Effects of different ırrigation levels on european corn borer (ostrinia nubilalis (hübner)) populations

In In this study, the effects of different irrigation treatments (I100, I50, I30) on the European corn borer (Ostrinia nubilalis hübner) populations in different corn genotypes (Ada-9510, Samada-07, Ada-523, Kompozit Arifiye) were investigated. As the average, the highest yield (1582.33 kg da-1), low number of live larva + pupa per plant (2.70), tunnel length (7.73 cm) were observed in I100 x ADA-523 interaction while the lowest yield (896.00 kg da-1) was observed in I30 x Kompozit Arifiye interaction. The largest European corn borer population was observed in full irrigation (I100) and the lowest population was observed in excessive water deficit (I30) treatment. The European corn borer preferred the Kompozit Arifiye genotype. It was concluded that the genotypes should be tested under water-stressed and non-water-stressed conditions for resistance to the European corn borer and live larva and tunnel length could be used as a screening parameter

Ergene Nehri Hayat Buluyor

Bu makale Trakya Bölgesinin can damarını oluşturan ve özellikle son yıllarda kirlilik boyutunun en üst düzeye ulaştığı Ergene Nehrinde yapılan rehabilitasyon çalışmalarına dikkat çekmek üzere ortaya konulmuştur. Bu çalışmada Ergene Eylem Planı kapsamında Orman ve Su İşleri Bakanlığı öncülüğünde gerçekleştirilen ıslah çalışmalarının artarak devam ettiği ve bölgenin kalkınmasına bu tür çalışmaların son derece katkılar sağlayacağı perspektifine dayandırılarak konuyla ilgilenen tüm araştırmacıların bakış açısına katkılar sağlayacağı düşünülmüştür. Ergene Nehrinin özellikle sanayi tesislerinin atık suları ile kirletilmesi ve buna paralel olarak toprak ve su kaynakları ile birlikte nüfus ve yaşam tarzına olumsuz etkiler doğurduğu ortadadır. Ancak ilgili Bakanlığın öncülüğünde yürütülen ve bölgeyi ayağa kaldıracak bu tür çalışmanın bölgesel anlamda Trakya'ya son derece katkılara sağlayacağı aşikârdır. Özellikle Çevre ve Şehircilik Bakanlığı bölgede su kirliliğinin takibi ve sürekli izlenebilir halde tutulması konusunda ciddi adımlar atmıştır. Bu anlamda bölgede 2007-2010 yılları arasında gerçekleşen su parametreleri izleme kapsamında bazı kirlilik parametrelerinden üçte iki oranında iyileşme sağlanmıştır. Bu anlamda ileri atıksu arıtma tesisleri kurulmuş ve bir kısmının da inşaları halen devam etmektedir. Bölge için rehabilite çalışmaları hız kesmeden devam etmekte ve iki yıl içerisinde Ergene Nehrinin de yürütülen çevre kirliliği sorunlarının minimum düzeye indirgeneceği ve bu konuda somut çıktılar alınacağı Kurumlar bazında yürütülen çalışmaların neticesinde ortaya konulacaktır

Evaluation of ph changes in trout farms: a case study of niğde region, Turkey

In this study, it was aimed to periodically examine the pH changes in the water resources used for fish farming in some trout facilities operating in the Niğde region. For this purpose, the pH values of the water samples taken from the stations (pool entrance and exit) determined in the trout farms in the Niğde region were investigated. In this context, four (A, B, C, D) trout farms were determined and water samples were taken periodically (Spring period; April, Summer period; July, Autumn period, October and Winter period; January). The pH values in the water samples taken were interpreted within the scope of the "Water Pollution Control Regulation" standards. According to the results, the average pH values were determined as 7.25, 7.26, 7.19 and 7.18, in the A, B, C and D trout farms, respectively. In general, the pH values of the pool’s entrances were lower than the pH values of the pool’s exits. According to the ‘’Water Pollution Control Regulation’’ and the classes of inland water resources, it has been seen that the water resources are suitable for fish farming in terms of pH value in the examined stations
