Abstracts |
The purpose of this study was to evaluate the responses of lentil (Lens culinariscv. 'Ziba') to co-inoculation with arbuscular mycorrhizal (AM) fungi and some indigenous rhizobial strains varying in phosphorus (P)-solubilizing ability in a calcareous soil with high pH and low amounts of available P and nitrogen (N). A factorial experiment with completely randomized block design was conducted under controlled greenhouse conditions. The treatments consisted of (1) three inoculants of Rhizobium leguminosarum bv. viciae strains and a mixed rhizobial inoculant with an effective P-solubilizer strain of Mesorhizobium ciceri, (2) two AM fungal species, Glomus mosseae and Glomus intraradices, (3) two P sources, superphosphate and phosphate rock. Four replications were prepared for each treatment and a related control. After the growth period of three months, the dry matter of shoots plus seeds, their P and N contents, and percent of root colonized by AM fungus were measured. The results showed that the effects of AM fungi, rhizobial strains, and P fertilizers were highly significant (p < 0.01) for all the characteristics studied. The rhizobial strain with P-solubilizing ability showed a more beneficial effect on plant growth and nutrient uptake than the strain without this ability, although both strains had similar effectiveness for N-2-fixation in symbiosis with lentil. Synergistic relationships were observed between AM fungi and some rhizobial strains that related to the compatible pairing of these two microsymbionts. The P-uptake efficiency was increased when P fertilizers were applied along with AM fungi and/or P-solubilizer rhizobial strains. |
