Objectives: The objective of this study was to determine how different sound frequency values effect on plant growth, development and nutrient element uptake of Sansevieria trifasciata. Methods/Statistical analysis: In the study, Sansevieria trifasciata plants were exposed to 3 different frequency values as 600 HZ sound wave in the first week, 1240 HZ in the second week and 1600 Hz sound waves in the third week at 90 dB adjusted as constantly. At the end of applications practiced each week, nutritional element and chlorophyll analysis were performed in leaf samples. Findings: The content of nitrogen, potassium, and phosphor increased in the plants at 90 dB that was kept as constant during the research process and 600 HZ that is the first frequency value when they underwent a stress. When the frequency level was increased to 1240 HZ, whereas phosphor and potassium uptakes decreased significantly than the control plants, the level of nitrogen was determined as nearly the same with the control plants. In terms of calcium, magnesium, and zinc element contents, zinc and magnesium at 600 HZ value was at a lower value than the control plants and calcium had a closer value to the control plants. Finally, there was no change at chlorophyll content in plants kept at the lowest frequency. However, as the frequency increased, in other words as the stress increased, the increase at the amount of the chlorophyll also appeared significantly. Application/Improvements: The results indicated that N, P and K uptake increased at 1600 Hz; and Mg, Ca and Zn uptake increased at 1240 HZ. Fe uptake was negatively affected at all frequency levels. The chlorophyll content found no significant at any frequency value.
