Atıksu Arıtma Suyunun Gazanya Yetiştiriciliğinde Tekrar Kullanılabilirliği

Endüstriyel gelişmeler, hızlı nüfus artışı ve göçler atık su miktarında yükselişe neden olmuştur. Temiz su kaynaklarını kirletilmesi, kaynakların azalması ve kuraklık temiz su ihtiyacını arttırmıştır. Bütün bu etmenler temiz su kaynaklarının etkin bir şekilde kullanımını zorunlu hale getirmiştir. Atık su arıtma suyu sanayi, tarım, orman ve peyzaj alanlarında tekrar kullanılabilmektedir. Bu araştırma, 2015 Nisan-Ekim ayları arasında atık su arıtma suyunun gazanya yetiştiriciliğinde tekrar kullanım şansını belirlemek için yürütülmüştür. Araştırmada kullanılan atık su arıtma suyu Çanakkale, Kepez Arıtma Tesisleri'nden temin edilmiştir. Gazanya bitkileri haftada bir yalnız musluk suyu ya da atık su arıtma suyu ile sulanmıştır. Deneme tesadüf parselleri desenine göre üç tekerrürlü kurulmuş, her parselde dört bitki yer almıştır. Denemeden elde edilen verilere varyans analizi ve Pearson korelasyon testi uygulanmıştır. Sonuçlar Gazanya yetiştiriciliğinde atık su arıtma suyunun sulamada kullanımının uygun olduğunu göstermiştir. Atık su arıtma suyu uygulanan parsellerde musluk suyu uygulanan parsellere göre bitki boyu, çiçek sayısı, kök uzunluğu, kök ağırlığı ve üst aksam ağırlığı bakımından önemli bir artış sağlanmıştır. Bitki çapı, yaprak uzunluğu, çiçek çapı ve çiçek sapı uzunluğu üzerine sulama suyu uygulamalarının etkisi istatiksel olarak önemsiz olmuştur

Reusability of Treated Wastewater in Gazania Cultivation

Industrial developments, rapid population growth and migration have caused rise in the amount of wastewater. Polluting fresh water resources, the reduction of the resources and drought have increased need fresh water need. All these factors have made effective use of fresh water resources compulsory. Treated wastewater can be reused in industrial, agricultural, forest and landscape areas. This study was conducted to determine reusability of treated wastewater in Gazania cultivation from April to October 2015. The treated wastewater used in the study was obtained from The Treatment Plant of The City of Kepez, Çanakkale. The plants of Gazania were irrigated with treated wastewater or tap water alone once a week. The experiment was set up according to randomized plot design with 3 replications. Four Gazania were planted in each replication (polyethylene pot).Variance analysis and Pearson correlation test were applied to the data obtained from the experiment. The results showed that treated wastewater is suitable for irrigation of Gazania cultivation. Plant length, flower number, root length, root weight and upper part weight of plant irrigated with treated wastewater was significantly increased in relation to the tap water plots. Irrigation treatments did not result in significant differences in plant diameter, leaf length, flower diameter and flower stem length
