Samoilenko H. TFormation of yield and grain quality of winter barley, depending on the technological methods of cultivation in Prysyvashsh’a

The object of study - patterns of elements of productivity and grain quality of winter barley plants, depending on the precursors for different periods of sowing and of seeding and fertilizing complex fertilizer "Krystalon special" separately and in combination with ammonium nitrate in dry conditions Prysyvashsh’a. Purpose - to improve existing and develop new elements of the cultivation of winter barley in southern Prysyvashsh’a that would ensure a steady increase survival of plants and their grain production. Methods - field, laboratory, billing, mathematical and statistical. Results: The results of the studies recommended optimum planting dates and seeding rates of winter barley seeds by placing it on a bare fallow, after the sunflower and spring barley, which provides in arid conditions, to obtain from 5.2 to 6.2 t / ha of grain. Lower yields in the rejection of the optimal planting dates ranging from 0.03 to 0.7 t / ha The results tested in production conditions Genichesk Experiment Station and introduced in the farms of Genichesk district of Kherson region on the area of 250 ha. The economic effect in the introduction amounted to 115-280 UAH per ha. The novelty - the first time in a Prysyvashsh’a conducted comprehensive research and improved terms of sowing and seeding rate on the precursor determined the economic efficiency of winter barley cultivation after sunflower, spring barley and fallow. Proved the dependence of quality grain from fertilizing. Industry sector - agriculture. Sector – Agriculture.
