Objectives:
This study was conducted to investigate the effects of mycorrhizal fungi and plant growth-promoting bacteria biofertilizers on the yield and physiology of wheat under different irrigation regimes. Another objective was to examine the physiological and qualitative indices of wheat under water stress.
Materials and methods:
This research was carried out during the 2021-2022 growing season as a factorial experiment in a randomized complete block design with three replications at the Ardabil Research Center. The factors included four levels of fertilizer (control, mycorrhiza, plant growth-promoting bacteria, and combined application of both) and three levels of irrigation regimes (full irrigation, 50% water requirement, and no irrigation). Wheat seeds were inoculated with microbial and fungal inoculants using the seed coating method.
Findings:
The interaction between biofertilizers and irrigation regimes was significant for all traits. The highest grain yield (4891.6 kg/ha), biological yield (10952.8 kg/ha), and 1000-grain weight (43.5 g) were achieved in the combined treatment under full irrigation. Qualitatively, the highest grain protein percentage (11.7%), Zeleny number (50.24), and gluten index (45.72) were also observed in this treatment. Physiologically, the highest leaf chlorophyll content (52.96) was recorded in the combined treatment, while the highest proline content (6.98 μmol/g) was observed in the control treatment under no irrigation.
Conclusion:
combined application of mycorrhizal fungi and growth-promoting bacteria biofertilizers was identified as the effective approach for improving the yield, quality, and physiological resistance of wheat. The use of biofertilizers can be recommended as a sustainable strategy for enhancing wheat production under different irrigation conditions.
