Rocking Radishes: The Effect of 8 kHz Sound on Biomass Accumulation in Raphanus sativus

Overview

Can sound waves affect how plants grow? I tested whether a high-pitched sound (8 kHz) at different loudness levels (0 (no sound), 55, 65, and 75 decibels) changes how radish plants grow. I grew 40 radish plants for 26 days under identical conditions, except for the sound they were exposed to each day. I compared their growth by measuring their dry mass at the end. There was no significant difference between the plants that were exposed to sound and those that weren't. This suggests that high-frequency sound at these levels does not affect radish growth positively or negatively. This is important because it helps scientists and farmers figure out which sound conditions are useful or harmful and which are not, for improving crop growth. Beneficial sound conditions could reduce reliance on fertilizers and pesticides, therefore being a more sustainable way to improve plant growth.
