The paper includes the results on developing technologies for hayfields’ and pastures’ culƟvaƟon in beef caƩle feeding. The re-
search took place on the trial field of Penza Agricultural Research InsƟtute in the period 2015-2016 in accordance with the stan-
dard techniques. The leached chernozem had high amount of available forms of macronutrients. The experiment evaluated less
common components of perennial agrocenoses having high values in producƟvity, forage mass, drought-resistance, longevity,
resistance to constant grazing as well as vegetaƟve apparatus determining their ability to regrowth. All the components were
divided into hayfield and pasture groups according to their morphological and agrobiological features to develop more efficient
swards for special purposes. The experiment also analyzed interacƟon among the components in agrocenoses, their produc-
Ɵvity, response to humidificaƟon and capacity to form second, third and subsequent cuts. The mixture of eastern goat’s rue,
tall fescue and smooth brome performed the best among other pasture swards under various weather condiƟons. It produced
11.3 t dry maƩer (DM), 12.2 GJ exchange energy and 1.43 t crude protein per 1 ha. ProducƟvity of hayfield swards with alfalfa
was high and made up 12.1 t DM ha-1 including 121 GJ exchange energy and 1.28 t crude protein.
Keywords: perennial grass, hayfield, pasture, grass mixture, producƟvity, longevity.
