Abstract
This study was conducted to evaluate the effects of liquid vermicompost (LVC), salicylic acid (SA), and proline (PR) applications on the growth and development of fresh onion (Allium cepa L.). The research was carried out in the unheated glass greenhouse of Van Yüzüncü Yıl University using a randomized block experimental design. Parameters such as plant height, root length, stem diameter, leaf number, total fresh and dry weight, and SPAD value were examined. The experimental results revealed statistically significant differences among the treatments (p˂0.05). The SSG1+SA1+PR1 combination exhibited the highest values in terms of plant height (29.81 cm), total fresh weight (187.33 g), and total dry weight (22.68 g). However, its SPAD value (60.13) was lower compared to individual applications. The positive effects of proline on SPAD value (67.70) and root length (14.64 cm) in individual applications were not sufficiently expressed in combinations. Additionally, high doses of SA and SSG inhibited growth in certain combinations. Cluster analysis and PCA results indicated that while synergistic effects were observed, antagonistic interactions also emerged. In conclusion, the application of 2% SSG + 0.1 mM SA + 50 ppm PR (SSG1+SA1+PR1) was determined to be the most suitable dose for enhancing plant growth and yield. However, further research is needed to optimize the doses and assess their applicability under open-field conditions.
