Research from Ilam, Iran, sheds light on the devastating effects of climate change on agricultural productivity and food security. The study investigates the impact of zinc oxide nanoparticles (ZnO NPs) and mycorrhizal fungi on soybean yield and oil quality under drought stress conditions.

Key Takeaways:

  • The study reveals that drought stress reduced soybean colonization by 10% under moderate to severe water deficit conditions.
  • The combined application of ZnO NPs and arbuscular mycorrhizal fungi (AMF) enhanced colonization by 10% relative to AMF alone.
  • The combined treatment of ZnO NPs+AMF significantly increased nitrogen, phosphorus, potassium, and zinc uptake by 82.61%, 100.49%, 94.78%, and 143.11%, respectively, under optimal irrigation conditions.
  • The combined treatment increased proline and soluble carbohydrates under severe drought conditions by 77.29% and 58.75%, respectively, compared to the control.
  • The activity of antioxidant enzymes such as ascorbate peroxidase, guaiacol peroxidase, and catalase increased by 85.92%, 111.18%, and 80.13%, respectively, reducing oxidative stress markers such as malondialdehyde (51.27%) and hydrogen peroxide (63.44%) compared to untreated conditions.
  • In terms of both oil quantity and quality, the combined treatment of ZnO NPs+AMF under optimal irrigation conditions increased linoleic and linolenic acid concentrations by 60.75% and 43.91%, respectively, while decreasing palmitic and stearic acid concentrations by 50.45% and 24.88%, respectively.
  • The combined application of ZnO NPs+AMF resulted in a 145.47% increase in seed yield and a 24.32% increase in oil content compared to moderate to severe drought stress conditions without treatment.
  • The study concludes that the combined use of ZnO NPs and AMF can serve as an effective strategy to improve crop performance and oil quality under drought stress conditions.

Statistics:

  • 10% reduction in soybean colonization under moderate to severe water deficit conditions.
  • 82.61% increase in nitrogen uptake, 100.49% increase in phosphorus uptake, 94.78% increase in potassium uptake, and 143.11% increase in zinc uptake under optimal irrigation conditions.
  • 77.29% increase in proline, 58.75% increase in soluble carbohydrates, 85.92% increase in ascorbate peroxidase activity, 111.18% increase in guaiacol peroxidase activity, and 80.13% increase in catalase activity under severe drought conditions.
  • 60.75% increase in linoleic acid concentration, 43.91% increase in linolenic acid concentration, 50.45% decrease in palmitic acid concentration, and 24.88% decrease in stearic acid concentration under optimal irrigation conditions.
  • 145.47% increase in seed yield, 24.32% increase in oil content, and 9.7% increase in iodine value under optimal irrigation conditions.
