Analysis of the green mass yield’s components of Sudangrass and Sorghum x Sudangrass hybrids was made, the yield obtained by mowing in brooming and flowering stages during 2010-2011.The results of the tests confirm the high productivity potential of the sorghum-sudangrass hybrids in conditions of optimum soil’s water reserve and temperatures during the vegetation. The sorghum-sudangrass hybrids show excellent adaptive potential in conditions of more often going extreme deviations from the agro-climatic norms. The total and the relative productivity in the separate swaths does not differ substantially in the brooming and the flowering stages. The lack of enough moisture reflects most significantly on the productivity in the later swaths and on the intensity of dry matter accumulation. The agroclimatic conditions do not affect the favourable leaf part in the green mass.
