ABSTRACT
Evaluation of plant species
useful in soil erosion control in two selected gully sites at Paradise Akanu in
Ohafia Local Government Area of Abia State, was studied from March through
November 2005. A total of lo plant species consisting of 5 grasses and 5 trees
were used in the study. They were planted at the base and sides of the gullies
and were replicated three times in each of the gully site. A Randomized
Complete Block Design was used. Seeds of tree species w^tplanted at an
espacement of 0.25m x 0.25rn. The end of the planting, iron poles were stocked
down at the ground of the gully sites at an espacement of 1.0m x 1.0m to enable
the measurement of the quantity of soil removed fortnightly. All seeds
germinated between 4 and 20 days. All grasses sprouted within 2 and 5 days.
Perotis indica was very efficient in binding the soil as it produces roots at
every node. It also lies nearly horizontal on the ground. Vertiver ziflqyjoides
was also good but dose not cover the exposed soil quickly as Perotis indica.
Panicum maximum binds the soil but the total area covered was small. Pennigetum
purpqreum was effective. Ageratum conozyoides germinated early but some were
carried away by rainwater and they died early and had the least cover. The tree
seedlings were good in controlling erosion but they have not formed enough
branches to cover the exposed soil. Miiicia exceisa was very efficient because
of its broad leaves and Irvingia gqbonensis because of its architecture. A
total of 1.1 lm3 of soil was removed within the eight months of the study. The
highest quantity was removed during the month of July and June. It is
recommended that a combination of grasses and trees such as Perotis indica,
Vertiver zinzyioides and Miiicia exceisa be used in controlling erosion in
Southeastern Nigeria. There is no significant different between the quantities
of soil removed from the two erosion sites.
