The studies were carried out in 1998-00 at 20 dairy farms in central-east Poland. The average area of farms was 29.5 ha (soils II-III class). They had barns with 8-40 cows. The aim of the studies was to determine the yield and nutritional value of produced green forages and the way of their utilization. The following green forages were produced and utilized in the farms: grasses, legumes, maize and sugar-beet tops. About 38 percent of green forage from permanent grassland was utilized directly (3/4 on the pasture and the rest in the barns) and the rest was preserved for hay (39 percent) or ensilaged (23 percent) as haylage in ballots. The legume green forage was in 81 percent fed directly (15 percent of it in the pasture and 85 percent in the barns) and the rest was preserved for hay or silage. About 63 percent maize was fed directly as green forage, the rest was ensilaged. Average dry matter (DM), crude protein (CP) and crude fibre (CF) content in DM of directly fed green fodder from permanent grassland was: 24.1, 19.9 and 22.0 percent, respectively. The average content of DM and CP and CF in DM of legumes was 22.3, 22.7 and 25.9 percent, respectively, and in maize: 26.7, 8.9 and 25.1 percent, respectively. The average yields of DM and CP (t/ha) were: permanent grassland - 10.4 and 2.1, legumes 11.8 and 2.7 and maize - 25.2 and 2.24 t/ha, respectively
