Abstract
This study aimed to determine the effects from biochar types application and dolomite-coffee compost application on characteristic of soybean germination. This study used factorial randomized design with two factors and two replications. The biochar types application that were applied were no biochar, rice husk biochar, rice straw biochar. Second factor was dolomite-coffee compost application such as control, dolomite 500 kg/ha, coffee compost 10 ton/ha, dolomite 500 kg/ha + coffee compost 10 ton/ha. The parameters observed in this research were root length, shoot length, root volume, root and shoot dry weight. Result of study indicated that rice straw biochar had the highest value of soybean germination like shoot length, root volume, root and shoot dry weight compared with other biochar types application. The highest value of root volume and root dry weight were found from dolomite application. Combination rice straw biochar with dolomite application showed the highest value of soybean germination.
