Özet:

 This study investigated plant growth-promoting characteristics of 389 candidate bacterial isolates collected during surveys conducted in 2017 by using nitrogen fixation, phosphorus reduction, and antagonistic activities tests. Six candidate bacterial isolates were identified as a result of the tests. The identification of these species was carried out using the MALDI-TOF MS technique, which identified species as Enterobacter cloacae, E. aerogenes, Bacillus cereus, Microbacterium testaceum, Pseudomonas putida, and Acinetobacter calcoaceticus. Pot and field trials were conducted using different combinations of these isolates. All isolates were used in the pot experiment, whereas isolates with the highest antagonistic activity and their combinations were used in the field trials. The pot trials were conducted using a randomized block design with five replications, while the field trials were conducted using a randomized complete block design with ten replications. The effects of these isolates on the yield of healthy pepper plants were investigated. Data relating to plant height, root length, stem diameter, number of fruits, plant fresh and dry weight, and root fresh and dry weight were collected. Results of the pot experiment revealed that combinations of B. cereus  P. putida and P. putida  A. calcoaceticus resulted in 15 higher yield compared to the control. Similarly, field trials indicated that P. putida improved the values of investigated traits by 12.3-37.2. Pseudomonas putida is considered beneficial for future research based on the results of this study.

 Bu çalışmada, 2017 yılında yapılan sürveyler sonucunda toplanan 389 aday bakteri izolatının bitki büyümesini teşvik edici özellikleri araştırılmıştır. Elde edilen izolatların bitki gelişimini teşvik etme özelliklerini belirlemek amacıyla azotu bağlama, fosforu indirgeme ve antagonistik etki testleri yapılmıştır. Testler sonucunda altı adet aday bakteri izolatı belirlenmiştir. Bu türler MALDİ-TOF MS tekniği ile Enterobacter cloacae, Enterobacter aerogenes, Bacillus cereus, Microbacterium testaceum, Pseudomonas putida ve Acinetobacter calcoaceticus bakterileri olduğu tanılanmıştır. Saksı ve tarla denemeleri, bu izolatların farklı kombinasyonları kullanılarak yürütülmüştür. Saksı denemesinde tüm izolatlar kullanılırken, tarla denemesinde en yüksek antagonistik etkiye sahip izolatlar ve bunların kombinasyonları kullanılmıştır. Saksı denemeleri tesadüf parselleri deneme desenine göre 5 tekerrür olarak yürütülmüştür. Tarla denemeleri ise tesadüf blokları deneme desenine göre 10 tekerrürlü yürütülmüştür. Bu izolatların sağlıklı biber bitkisinin verim değerlerine etkileri araştırılmıştır. Saksı çalışması ve devamında yürütülen tarla çalışmasında bitki boyu, kök uzunluğu, gövde çapı, meyve sayısı, bitki yaş ağırlığı, bitki kuru ağırlığı, kök yaş ağırlığı ve kök kuru ağırlığı gibi parametreler ölçülmüştür. Sonuç olarak sera denemelerinde B. cereus  P. putida ile P. putida  A. calcoaceticus bakterilerin ikili kombinasyon uygulamalarında kontrole göre 15 daha fazla verim elde edilmiştir. Tarla uygulamalarında ise P. putida uygulaması değerlendirmeye alınan bitki parametrelerinde 12,3-37,2 arasında değişen oranlarda artışı sağlamıştır. Çalışma sonuçlarına göre özellikle Pseudomonas putida ile ileriye dönük çalışmaların yapılmasının yararlı olacağı düşünülmektedir.
