Özet:

 This study was conducted to investigate the effects of proline PR, an amino acid, and seaweed SW, which has biostimulant properties, on the growth and development of green onion Allium cepa L. plants. The experiment was conducted in an unheated glass greenhouse at Van Yüzüncü Yıl University using a randomized block experimental design. Key growth parameters including plant height, root length, stem diameter, number of leaves, total fresh and dry weight, and SPAD value were assessed. The results revealed that the highest plant height 29.24 cm was recorded in the PR2 SW1 100 ppm proline  3 gL seaweed treatment, demonstrating a significant synergistic effect compared to individual applications p  0.001. The longest root length was observed in the PR1 SW2 50 ppm proline  5 gL seaweed treatment 17.02 cm, suggesting enhanced root development. The highest stem diameter 5.40 mm was measured in the SW2 5 gL seaweed treatment. Regarding biomass accumulation, the PR1 SW2 treatment resulted in the highest total fresh weight 172.67 g, while the control group had the lowest 144.00 g. The highest dry weight 22.91 g was recorded in the PR2 SW1 treatment. For chlorophyll content, the PR2 SW1 treatment yielded the highest SPAD value 69.53, though the differences were not statistically significant p  0.1467. These findings suggest that proline and seaweed applications can enhance growth and yield in green onion production, with the PR2 SW1 combination providing the most favorable results. However, further studies are needed to determine the optimal application rates, assess their effectiveness under different environmental conditions, and evaluate their long-term impact on agricultural production.
