Increased soluble salts in soil and irrigation water threaten the sustainability of crops. This causes food insecurity directly by reducing staple crop yield indirectly limiting fodder forage production. Recently, plant-growth-promoting rhizosphere microorganism utilization improved productivity under stress. Therefore, this research was conducted to find Sorghum bicolor growth improvement potential exogenous application five different Pseudomonas strains salinity a pot experiment.

Partial Nitritation/Anammox (PN/A) can achieve green, economical, and efficient biological nitrogen removal; however, the PN process contributes significantly to nitrous oxide (N2O, third most important greenhouse gas) emissions. Balancing stability of systems while reducing N2O emissions, particularly under varying salinity conditions, is a key challenge in applying PN/A for high-salinity high-ammonia wastewater treatment. This study explored long-term effects on performance emissions treating wastewater. The results showed that specific ammonia oxidation rates control two salinity-acclimated reactors were 78.84, 75.03, 42.60 mg N/(g VSS·h), indicating low (2.5 g NaCl/L) had minimal effect, high (10 inhibited ammonia-oxidating bacteria associated nitritation processes. Moreover, emission factors increased from 0.08 ± 0.04% 0.24 0.03% as rose 0 10 NaCl/L. Further analysis revealed stimulated production both aerobic anoxic stages. Particularly, by 2.84-11.14 times aerated stage 0.61-2.04 nonaerated (i.e. settling stages). Isotopic pathway indicated enhanced primarily stimulating nitrite reduction pathway. Additionally, mechanism investigation examined combined salinity-induced changes sludge properties microbial community These findings provide valuable insights treat high-strength understanding mechanisms

Harnessing silicon nanoparticles and various forms of silicon for enhanced plant growth performance under salinity stress: application and mechanism

Discover Nano, Год журнала: 2025, Номер 20(1)

Опубликована: Май 29, 2025

Agricultural production faces significant losses due to salinity, drought, pests, insects, and weeds, particularly in nutrient- fertilizer-deficient soils. This review focuses on enhancing the productivity of crops grown dry saline environments. Silicon nanoparticles (Si NPs) silicon compounds (SiO₂/SiO₃2⁻) have shown potential improve crop yields while mitigating effects biotic abiotic stresses. As an eco-friendly alternative chemical fertilizers, herbicides, pesticides, Si NPs stimulate germination, plant growth, biomass accumulation, nutrient absorption their small size, large surface area, ease cellular penetration. These reduce salinity stress by modulating gene expression, leading activation antioxidant enzymes such as SOD, CAT, APX, which help combat reactive oxygen species (ROS). Treatment with low concentrations nano-silica (100-300 mg/L) significantly enhances plants' tolerance salinity. NPs, when combined soluble polymeric materials rhizobacteria, provide a sustainable impact slow-release properties, offering prolonged protection against bacterial viral infections under conditions.
