Abstract:
During the kharif season of 2020 and 2021, a field trial was conducted at the Dr. Norman E. Borlogue Crop Research Centre, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar (Uttrakhand), India. In this study, we found that Si application rose dramatically in eight rice genotypes that were given various treatments, including control (T1), Si (0.6% Ortho silicic acid) (T2), Si (0.6% Ortho silicic acid) + water stress (T3), and water stress only (T4). The finding of the study shows that the fertilization of silicon (0.6%) increased plant growth, MSI and RWC content in rice as compared to control. Silicon (0.6%) supplemented plants (T2) showed a maximum increment in growth rate of US-312 (22.33%) and IRRH-314 (20.98%) at tillering, IIRRH-148 (14.42%) and US-314 (14.91%) at panicle initiation for plant height, and US-312 (32.18% and 28.85%) for MSI and DRR Dhan (8.43% and 8.33%) for RWC as compared to control (T1) in 2020 and 2021. The goal of this study was to observed beneficial effects of silicon on growth rates and physiological responses in different rice genotypes.
