    (2020) Tenikecier, Hazım Serkan; Orak, Adnan; Tekeli, Ali Servet; Gültekin, Birol
    Bu araştırma, Kırklareli ekolojik koşullarında Atatürk Toprak, Su ve Tarımsal Meteoroloji AraştırmaEnstitüsü Müdürlüğü Deneme ve Uygulama Arazisinde 2015-17 yılları arasında iki yıl süre ile tesadüf bloklarıdeneme deseninde bölünmüş parseller deneme desenine göre genotipler ana parselleri, biçim zamanları altparselleri oluşturacak şekilde üç tekrarlamalı olarak yürütülmüştür. Denemede materyal olarak Egebeyazı veSarıefe çeşitleri ile 47.1, 47.2 ve 56.3 nolu çeşit adayları materyal olarak kullanılmıştır. Araştırmada 3 farklıgelişme döneminde (çiçeklenme başlangıcı, %50 çiçeklenme dönemi, tam çiçeklenme) hasat edilen Macar fiğin(Vicia pannonica Crantz.) verim ve kalite yönünden en uygun hasat zamanının belirlenmesi amaçlanmıştır.Araştırmanın iki yıllık ortalama sonuçlarına göre, en yüksek yeşil ot verimi çiçeklenme başlangıcı döneminde(1836.00 kg/da), 47.2 nolu genotipte (1713.78 kg/da), biçim zamanı x genotip interaksiyonunda ise çiçeklenmebaşlangıcı döneminde 47.2 nolu genotipte (2234.00 kg/da) belirlenmiştir. En yüksek kuru ot verimi tamçiçeklenme döneminde (401.00 kg/da), 47.2 nolu genotipte (387.33 kg/da), biçim zamanı x genotipinteraksiyonunda ise tam çiçeklenme döneminde Sarıefe çeşidinde (451.33 kg/da) belirlenmiştir. En yüksek hamprotein oranı %18.85 ile çiçeklenme başlangıcı döneminde, %17.17 ile 47.1 nolu genotipte, biçim zamanı xgenotip interaksiyonunda ise çiçeklenme başlangıcı döneminde 47.1 nolu genotipte (%19.98) saptanmıştır. Enyüksek ADF ve ADL oranı %37.02 ve %6.49 ile tam çiçeklenme döneminde, %33.93 ve %5.71 ile Egebeyazıçeşidinde, biçim zamanı x genotip interaksiyonunda ise tam çiçeklenme döneminde Egebeyazı çeşidinde(%19.98 ve %7.08) saptanmıştır. En yüksek NDF oranı ise %47.20 ile tam çiçeklenme döneminde, %47.05 ileSarıefe çeşidinde belirlenmiş, biçim zamanı x genotip interaksiyonu ise istatistiki olarak önemli bulunmamıştır.İki yıl süre ile yürütülen araştırmada; ilk yıl iyi gelişme gösteren Macar fiğinden %50 çiçeklenme döneminde enyüksek yeşil ot verimi alınmıştır. İkinci yıl yağışlı başlayan bahar ayının kurak sezonla devam etmesi nedeni ile enyüksek verim çiçeklenme başlangıcında (2178.67 kg/da) alınmış, onu izleyen her iki dönemde de verim düşüşüyaşanmıştır.

    Changes in Hardseededness and Other Characteristics of Trifolium Resupinatum Var. Typicum Fiori Et Paol. (Fabaceae) Seeds Stored in Uncontrolled Conditions
    (Fac Agriculture Osijek, 2008) Tekeli, Ali Servet; Ateş, Ertan
    This research was carried out at Analyses Laboratory of field Crops Department in Agricultural Faculty, Namik Kemal University, Tekirdag, Turkey. The germination experiments, which were set up as completely randomized blocks with three replicates, were performed from seed harvest to end in 15 day intervals. In the experiment, the hardseededness (%), dead seed (%), germination speed (%) and vigor (%) ratios in Trifolium resupinatum var. typicum Fiori et PaoL which has different seed color such as yellow, red, green 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. While the highest hardseededness was determining green seeds (68.4%), the highest dead seed ratio was 2.4% in red seeds. The germination speed was 31.0% in yellow seed and their vigor was found high (38.9%). While the highest hard seed ratio was found in 10th (94.3%) germination period, the highest dead seed ratio was 3.1% in 18th germination period. The highest germination speed and vigor were counted in 21st -26th period and the lowest values were obtained from 10th period.

