Abstract: Two field experiments were conducted at Giza Agricultural Research Station during 2008 and 2009 seasons respectively. Three irrigation regimes i.e irrigation at 1.2, 1.0 and 0.8 evaporation pan coefficient were combined with four intercropping pattern of maize and soybean crop (1:1, 1:2, 2:1, and 2:2) with three replications. The main results obtained were as follows:
- Maize grain yield and its components were significantly affected by different irrigation regimes during the two growing seasons. The maximum values of maize crop were obtained with irrigation at 1.2 evaporation pan coefficient. The same trend was obtained with soybean crop.
- Maize grain yield was significantly affected under the intercropping pattern 1.2 alternated rows of soybean and maize.
- The highest soybean yield obtained under intercropping pattern 2:1 alternated rows of soybean and maize.
- Land equivalent ratio and relative crowdedness coefficient were higher under intercropping pattern 2:2 and 1:2 soybean and maize using 0.8 and 1.2 evaporation pan coefficients, respectively.
- The highest seasonal consumptive use (60.83 and 63.81 cm) and water use efficiency (0.51 and 0.47 cereal unit/cm. during the two growing seasons were obtained under the intercropping pattern 1:2 soybean/maize, respectively.
