Özet
Bu çalışma, Atatürk Toprak, Su ve Tarımsal Meteoroloji Araştırma Enstitüsü uygulama alanında mevcutplastik serada, farklı tuzluluk düzeyindeki sulama sularının domates bitkisinin kök gelişimine etkisini izlemekamacıyla yapılmıştır. Çalışmada iki farklı tuz konsantrasyonuna sahip sulama suyu (T1: 0.38 dS m-1 ve T2:5.0 dS m-1) kullanılmış ve domates bitkisinin kök gelişimi dört farklı derinlikte (0-25, 25-40, 40-55, 55-70,70-90 cm) minirhizotron kamera yardımıyla izlenmiştir. Elde edilen kök görüntüleri RootSnap programıyardımıyla analiz edilerek 5 farklı derinlikteki kök miktarları yüzdesel olarak hesaplamıştır. Elde edilensonuçlara göre; T2 sulama suyu ile sulanan domates bitkisinin kök gelişimi, tuz miktarının yoğunlaştığı0-25, 25-40 cm’lik toprak katmanında olumsuz olarak etkilenmiş ve buna bağlı olarak kök yüzdesi düşükolmuştur. Kullanılan sulama yöntemi kaynaklı olarak alt katlarda (40-55, 55-70, 70-90 cm) tuz birikimidaha düşük seviyelerde olduğundan, kök yüzdesinin arttığı gözlenmiştir. T1 sulama suyu ile sulanankonunun farklı katmanlardaki tuz miktarları kök gelişimini ve su alımını olumsuz yönde etkilemeyecekdüzeylerde olduğundan, kök yüzdesi tüm katmanlarda birbirine yakın oranda belirlenmiştir.
The aim of this study is to observe the effect of irrigation water of different salinity level on root development of tomato plant and carried out Atatürk Soil, Water and Agricultural Meteorology Research Institute’s Greenhouses. Irrigation water (T1: 0.38 dS m-1 - T2: 5,0.dS m-1) with two different amounts of salt was used in the study and the root development of the tomato plant was examined at four different depths (0-25, 25-40, 40-55, 55-70, 70-90 cm) were monitored with the aid of a minirhizotron camera. The obtained root images are analyzed with the help of the RootSnap program to calculate the root quantities in 5 different depths as a percentage. As a result of the research, the root growth of tomato plant with T2 irrigation water was adversely affected by salt accumulation in the soil with high salt content (0-25, 25-40 cm) and accordingly root percentage was low. In the low-salt lower layers (40-55, 55-70, 70-90 cm), the percentage of root was increased because the salt accumulated in the soil was low . In T1 irrigation water, the percentages of roots were obtained in close proximity in each layers, since that would not affect root development and water uptake negatively.
