Evaluating the Effectiveness of Biogenic Silicon Sources and Na-Silicate as Silicon Fertilizers in Mitigating Boron Toxicity in Maize
Abstract
Abstract Excess boron (B) in soil can severely damage plant tissues, reducing growth and yield. This study evaluated the effectiveness of biogenic silicon (Si) sources; rice husk (RH), modified rice husk (MRH), and RH-derived Nano-Si compared with a conventional Si source, Na-silicate, in mitigating B toxicity in maize. Maize plants were grown in soil containing 30 mg kg -1 B under screenhouse conditions. MRH and Nano-Si were characterized using Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). All Si sources were applied at 200 mg Si kg -1 soil. Structural analyses indicated that MRH consisted of particles >100 nm, whereas Nano-Si had spherical particles
