THE ESTABLISHMENT OF NURSERY FOR TREE PLANNING IN BUEA
The Association of Biodiversity Research and Sustainable Development (ABiRSD) has established a nursery for tree planning. A nursery is a producing environment in which young tree can thrive. The aim of ABiRSD establishing this nursery is to have good supply of young trees that can be transplanted in farms, water catchments, streets/roads, schools and also in compounds of houses. This nursery is piece of land located in an area which has a good land escape, soil texture, availability of water and roads where customers and visitors can use to get to the nursery and with shades. The land, soil and polythene bags are use to develop seeds into seedlings that can be transplanted.
At present, the need to plant trees on farms and the environment is on an increase.It is imperative however, for an organization to access at the right time, in the right quantities and of high quality the trees that they want to plant. In order to meet present and future demand for planting materials, ABiRSD has established a demonstrative tree nursery. This nursery will provide income-generating opportunities, act as models for further nursery development and a demonstration site to partners and funders etc. It will provide seedlings more cheaply to planters, and can raise the particular species that local people and the community are interested in and will also help farmers to realize their produce and good earnings in a short period of time.
This nursery was established on the 12th of October in Mile 16 Buea where the piece of land was cleared and the portion for bare root and potted nurseries were tilled and shaded. Polythene bags were filled with topsoil and small gravels. The nursery is established in a piece of land with shades built to ensure that the plants are reasonably shattered from very high intensity sunlight and rainfall. Two different methods were used in this nursery for the different trees types which are; Hybrid cocoa, Bush mangoes (irvingia Gabonensis), Acacia spp.
For the Hybrid cocoa and the Acacia spp the seed method was used, in this case the seeds were first nursed in a bare root nursery. After five days they geminated and developed into seedlings. Within ten days they were then transferred into polythene bags filled with topsoil for them to acclimatize. These seedlings were transferred with their cotyledon still attached to them, their cotyledons help the seedlings to continue growing normally and healthy as if they were in their original place. This is because the cotyledon provides food and nutrients to the seedlings. These seedlings will stay in the nursery for ten weeks until it is time for them to be transplanted to the field.
the Bush mangoes two methods were used. Nursing of Bush mangoes can be done either
by the use of seeds, cuttings or seedlings from the forest. With the seeds
method, the seeds were keep in a moist and warm soil to break dormancy where
they geminated before being transferred
to the polythene bags within 12 days with their cotyledon still on them to enable
them have a high survival rate. For the seedling method, seedlings were gotten
from the forest without cotyledon and then nurse in polythene bags. The rate of
survival of these seedlings was very low because they are gotten from the
forest where their cotyledon had fallen off. This makes it difficult for the
young seedlings to pick up. That is why they can’t grow well in the polythene
bags without their cotyledon with a survival rate of 40% while those with their
cotyledons had a survival rate of 75%. A total of 1,000 trees of Acacia ssp, 300
seedlings of bush mango, and 200 seedlings of cocoa were raised for
transplanting. These plants are being continuously watered morning and evening on daily bases to ensure
fast and healthy growth of the nursing seedlings. These trees nursed in this
nursery when transplanted in the field take a shorter time/period to grow to
