    Changes in Hardseededness Traits of Persian Clover in Relation to Time. I. Trifolium resupinatum var. majus Boiss
    (Univ Namik Kemal, 2006) Tekeli, A. S.; Ates, E.
    This research was carried out at Analyses Laboratory of Field Crops Department in Tekirdag Agricultural Faculty, Trakya University. Germination experiments, which are set up completely randomized blocks with 3 replicates, were performed from seed harvest to end by 15 day intervals. In the experiment, the hard seed rate (%), the dead seed rate (%), germination speed (%), germination vigor (%) in Persian clover (Trifolium resupinatum var. majus Boiss.) which has different color such as yellow, green, red and mixed were determined and their variations in a year were examined. It was determined that seed color and time after harvest could affect all characteristics found out (P<0.01). While the highest rate of hard seed were determining in green seeds (1.46%), the highest dead seed rates in were 3.99% in red seeds. Germination speed was 97.95% in yellow seed and their vigor was found high (98.54%). While the highest hard seed rates were found in 20th (5.25%) and 25th (4.58%) periods, the highest non viable rates were 6.66% in 20th period. The highest germination speed and vigor were determined in 10th period (99.91%, 99.92%, respectively) and the lowest values were obtained from 20th period (87.08%, 88.08%, respectively).

    Nutritive values of some annual clovers (Trifolium sp.) at different growth stages
    (Cuban Journal Agr Sci, 2006) Tekeli, A. S.; Ates, E.
    The aim of this study was to determine the nutritive values of some annual clovers [hedgehog clover (T echinatum M.Bieb.), lappa clover (T lappaceum L.), Mediterranean clover (T spumosum L.), narrow-leaved clover (T angustifolium L.), and Persian clover (T resupinalum L. var. majus Boiss.)] at different growth stages. The experiment was laid out in a two factor factorial in a randomized complete block design, with three replications. The mineral, dry matter and crude fiber contents were determined in Tekirdag (Turkey) during 2001-2002 in dry conditions. The dry matter, crude protein, crude fiber, P, Ca, K, Mg, Ca/P contents and K/P ratios were all affected by the different species and growth stages. The differences in Ca/K between growth stages and clover species were found to be non-significant. The interactions of these traits were not significant. The highest dry matter content was obtained from the hedgehog (11.73%) and Mediterranean (11.51%) clovers. Persian clover produced more crude fiber content (16.16%) than the other species. Differences in Ca, K and Mg for the growth stages were significant. The highest Ca/P (2.74) and K/P (3.37) ratios were found in lappa clover. The maximum Ca/P (2.86) and K/P (3.46) ratios were obtained from the first growth stage (pre-bud). The Ca/K ratio ranged from 0.82 to 0.83.

    NUTRITIVE VALUES OF SOME ANNUAL CLOVERS (Trifolium sp.) AT DIFFERENT GROWTH STAGES
    (Univ Zagreb, Fac Agriculture, 2005) Tekeli, A. S.; Ates, E.; Varol, F.
    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, Tekirdag (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 degrees C for 24 hours and stored for one day at room temperature then found dry matter. Crude protein (%) was determined by Kjeldahl method.

    YIELD POTENTIAL AND MINERAL COMPOSITION OF WHITE CLOVER (TRIFOLIUM REPENS L.)-TALL FESCUE (FESTUCA ARUNDINACEA SCHREB.) MIXTURES
    (Univ Zagreb, Fac Agriculture, 2005) Tekeli, A. S.; Ates, E.
    White clover was sown with tall fescue as tall fescue 25 %+white clover 75 %, tall fescue 50 %+ white clover 50 %, tall fescue 75 %+white clover 25 %, 100% tall fescue and white clover. Plots were 2.5 x 5.0 m, arranged in a randomized block design with three replicates. Row distance 25 cm and sowing rates 10 kg ha(-1) (white clover) and 20 kg ha(-1) (tall fescue) were used. Plots were mowed about 5 cm (stubble height) and then allowed to re-grow to 25-30 cm (plant height). The green fodder yield, dry matter, crude protein, crude cellulose, K/P, Ca/P, Ca/Mg, K/Mg and Ca/K ratios were determined.
