This study was conducted to evaluate the effect of foliar fertilization and seaweed extract on floral growth characteristics and the production of corms and cormels in Freesia hybrid L. under plastic house conditions during the 2023–2024 autumn season. The study, designed as a factorial experiment with a randomized complete block design and three replicates, evaluated the effects of nano-fertilizer (NPK) at concentrations of 0, 1, and 2 mg L⁻¹, It was obtained from local markets, and seaweed extract at concentrations of 0, 1, 2, and 4 mg L⁻¹ on the floral growth and yield of corms and cormels in Freesia hybrid L. Results revealed that fertilizer (2mg/L) and seaweed extract (4mg/L) significantly improved key traits, including floral stalk diameter, flower longevity on the plant, days to the first flower opening, and corm and cormels production. These treatments achieved the highest number of corms, the greatest corm weight, and the largest corm diameter. The results of the experiment showed that the interaction between the two treatments, specifically N2M3, significantly outperformed in most floral traits and the yield of corms and cormels.
