Article Abstract
This study investigated the effects of four selenium fertilizers (nano-Se, EDTA-chelated Se, organic Se, and microbial Se) at three concentrations (50, 25, and 12.5 mg·L) on garlic ( L. cv. 'Xusuan 918') through foliar application during critical growth stages. Comprehensive evaluation combining agronomic traits, yield components, nutritional quality (soluble sugars, vitamin C), and selenium accumulation revealed distinct fertilizer-specific responses. Organic Se at 50 mg·L (O1) maximized vegetative growth (21.83% increased plant spread), while 25 mg·L microbial Se (M2) showed optimal yield enhancement (10.04% higher bulb dry weight vs. CK). Notably, 50 mg·L nano-Se (N1) achieved simultaneous improvement in nutritional quality and selenium biofortification (29-fold bulb Se enrichment). Principal component analysis integrated with membership function method identified N1 treatment (D-value = 0.571) as the most effective protocol for selenium-enriched garlic production, demonstrating the importance of fertilizer selection for crop-specific selenium management strategies.

Background: Fertilization of plants with selenium (Se) can enhance their resistance to abiotic stresses and improve human health and nutrition. However, Se fertilization in olive trees remains underexplored. This study evaluated the effect of foliar sodium selenite fertilization on leaf Se content, oxidative stress, olive tree productivity, biofortification of extra virgin olive oils (EVOO), and their physicochemical and antioxidant attributes in two mature 'Arbequina' olive orchards.

Background: Selenium-coated chitosan nanoparticles (CTS-Se NPs) have been proposed as innovative engineered nanoparticles with the potential to alleviate various abiotic stresses, thereby enhancing plant growth and productivity. However, evidence of their efficacy remains limited. In this study, the effects of CTS-Se NPs (10 and 20 mg L⁻¹), along with CTS NPs (0.

Microbial synthesis of selenium nanoparticles (SeNPs) as a fertilizer can promote the development of selenium-rich agricultural products. However, most known selenium-reduction strains exhibit a tolerance to selenite of ≤ 100 mmol/L and possess relatively low reduction efficiency. In this study, three strains capable of tolerating selenite concentrations of > 300 mmol/L were screened from selenium-rich soil in Bama, Guangxi, China.
