Stepanchenko V. Agrotechnical study for a high herbage in the southern part of the Western steppe

The object of study - the process of formation of species composition and productivity of different types of herbage and the performance of legume-cereal grasses using bacterial preparation, plant growth regulator, various types of fertilizers. The purpose of investigations to establish the laws of formation of specific structures and properties of long-term productive cenosis depending on the selection of perennial herbs, the use of biological products, and fertilizers in the southern part of the Western Steppe. Research Methods: Field, laboratory, visual, numerical and weight, mathematical and statistical, computational and comparative. The results - shown in this paper the potential of legumes and legume-grass herbage, defined the mutual use of the drug and bacterial plant growth regulator on their productivity for the different fertilizer and weather conditions in the southern forest-steppe of western private. Revealed patterns of growth and development of perennial grasses sumishok their species composition and productivity agrophytocenoses, especially in the form of plant mass of nutrients and overall feeding value. Introduced in farms Khmelnytsky and Chernivtsi regions of the total area of 155 hectares. Industry - agriculture.
