The changes of dry matter productivity and botanical composition of one licensed variety and eight smooth bromegrass (Bromus inermis Leyss.) genotypes cultivated under drought conditions in foothill region of Central Northern Bulgaria during the period from 1990 to 1992, was studied.
Mean for three years period the greatest dry matter productivity was obtained of KKP No10 genotype (from Bulgaria) – 17.82 t ha–1 (with 19.7 % more than the standard variety Morava (from Bulgaria).
In 3rd harvesting year the same genotype was prevailed in sward with 78.8 %. These bioproductive indices was characterized the same genotype as a most suitable for cultivation under specific soil-climatic conditions of the region.
