Introduction and Evaluation of Moringa oleifera (Lam) Growth in Two Districts of Bale Zone, Oromia Region, Southeast Ethiopia

Moringa oleifera is one of the most important plants which has to be introduced, conserved and promoted for its social, economic and environmental benefits. Study was conducted aimed to introduce M. oleifera through evaluating its growth performance under the field condition of mid-altitude areas of Bale, Ethiopia. The experiment was laid-out using randomized complete block design with three replications on two locations. In the study the necessary plant growth traits namely survival rate, plant height and diameters (at breast height and root collar) were collected and analyzed by Genstat software. As to results except survival rate other growth performance traits of the studied species were statistically influenced by location in the subsequent years of monitoring period. With this, the mean value of survival rate recorded at Dello-menna was > 80% whereas at Goro it was < 80% throughout the years of study period. For plant height the recorded mean values were found between 65 cm to 370.30 cm and 58.30 to 296.70 cm range in the respective Dello-menna and Goro sites. Breast height diameter ranged from 0.747 cm to 6.533cm at Goro site and from 1.00 cm to 8.983cm at Dello-menna. In terms of root collar diameter, the values ranged from 1.933 cm to 9.867 cm and from 1.410 cm to 4.592 cm at Dello-menna and Goro sites, respectively. The values pointed that M. oleifera had showed a promising growth and development over both locations with relatively the higher performance at Dello-menna site than Goro. Therefore, the species could be demonstrated, promoted and scaled-up to the farming community of Dello-menna, Goro and other areas with similar agro-ecology. However, the nutritive value of the species in response to the studied locations has remained the focus of future research area.
