1.0INTRODUCTION
A forest is a large wooded area
having a thick growth of trees and other plants. The importance of trees
and shrubs to man, animal, and the environment are numerous. Trees and
other plants of the forest act as filter which cleans the air we breath.
Clean air is of great value to human health. Chacolo and Pineae (1991),
Smith (1978) and Desanto (1976).
The tern phytoremediation is a word
for the absorption of dangerous chemicals and other pollutants that are
harmful into less harmful forms, Pollard (1977). They also further
sewage farm chemicals reduce road side spills and clean water runoff
into streams. Noise pollution is known to be controlled by trees,
Chacolo and Pineace (1991). Apart from facilitating climatic
modification Muller (1998), trees are source of fuel wood, cline Cole
(1990) and shepherd (1990) land scape enhancement, Fortnnann and Riddell
(1985) one can derive useful substances from trees such as spice,
fibre, medicine which are non-timber species Smith (1992). Trees are
sources of timber. They facilitate to some extent food security and
improved nutrition, Thannan (1987). The intensity of solar energy
radiation that reaches our vicinity is controlled to some extent by
trees through solar energy blocking offered by these trees Muller
(1988). Apart from all of these trees are also known to produce oxygen,
enable wind break, carbon (iv) oxide-sequestering and Green house
effect, Go Green (2009).
Agroforestry, compound tree planting
protection plantation, aesthetic plantation, production plantation are
practices that enhance the raising of tree crops by various people and
communities. Agroforestry is a system of land use in which harvestable
trees and crops are grown among or around crops or on pasture land as
means of preserving or enhancing the productivity of the land. it is
defined as a method of farming integrating herbaceous and tree crop.
The
system has advantage over Conventional Agriculture and Forest
production method. In many ways, for example, it offers increased
productivity economic benefits, social outcomes in the ecological goods
and services provided.
Biodiversity in Agroforestry Systems is
typically higher than conventional Agricultural Systems. With two or
more interacting species in a given land area it creates a more complex
habitat that can support a wider variety of birds insects and other
animals.

ABSRACT - [ Total Page(s): 1 ]The comparative investigation of the germination and early growth of two Agroforstry tree species in the nursery was studied. Seeds of Annona recticulata were collected from a compound in Benin City. while the fruits of Annona muricata were purchased from New Benin Market. On the 6th of June 2012 a portion of land at the nursery of the department of forestry and wildlife faculty of agriculture university of Benin, Benin city Nigeria was cleared. 350 polyethene bags of smallest size that were sto ...
