Given the large market opportunity for ginger to meet consumption, it is necessary to seek various methods of increasing production, both in terms of quality and quantity. To achieve these result, ginger production in Indonesia must be expanded, intensified, and diversified in an appropriate and economically sustainable manner. The goal of this study was to see how spacing and bokashi from various organic fertilizers affected the growth and yield of elephant ginger. This experiment used a factorial design with a randomized block design (RBD) of two factors. The first factor is the spacing (J), which has three levels: 40 cm x 20 cm spacing (J1), 40 cm x 30 cm spacing (J2), and 40 cm x 40 cm spacing (J3). The second factor is organic fertilizer bokashi (B), which is made up of four experiments: no bokashi (Bt), pig manure bokashi (Bb), cow dung bokashi (Bs), and green manure bokashi (Bh). The experimental results were statistically analyzed using analysis of variance. Results showed that the interaction effect of distances and the type of bokashi with organic fertilizer has no significant difference (P 0.05) in the growth and yield of elephant ginger. The average net assimilation rate 90-105 dap, as well as the average plant growth rate 75-90 dap were compared. The highest yield of fresh rhizomes per hectare was obtained in the at a 40 cm x 20 cm spacing.
