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 plant–1, number of leaves plant –1, stem length, canopy dry weight plant–1, number of leaves plant–1, leaf area leaf–1, leaf area plant–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 plant–1, fruit weight plant–1 and fruit yield fed–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.
