Since herbicides are not widely used in cowpea and soybean at the present time, cultural and manual methods are important means of weed control in the tropics. Field experiments were conducted at Ibadan (in western Nigeria) to evaluate the effect of plant density, spatial arrangement and plant ty...

Because of their favourable hydrology, the small inland valleys of West Africa offer the possibility of sustainable increases in food crop production. A key component in any sustainable cropping system is the maintenance or restoration of soil fertility. This paper explores avenues for introducin...

In 1988 a field survey was conducted on soybean (Glycine max) production trials at Ayepe in Nigeria. The survey investigated yield variability, fertilizer requirements and economic returns among small farmers. It revealed that the soybean yield was low (524 kg/ha), while yield variability was ext...

High population growth and consequent pressure for food is driving agriculture towards greater intensification in West Africa. However, due to inadequate use/availability of farm manure and fertilisers, there is a continuous decline in soil fertility and overall crop productivity. This trend must...
