Title

Rhizobia as complex biofertilizers for wheat: Biological nitrogen fixation and plant growth promotion

Yuliya Serazetdinova; Ekaterina Borodina; Natalya Fotina; et al. Foods and raw materials 2025. doi:10.21603/2308-4057-2026-1-669

Other claims from this paper (12)

Observation All tested rhizobial strains produced phytohormones, fixed nitrogen and solubilized phosphates.
Observation All tested rhizobial strains solubilized zinc and synthesized ACC deaminase.
Observation The strains antagonized F. graminearum.
Observation The strains antagonized Xanthomonas campestris.
Intervention effect E. meliloti 441 B-219 treatment increased wheat shoot and root length.
Intervention effect R. tropici B-216 treatment increased wheat shoot and root length.
Intervention effect E. meliloti 441 B-219 treatment increased chlorophyll and carotenoid contents in some wheat varieties.
Intervention effect R. tropici B-216 treatment increased chlorophyll and carotenoid contents in some wheat varieties.
Intervention effect R. tropici positively affected shoot and root weight in all wheat varieties.
Intervention effect E. mexicanus B-4064 positively affected only germination in some wheat varieties.
