An impact of grass/clover mixtures (3 grass and 2 clover species) oversown to permanent grassland on dry matter production was carried out at five sites of different altitudes (200-960 m) and soil properties (Table 1) in Slovakia during 1993-95. At zero fertilizer application, the grass/clover mixture oversown to grassland increased annual production from 3.54 to 3.97 t ha⁻¹ (i.e. 19%). At application of PK and two rates of N fertilizer (90 and 180 kg N ha⁻¹ + PK), a relative increase in production was 12, 15 and 6%, respectively. The application of PK to sward without grass/clover mixture oversowing enhanced DM production by 29%. A veraged over the research years and sites, savings on fertilizer represented 60 kg N ha⁻¹ as a result of grass/clover mixture oversown to grassland.

Ensiling capacity and quality of silage were studied as a part of ecosystem research of seminatural, oversown and temporary grasslands. The ensiling capacity was influenced especially by a level of fertilizer nitrogen (N) application and frequency of cuts. The highest content of water-soluble carbohydrates (WSC) and the lowest content of crude protein (CP) was recorded at the 1st cut, but the silage quality was very poor at this cut. Therefore, wilting is necessary at low dry matter (DM) content in herbage. With rising cutting frequencies, CP content increased (r = 0,8221⁺⁺) and WSC content decreased (r = - 0,6689⁺⁺). The lowest WSC content was recorded in oversown grassland and the highest one in temporary sward. Intensive application of N fertilizer showed impact on chemical com position of sward. The content of CP was rising and WSC content decreased (r = - 0,4040⁺). As a result, ensilage capacity deteriorated (Table 1). Silage from the 1st cut had the poorest quality characterized by the highest content of ammonia, free amino-acids and high concentration of butyric acid. The best quality of silage was recorded at the 3rd cut.
