C: control, no bacterial treatments applied; Tr1: treatment 1, soaking sweet potato secondary cuttings in bacterial suspension before planting; Tr2: treatment 2; same treatment as Tr1 with an additional treatment of leaves; Tr3: treatment 3, same treatment as Tr2 with an additional secondary treatment of leaves.
