In farming year 2008, a test as split factorial plan in form of fully random block was carried out in three frequencies at the Resarch Farm of Aboureyhan Pardis of Tehran University to study the effects of different irrigation regimes (water tension) and biologic fertilizer, consisting a mixture containing (2 phosphate solvent microorganisms) and various amounts of phosphate fertilizers on some morphological characteristics and performance of hybrid SC704 maize seeds. The stress treatment (low irrigation) in three levels(a) consisting 75, 100 and 125 mm accumulation evaporation, the evaporation dish class A was used as the main factor; the minor factors included a combination biologic fertilizers in two levels(b) (use or not use) along with phosphate chemical fertilities from triple super phosphate source in 4 levels(c), including no use of fertilizer (0), 75, 150 and 225 kg/ha as factorial in secondary in field experimental plot. In this test, the process of changes in dry weight of stem and leaves, height, chlorophyll amount and the seeds and biologic performances were studied. By taking distance from optimized humidity and nutritional conditions, significant decrease in the characteristics subject of study was observed. The destructive conditions of height stress and amount of chlorophyll in the leave in 125mm evaporation treatment (severe stress) was seriously reduced. In normal humidity conditions, using biologic fertilizer and consuming 150 kg/ha, the triple super phosphate fertilizer increased seeds performance significantly and the effect of biologic fertilizer was in a way that by producing organic acids and phosphates enzyme in insoluble phosphate, it performed effectively and showed that in conditions of using this fertilizer with respect to the results obtained, it could decrease chemical fertilizer consumption up to 50 percents.
