Reducing drought stress in rice (Oryza sativa L.) through silicon-induced improvements in photosynthetic pigments, leaf gas exchange, biomass, and antioxidant activities.

Abstract excerpt

Drought impacts sustainable crop production by disrupting the fundamental metabolic processes of plants leading to reduced photosynthesis, leaf gas exchange, and oxidative damage. Silicon can mitigate the negative consequences of water stress. In a field experiment in 2020 and 2021, we applied silicon foliar spray to rice (Oryza sativa L.) genotypes at different growth stages (tillering, panicle initiation, 50%...
