Abstract:

The study was conducted to investigate the effects of Acacia tortilistree in farmland on some selected soil physicochemical properties, and maize grain yield in Gursumdistrict, Eastern Hararghe, Oromia, Ethiopia. For the experiment of soil physicochemical properties, two factors: distance from tree trunk with three levels (under canopy, edge of canopy and out of canopy) and soil depth with two levels (0-20cm and 20–40cm depth) with factorial arrangement in RCBD replicated six times were employed. For maize yield only one factor; distance from tree trunk with three levels ((under canopy, edge of canopy and out of canopy) for maize yield in RCBD replicated six times were used. The result showed that, for soil physical properties values of soil bulk density under canopies were significantly lower than out of canopy distance (p
