Abstract

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.
