The studies consisted of five intercropping systems (maize sole, cowpeas sole, mungbean sole, maize + cowpeas and maize + mungbean). The results regarding LER showed that maize + cowpeas intercrop average of two locations was 1.29 indicating 29 percent yield advantage which is also biological efficient system. The maize + mungbean indicating 4 percent yield advantage. However, the economic analysis gave a different results which showed that mungbean sole crop gain highest BCR value (return per rupee invested i.e. Rs. 4.82) followed by cowpeas sole crop (Rs. 4.13). It is concluded that apart from biological efficient different economic indices should be computed for comparison and final recommendation for wide spread adoption.]]>Andrews, D.J. and A.H.
