Abstract
Two field experiments were conducted at the Experimental Farm of Faculty of agriculture Damanhour Branch, Alexandria University at El-Bostan region to evaluate the effects of phosphorous solubilizing bacteria( PDB) (Bacillus megaterium as a commercial product Phosphorein), and Vesicular Arbuscular Mycorrhiza (Glomus macrocarpium) with four different fertilization levels of inorganic phosphorus (0, 30, 60 and 90 kg P2O5 fed.-1) on the growth, seed yield, seed protein, N, P and K contents of seeds of common bean (Phaseolus vulgaris L.) cv."Bronco". The results revealed that Inoculation of common bean seeds with Mycorrhiza gave significantly higher mean values of dry seed yield fed.-1 than those inoculated with Phosphorein in both seasons also the inoculation of common bean seeds with Mycorrhiza or Phosphorein and application of 60 or 90 kg P2O5 fed-1. was the best combined treatment Moreover, inoculation with VAM or PDB under the applied P-mineral levels supply reflected significant difference on the percentage of N, P and protein content in dry seeds in both seasons. Polynomial quadratic models were established and used to describe seed yield responses of bean plants inoculated with Phosphorein or Mycorrhiza in combination with four different levels of P-mineral. The equation constants were used to calculate maximum rates of P fertilizer (Pmax) and the corresponding maximum yields (Ymax.) for all treatments.
