ABSTRACT
Increase the vegetative growth of arabica coffee, needs to be innovation in the fertilizer used. The latest innovation in fertilizer manufacturing technology is to form endophytic bacterial cell cultures into microgranules using encapsulation techniques. The application of microgranules to Arabica coffee plants is carried out using the factorial CRD (Completely Randomized Design) method consisting of 2 factors, 16 treatments, 2 replications. The treatment of seed immersion time with the addition of endophytic bacterial suspension consists of: B0: without immersion, B1: 6.5 Hours; B1: 7.5 Hours; B3: 8.5 Hours. The addition of endophytic bacterial microgranule consisted of I0: 0 gr; I1: 5 grams; I2: 10 grams; I3: 15 grams. The data obtained were analyzed using variance analysis. The results of the variance analysis were continued with multiple distance tests. Isolation of coffee roots and stems obtained 8 isolates of endophytic bacteria. From the results of the research, the growth of coffee in suspension immersion and microgranule administration was very influential, the best plant height was in treatment B2 (14.20 cm) and the lowest treatment was in B0 (9.96 cm). While the diameter of the best treatment was in B3 (1.66 mm) and the lowest treatment was in B0 (1.39 mm).
