Iskra V. Productivity formation of alfalfa-grass swards depending on the method of sowing and fertilizer in northern Forest-steppes

A research object - is a process of growth, development and yield formation, quality seeded alfalfa-grass mixtures, underground mass conservation laws in alfalfa grass mixture depending on their composition and processing methods A research aim - is an exposure of conformities to law of forming of seeded alfalfa-grass swards Research methods - the field, measuring and weighing, laboratory, visual, calculating, mathematically-statistic For the first time on black ashed to typical humus in northern Forest-steppes developed and scientifically grounded elements of effective new technologies (bandpass crops), which help to reduce the negative impact on alfalfa grasses and preserve it in the grass. Improving resource saving technology of high alfalfa-grass swards on black ashed in Forest-steppe, which ensures obtaining 34.5 - 46.0 t/ha of green mass of highly, 1.36 - 1.32 t /ha fodder units of content in each 130 - 133 g digestible protein. Developments author implemented in Ltd. "Khliborob" (v. Velyka Vilshanka, Vasylkivskiy region, Kyiv region) on the area 54 ha and FG "Uzin-Agro" (Uzin, Bilotserkivskyi region, Kyiv region) on the area 63 ha. Areas of use - agriculture production
