A field experiment was conducted in the (Juwaba) Arund area of Ramadi city in the spring and autumn seasons 2017.

To study the effect of intercropping systems and maize varieties on the yield and its components and the quality characters of maize crop, maize varieties (booth 106, 5018, 5012 and French cultivar) were used.

The experiment was carried out according to the design of (RCBD) and in the order of the split plot, cultivar wear arranged in Maine poke the main plots and the secondary plots occupies (the intercropping systems).

While the cultivars, The French cultivar was superior in spring season in seed yield which gave the highest value 7.99 ton ha-1, while the cultivar 5018 was superior in the autumn season by giving the highest grain yield was 11.48 ton ha-1, while the qualitative characters, sole crop for maize was excellence in the percentage of oil on the rest of the farming systems in the autumn season only gave higher mean about 4.74% , while the intercropping system 1: 2 exceeded the in percentage of protein in seeds about 10.32% in spring and autumn seasons.
