This experiment was carried out to determine the effects of nitrogen (0 and 80kg ha^-1) and lime application (0, 2 and 4 t ha^-1) at the seeding time on the soil properties, weeds development, dry matter(DM) yield and nutritive value in alfalfa(Medicago satiua L.) meadow, 1988 to 1989. Soil pH and nutrients on 6 months after adjustment with lime was increased with increasing level of lime. Percentage of weeds was decreased with increasing of N fertilization and lime application. Higher DM production and crude protein yield(CPY) of alfalfa were observed by N fertilization at the seeding time. Also the DM production, CPY, and is vitro digestible dry matter were increased significantly with higher lime application(p $lt;0.05). Based on the results, it is suggested that enough lime application at seeding time of alfalfa are more effective for forage production and nutritive value. Also N fetilization is desirable for alfalfa growth.
