Results showed that the species of trees [multipurpose tree species] used as hedgerows did not significantly affect the growth and yield of gabi and camote in the first cropping but did so in the second cropping. Flemingia congesta ranks first in terms of influence to the growth and yield of gabi and camote. This is followed in descending order by Gliricidia sepium and Sesbania sesban. The significant contribution of each hedgerows species to the nutrient content of the soil particularly OM, P and K is the main reason why each hedgerow had significantly enhanced the growth and yield performance of both the alley crop and the hedgerows themselves mainly through nitrogen fixation and nutrient cycling. Gliricidia exhibited the highest overall fresh weight herbage yield at 84.87 t/ha which did not differe significantly with Flemingia's 81.28 t/ha. Sesbania has 47.66 t/ha. In terms of dry weight herbage yield, Flemingia's 28.58 t/ha significantly outyielded Gliricidia's 21.22 t/ha which in turn significantly differed with Sesbania's 14.30 t/ha.
