The study looked at how different amounts of silicon affect the growth and photosynthesis of japonica rice plants. They tested silicon levels of 0, 30, 80, 130, and 180 mg/L on rice seedlings. Results showed that the best plant height was at 80 mg/L of silicon, while the shortest roots were at 30 mg/L. The highest chlorophyll levels were seen at 30 mg/L, and the best balance of chlorophyll types was at 80 mg/L. Overall, the right amount of silicon can make rice plants stronger, help them photosynthesize better, and increase their yield.
