The present study investigated the effects of composted rice husk (5 and 26; 10 g/2 kg of soil/pot) on growth and biochemical parameters of sunflower plants at the 30th and 60th day of germination. Result showed significant improvement in growth and biochemical parameters of plants as compared to control plants treated with uncomposted organic fertilizer. However, the effects vary with the microbial treatments involved in the composting of rice husk like composted with T. hamatum (JUF1), bradyrhizobium sp-II (JUR2) alone, and JUF1 in combination with Rhizobium sp-I (JUR1) were found effective in improving the shoot and root lengths, total chlorophyll, carbohydrate, crude protein, and mineral (nitrogen and phosphorus) content of sunflower plants. It indicates that composted rice husk with improved total carbohydrate and protein contents may increase the soil fertility by improving its organic content.
