Abstract
The article is devoted to the study of the biomorphological features of Elytrigia trichophora under conditions of introduction in the mountain semi-desert z one and the determination of their economic prospects for introduction into rainfed crops. The research results showed that, in the Tashkent area, the number of generative shoots is almost the same, but they are 30 - 31 cm long and the number of partial bushes is 4 - 5 more than in Chartak. The root system lengthens by 18 - 25 cm per year, and the number of roots of the first order in the third year of vegetation increases to 93 . 6 ± 2 . 31 pieces, they branch up to the III-IV order. The duration of medium-aged generative plants in the Chartak area is 5 - 6 years, and in the Tashkent area, it is 1 - 2 years longer.