    Genotype x environment interaction and stability analysis for dry matter and seed yield in field pea (Pisum sativum L.)
    (Inst Nacional Investigacion & Tecnologia Agraria & Alimentaria-Inia-Csic, 2009) Açıkgöz, Esvet; Üstün, Abdullah; Gül, Iftikhar; Anlarsal, E.; Tekeli, Ali Servet; Nizam, İlker; Yavuz, M.
    The objectives of this study were to evaluate dry matter (DM) yield and seed yield of six leafed and semi-leafless pea (Pisum sativum L.) genotypes, and to compare them for these traits. Evaluation of genotype x environment (G x E) interaction, stability and cluster analysis were also carried out at eight diverse locations with typical Mediterranean and Mediterranean-type climate during the 2001-2002 and 2002-2003 growing seasons. Significant differences were found among the pea genotypes for DM and seed yield on individual years and combined over years, and in all locations. All interactions which related to G x E interaction showed significance (P>0.001) for DM and seed yield. The highest yield (4789 kg ha(-1)) was obtained from the leafed genotype 'Urunlu'. However, stability analysis indicated that for DM yield, the leafed genotypes 'Golyazi' and 'Urunlu' should be grown in low yielding and high yielding environments, respectively. Cluster analysis, based on grouping locations, showed that P101 was the preferred variety in low yielding environments, and P98, in high yielding ones. It was suggested that the use of both stability and cluster analyses might give better results. Comparison of cluster and stability analyses showed that the stability analysis fails to recommend cultivars to different regions where yield potential showed significant differences. It seems, however, that cluster analysis could be a powerful tool to examine G x E interaction. If the number of environments was sufficient, a separate stability analysis could be run in each cluster.

    Plant growth stage effects on the yield, feeding value and some morphological characters of the fiddleneck (Phacelia tanacetifolia Benth.)
    (2010) Ateş, Ertan; Coşkuntuna, Levent; Tekeli, Ali Servet
    The aim of this investigation was to determine the yield, some morphological characters and feeding values of fiddleneck (Phacelia tanacetifolia Benth.) at different growth stages (budding, half bloom and full-bloom). The experimental design was a randomized complete block with three replicates. The maximum plant height (106.33 cm.) was measured for fiddleneck at full-bloom stage. The budding growth stage had highest leaf/stem ratio (0.60). The half bloom and full-bloom growth stages showed the highest green fodder yield (60.20 to 60.47 t ha-1) and dry matter yield (9.77 to 9.87t ha-1). The budding growth stage showed higher value than other growth stages for CP (13.22%). The highest ADF ratio (37.33%) was determined from plants at the full-bloom stage, whereas the maximum NDF (45.43-45.60%) and ADL (22.43-23.70%) ratios were found at the half bloom and full-bloom stages. There were no significant differences between the leaf length (19.76-20.11 cm), number of leaves per plant (27.65-30.21), main stem diameter (5.48-5.77 mm), Ca (0.97-0.98%) and Mg (0.37-0.39%) contents. Differences in P (0.42-0.67%) and K (2.27-2.38%) contents of the growth stages were significant. It is concluded that in the subtropical region under dry conditions, fiddleneck can be sown to obtain maximum green fodder yield, dry matter yield and mineral contents. Fiddleneck provided a balanced feed for animals throughout the growing season.
