Background
- Soil salinity, worsened by climate change, severely impacts crop productivity.
- Approximately 20% of irrigated lands face challenges due to soil salinity.
- Sustainable agriculture requires innovative solutions for salt-affected regions.
Purpose Of The Study
- To evaluate zinc (Zn) and silicon (Si) nanofertilizers for maize (<i>Zea mays</i> L.) under saline and non-saline conditions.
- To assess the impact of nanofertilizers on maize growth, nutrient uptake, and yield.
- To explore nanotechnology as a strategy for mitigating salinity stress in crops.
Main Methods
- Synthesis and characterization of ZnO and SiO<sub>2</sub> nanoparticles (NPs).
- Split-plot field experiment applying nano and conventional Zn/Si fertilizers.
- Evaluation of agronomic, chemical, and physiological parameters, including yield and nutrient uptake.
Main Results
- Nano Zn/Si application significantly enhanced maize cob length and grain yield.
- Nano Si application increased biomass by 110% and nutrient use efficiency by over 100%.

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.
Plant cell cytoplasm has a high solute concentration, which causes water to flow from the soil into the plant due to osmosis. However, excess salt in the surrounding soil increases the soil solute concentration, reducing the plant’s ability to take up...
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
