Abstract
Peat soils in Malaysia is renowned for its poor chemical properties and often lead to restriction in agricultural uses. The abundance of waste in particle board and furniture industry offers a potential for producing biochar products with ability to enhance peat soil chemical properties. This study intends to evaluate the effects of different rate of rubberwood bark biochar on selected chemical properties of peat soils and growth performance of paddy variety MRIA 1, as a test crop. Results showed that application of rubberwood bark biochar at the rate of 226.80 grams (Treatment 3) significantly improve the soil pH, soil exchangeable potassium (K), calcium (Ca)and magnesium (Mg) combined with positive increment of tillers number, root length and height of paddy plant compare to other treatments. This study suggested a positive potential of rubberwood bark biochar to enhance the chemical properties of peat soils which led to good plant growth performance
