<![CDATA[The study has been done to determine the effect of various types of biochar and consentration of agrodyke fertilizer on the growth of mahoni seedlings.The study used block randomized factorial design which were types of biochar (B) as the first factor, namely: soil + imperata cylindrica charcoal (B1), soil + coconut husk charcoal (B2), Soil + charcoal of sawdust (B3), and agrodyke fertilizer concentration as the second factor (A), namely: 0 g polybag-1 (A0), 25 g polybag-1 (A1), 50 g polybag-1 (A2), 75 g polybag-1 (A3) as other factors. Each treatment was replicated three times. The results showed that all types of biochar have increased in plant height and number of leaves mahoni seedlings significantly at 40, 60, and 80 days after weaning (DAW). Various concentration of Agrodyke fertilizer have affected considerably on plant height and number of leaves at 40 and 60 days after weaning (DAW) and root length at 80 days after weaning (DAW). However, there were no significant effects of types of biochar and various concentration of agrodyke fertilizer on all parameters. Biochar Soil+Charcoal Sawdust (B3) and 75 g of agrodyke fertilizer polibag-1 (A3) have produced the best growth rate of mahoni seedlings]]>
