4.4 Land Equivalent Ratio
The cowpea plant density and varieties as well as their interaction had highly significant (p<0.01)
effect on total land equivalent ratio (Table 15). The highest total LER (1.478) was recorded when
100% cowpea, variety Kenketi was intercropped with maize whereas the lowest LER (1.027) was
recorded when 50% cowpea Bole variety intercropped with maize.
