Agro-energetic and economic efficiency of technologies for the creation and use of semishrub-grass pasture agrophytocenoses in the Caspian semi-desert

The article presents the results of 8 years of research for establishing the economic and agro-energetic efficiency of technologies for the creation and use by sheep of various types of seeded pastures (Kochia–Artemisia, Camphorosma–Artemisia, and Eurotia–Artemisia) in the semi-desert zone of Kalmykia. The technology of creation of Kochia–Artemisia pasture, which differed with high conditionally net income (8785 rub./ha) and the lowest cost of feed (1 rub. 85 kop. per 1 feed un.), showed the highest economic efficiency.
