Sustainability of agriculture is only ensured by proper soil and water preservation practices. The idea of re-use of wastewater in agriculture is the critical issue regarding with the use and preservation of water resources in today’s water scarce conditions. However, heavy metals and trace elements in waste water are important contaminants for plants and soils. Heavy metals create a significant threat on health of environment, plants and eventually on the health of humans and animals. In this study, eggplant seedlings were irrigated with increasing doses of Copper (Cu), zinc (Zn), lead (Pb), cadmium (Cd)-containing irrigation waters to investigate the effects of heavy metal concentrations on plant morphological characteristics (stem length, root length, leaf fresh and dry weight, root fresh and dry weight, leaf area) and soil properties (pH, electrical conductivity, cathion exchange capacity, organic matter). While significant changes were not observed in soil properties, effects of heavy metal treatments on plant morphological characteristics were found to be significant (p< 0.05).

Bakır, Çinko, Kurşun ve Kadmiyum’lu Sulama Suyu Uygulamalarının Bazı Patlıcan Genotiplerinin Büyüme Parametrelerine ve Toprak Özelliklerine Etkisi

Tarımın sürdürülebilirliği, ancak uygun toprak ve su koruma uygulamaları ile sağlanmaktadır. Tarımda atıksuyun yeniden kullanım fikri, su kıtlığının yaşandığı bu günlerde su kaynaklarının korunması ve kullanımında kritik öneme haiz bir konudur. Ancak, atıksulardaki ağır metaller ve iz elementler bitki ve topraklar için önemli kirleticilerdendir. Ağır metaller, çevre ve bitki sağlığının yanında insan ve hayvan sağlığı üzerinde önemli bir tehdit unsurudur. Bu çalışmada, artan dozlarda Bakır (Cu), Çinko (Zn), Kurşun (Pb) ve Kadmiyum (Cd) içeren sulama sularıyla sulanan patlıcan fidelerinin, bitki morfolojik özellikleri (bitki gövde uzunluğu, kök uzunluğu, gövde yaş ve kuru ağırlığı, kök yaş ve kuru ağırlığı, yaprak alanı) ve toprak özellikleri (pH, elektriksel iletkenlik, katyon değişim kapasitesi, organik madde) üzerinde ağır metal konsantrasyonlarının etkileri incelenmiştir. Ağır metal uygulamalarının toprak özellikleri üzerindeki değişimleri istatistiksel açıdan önemsiz iken, bitki morfolojik özellikleri üzerinde (p <0.05) anlamlı olarak bulunmuştur.
