Green Music (GM), a Korean-style light music, was composed to encompass frequency range of 0~2 kH by combined use of natural sounds such as water flow, bird chirping, and animals. Crop plants were exposed to GM for two hours from six to eight o’clock in the morning during the cultivation period. Growth of plants exposed to GM increased up to 44% but the effect was variable among plant species. Sweetness of cucumber increased from 4.4 to 5.1 Brix by GM treatment. Content of rutin and GABA increased in plants exposed to GM. Foliar absorption of mineral nutrients such as N, Ca, Mg, Fe, and Zn was significantly increased in plant exposed to GM. In addition, fertility and longevity of aphids were significantly decreased in the plants exposed to ultrasonic waves, and these decreases were associated with increases of substances inhibiting feeding and pupation of pest insects. Contents of some compounds known to be involved in the disruption of feeding and pupation habits, such as rutin, GABA, and dopamine, were modulated in plants or aphids exposed to GM. With the increase of substances inhibiting pest growth and survival, the amount of insecticide applied to control pest was reduced up to 80% in farms used GM for crop production. However, the effects of sound waves were variable among plant species, seasons and farming conditions. The underlying mechanisms of the effects of sounds waves are to be understood through further studies.
