Obtaining good vegetal yields and with high quality from grasslands needs the use of the improvement measures. Among these, fertilisation has a determining role on the obtained yield and quality. This work presents aspects concerning the effect of different fertilisation types (chemical, organic, and mix) on the percentage and yield of crude protein. The experimental plots are set on one of the grassland of Grădinari locality (Caraş-Severin County) during 2006-2007. There are applied different fertilisation doses, the most efficient in 2006 being 10 t/ha manure applied once, and in 2007 the chemical fertilisation dose N 100+100 P 50 K 50 .
