Abstract

The harvest of seed and green mass of alfalfa cultivars and population went down meaningfully during the last 2 years (2014, 2015). This period was characterized by higher values of average air temperature (by 1.0°С) and decreased relative air humidity (by 6.0%) and rainfall during the vegetation of alfalfa (by 107.0 mm). New varieties Sirena and Natali, as well as populations 2/08 and 6/04, were characterized by the highest yield of green mass and seeds in competitive variety trial.
