Abstract : Two field experiments were carried out to study the effects of soil inoculation with phosphorien-containing phosphate-dissolving bacteria (PDB) and/or magnesium (Mg) foliar application at the rates of 0, 0.5 and 1 mM on the growth, some chemical constituents and fruit yield and its quality of squash (Cucurbita pepo L) grown on a sandy calcareous soil. The experiment were performed in a completely randomized blocks design with six treatments, each one with four replicates. The results indicated that PDB and/or Mg significantly increased stem length, canopy dry weight plantâ€“1, number of leaves plant â€“1, stem length, canopy dry weight plantâ€“1, number of leaves plantâ€“1, leaf area leafâ€“1, leaf area plantâ€“1, leaf contents of pigments, free proline, nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), and calcium (Ca) and the ratio of Ca/Na, while leaf Na content was reduced. The application of PDB and/or Mg also increased fruit yield and its components (i.e., number of fruits plantâ€“1, fruit weight plantâ€“1 and fruit yield fedâ€“1). It has been concluded that the applications of Mg and PDB have pronounced a positive reflection on the growth, fruit yield and its components of squash plants grown on sandy calcareous soil. PDB and Mg, therefore, have the potential to be used as a soil inoculation and foliar application, respectively for squash and may for various crops to overcome the adverse effects of the newly-reclaimed sandy calcareous soils.
