Applied studies of the plant meridian system: II. Agri-wave technology increases the yield and quality of spinach and lettuce and enhances the disease resistant properties of spinach.

Agri-wave technology is composed of both a special frequency sound wave and a microelement fertilizer. In both components, the effect of sound waves on plants is more than that of fertilizers, but the best function is a combination of the two. Treatment by Agri-wave technology stimulated the growth rate and increased the yield of spinach. In small plot tests, the length and width of the treated spinach leaf was 50.8 cm and 20.3 cm, respectively, whereas the untreated leaves were 29.20 cm and 8.9 cm. The fresh weight of treated spinach was 0.42 kg. This was 5.5 times higher than that of the untreated spinach. In large area testing (17 hectares), the results of two tests show that the yields of the treated spinach were increased 22.7% and 22.2% over those of the control group. Sugar content of the treated spinach was increased by 37.5%, vitamin A, C, and B were increased 35.63%, 41.67% and 40.00%, respectively, above the levels of the control group. Niacin content was decreased by 7.69%. Of 33 elements analyzed in the spinach, 29 elements were increased by Agri-wave technology. The spinach was infected with "rot disease" in the control group while there was no disease present in the treated group. In greenhouse testing, the average weight of 3 species of lettuce treated by Agri-wave technology was increased 44.10% over that of the control group (P < 0.0001). The average weight of 3 species of lettuce by only sound and only fertilizer treated separately increased 29.92% and 16.19% above that of the control group (P < 0.0001). Sampling survey results in the field test were comparable to the above mentioned greenhouse test. The fresh weight of treated lettuce by Agri-wave technology was increased 41.67% over that of the control group (P < 0.0001). The fresh weight of treated lettuce by only sound and only fertilizer was increased 30.88% and 19.61%, respectively, over the control group (both P < 0.0001).
