It is reported for the first time the effects of Dundubia manifera insect sound at a peak frequency of 4000 Hz toward the height of rice seedlings grown through the transplanting method. In addition, the rice productivity was determined through the yield of the rice crop. The rice planted was the Situ Bagendit variety consisting of the control (without sound exposure) and treatment (with sound exposure) groups. The results showed that the exposure of insect sound affected the height of the rice seedlings and the rice productivity. This was indicated by the height of the treated rice seedlings from the 7thto the 20thdays after seeding (DAS), which was higher than the control group. The growth rates of the rice seedlings in the treatment and control groups were 2.0 cm/day and 1.6 cm/day, respectively. Furthermore, the yield of the treated rice seedlings increased by 35.42% compared to the control group. © 2022 Association of Agricultural Technology in Southeast Asia. All rights reserved.
