Özet:

 This study aimed to investigate the effects of Azospirillum lipoferum AzL and seaweed Seaweed treatments on growth parameters and chlorophyll content of watermelon seedlings and aimed to contribute to sustainable seedling practices in Turkey. The experiment was conducted at Van Yuzuncu Yil University, Faculty of Agriculture, under controlled environmental conditions, using the Crimson Sweet watermelon cultivar. A total of 10 different treatment groups three doses and combinations of AzL and DY and control group were evaluated. The results indicated that a low dose of Azospirillum 1.25 mL L-1 enhanced parameters such as root fresh weight and chlorophyll content, while high doses appeared to negatively affect growth. The high dose of seaweed extract 5 mL L-1 provided the best results in leaf number, leaf fresh and dry weight and chlorophyll content. Combination treatments, especially at medium doses 2.5 mL L-1, showed synergistic effects on photosynthesis-related parameters including chlorophyll content and leaf fresh weight. The study reveals that the combination of the capacity of Azospirillum to enhance nutrient uptake in the rhizosphere and the biologically active components of seaweed promotes plant growth. Future studies should focus on optimizing these biostimulants based on dose, application method, and environmental conditions, as well as investigating their molecular effects and conducting field trials and economic analyses. The results obtained from this study are thought to contribute to the widespread adoption of sustainable seedling practices.

 Azospirillum lipoferum AzL ve deniz yosunu DY uygulamalarının karpuz fidelerinin büyüme parametreleri ve klorofil içeriği üzerindeki etkilerini incelemek amacıyla yürütülen bu çalışma, Türkiyedeki sürdürülebilir fidecilik uygulamalarına katkı sağlamayı hedeflemiştir. Araştırma, Van Yüzüncü Yıl Üniversitesi, Ziraat Fakültesinde kontrollü çevre koşullarında gerçekleştirilmiş ve Crimson Sweet karpuz çeşidi kullanılmıştır. Toplamda 10 farklı uygulama grubu AzL ve DYnin üçer dozu ile kombinasyonları ve kontrol grubu değerlendirilmiştir. Sonuçlar, Azospirillumun düşük dozunun 1.25 mL L-1 kök yaş ağırlığı ve klorofil miktarı gibi parametrelerde daha yüksek performans sağladığını, ancak yüksek dozlarda büyümeyi olumsuz etkileyebileceğini göstermiştir. Deniz yosunu özünün yüksek dozu 5 mL L-1, yaprak sayısı, yaprak yaş ve kuru ağırlığı ile klorofil miktarında en iyi sonuçları sağlamıştır. Kombinasyon uygulamaları, özellikle orta dozlarda 2.5 mL L-1, klorofil miktarı ve yaprak yaş ağırlığı gibi fotosentezle ilişkili parametrelerde sinerjik etkiler göstermiştir. Çalışma, Azospirillumun rizosferde besin alımını artırma kapasitesi ile deniz yosununun biyolojik aktif bileşenlerinin birleşiminin bitki gelişimini desteklediğini ortaya koymaktadır. Gelecekte bu biyostimülantların; doz, yöntem ve çevresel koşullara göre optimize edilmesi, etkilerinin moleküler düzeyde incelenmesi ve saha denemeleri ile ekonomik analizlerinin yapılması önerilmektedir. Bu çalışmadan elde edilen sonuçların, sürdürülebilir fidecilik uygulamalarının yaygınlaşmasına katkı sağlayabileceği düşünülmektedir.
