Panakhyd G. The establishment and effective use of unevened sown stands in the Western Forest-Steppe

Subject of research - the process of growth and long-term and new-established grass stand formation depending on fertilization and the use. The purpose - revealing the regularities of species ecologo-biological structure and unevened sown stand productivity formation at different methods of the meadow land improvement of the Western Forest-Steppe. The methods are field, laboratory, visual, measuring and weight, computational, statistical, computational and comparative. The value and novelty of research - details of the old-sown (32-35-year) and new-established (1-3-year) meadow stand growth, development and productivity at the differentiated nitrogenous fertilizer application and use regimes, conducting layer ploughing, the inoculation growth stimulator and microelement use are established; the technology of the meadow land improvement is perfected what allows to prolong the productive longevity up to 35 year use with the obtaining of 5.5 t/ha feed units and 0.8 t/ha digestible protein and early to save 120 kg/ha mineral fertilizer nitrogen. The introduction - the scientific developments are applied in 2008 at the farms of the Pustomyty district of Lviv region over an area 49 ha. The field of application is the agricultural production.
