This study on the physical factors affecting the growth of lotus in the lotus pond of Suksan Village , Khok Lo Subdistrict, Mueang District, Trang Province, aims to investigate the physical factors that influence lotus growth. A study of the quality of water at a temple in Kok Loh Subdistrict, Mueang District, Trang Province , found that: The average temperature in the pool is 28.37 ° C. The optimal temperature for lotus growth is between 15-35 ° C , while the average soil temperature is 30 ° C. The optimal temperature for lotus growth is between 21-32 ° C. The average pH of the water is 7.0 ( neutral ) , which is within the ideal range. The ideal pH should be between 5.5 and 8.0 , allowing the lotus to absorb nutrients from the soil and water effectively for growth. The soil nutrient content ( NPK ) was found to be... Nitrogen levels were in the range of 7.33 mg/kg, and phosphorus levels were in the range of 8.66 mg/kg . Potassium levels were in the range of 23.66 mg/kg. The transparency value was 0.7 m , which is low but still within the standard range; it should be 0.3-0.6 m. This indicates a relatively high amount of suspended solids in the water. This high amount of suspended solids results in less light being able to penetrate into the water layer. This affects the photosynthesis process of underwater plants or other organisms that require light. The average humidity in the air is 46.2%, which is considered relatively low compared to the criteria for optimal lotus growth, which should be above 60%. The dissolved oxygen level of 2.5 ml/g indicates a certain level of oxygen, but this is below the standard range of 5-8 ml/g , which negatively impacts the ecosystem and physical water quality. In conclusion, physical factors definitely affect the growth of lotus, which is beneficial for the growth of this aquatic plant.
