Abstract The global agricultural sector is under tremendous pressure due to population growth and the consequent demand for food. Drought stress a hazardous threat crops around globe. Spinach (Spinacia oleracea L.) cultivated worldwide. leafy vegetable vulnerable drought having higher water content. altered its biochemical composition stunted growth. present study was designed highlight ameliorative role of iron nanoparticles (Fe-NPs) against stress. A pot experiment performed in which three irrigation levels with 100, 50 25% field capacity were used. Fe-NPs synthesized by green synthesis method using rice straw. analyzed various techniques including UV, SEM, FTIR, XRD EDX. Foliar application (40 mg/L) employed. Along this foliar spray salt (FeSO4; 40 also applied comparative analysis. Stressed-spinach plants showed reduction parameters, whereas readily stimulated stressed plants. Growth parameters (fresh dry weight root shoot, number leaves leaf area), relative content, total proteins, photosynthesis related attributes (ΦPSII, chlorophyll florescence, b carotenoids) nutrients uptake decreased because Furthermore, shows significant increase proline, hydrogen peroxide, malondialdehyde enzymatic antioxidants. Application increased photosynthesis, antioxidant enzyme activity mineral nutrient intake, turn improved membrane function. Moreover, it excess ROS generation brought on nutritional status secondary metabolites (proline & phenolics) enhanced Fe-NPs. These findings suggest that could be helpful tool lessening harmful consequences boosted defense mechanisms mitigate negative

The present study was designed to highlight the ameliorative role of iron nanoparticles (FeNPs) against drought stress in spinach (Spinacia oleracea L.) plants. A pot experiment performed two-way completely randomize design with three replicates. For levels were used by maintaining field capacity soil. This included control (100% capacity), moderate (D1; 50% capacity) and severe (D2; 25% capacity). FeNPs synthesized green method using rice straw applied along precursor FeCl3, as Fe source for synthesis FeNPs, through foliar spray (40 mg L− 1 both). Growth parameters, efficiency photosynthetic machinery, gas exchange attributes, total soluble proteins, inorganic ions (Ca2+, K+ & Fe2+) significantly reduced at both D1 D2 levels, compared supplements form FeCl3 improved these attributes conditions. Malondialdehyde, H2O2, relative membrane permeability (stress indicators) activities antioxidants increased response stress. further antioxidant defense efficiently lowered effects indicators. These resulted growth S. plants Results showed that had more prominent on FeCl3. findings suggest could be a helpful tool lessening harmful consequences this can abiotic alleviation other crops well.

Increasing the productivity of crops in water deficit circumstances is great significance order to face challenge securing global food production. Nowadays, use biochar (BC) and arbuscular mycorrhizal fungi (AMF) are considered as one most effective methods for empowering plants deal with drought stress. However, literature regarding effects simultaneous AMF+BC on under stress scarce. Hence, present study was conducted consider combined application AMF physiological biochemical properties lavender various levels irrigation. The first factor includes three irrigation regimes 90% field capacity (FC), 60% FC, 30% respectively, corresponding normal irrigation, mild severe second included a fertilizer or microbial inoculant source, which were respectively: no inoculation (control), AMF, BC, co-application along BC. highest nutrient, chlorophyll carotenoid content, fresh, dry weight recorded conditions AMF+BC. significantly increasing activity antioxidant enzymes against oxidative damage caused by reducing accumulation proline malondialdehyde.
