Intercropping can be defined as the growth of two or more crops in the same space at the same time. This however differs from one region or zone to the other to confirm with the culture of the people. Several types of intercropping, all of which vary the temporal and spatial mixture to some degree, have been described. The degree of spatial and temporal overlap in the component crops can vary somewhat, but both requirements must be met for a cropping system to be an intercrop. Intercropping has been reported to have yield advantage over sole cropping. These advantages can occur as a result of complementary use of growth resources such as nutrients, water and light by the component crops. Intercropping with legumes is an excellent practice for controlling soil erosion and sustaining crop production.
