| dc.description.abstract | Faidherbia albida is an economically important forest tree species mostly used in agroforestry
systems. The species is heavily threatened with livestock feed, and studies about its regeneration
are scares. The aim of this study is to contribute to the knowledge of the species F. albida
production techniques, specifically by investigating the best pre-treatments for lifting the dormancy
of seeds and the best suited substrate and water regime to the growth and development of
seedlings. An experimental study as regards germination of seeds in the laboratory, and
assessment of growth parameters through irrigation regime and type of substrate in nursery was
carried out. A split-plot experimental design was used for seed germination rates i.e. five pre-
treatments (98% acid, 75%, 50%, 10% and H2O) with four repetitions each. Afterwards, the 98%
and 75% acid concentrations were used for the remaining study. A randomized complete block
design with three blocks and nine plots was established in a nursery to assess the growth
variables. The highest germination rates were noted with sulfuric acid doses of 98% and 75% with
respective rates of 100% and 43.75%. Significant differences in growth parameters were observed
among treatments, and the treatment that consisted of 100% potting soil and watering once every
two days showed the best growth for all assessed growth parameters (height, number of leaves
and number of spines) except for root length. This study supports that suitable pre-treatment is
needed to lift seeds dormancy in F. albida, as well as suitable substrate and water regime are
required for seedlings growth and development. | en_US |
