methods of researches - computation; visual; measuring-gravimetric; laboratory; biochemical; statistical; computation-comparative. Results of researches - For a theory: First for the terms of north Forest-steppe of Ukraine for grey forest soils it is studied and bringing of optimum doses of mineral fertilizers is set at growing of flax of oil-bearing. Expedience of predposevnoy treatment of seeds is set by stimulus of growth and biofungitsid. The features of growth and development and forming of elements of productivity depending on the explored factors are exposed. Complex influence of elements of technology on productivity of ecological types of flax of oil-bearing is set, his economic and power efficiency of production of seeds and fibre. For practice: To development of recommendations in relation to the use of the system of fertilizer and predposevnoy treatment of seeds by preparation a stimulant growth - reksolin and biofungitsidom of mikosan, that productivity of seeds provides possibility of receipt on every hectare at the level of 2,02-2,23 t. The sphere of the use is agricultural enterprises for growing of flax.
