Wheat, barley and finger millet as a major crop and lupine as a companion crop are food crops often traditionally grown in an intercropping in North Western Ethiopia. The experiment was conducted on intercropping of lupine (Lupinus albus L.) with wheat (Triticum aestivum), barely (Hordeum vulgar) and finger millet (Eleusine coracana) in 2009 at Adet Agricultural research station. The treatments were  sole wheat at a seed rate of 175 kg/ ha, sole barley at a seed rate of 125 kg/ ha, sole finger millet at a seed rate of 30 kg/ ha, sole lupine at a seed rate of 90 kg/ h and 25, 50 and 75% of the sole lupine seed rate combined with each full cereal seed rate to determine the effect of lupine intercropping and seed proportion on the growth, yield and yield component;  and lodging of wheat, barley and finger millet. The trial layout was a completely randomized block design with three replications. SAS software’s were used to compute the analysis of variance. Increasing in lupine seed proportion in a mixture, delay in finger millet days to heading and maturity also significantly increased. The yield and yield component of most cereals were not significantly affected when they were intercropped with lupine in all seeding ratios except finger millet plant height, harvest index and wheat total biomass yield. Hence, growing cereals in association with lupine was not showed its yield reduction and the farmer’s primary objective of maintaining a ‘full’ cereal yield was attained.  Intercropping lupine with cereals gave physical support for cereals particularly in high lupine seed proportion. The combined yield advantage was greater than one in the cases of lupine-wheat followed by lupine-finger millet mixtures at all seeding ratios. Hence, two of the best combinations which were gave higher land use efficiency are the lupine-wheat mixture at the 75:100 seeding ratio (49.4%) followed by the lupine-finger millet mixtures at the 75:100 seeding ratio (29.4%).
