Abstract

A field experiment was conducted in (juwaba) Arural 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 of mung bean crop, maize varieties ( bhooth 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, cultivars were arranged in main plote the main plots and the secondary plots occupies (the intercropping systems). The results showed that the characters of growth and yield of the mungbean increased whenever the density of the maize crop grown with it increased, The system of intercropping 1:2 gave the highest values with a significant difference in the height of plant which gave 54.98 cm in the spring and autumn seasons compared to the more densities treatments of the maize crop, It also was superior in leaf area in the autumn season by giving 4447 cm2,the number of branches per plant in the autumn season which gave 15.66 branch.plant-1 and also gave The highest number of pods in the plant 17.62 pods.plant-1 in the autumn season In terms of grain yield, which is the most important indicator, the intercropping system 1:1 was the best which gave the highest value 1177 kg.ha-1.The effect of maize cultivars in the growth and yield of the mungbean was different according maize cultivars. The yield of the mungbean which cultivated with the French cultivar gave the highest yield 1280 kg.ha-1 in the spring season. while the yield of mungbean that cultivated with 5012 cultivar gave 1138kg.ha-1, There were significant differences between the interaction treatments in most of the studied characters.
