Abstract

The study evaluated the effects of different doses of Azospirillum lipoferum (AzL) and seaweed extract (DY) applications on the growth and development parameters of eggplant seedlings. The DY-3 dose provided the highest values for stem height, fresh leaf weight, and total aboveground fresh weight. AzL applications at low and medium doses showed positive effects, whereas the high dose negatively impacted growth. AzL+DY combinations exhibited positive effects on stem and leaf parameters, with the best results recorded at the AzL+DY-3 dose. The findings suggest that seaweed extract supports growth through phytohormones and nutrients, while Azospirillum promotes root system development. The combined use of Azospirillum and seaweed extract offers an effective approach for sustainable seedling production as an alternative to chemical inputs. Further research is recommended to optimize application doses and methods to enhance the efficacy of biostimulants.

Özet

Patlıcan fidelerinde Azospirillum lipoferum (AzL) ve deniz yosunu özütü (DY) uygulamalarının farklı dozlarda büyüme ve gelişim parametreleri üzerindeki etkilerini değerlendirmiştir. DY-3 dozu, gövde boyu, yaprak yaş ağırlığı ve toplam yeşil aksam yaş ağırlığında en yüksek değerleri sağlamıştır. AzL uygulamalarında düşük ve orta dozlar olumlu etkiler gösterirken, yüksek doz büyümeyi olumsuz etkilemiştir. AzL+DY kombinasyonları, gövde ve yaprak parametrelerinde pozitif etkiler sunmuş, en iyi sonuçlar AzL+DY-3 dozunda kaydedilmiştir. Sonuçlar, deniz yosunu özütünün fitohormonlar ve besin maddeleriyle büyümeyi desteklediğini, Azospirillum’un ise kök sistemi gelişimini teşvik ettiğini göstermiştir. Azospirillum ve deniz yosununun birlikte kullanımı, kimyasal girdilere alternatif olarak sürdürülebilir fidecilik için etkili bir yöntem sunmaktadır. Biyostimülanların etkinliğini artırmak için uygulama dozları ve yöntemlerine yönelik daha fazla araştırma önerilmektedir.
