Abstract

The aim of this experiment was to determine the best PGPR concentration to support coffee shoot grafting. The experiment was carried out in the form of a completely randomized design (CRD) consisting of 4 treatments, namely without PGPR or control K0 (concentration 0 ml L-1 water), K1: 10 ml, L-1 water, K2: 20 ml L-1 water, and K3: 30 ml. L-1 water is given to each polybag. Each treatment had 4 replications so that there were 16 experimental units. The results showed that giving PGPR with a concentration of 30 ml L-1 of water to shoot grafts gave the best results on shoot height and shoot diameter growth. Whereas at a concentration of 10 ml.L-1 water gave the best effect on the increase in the number of leaves of coffee shoot grafting seeds.
