Abstract:

 This study was carried out to determine the effects of different water levels and nitrogen doses on the potato beetle and natural enemies. In 2019 and 2020, the experiment was carried out on a total of 18 plots in 3 replicates according to the randomized completely block designs at the experimental area of East Anatolian Agricultural Research Institute, Soil Water Campus. It consisted of irrigation levels in the main plots S1: full irrigation, S2: 70 of the irrigation water given to S1 subject, and nitrogen doses in the sub-plots G1: 7 kgda N, G2: 14 kgda N, G3: 28 kgda N. The average population density of Colorado potato beetle in water restricted application S2 was 0.40 individualsplant, 0.47 individualsplant in full irrigation application S1, 0.32 individualsplant in 7 kgda nitrogen application, 0.46 individualsplant in 14 kgda nitrogen application, and 0.52 individualsplant in 28 kgda nitrogen application. As a result, it was concluded that high nitrogen applications are not suitable for Colorado potato beetle control.

 Bu çalışmada; farklı su düzeyleri ve azot dozlarının patates böceği ve doğal düşmanlar üzerine etkisini belirlemek amaçlanmıştır. Araştırma, 2019 ve 2020 yıllarında, Doğu Anadolu Tarımsal Araştırma Enstitüsü, Toprak Su Yerleşkesinde, tesadüf bloklarında bölünmüş parseller deneme desenine göre üç tekrarlı olarak toplam 18 parselde yürütülmüştür. Ana parsellerde sulama düzeyleri S1: Tam sulama, S2: S1 uygulamasına verilen sulama suyunun 70i, alt parsellerde ise azot dozları G1: 7 kgda N, G2: 14 kgda N, G3: 28 kgda N yer almıştır. Ortalama patates böceği ergin popülasyon yoğunluğu su kısıtı uygulamasında S2 0,40 bireybitki, tam sulama uygulamasında S1 0,47 bireybitki, 7 kgda azot uygulamasında 0,32 bireybitki, 14 kgda azot uygulamasında 0,46 bireybitki ve 28 kgda azot uygulamasında 0,52 bireybitki olmuştur. Elde edilen sonuçlar yapılan istatistiksel analiz sonucunda yüksek azot uygulamalarının patates böceğinin kontrolü bakımından uygun olmadığı sonucunu ortaya koymuştur.
