Abstract :万田31号は,50種類の植物素材を組み合わせ発酵させて作られたもので,作物,野菜,果物の収量と品質を高めることがすでに報告されている。ここでは,施肥量の違いによる万田31号の使用がウコン(Curcuma spp.)の生育,収量に及ぼす効果を知るために2000年4月から2001年2月にかけて,琉球大学農学部附属農場において実験を行った。処理区は(1)1ha当り施肥量(化成肥料N : P : K=9 : 9 : 185)133kgに水を散布した対照区(F-1-W),(2)施肥量133kgに万田31号を散布した処理区(F-1-M),(3)1ha当り施肥量200kgに水を散布した対照区(F-2-W),(4)施肥量200kgに万田31号を散布した処理区(F-2-M),(5)1ha当り施肥量266kgに水を散布した対照区(F-3-W),(6)施肥量266kgに万田31号を散布した処理区(F-3-M),を設け葉面散布を行った。肥料は,ウコンの植付け後60∿75日目から60日間隔で3回施肥し,万田31号(0.01ppm)は植付後60∿75日目から30日間隔で5回施用した。ガラス室での実験では,それぞれの施肥レベルで対照区に比較して万田31号の施用により,ウコンの地上部乾物重と収量は増加した(図1,2)。F-1-M区は,F-2-W区に比べ地上部乾物重と収量が増加した(図1,2)。また,F-1-M区とF-2-M区の地上部乾物重と収量は,F-3-W区と同程度だった(図1,2)。圃場実験では,各々の対照区より万田31号を施用した区で有意に地上部乾物重が増加した(図3,4)。また,F-1-M区とF-2-W区およびF-2-M区とF-3-W区を比較すると,F-1-M区,F-2-M区で各々地上部乾物重及び収量が増加し,有意差が認められた。また,F-2-M区とF-3-M区を比較すると地上部乾物重および収量に差が認められなかった。このことから圃場実験では,肥料を200kg/haと万田31号(F-2-M区)の組合せがウコンの生育および収量の増加に大きな効果を示した。以上の実験結果から,万田31号の施用は肥料の利用効率を高めたことが考えられ,万田31号を施用することにより,化成肥料の施肥量を軽減し,環境調和型農業に寄与し得ると考えられる。
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. In field experiment, significantly increased shoot and yield were obtained by the application of Manda 31 in the plot with fertilizer at 133 or 200kg/ha as compared to that in the control plot with fertilizer at 200 or 266kg/ha, respectively. Similar shoot biomass and yield were recorded in the Manda 31 treated plots with fertilizer at 200 and 266kg/ha. Field experiment indicated that Manda 31 was more effective with the fertilizer at 200kg/ha in increasing turmeric yield. Manda 31 may enhanced the plant to use fertilizer properly for higher yield. Over all results of this study indicated that Manda 31 may reduce the amount of chemical fertilizer application in agriculture.
