Potential of Tephrosia candida for Restoration of Degraded Lands and Fuel Wood Production in Western Ethiopia
Abstract
The challenges in restoration projects are to find potential and compatible tree and shrub species to start and scale up them in a way that will have a clear effect at the landscape level while these species can help to achieve climate-smart agriculture’s “triple wins” of increasing rural incomes and biomass energy supply. This study aimed to examine the potential of Tephrosia candida as a species for degraded farmland restoration thereby to evaluate its biomass for fuel wood and local energy source. There are 3 locations where each location has 6 plots. Each plot contains 25 plants with 2m*2m spacing. Composite soil sample, plant height, DBH, survival rate, dry weight, crown cover, number of branches and time of seed collection were collected. Growth performance of Tephrosia candida was very fast which showed about 15cm height and 0.26cm diameter increment monthly, and its survival was 100% at all sites. Averagely 1.5 branches/Month recorded while crown cover increased accordingly, and on average 25 main branches and 38 secondary branches, and each shrub weigh 22.22kg on average when dried. Each Tephrosia’s crown cover was 16.25m2 on average. Analysis of composite soil sample and after 3 years of implementation soil pH increment observed in all locations, accordingly, soil pH at Diga improved from 4.89 (before) to 5.22 (3 years after implementation). We recommend Tephrosia candida for fast restoration purposes and farmland fuel wood producing species to cover the increasing fuel wood demand due to its high potential of both restoration and high biomass production.
