Veklenko Y. Improvement of technological methods of creation and ways of utilization of polytypic grass stands on arable lands of the central Forest-steppe of Ukraine

Object - processes and laws of formation of specific structure of agrocenosises from a perennial grass family and leguminous plants, their productivity and a forage quality in dependence on technological methods and ways of use; the purpose - to improve technological methods of creation and ways of use of polytypic grass stands on arable lands of the central Forest steppe in conditions of natural maintenance with a moisture of soil; methods - visual, measuring-weight, laboratory - chemical, mathematics - statistical; novelty - for the first time for the Central Forest steppe of Ukraine in conditions of natural maintenance is advanced by a moisture of soil technology of creation of polytypic grass stands for cultivated grasslands which enables to unite mineral and "biological" nitrogen, to extend the season of use of a grass stand in pascual ripeness on 10-15 days. The positive role of green manure crops, in particular, white mustard and a white lupin, at creation sown hay-pasture grass stands, is proved. Values birdsfoot trefoil and goat's-rue in formation of a hay-pasture grass stand, its productivity, improvement of a forage quality and the savings of power inputs fixed. Optimum regimes of the beginning of a grazing of animals on sown grass stands are developed and the fodder and economic assessment hays use and is given to their pascual use; results - are developed technological methods of creation of cultivated grasslands for cows on forage lands of the Forest steppe which in conditions of natural humidification provide an output 5-6 t feed units and 0.9-1.2 t a protein from hectare and reduce by 25-30 % of an expense of power and material resources; introduced - agroformations of Vinnitsa region; range - an agriculture.
