The experiment was done with six treatments. T1- recommended chemical fertilizer, T2- Rice straw (1.0 t/ha), T3-Rice husk biochar (1.0 t/ha), T4-Rice straw (0.5 t/ha) + Rice husk biochar (0.5 t/ha), T5-Rice straw (1.0 t/ha) + Rice husk biochar (0.5 t/ha) and T6-Rice straw (1.0 t/ha) + Rice husk biochar (1.0 t/ha). Recommended chemical fertilizer was incorporated to all the treatments. During the vegetative periods, the growth parameters were recorded and finally yield analysis was done. Rice plants treated in rice straw (1.0 t/ha) and husk biochar (1.0 t/ha) along with chemical fertilizer had significantly (P<0.05) higher mean values of leaf area (185.93 cm <sup>2 </sup>), number of tillers (4.0), number of roots per plant ( </span> <span lang="tr" style="font-family:Arial, ’sans-serif’;" xml:lang="tr">105.33) and also dry weights of shoots (5.15 g) and roots (4.27 g) per plant </span> <span lang="tr" style="font-family:Arial, ’sans-serif’;" xml:lang="tr"> when comparing chemical fertilizer alone.
