Recently the growth rates of bioenergy production are leading to the waste – digestate and wood ash increases, which are essential to be managed in the most efficient way. In order to study the waste products application possibilities for energy crops – reed canary grass (Phalaris arundinacea L.) and festulolium (×Festulolium pabulare), the fertilisation trials were established in 2012 at the Skriveri Research Institute of Agriculture. The following treatments were compared: (1) without fertilisers (control); (2) mineral fertilisers; (3) wood ash; (4) digestate once per season; (5) digestate two times per season. Similar amount of main plant nutrients (N, P2O5, K2O) were provided in all treatments. The biomass yield was harvested using two cutting regimes: two cut and one-cut harvest system. This article summarizes the findings on the grasses productivity in 1st year of use. The productivity of perennial grass biomass was dependent on the type of applied fertilisers, grass species and cutting regime: the highest average dry matter yield was produced by reed canary grass. The highest dry matter (DM) yield in average for both grass species were obtained by harvesting once per season – in autumn at the phase of crop senescence when wood ash and mineral fertilisers were used as fertilisers.
