Competition Indices of Intercropped Lupine (Local) and Small Cereals in Additive Series in West Gojam, North Western Ethiopia


The experiment was conducted on intercropping of lupine (Lupinus albus L.) with wheat (Triticum aestivum), barley (Hordeum vulgar) and finger millet (Eleusine coracana) in 2009 at Adet Agricultural research station, in Western Gojam. 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/ha, and an additive series of 25, 50 and 75% of the sole lupine seed rate combined with the full cereal seed rate to determine the effect of intercropping on competition (CR) among the different species, the land equivalent and area time equivalent ratios (LER and ATER); and the economic feasibility of each intercropping system(MAI) as compared with sole cropped. The experimental design was a completely randomized block with nine intercropping and four sole cropping systems in three replications. Lupine was planted in rows after establishment of main crops. JMP-5 (SAS, 2002) software’s was used to compute the analysis of variance. Partial LER of lupine was lower than LER of cereal, indicating an advantage for main crops and a disadvantage for the minor crop. Values of ATER showed 4.9%-31.3% and 11.1%-37.8% advantage in lupine-wheat and lupine-finger millet combinations, respectively, whilst lupine-barley combinations showed ATER of 54.5%-60.9% disadvantage. CR showed dominancy of wheat and barley over lupine while lupine was higher CR than finger millet. Positive MAI values were recorded in lupine-wheat and lupine-finger millet mixtures indicating that these intercropping systems were a definite yield advantage and the most profitable as compared to sole cropped. In conclusion, the lupine-finger millet mixture at the 50:100 seeding ratio and 75:100 seeding ratio; and lupine-wheat mixture at the 75:100 seeding ratio indicated a significant advantage from intercropping which was attributed to better MAI and land use efficiency (higher LER and ATER), lower CR and thereby enhanced sustainability of crop production in West Gojam, but the other socio-economic and cost of production aspects of intercropping should also be assessed especially under small scale farmers’ conditions.
