Soil acidity is a divesting factor that restricts crop growth and productivity. Conversely, silicon nanomaterials (Si-NMs) have been praised as blessing of modern agricultural intensification by overcoming the ecological barrier. Here, we performed sequential study from seed germination to yield performance mustard (Brassica campestris) crops under acid-stressed conditions. The results showed Si-NMs significantly improved seedling acid stress situations. These might be associated with increased antioxidant activity preserve ratio GSH/GSSG AsA/DHA, which restricted soil acidity. Moreover, in field regimes diminished acid-stress-induced inhibitions, evidenced net photosynthesis biomass accumulations. Again, triggered all critical metrics productivity, including oil content. Additionally, Si-NMs, upon dolomite supplementation, further yields related farming resilience. Therefore, present highlighted crucial roles sustainable expansion cropping intensification, especially areas affected

Drought stress significantly limits crop productivity and poses a critical threat to global food security. Silica nanoparticles (SiO2NPs) have shown potential mitigate drought stress, but the role of nanostructure on overall efficacy remains unclear. This study evaluated solid (SSiO2NPs), porous (PSiO2NPs), hollow (HSiO2NPs) SiO2NPs for their effects drought-stressed tomatoes (Solanum lycopersicum L.). Silicic acid release rates followed order: HSiO2NPs > PSiO2NPs SSiO2NPs Bulk-SiO2. Compared untreated controls, foliar application under improved shoot Si concentrations plants' dry weight. These treatments also enhanced antioxidant enzyme activities (catalase, peroxidase, superoxide dismutase) phytohormone-targeted metabolome levels (jasmonic acid, salicylic auxin), contributing greater tolerance. Conversely, SSiO2NPs, silicic Bulk-SiO2 had minimal impact plant weight or physiological responses. results highlight importance architecture in alleviating promoting sustainable agriculture.
