Silicon Nano-Fertilizer-Enhanced Soybean Resilience and Yield Under Drought Stress.

ABSTRACT: Drought stress threatens agriculture and food security, significantly impacting soybean yield and physiology. Despite the documented role of nanosilica (n-SiO₂) in enhancing crop resilience, its full growth-cycle effects on soybeans under drought stress remain elusive. This study aimed to evaluate the efficacy of n-SiO₂ at a concentration of 100 mg kg^-1 in a soil medium for enhancing drought tolerance in soybeans through a full life-cycle assessment in a greenhouse setup. To elucidate the mechanisms of n-SiO₂ action, key physiological, biochemical, and yield parameters were systematically measured. The results demonstrated that n-SiO₂ significantly increased silicon content in shoots and roots, restored osmotic balance by reducing the
