Puiu V. Scientific Substantion of the Feed Phytocenoses Formation and cultivation of rhe Western Forest-Steppe

The object of the research: the Feed Phytocenoses Formation and cultivation, their productivity and quality of herbal feeds at various technological stage.The aim of the work is to develop the sciantific fondations of the formation and use of forage phytocenoses based on pastures, mixtures of annual and non-traditional perennial forage crops in the green conveyor sistem of the Western Forest-steppe. Methods - field, laboratory, comparative-calculation, statistical. For the first time, an adaptive functional model of the slope-pasture complex has been developed, the regimes of the pasture use of Silphium prefoliatum and Jerusalem artichoke for growing various feed optimized, the rationale for the introduction of the garden burnet as a pasture-based long-term crop was established, the main biometric parameters of pasture cenosis were fixed.Recommendations have been developed for organizing the conveyor cultivation of grass feeds for more than 200 days with productivity within 4-17 t/ga of feed units with low cost. Implementation of scientific development was carried out during 2007-2015 in the farms of Chernivtsi and Khmelnitsky regions on a total area of 2250 hectares. The field of use: agricultural production.
