Vynnytski V. The influence of agricultural methods upon the growing the arvest and quality of winter wheat grains in the area of the western wood steppe conditions of Ukraine

Object - processes and regularities of the agrophytocenosis formation of winter wheat, the influence of growing technological methods and agrometeorological conditions of vegetation period on the realization of the potential of its grain productivity; aim - improvement of technological methods of growing zoned winter wheat varieties to the level of obtaining stable planned yield and increase of grain quality under conditions of Western Forest-Steppe of Ukraine; methods - visual - for conducting phenological observations; weighting - for determining plant and sowing productivity; chemical - for determining soil agrochemical indices and grain qualitative indices; mathematical and statistical- for objective quantitative estimation of obtained data; calculating and comparative - for determining economic and energetic efficacy of growing technological methods; novelty - the influence of biological peculiarities of the variety, sowing terms and sowing rates and the level of nitrogen nutrition and emistym C on plant growth and development, yield formation and its quality is determined. The indices of economic and bioenergetic efficacy of agrotechnical methods of yield increase and improvement of winter wheat grain quality under conditions of Western Forest-Steppe are determined; results - technological methods of yield increase and improvement of winter wheat grain quality that enable to get about 63,9-71,2 c/ha of high quality with high net profit and low prime cost are worked out; introduced - agroformation of different ownership forms in Lviv region; branch - agriculture
