Manda 31 is a fermented natural plant concentrate, which improves turmeric yield. The experiments were conducted at the Agricultural Experiment Farm, Faculty of Agriculture, University of the Ryukyus, Japan in 1999-2000. Experiment I was conducted to determine proper application interval of Manda 31 for better economic benefit in turmeric. In the experiment II, Manda 31 was applied to leaf, soil or both leaf and soil to evaluate growth and yield of turmeric. Growth parameters, shoot biomass and yield (rhizome dry weight) of turmeric were significantly increased with Manda 31 applied at 7,10,15,20 or 30 day intervals as compared to control in both glasshouse and field experiments. Yield was not significantly different among the Manda 31 application intervals, which suggested that Manda 31 should be applied at 30 day intervals for better benefit in turmeric cultivation. Manda 31 applied to leaf, soil or both leaf and soil increased turmeric yield by 15,15 or 19%. Leaf and soil application of Manda 31 resulted in the highest yield, which indicated that Manda 31 is absorbed by plants through leaves and roots. This result suggested that Manda 31 can be applied to both leaf and soil for better yield of turmeric., 紀要論文}, pages = {137--144}, title = {ウコン (Curcuma spp.) 栽培における万田 31 号(自然発酵植物凝縮物)の施用法に関する研究} }
