Abstract
An assessment of the environmental adaptability of a promising feed crop - festulolium as a part of two-component and three-component grass swards mixtures was made in the conditions of the Republic of Karelia. Based on the results of ten years of research, parameters of plasticity and stability of dry yield weight have been determined by calculating the regression coefficient (bi) and the standard deviation (Si2). All studied grass stands are characterized as highly plastic (bi equal to or close to 1) and stable (Si2 tends to zero): crop productivity increases at a high soil fertility and is relatively uniform in different environmental conditions.
