Farkl Doğrudan Ekim Makinalar ve lerleme Hzlarnn Yazlk Fi ve Klk Budayda Topran Baz Fiziksel Özellikleri ile Bitki Çkna Olan Etkileri

Aratrmada; yazlk fi ve klk budayda, farkl gömücü ayaklara sahip 3 adet dorudan ekim makinas ile 4 farkl traktör ilerleme hznn topran baz fiziksel özellikleri ile bitki çklarna olan etkilerinin belirlenmesi amaçlanmtr. Denemeler srasnda, çapa (NS-1) tek diskli (NS-2) ve kanatl çapa (NS-3) tip gömücü ayaklara sahip üç farkl dorudan ekim makinas dört farkl traktör ilerleme hznda (0.75 m s-1, 1.25 m s-1,1.75 m s-1 ve 2.25 m s-1) kullanlmtr. Elde edilen sonuçlara göre en iyi toprak fiziksel özellikleri çapa tip gömücü ayaklara sahip dorudan ekim makinasnn kullanld parsellerde gözlenmitir. Traktör ilerleme hzlarnn topran fiziksel özelliklerine olan etkileri her iki bitkide de istatistiksel olarak önemsiz bulunmutur. Ortalama çk süresi ve çimlenme oran yüzdelerine her iki bitkide de dorudan ekim makinalar önemli düzeyde etkili olurken, benzer etki traktör ilerleme hzlarnda gözlenmemitir. Yazlk fi ve klk budayda en yüksek çk oran, çapa tip gömücü ayaklara sahip dorudan ekim makinasyla ekim yaplan parsellerde elde edilmitir.

Effects of Different No-Till Seeders and Tractor Forward Speeds on the Soil Physical Properties and Seed Emergence of Summer Vetch and Winter Wheat

The aim of this study is to determine the effects of different no-till seeders and tractor forward speeds on some of soil physical properties and seed emergence of summer vetch and winter wheat. In the research, three different types no-till seeders with hoe (NS-1), single disc (NS-2) and winged hoe (NS-3) type openers were used with four different tractor forward speeds (0.75 m s-1, 1.25 m s-1,1.75 m s-1 and 2.25 m s-1). According to obtained results, the no-till seeders with hoe type furrow opener (NS-1) provided better soil physical properties than the other two no-till seeders. However, tractor forward speeds had no effect on physical properties of soil for both summer vetch and winter wheat. No-till seeders had a significant effect on the mean emergence time (MET) and percentage of emergence (PE) while tractor forward speeds had no effect on these values in both summer vetch and winter wheat. The highest PE was observed at the plots sown with NS-1 seeder in both summer vetch and winter wheat.
