ABSTRACT The growth of farmer-managed tree seedlings (FMTS) is pramount to impact agroforestry technology adoption. This paper presents the performances of FMTS of 3 avocado varieties (Hass, Ettinger and Fuerte) and one papaya variety (Solo) in three districts (Dugda, Adamitulu, and Lome). Thirty-six trials were established (12 trials per district) in 36 homsteads selected purposively. Each homestead was considered as a block in RCBD. Watering frequency was found higher in Dugda than the remaining districts. Seedling survival exhibited significant differences (α<0.05) among varieties with in and across districts. Survival of Solo papaya was significantly higher (α<0.05) at Dugda (91%) than in Adamitulu and Lome. Hass avocado reveled significantlly higher survival (91%) at Dugda than Ettinger and Fuerte across districs. Significant differences in Plot Volume Index (PVI, an integrative growth measurement) among varieties within and across districts indicated that seedling growth was influenced by variety, planting site and, watering fequency. PVI of Hass at Dugda was significantly higher (by 35% and 110%) than that of Ettinger and Fuerte, respectively. PVI of Solo Papaya at Dugda was significantly higher (α<0.05). Hass was found promising avocado variety for planting locations considered, and frequent watering was found crucial for good growth of the tested plant varieties.
