Biomass productivity of maize and soyabean at different plant design in intercropping system was investigated at experimental field, on chernozem luvic soil type, during 2003 and 2004. The two spatial plant designs were applied: in the strips and alternate rows. Intercropping was done according to the method of replacement series and the main goal of this approach is to change the particular number of plants of one species with another. This examination included four experimental hybrids of maize from various FAO groups of ripening (400, 500, 600, and 700) and the type of soyabean from 0 group of ripening (ZPS-015). The crops were raised in the frame of four field crop rotation (maize-wheat-spring barley+red clover-red clover). The meteorological conditions had big influence on biomass productivity in the period of experiment performance. The plant design in alternate rows was more advantageous in rainless years as it was year of 2003. Significantly higher yield occurred at intercrops comparing to monocrops of maize and soyabeans, specially in 2004. Soyabean intercrops with late matured maize hybrids gave lower above ground biomass yields. Intercrops with alternate rows was much suitable in year with low precipitation and high air temperature.
