There was highly improved and developed in hill seeding on puddled wet soil condition for direct seeded rice with sandy type silicate application. The amount of silicate for coverage of preemerged rice seeds(approximately 10 seeds) per hill bases was 840kg/ha which would be so recommended rate for rice plant growth as well. There was no inhibition in terms of germination and seedling stand at early growing stage of the rice plant both laboratory and pot experiments. In particular there was the highest plant height in silicate covered than those of Iron-coated seed, Phyllite-coated seed and Silicate-coated seeds. In field experiment of farmer's paddy silicate covered hill seeded rice was 97.5% of seedling establishment as comparison of control, 87.5%. Rice seedling height at seedling establishment stage was 27.9cm but there was 21.2cm in the untreated control. Plant number was also higher in silicate covered seed by 27.5 per hill at 55days after sowing than that of control, 15.1 per hill. Thus a final yield was also 4.56t/ha in silicate covered rice plant which was 11% higher yield than that of control.
