Analysis performed on more than 60 samples f 10 different paddy varieties showed 21.33% o f the rough rice comprised rice husk, while 13% o f the husk constituted rice husk ash. The nutrient content o f rice husk ash was 80.26% silica, 0.38% phosphorus, 1.28% potassium, 0.21% magnesium and 0.56% calcium. Statistically, nutrient composition is significantly influenced by varietal differences. As a potential material for fertilizer use, the estimates o f total nutrient supplementation available from rice husk ash per annum are discussed.
