Screening for phosphate solubilising rhizobia from faba bean in Marrakech region field cultures
Résumé
Rhizobia and phosphorus (P)-solubilising bacteria are important to plant nutrition. These microbes also play a significant role as plant growth-promoting rhizobacteria (PGPR) in the biofertilization of crops. The present study was conducted in order to select rhizobial strains adapted to low P, isolated from faba bean nodules in Morocco and to investigate their ability to solubilise the mineral P. Our results revealed that among 100 isolates, 15 are able to solubilising the mineral P using TCP test. 40 strains were evaluated for their effect on the growth of faba plant and were genotypically characterized. Preliminary results show contrasting effect of strains on nodulation rate and plant growth.
