Perennial grasses can be used as an alternative source for bioenergy production as they are able to grow in less cultivated areas and might be used as a dual purpose crop – for bioenergy and for forage production. The aim of this study was to investigate the biomass yield of reed canary grass (Phalaris arundinacea L.) and festulolium (×Festulolium pabulare) depending on the used fertilisers, and to evaluate the yield structure using two harvest variations – two-cut and one-cut per season. The field experiment was conducted in the central part of Latvia (56°42' N and 25°08' E) from 2013 to 2015. More productive grass sward formation was ensured by using ash and mineral fertilisers. Comparatively higher proportion of stem yield was obtained from reed canary grass swards, especially mowing once per season. The second mowing contained the lowest proportion of stems for both reed canary grass and festulolium. Key words: festulolium, reed canary grass, fertilisation, yield.
