BACKGROUND: West Bengal is key to India's flower industry, contributing 10.61 % of total production, with marigolds valued at 63.44 thousand tonnes. To achieve good yields, many farmers heavily use chemical fertilizers and insecticides. Marigold seeds typically germinate in about 14 days, but farmers often face issues with uneven germination and poor seedling quality. MATERIALS AND METHODS: This study was conducted at ICAR-AICRP on Floriculture and Landscape Architecture, HRS, Mandouri, Bidhan Chandra Krishi Vishwavidyalaya, West Bengal, India. We synthesized nanoparticles from Tulsi, Doob grass, and Hibiscus extracts in the lab and analyzed them using XRD, SEM, FTIR, and DLS-Zeta methods. We prepared different concentrations of TiO FINDINGS: Recent trial results showed that treatments T CONCLUSION: The experiment showed that titanium dioxide (TiO
