A field experiment was carried out at Sides Agricultural Research Station in Beni-Suif Governorate during 2015 and 2016 seasons to study the effect of some intercropping patterns for basil by100% + maize (25%, 33% or 50%) and three maize cultivars (S.C. 167, T.W.C. 314 and Giza 2) on growth, yield and yield components of basil and maize. A split-plots design with three replications was used. The main plots were devoted to the previous three maize cultivars, whereas, the sub-plots were allocated to the intercropping patterns of maize cultivars with basil. The main obvious results of this study can be summarized as follows. The results revealed that S.C. 167 maize hybrid gave the highest values for yield and yield components characters, while Giza 2 cultivar gave the lowest values in both season. Under interaction, when maize plant density with basil was increased from 25, 33 up to 50 %, grain yield and components of maize recorded gradually increase, as well as maize grain yield had the same trend. The yield of basil and its components as well as essential oil percentage were significantly affected by the intercropping of maize with it, whereas the decrease was evident when intercropped the S.C. 167 followed by T.W.C. 314 and Giza 2. Maximum values of land equivalent ratio (LER) (1.31) when intercropped G. 2 with basil by 100% basil + 50% maize and relative crowding coefficients (10.83 and 15.66) were observed with G. 2 when intercropped by 25% with 100% basil in both seasons, respectively. The data indicated that maize was the dominate and basil was the dominated in all patterns. The return showed that intercropping maize with basil in most treatments was lower compared to solid maize or solid basil planting. The highest net return were LE 14644 when intercropped G. 2 with basil by 100% basil + 25% maize whereas the different between the highest and lower value was LE 6110 in combined data across two seasons.
