A filed experiment in split-split plot design was conducted on a calcareous soil at Nubaria Agriculture Research Station, El-Behera Governorate, Egypt, during the growing seasons of 2012/2013 and 2013/2014 to study the effectiveness of seed inoculation by Bacillus megaterium (as a phosphate dissolving bacteria (PDB)) on enhancement the P availability and improvement use efficiency of many inorganic phosphorus forms and rates in soil to improve the production of faba bean (Vicia faba L.) cultivar sakha 4 . Three fertilizer P forms namely P1; single super phosphate 15.5% P2O5 (SSP), P2; triple super phosphate 46% P2O5(TSP) and P3; phosphoric acid (H3PO4) 72.4% P2O5 (PA), at 75% and 100% of recommended doses (45 kg P2O5 fed-1 RD). The results revealed that PDB inoculation increased their population in soil and significantly increased the availability of P in calcareous soil whether applied alone or combined with added P forms compared without it, where the treatments of TSP at 75 and 100% RD combined with PDB gave the highest percentage (125.8, 136.4%) at the 50 days age and the lowest percentage (50.9, 53.3%) at harvest, respectively. The results indicated to increase macronutrients uptake by faba bean plants, which positively reflected on quantities and qualities of yields. It can be concluded that adding TSP at 75% RD combined with PDB inoculation is the recommended for improving the productivity of faba bean crop, while the means values of seed yield relatively increased about with 41.4% over the same treatment without PDB and about 34.2, 36.9% for PDB inoculation and TSP forms as individual effect respectively. It was noticed that the PDB-inoculated seeds increased phosphorus use efficiency (PUE), phosphorus agronomic efficiency (PAE) and phosphorus recovery efficiency (PRE) by about 33.04, 101.1 and 138.1%, respectively over the uninoculated. Triple superphosphate (TSP) has the greater efficiency whether it was alone or combined with PDB inoculation at 75% RD addition compared to other forms.
