Decrease in the number and biomass of weeds, especially of perennial ones, is one of the advantages of intrecropping. The results obtained in the first two years of investigation (2003 and 2004) show that the number of perennial weeds and their fresh weight were lower in both plant arrangement patterns in intercrops than in maize and soybean monocrops. However, in 2005, the arrangement pattern in strips was the only efficiency pattern in terms of weed fresh weight per area unit. In the dry year of 2003, the plant arrangement pattern in alternate rows was advantageous, while the pattern in strips was more efficient in 2004 and 2005. Intercropping affected maize more favourable than soybean crops, in which the positive effect was most evident in 2005, especially in strips, and it mainly related to the number of weed plants per species. The longer the growing season of studied maize hybrids was, the less intensive was weed distribution in monocrops. Such a regularity was expressed in intercrops in 2003 in both plant arrangement patterns, while in 2004 and 2005 intercropping in strips was efficient with late maturity hybrids, especially in relation to weed fresh weight.
