Intercropping has benefited the global agricultural sector in several ways. It is a critical farming practice for long-term productivity, agro-ecological improvement, land management and land use. It is a well-known method to increase soil health and crop productivity. Mixtures of cereals and legumes are used extensively for forage production. Mix between maize (Zea mays) and soya bean (Glycine max L.) were used to investigate on intercropping effect on moisture and temperature of soil related to yield of maize. The experiment was carried out as randomized complete block design with four replications. The results showed that intercropping systems had non-significant effect on yield of maize. But it affected to soil conditions especially between plant; reduce soil temperature rang about (0.3– 8 ?) effected by treatment of soya bean sowing methods (W2) for both seasons. The percentage of soil moisture content was increased about (1-18 %), treatment W2. It was because increased of percentage of canopy cover fraction by soya bean covered.so the conditions area of maize was adaptation to give chance for increase irrigation intervals of maize without make stress.
