Estimation of browse biomass of Ficus thonningii, an indigenous multipurpose fodder tree in northern Ethiopia

摘要: Ficus thonningii is a multipurpose browse tree in northern Ethiopia. Despite its importance, techniques for quantifying browsable biomass have not been developed. To develop best-estimation equations, the dendrometric parameters total height (H), crown (CH), diameter (CD), at stump (DSH), breast (DBH), depth (CDp), area (CA) and volume (CV) were measured from 12 sampled trees comprising three age ranges. Leaves edible twigs of clipped, oven dried, weighed recorded as dry weight (DW). Regression analysis multicollinearity test employed to remove non-significant predictors DW. Results showed that only CV, CA, CD, CDp DSH strong correlation with There was high collinearity between CD CA CV. However, CV had higher DW than their counterparts, which suggested use model. Therefore, best allometric equation was: D...
