Abstract
Aims: This study aimed to standardize the dosage of hormone-based seed coating formulations to enhance germination and seedling growth in coriander seeds.
Study Design: Completely Randomized Design.
Place and Duration of Study: Department of seed science and technology, Tamil Nadu Agricultural University, Coimbatore, India. During the year of 2023-2024.
Methodology: Coriander seeds were coated with different concentrations of seed coating polymer and germination study was conducted in laboratory using rolled towel method with four replications. Data were analyzed by ANOVA with significance at p ≤ 0.05.
Results: The hormone-based seed coating formulation has recorded significantly higher germination% (69%), root length (16.75 cm), shoot length (7.9 cm), dry matter production (0.058 g/10 seedlings), Vigour Index I (1706) and II (3.9) at 10 g polymer/kg of seed and 290 mL of water.
Conclusion: Seed Coating with 10 seed coating formulation dissolved in 290 mL of water enhanced the seed germination and seedling growth.
