Begashaw Mitiku*, Fikiru Bafa, Getahun Yaekob

Moringa stenopetala (Baker f.) Cufodontis is important and valuable indigenous tree species in lowland area of Ethiopia. And also important economically, socially and in the livelihood of farmers and play a key role in ecosystem resilience under climate change scenarios. In this context, the intraspecific variability in plant functional traits can be determinant to improve species fitness for specific area. Therefore, this research aimed to select better provenance for Moringa Stenopetala in the study area. The provenances of Moringa Stenopetala trees those have more common and abundantly were selected and seeds were collected and sowed in nursery. After taking appropriate nursery management germination, survival, height, RCD, branch number, above and below ground biomass of seedlings were measured in each provenance. The result shows that, Derashe, Humbo and Arbaminch-zuria provenance seeds were performed significantly higher in most of parameters like growth and biomass parameter (p=0.05). In germination rate is recorded 79% and the lowest is 26.8% from Shewarobit and Konso respectively. The growth parameter of Moringa Stenopetala show significant difference on Height and branch number. Shewarobit (12.75) shows significantly higher in mean Branch number than Benatsemay (9.75). Debase (44.05 cm), Humbug (43.48 cm) and Arbaminch (43.12 cm) height which is significantly higher than Benatsemay and Konso (31.2 cm and 30.8 cm respectively). similarly Derashe also have highly significantly differed SFW (21.03 g) RFW (16.6 g) SDW (6.9 g) RDW (5.35 g) of Moringa Stenopetala from Benatsemay (14.1 g), Metehara (10.9), Konso (3.6), and Zuria wereda (3.3) in SFW, RFW, SDW and RDW respectively. As result, to improve the germination potential selection seed source from different agro ecology is important. In spite of this we have concluded that Derashe is the seed source for the study area (meskan) for Moringa Stenopetala production from the tested provenance. Derashe recommended as seed source to produce Moringa Stenopetala seedling in meskan wereda.
