Karbivska U. Productivity increasing of natural and sown meadows in Carpathian region: phytocenological and agrotechnological bases

Formation of sown perennial legume-cereal, legume and cereal agrophytocenoses in Precarpathian region and natural meadow phytocenoses of Carpathian mountain-forest belt was the research object. Aim of the study was to increase productivity and quality of grass fodders in Carpathian region. This paper used the following research methods: fieldwork, laboratory, calculation, analytical, comparative and statistical. To improve fodder base and ecological state of environmental ecological state in Carpathian region theoretically justified usage of ecological-biological and phytocenotic directions of fodder production. Ecological-biological and phytocenotic directions of fodder production are theoretically justified for improvement of fodder base and ecological condition in Carpathian region. Article represents efficiency of mineral fertilizers on cereal grasses, model of their productivity depending on the ratios of basic nutrients and improved measures of natural forage lands improvement depending on different usage mode. Over the years of research (2010-2019) in farms of Ivano-Frankivsk oblast with a total area of 723 hectares improved and developed technology of growing perennial grasses. Yield increase over the years of research ranged from 3,32-3,71 to 5,25-8,85 t/ha with an economic effect of 11,1-21,9 thousand uah/ha. Field of use - agricultural production.
