Algae also positively affect these microorganisms and soil fertility. The composition of potential bioproducts from algae can vary depending on the type of algae cell. The inoculation of seeds/soils with phosphate-solubilizing microorganisms is therefore a promising method to improve food production without causing environmental pollution. For this purpose, increasing doses of algae extract (0, 0.2, 0.4, 0.8, and 1%) and different phosphorus (P) sources were added to clay loam soil at the 0 and 130 mg kg−1 doses. As a result, the effect of algal extract applied in increasing doses on some growth parameters of bean plants was found to be statistically significant for both P sources. The lowest yield components were also obtained in the control treatment (-algae extract; -P). As the applied algae extract doses increased, the yield components for mono-ammonium phosphate (MAP) and dicalcium phosphate (CaHPO4) applications increased. On the other hand, the values obtained from plants treated with MAP as a source of phosphorus were higher than those obtained with CaHPO4. Increasing the level of algae extract across MAP-treated plants resulted in higher values in the plant’s upper parts but lower values in the root. Compared to other treatments, plants treated with CaHPO4 showed higher values when algaeextract was applied at concentrations of 0.8% and 1%.
