Effect of Tree Canopy Cover on Grass Species in Nigerian Guinea Savanna
The effect of tree canopy cover on the yield, crude protein (CP), and fibre content of grass species in the Nigerian Guinea savanna was studied. The following grass species, Andropogon gayanus, Hyparrhenia involucrata, ...
Effect of tree canopy cover on the yield, crude protein and fibre content of forb species in Nigerian Guinea savanna
The relationship between tree canopy cover and forb species in savanna was investigated by examining the effect of tree canopy cover on the yield, crude protein, fibre and lignin content of forb species. The yield of some ...
Nitrogen Concentration in the Major Grasses of the Derived and Guinea Savanna Zones of Nigeria in Relation to Season and Site
The concentration of total Kjeldahl N in above- and below-ground grass samples was monitored at five Nigerian savanna sites over 3 years. Significant variation, even in the same species, was found from plot to plot, with ...
Nigerian Man and Biosphere Research Plots in Guinea Savanna: Floristics and Structure of the Vegetation
A study was made of the vegetation of three plots used in the Nigerian Man and Biosphere Research Programme for Savanna Studies. The aim is to provide detailed information on the vegetation of the plots which may possibly ...
Primary Production in the Savanna
It is emphasized that there is a dearth of information on primary production in the savanna in spite of savanna occupying nearly 80% of the West African land surface. Known values from the literature of annual primary ...
The Effects of Tree Canopy Cover on Soil Fertility in a Nigerian Savanna
The effect of tree canopy cover on soil properties was studied over three periods: mid-dry season (January), mid-growth period (August) and peak-growth period (October) in three 1 ha plots in savanna of north-west Nigeria. ...
