The influence of climatic conditions on the hay yield of the ceratain types of grass

The aim of this study was to examine the possibilities of cultivation and yields of perennial grasses of foreign origin in the western and eastern Croatia. Accessions within a species of grass were minimally distinguished by yield of green mass and hay. In contrast, the differences in crude protein yield were significant. The char-acteristic with the highest variations was the yield of protein per unit area (coeffi-cient variability CV 8.16%). The location impact is significant only for the yield of hay and crude protein, while the impact of the year long locations was not sig-nificant for all characteristics. Impact of year as a separate variable had a signifi-cant influence on all the properties of the yield. The highest yield of green mass and hay had Italian ryegrass (TLJ2) while cocksfoot (KO2) achieved the highest yield of protein.
