On the contrary, ‘Cyn- thia’ and ‘Näpsä’, which had a low green cover at low N, increased their green cover highly with increasing N levels. Rep- lication was considered a random effect where- as N fertilization as well as species/cultivar were considered fixed effects.	cache/afs-72790.pdf	txt/afs-72790.txt
