Effects of phosphorus and nitrogen level fertility on growth parameters of Faba bean inoculated with rhizobia

Résumé

In the aim to study the influence of phosphorus and nitrogen fertilization and rhizobia inoculation on growth parameters of Faba bean, experiments were conducted in glasshouse. Isolated rhizobia from nodulated Faba bean roots were cultivated in a selective growth media. Our work suggests that nodulation may be affected by the concentration level of phosphorus and nitrogen and it is less important when the rhizosphere is deficient in phosphorus. The results indicated that phosphorus apply in combination with rhizobia inoculation increased nodules and biomass production. Highest dry weights were recorded at 125 μM and 175 μM of phosphorus and 0.5 mM and 2 mM of nitrogen. We conclude that Faba bean crop should be grown preferably with 175 μM of phosphorus and 0.5 mM of nitrogen concentration along with rhizobia inoculation under glasshouse conditions.
