The amount of yield of grasses and legumes mixture was most diversified and depended on the dose of sludge, ash and their mixtures. Depending on the year of the experiment, the yield of investigated plant ranged between 0.15 and 11.81 t/ha. Significantly highest yield of plant mixture was obtained on the treatment where sludge with ash was used in weight ratio of 1:1, and the lowest one on treatment where solely ash was used. Nitrogen content in plant mixture depended on the sludge or ash dose and their mixtures dose, but also on a cut. Nitrogen content in the plant mixture ranged, depending on the treatment and cut between 11.92 - 35.79 g/kg d.m.
