Biofertilizer and biostimulant potentials of phosphate-solubilizing Bacillus subtilis subsp. subtilis M1 strain and silicon in improving low phosphorus availability tolerance in rosemary.

The present study aimed to evaluate the single and combined effects of Si exogenous treatment and Bacillus subtilis subsp. subtilis M1 strain inoculation on rosemary tolerance to low phosphorus (P) availability. Hence, rosemary plants were fertilized with 250 µmol Ca3HPO4 (stressed plants) or 250 µmol KH2PO4 (control plants) under Si treatment and B.

Synergistic effect of PF9 and Rm41 on Moroccan alfalfa population grown under limited phosphorus availability.

This study looked at the synergistic effect of PF9 and Rm41 on the Moroccan alfalfa population () grown under symbiotic nitrogen fixation and limited phosphorus (P) availability. The experiment was conducted in a growth chamber and after two weeks of sowing, the young seedlings were inoculated with Si Rm41 alone or combined with a suspension of PF9. Then, the seedlings were submitted to limited available P (insoluble P using CaHPO) a soluble P form (KHPO) at a final concentration of 250 μmol P·plant·week.
