Study of the adaptive potential of fodder shrubs for use in the restoration of degraded semi-desert pasture ecosystems

Abstract. Purpose. The study is aimed at carrying out an adaptation assessment of arid fodder shrubs for the restoration degraded pasture ecosystems in semi-desert zone southern Russia modern conditions climate aridization. Methods. An given adaptive capabilities, including field germination seeds, response to drought, yield leafless Calligonum aphyllum, Eurotia ceratoides, and Kochia prostrata climatic on light chestnut soils. Results. studies were carried severe (lack productive moisture soil throughout summer period) infertile soils (humus content – 0.68–0.74 %). Field seeds was 24.9 (Calligonum aphyllum), 32.6 (Kochia prostrata), 75.6 (Eurotia ceratoides). For selected shrubs, best sowing dates determined November January. By third year growing season, height plants 84–110 cm, which will contribute retention snow pasture. All studied from May September, had a higher than natural grass stand by 1.8–4.5 times. Scientific novelty. under showed high life potential region, drought resistance, low demands fertility long season (140–270 days), productivity, exceeded herbage. use these pastures not only increase their productivity 43–79 %, but also nutritional value terms feed units 1.3 times, digestible protein 1.7 this make it possible forage capacity restored pastures.
