Abstract

A study was conducted to evaluate adaptation and growth performance of five multipurpose tree species at Erer Dodota Kebele, Harari Regional State for three years (June 2016 - June 2019). Five multipurpose tree species (Sesbania sesban, Moringa oliefera, Gravilea robusta, Azadarichta indica and Leuceana leucocephala) were compared in randomized complete block design with three replications. Data on growth parameters, diameter, and plant height and survival rate were measured and recorded at interval of three months. Results revealed that there were highly significant (p

Highlights

Eastern Ethiopian high land is well known by vegetation cover and most of the surrounding area is covered by forests comprised of a rich mixture of woody species [1]
Diameter growth trend shows that the highest root collar diameter was recorded for Azadarichta indica followed by Moringa oliefera, Sesbania sesban and Leuceana leucocephala but the lowest root collar diameter was recorded for Gravilea robusta at the study area condition
The results indicated that there were significant effect among tree species for plant height, survival rate, root collar diameter and diameter at breast height

Summary

Introduction

Eastern Ethiopian high land is well known by vegetation cover and most of the surrounding area is covered by forests comprised of a rich mixture of woody species [1]. In spite of the importance of forest ecosystem to the livelihoods of the people in the area, the forest is dwindling from time to time due to high exploitation of woody and non-woody products. Rapid deforestation caused by an escalating demand for fuel wood expansion for agriculture has brought an ever-increasing pressure on native woodland species [2]. If no remedial action is taken, this will cause severe impact on agricultural productivity leading to energy poverty and environmental degradation. Biomass energy constitutes 88.7% of all energy consumed in Ethiopia which is mainly derived from the woody biomass resources (forests, woodlands, shrub lands, planted trees, agro forests). Agro forestry system has much potential for supplying fodder, poles, farm equipment, fuel wood and agricultural improvements [1]
