Wow, Armenian wheatgrass is a little harder to research than I thought. So far, this is all I have been able to find, and it is from an article from 1995.

Basic agricultural production spheres are viticulture and horticulture with
well-developed cereal growing and livestock production. Cereal production is
based mainly on spring and winter bread wheat and spring barley. Annual
harvest of these crops in the country presently makes approximately 280-320
thousand tons of grain. 65-70% of this amount is wheat, while 30-35% are
barley and other cereals. The amount of grain produced can satisfy only 25-
30% of the population's demand and is used only within the country.
