Combined supplementation of selenium and silica boosts growth and yield of rice (<i>Oryza sativa</i> L.) by stimulating photosynthetic efficiency and nutrient uptake.

ABSTRACT: Rice, a staple food for more than half of the global population, is often exposed to arsenic (As) which disrupt the photosynthetic efficiency and reduce growth and yield. However, selenium (Se) and silica (Si) supplementation counteract it. In this study, simulated pot experiments were conducted to evaluate the effects of different species and doses of Se [i.e. selenite (Se^IV) and selenate (Se^VI); 0.5 and 1 mg l^-1] and Si (0.4%), on growth, yield, photosynthesis and nutrient elements composition of rice under As (1 mg l^-1) exposure. Correlation analysis revealed that As significantly reduced uptake of nutrient elements from soil, which subsequently reduced their accumulation in leaves, specially those are involved in chlorophyll synthesis i.e. ma
