Abstract

This study was conducted between the years of 2001-2002 in the experimental area and laboratory of Field Crops Department of Agriculture Faculty in Trakya University, Tekirdağ (Turkey). Five different clovers [Persian (Trifolium resupinatum L. var. majus Boiss.), Mediterranean (T. spumosum L.), narrow-leaved (T. angustifolium L.), hedgehog (T. echinatum M. Bieb.) and lappa (T. lappaceum L.) clovers] were used. Each plot consisted of 8 rows with a length of 5 m. Row spacing of 30 cm and sowing rate of 10 kg ha-1 were used. Sowing times were on 2.25.2001 and on 2.28.2002. Plots were not irrigated and fertilized after sown and harvest. One cut was taken in both years at 4 growing stages such as pre-bud, pre-bloom, 50% bloom and full-bloom. The central 1 m-2 sections was cut at ground level for dry matter. Approximately 500g samples were dried at 55 °C for 24 hours and stored for one day at room temperature then found dry matter. Crude protein (%) was determined by Kjeldahl method.
