A field study was conducted on chernozem soil type at experimental field of Maize Research Institute Zemun Polje, Belgrade (Serbia) during three-year period 2003-2005. This examination included three experimental hybrids of maize from various FAO groups of ripening (500, 600, and 700) and the type of soya bean from 2nd group of ripening (Nena). Maize and soybean were grown in pure stands and three combinations of intercrops (alternate-row and in strip intercropping). Additive design was used for creating of intercrop variants. There was investigated the grain yield of maize and soya bean in the intercropping, and compared with the yield of the monocrops. Comparing with the intercropping production of monocrops production of maize and soya bean, with the index LER, the results obtained indicate that there are more intercropping production, especially 2004. The three-year average, the increase of grain yield in intercropping in relation to monocrops of maize and soya bean was 45% in the strip, or 49% in alternate rows. Intra-species the intensity of competition is higher in the strip and in the pattern arrangement of the resulting lower relative grain yield, primarily due to lower maize yield.
