Özet
The aim of this investigation was to determine the total green fodder yield, total dry matter yield, botanical composition, ground cover index of vegetation, vegetation height, crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) contents and tetany ratios of anthropogenic pasture on north and southfacing slopes under two grazing treatments (free grazing and ungrazed). Slope aspect, grazing treatments and slope aspect x treatments interactions did affect botanical composition. The highest ground cover index of vegetation (89.7%), vegetation height (61.2 cm), total green fodder yield (2.889 t . ha(-1) year(-1)) and dry matter yield (1.031 t .ha(-1) . year(-1)) values were found on north-facing slope, ungrazed. South-facing slope showed the highest CP (110.2-113.7 g . kg(-1)), NDF (47.1-48.4%), ADF (36.5-36.8%), Ca (1.94-1.97%) and P (0.37-0.38%), contents under the free grazing and ungrazed treatments, whereas tetany ratio (0.83-0.85), had its lowest values on these same site. Mg ratio (0.27-0.32%) was unaffected by grazing treatments and slope aspect.
