Abstract

A laboratory experiment on seed priming in rice with K₂SO₄ was conducted with four genotypes (Pusa Basmati-1, Basmati-385, Saket-4 and IR-36) and six concentrations of K₂SO₄ salt (0.5%, 1.0%, 2.0%, 4.0%, 8.0% and 16.0%) for 5 min, 30 min and 24 h durations. Data on the following quality parameters viz., root length, no. of roots/seedling, shoot length, fresh and dry weights of seedling and germination were recorded. Seed priming with K₂SO₄ for 24h was effective in enhancing germination and seedling growth. Significant differences were observed between genotypes due to K₂SO₄ priming. Among the four cultivars of rice tested, IR-36 was highly responsive to K₂SO₄ salt particularly at 1.0% concentration.
