Summary Glasshouse experiment was conducted to determine the effect of Manda 31 on shoot and root growth of corn at the Subtropical Field Science Center, University of the Ryukyus, Japan. The treatments of the experiment were W: water application (control . M-10: Manda 31 application at 100 ppm and M-5: Manda 31 application at 200 ppm. Manda 31 solution or water was applied to plants until the solution or water begins to drip from the plants, at 15- day intervals starting 2- to 3-leaf stage. Plant length, leaf area and leaf dry weight of corn were increased with the Manda 31 applied at 1OO ppm and 200 ppm. Shoot and root production of corn were significantly increased when Manda 31 was applied 3 to 5 times, as compared to control plants. Manda 31 applied only one time at early growth stage could not increase shoot and root biomass of corn remarkably. Manda 31 at 200 ppm was more effective on shoot and root biomass production of corn than at 100 ppm. Above results indicated that Manda 31 at 200 ppm could be applied 3 to 5 times for higher shoot and root production of corn.
