Karaschuk S. Grain Productivity and Quality of Spring Barley Varieties Depending On the Background of Nutrition Under the Conditions of the Southern Steppe of Ukraine

The object of researches is the processes of growth, development of plants and forming of quality of corn of sorts of barley of fervent depending on a background feed. Purpose of researches - to optimize the nourishing mode of soil at growing of sorts of barley of fervent for the receipt of firm productivity of corn with the high indexes of quality in the conditions of south Steppe of Ukraine. Methods of researches - the field; laboratory; statistical; computation-comparative. Results of researches - For a theory: First in the conditions of south Steppe of Ukraine the processes of growth and development of plants of barley of fervent are trained the Adapt sorts, Stalker, Vakula, forming of their productivity and qualities of corn under act of mineral fertilizers. The separate receptions of growing are improved, in particular, the optimum and computation doses of fertilizers which provide on livery middling suglinkovoy soil the receipt of productivity of sorts at a level 2,5-3,0 t/ha corns with the high indexes of quality are definite. For practice: Application of computation dose of mineral fertilizers under a barley fervent, which determine on a difference between the bearing-out, by optimum and actual maintenance of mobile elements of feed in soil, allows to get productivity of corn of the Adapt sorts, Stalker, Vakula at the level of 2,4-3,2 t/ha. A net income here makes 997-1729 UAH./hа. The sphere of the use is the agricultural enterprises of south region of Ukraine.
