Manda 31 (fermented natural plant concentrate) derived from 50 plant materials is used for improving yield and quality of crops, vegetables and fruits. The experiment was conducted at the Agricultural Experiment Farm, Faculty of Agriculture, University of the Ryukyus, Japan in 2000-2001 to evaluate efficacy of Manda 31 with different rates of fertilizer ( N : P : K = 9 : 9 : 18 ) on growth and yield of turmeric. The treatments of the experiment were (1) F-1-W : water treated control plot with fertilizer at 133kg/ha, (2) F-1-M : Manda 31 treated plot with fertilizer at 133kg/ha, (3) F-2-W : water treated control plot with fertilizer at 200kg/ha, (4) F-2-M : Manda 31 treated plot with fertilizer at 200kg/ha, (5) F-3-W : water treated control plot with fertilizer at 266kg/ha and (6) F-3-M : Manda 31 treated plot with fertilizer at 266kg/ha. The fertilizer at the recommended rates was applied three times to soil at 60 day intervals starting 60-75 day after planting (DAP) and Manda 31 (0.01ppm) or water was applied five times to leaves at 30 day intervals starting 60-75 DAP. In both the glasshouse and field experiments, shoot and yield of turmeric were significantly increased by the application of Manda 31 as compared to control plant with the same fertilizer rate. In glasshouse experiment, Manda 31 treated plot with fertilizer at 133kg/ha obtained higher shoot and yield than control plot with the fertilizer at 200kg/ha. Shoot and yield in the Manda 31 treated plot with fertilizer at 133 or 200kg/ha were similar to that in the control plot with the fertilizer at 266kg/ha.
