Field experiment was conducted in Mohajaran region, Abu-Al-Khaseeb district, Basrah province during the growing season 2018. The study was aimed to evaluate the effect of integration of chemical fertilizer (triple superphosphate) with manure (cattle residue) and/ or biofertilizer (Aspergillus niger) on some soil properties and phosphorus availability to sunflower during growing season. Samples were collected at seedling, vegetative growth, flowering and post-harvest stage. pH, EC, moisture content and available P were determined. Results showed that application of chemical fertilizer significantly affected soil pH, EC, and available P, but showed no effect on soil moisture content. Soil pH decreased and EC increased at seedling stage, while EC was decreased at harvest. Available P values were increased at all growing stages. Incorporation of manure at rate of 30 Mg ha considerably decreased the soil pH and increased EC at seedling stage, soil moisture, and available P at all growing stages.. Inoculation the seeds with A. niger showed no significant effect on soil pH, EC, and soil moisture but significantly increased available P, at vegetative growth and flowing stages . Results showed that the effect of biofertilizer on available P was in bar with the application of manure at rate of 15 Mg ha .Highest value of available P was associated with combination of 120 Kg P ha + 30 Mg ha + inoculation with fungus.
