In this report, we discussed the efficient usage of the developed practical devices by investigating the operation efficiency in the cleft grafting process of eggplant. Time required to graft one seedling was from 60 to 70% of the manual operation, and the grafting success ratio was equal or higher than that of the manual operation. It became clear that the practical devices ware applicable to the conventional grafting system. Group work, where each worker was allotted the portion of the grafting processes, had the advantage in the efficient usage of the devices compared with one-person operation. It also had the advantage in higher operation efficiency. By using the practical devices, the operation efficiency could remarkably be improve and grafting time was shortened in half.
