Results of longstanding research on the environmental assessment of Psathyrostachys juncea as a promising crops for grazing agrophytocenoses of Caspian desert are presented. Phytomelioration experiments of downed and eroded pastures in different landscape and geographical zones of the Caspian depression, especially prone to severe wind erosion and salinity, showed that agrophytocenoses formed based on Psathyrostachys juncea, proved more resilient. This species has a high plasticity, drought, salt tolerance. Psathyrostachys juncea is effective phitomeliorant on saline lands. Line of this cereal, which we selected from the collection of All-Russian Institute Plant Growing, currently assigned to the State variety testing.
