Aim of research is to determine the processes of yield capacity formation of an-nual fodder crops depending on the sowing rates and level of mineral nutrition in the system of raw material conveyor that would provide production of ecologi-cally safe fodders. Methods of research are field and laboratory accompanied with agrochemical and bio-morphological researches using statistic and comparative-calculative methods. It is established that green mass yield in two-component mixtures that include cereal and legume crops provides 21,2-26,5 t/ha, with crude protein content of 5,66-7,53 t/ha, a three-component mixtures of 20,1-27,1 and 5,33-7,81t/ha ac-cordingly. Economic effect is 85-90 grn/ha. Scientific novelty of this work is in revealing competitive ability of different fodder crops grown in mixed sowings and influence of the level of mineral nutrition and ratio of components on the formation of green mass yield. Results of researches are introduced at the farm "Rosiya" of Pohrebysche region, Vinnytsia oblast. On the territory of 50 ha increase of green mass yield has been 15,7%. It is recommended for the use in the branch of field fodder production. Product Description popup.authors Гетьман Надія Яківна Кифорук Василь Васильович popup.nrat_date 2020-04-02 Close
