Boron (B) is an essential micronutrient for rice growth and development. This experiment was conducted to explore the potential of seed coating with B for improving the germination and early seedling growth of fine grain rice. Seeds of two fine grain aromatic rice cultivars viz. Super Basmati and Shaheen Basmati were coated with B at 1.0, 1.5, 2, 2.5 and 3.0 g B kg -1 seed; while seeds without coating were taken as control. Boron seed coating with 1-2 g B kg -1 seed improved the germination energy, germination index and final germination percentage in both the tested cultivars. None of seed coating treatments improve the radicle length and leaf score; however plumule length, number of secondary roots and seedling fresh and dry weights were improved by seed coating with 2 g B kg -1 seed in both cultivars. Increasing B concentration beyond 2 g B kg -1 seed was toxic for seeds of both cultivars. In conclusion, rice seeds may be coated with B at 2 g B kg -1 seed to improve the germination and early seedling growth of fine grain aromatic rice.
