- This study aimed to assess the effect of residues of tuber extract blady grass and coco grass on soybean seed germination, plant height, dry weight of weeds, flowering period, the number of productive branches, number of seeds and seed weight of plants. The study was conducted at the Experimental Station of the Faculty of Agriculture Syiah Kuala University. This study uses a factorial completely randomized design with three replications. The first factor is the type of weed extracts with 2 levels ie Coco Grass Extract (ET) and Blady Grass extract (EA), to the second factor is the concentration (K) which consists of 5 levels, namely, (K0 = 0%), (K1 = 1.5%), (K2 = 3.0%), (K3 = 4.5%), (K4 = 6.0%). Parameters measured were seed germination, plant height, dry weight of weeds, flowering period, the number of productive branches, number of seeds and seed weight of plants. The results showed that the application of coco grass and blady grass at various concentrations inhibited germination percentage of soybean, but does not inhibit soybean flowering period, the number of productive branches, number of seeds and seed weight it stimulates the growth of soybean plants. While plant height and dry weight of weeds does not affect the application of tuber extract blady grass and coco grass. Use of extract coco grass and blady grass at a concentration 1.5% - 6.0% can increase the number of productive branches, whereas the concentration of 4.5% can increase the number of seeds and seed weight of plants can be increased at a concentration of 3.0% and 4.5%.
