ABSTRACT
LARINAV.I. The productivity of traditional perennial grasses and Bunias orientalis L. in monospecies grass stands and mixtures on the dark gray podzolized soil in the northern Forest-Steppe.
The thesis (manuscript) for the degree of Candidate of Agriculture in the speciality 06.01.12-forage production and meadow management.- Institute of Agriculture of the UAAS, township Chabany, 2001.
In the thesis the research results on the development of energy-saving technology of traditional and little wide-spread perennial crop growing and their mixtures for the purpose of obtaining of stable fresh yields with high feeding quality and the reduction of aggregate power imputs are stated. The dependence of biochemical and microelement composition, forage, nutritiousness on component and fertilizer ratio is investigated. The energy and economic value of these crops growing is conducted.
It is recommended the awnless bromegrass and oriental bunias mixture growing technology which secures by strip component placement against optimal fertilizer background (P60K90 in the autumn and N45 under cuttings) 75.5 hkg/ha of feed units, 10.5 hkg/ha digestible protein (139 g in one feed unit), with metabolic energy concentration in 1 g of dry matter 10.5 MJ.
KEY WORDS: mixture, fertilizers, component sowing in strips, productivity, digestible protein, metabolic energy, energy and economic value.
