“…The contents of (Fe, Mn, Cu, B, and Zn) micronutrients were the most significantly increased upon the treatment of CNT with values of 11.731 µg/g, 3.023 µg/g, 0.142 µg/g, 0343 µg/g, and 0.279 µg/g respectively. These results were agreed with Lyu et al ( 2017), Dağhan, (2018), Gülmezoğlu et al, (2020), andŠebesta et al, (2021), while the treatments of BNT showed that the micronutrient contents of (Fe, Mn, Cu, B, and Zn) were significantly increased with values of 5.042 µg/g, 1.251 µg/g, 0.043 µg/g, 0.143 µg/g, and 0.095 µg/g respectively.…”

“…It seems that the integrative application of TiO 2 + AMF improves the nutrient accessibility as a result of stronger seedlings and higher metabolic efficiency (e.g., nutrient transport), which have an important role in the production of carbohydrates and the development of the glandular trichomes, EO channels, and secretory ducts. Additionally, TiO 2 nanoparticles help to convert inorganic N into organic N in the form of protein and chlorophyll, which leads to an increase in the photosynthetic rate [40]. Zhao et al [41] noted that the increase in primary photosynthesis compounds including erythrose-4-phosphate, phosphoenolpyruvate, pyruvate, and glyceraldehyde-3-phosphate plays a main role in increasing terpene constituents and EO productivity in medicinal and aromatic plants.…”

Drought stress is known as a major yield-limiting factor in crop production that threatens food security worldwide. Arbuscular mycorrhizal fungi (AMF) and titanium dioxide (TiO2) have shown to alleviate the effects of drought stress on plants, but information regarding their co-addition to minimize the effects of drought stress on plants is scant. Here, a two-year field experiment was conducted in 2019 and 2020 to evaluate the influence of different irrigation regimes and fertilizer sources on the EO quantity and quality of sage (Salvia officinalis L.). The experiment was laid out as a split plot arranged in a randomized complete block design with three replicates. The irrigation treatments were 25, 50, and 75% maximum allowable depletion (MAD) percentage of the soil available water as non-stress (MAD25), moderate (MAD50), and severe (MAD75) water stress, respectively. Subplots were four fertilizer sources including no-fertilizer control, TiO2 nanoparticles (100 mg L−1), AMF inoculation, and co-addition of TiO2 and AMF (TiO2 + AMF). Moderate and severe drought stress decreased sage dry matter yield (DMY) by 30 and 65%, respectively. In contrast, application of TiO2 + AMF increased DMY and water use efficiency (WUE) by 35 and 35%, respectively, compared to the unfertilized treatment. The highest EO content (1.483%), yield (2.52 g m−2), and cis-thujone (35.84%, main EO constituent of sage) was obtained in MAD50 fertilized with TiO2 + AMF. In addition, the net income index increased by 44, 47, and 76% with application of TiO2 nanoparticles, AMF, and co-addition of TiO2 +AMF, respectively. Overall, the integrative application of the biofertilizer and nanoparticles (TiO2 + AMF) can be recommended as a sustainable strategy for increasing net income and improving EO productivity and quality of sage plants in drought stress conditions. Future policy discussions should focus on incentivizing growers for replacing synthetic fertilizers with proven nano and biofertilizers to reduce environmental footprints and enhance the sustainability of sage production, especially in drought conditions.

“…Similarly, Begum et al [ 36 ] observed that the concentration of nitrogen, phosphorus, and potassium of tobacco ( Nicotiana tabacum L.) increased by 48.8, 89.1, and 111.2%, respectively, with AMF inoculation. Additionally, it has been reported that the usage of TiO 2 NPs enhanced the content of N in plants by increasing enzyme activities involved in N metabolisms and also improving transformation of inorganic N to organic N [ 37 , 38 ].…”

Drought stress (DS) negatively affects plant growth, productivity, and quality in semi-arid and arid regions. Nowadays, application of biofertilizers and stress-modulating nanoparticles (NPs) improves plant performance under stressful conditions. The study evaluated the impacts of arbuscular mycorrhizal fungi (Myco-Root) and TiO2 NPs on the nutrient uptake, dry yield, essential oil (EO) productivity, and EO quality of peppermint (Mentha piperita L.) under different irrigation regimes. The treatments included three irrigation regimes containing irrigation after 20% (I20, well-watered), 40% (I40, mild DS), and 60% (I60, severe DS) maximum allowable depletion (MAD) percentage of the soil’s available water as well as four fertilizer sources contain no fertilization (control), Myco-Root biofertilizer, TiO2 NPs, and an integrative application of Myco-Root + TiO2 NPs. The results demonstrated that the highest (195.72 g m−2) and the lowest dry yield (78.76 g m−2) of peppermint was obtained in well-watered conditions with integrative application of Myco-Root + TiO2 NPs and severe drought stress (I60) without fertilization, respectively. The dry yield of peppermint was reduced by 27.7 and 53.4% in mild (I40) and severe drought stress (I60), respectively. The maximum EO content (1.49%) and EO yield (2.30 g m−2) was recorded in mild drought stress (I40) treated with Myco-Root + TiO2 NPs. Based on the GC-MS and GC-FID analysis, 29 constituents were identified in peppermint EO, with the major constituents being menthol (38.99–52%), menthone (12.72–20.13%), 1,8-cineole (6.55–7.84%), and neo-menthol (3.14–4.52%), respectively. The maximum content of menthol, 1,8-cineole, and neo-menthol was obtained under mild drought stress (I40) fertilized with Myco-Root + TiO2 NPs. The results indicate that the integrative application of Myco-Root + TiO2 NPs could be used as an alternative method of using chemical fertilizers in sustainable agricultural systems for improving the EO quantity and quality of peppermint grown under drought stress conditions.
