| Abstract | 4 Abstract: Despite abundant amounts of phosphorus in parent material, the soil phosphors availability is limited for plant. Some soil micro-organisms enhance solubility of phosphate in calcareous soils. This study investigated the effects of phosphate solubilizing bacteria (PSB) and arbuscular mycorrhizal fungi (AMF) and their interactions on crop performance, changes in biological population and inorganic phosphorus fractions. The experimental design was split plot factorial with on a complete randomized block design. The treatments included four soil types (clay, clay loam, loam and sandy loam), three phosphorus fertilizer levels (0, 20 and 40 mg kg ) and four levels of phosphate solubilizing microorganisms (PSM). At time 1 physiological maturity, dry matter weight (shoots or roots), plant height, spike length, grain spike number and grain yield in each spike were measured. The percentage of colonized roots, number of PSB and fungi spore and inorganic phosphorus fractions in the root zone were determined. Resulted indicated that the highest shoot dry matter was in clay loam soil (21.5 g pot ). Combined application of PSB and AMF increased shoot dry matter 1 yield, seed grain spike number and grain yield by 52, 19 and 26%, respectively compared to the controls. Phosphorus application increased Olsen-P, Ca -P and Ca -P% while biological fertilizers reduced the 28 amount of Ca -P and ca -P%. 28 |
