It is an urgent matter to cope promptly with the abundant manure produced from the livestock production insouthern Kyushu of Japan , and one solution to these situations might be an operation of bio‐gas plant . However , the bio‐gasplant daily produces the digested effluent of manure (DEM ) solution , which assumes one kind of efficient �organic" fertilizer ,while the application of DEM solution to the tropical pasture remains to be assessed yet in Japan . Dwarf‐late (DL ) napiergrasspasture can be utilized permanently under the rotational grazing in Miyazaki , southern Kyushu ( Ishii et al . , ２００５) . This studywas conducted to determine the effect of DEM solution on the grow th and yield of DL napiergrass at the established year insouthern Kyushu .Materials and methods Dwarf‐late (DL ) napiergrass was transplanted at ２ plants /m２ （５０ cm × １００ cm) on May １０ , ２００７ . TheDEM solution was applied twice at ２７ and ６３ days after the establishment and twice after the first and second cuttings at ３levels ; ２ .４ , １ .２ and ０ .６ L /m２ / time ( ５ .０４ , ２ .５２ and １ .２６ g N /m２ / time) for H , M and L levels , respectively , and chemicalcompound fertilizer at １８ g /m２ / time ( ５ .０４ g N /m２ / time) was applied on the same day as a check ( C ) . The N ( NO３ － plusNH４ ＋ ) content of DEM solution was determined by ion‐analyser ( Model : IA‐３００ , Toa‐DKK Co . Ltd .) . The plots werearranged at ３ replications by a blocked design . Herbage yield was determined for ３ plants per plot by cutting plants at １０ cmand １５ cm above the ground level for the first and the second‐third cuttings , respectively .　 Figure 1 Relationship between annual totalo f dry matter y ield ( DMY ) and annualtotal o f N input in the dw arf‐latenap iergrass at the established year .DEM solution : ( ● ） H level , ( ■ ） M level ,( ▲ ） L level .Chemical compound f ertiliz er :(○ ） C level .Table 1 A nnual mean in p lant characters 倡 at the cutting o f the dwar f‐latenap iergrass .Cutting time Level PH( cm) TN( no ./m２ ) DMY( g /m２ ) PLB( ％ )I L ９０ 怂.５ ２８ 亖.７ １９６ N.７ ８１ ,.０( Aug . １４) M ９６ 怂.５ ３６ 亖.５ ２６０ N.５ ７９ ,.０H １０６ 忖.６ ４４ 亖.５ ３３０ N.９ ７６ ,.０C １０６ 忖.３ ３８ 亖.９ ３１１ N.２ ７２ ,.９II L ９１ 怂.０ ５９ 亖.６ １０９ N.４ ９２ ,.４( Sep . １８) M ９７ 怂.０ ７１ 亖.９ １５３ N.５ ９２ ,.１H １００ 忖.８ ８２ 亖.２ １７４ N.２ ９２ ,.０C １００ 忖.９ ８５ 亖.５ ２３９ N.２ ９１ ,.７III L ７６ 怂.５ ６４ 亖.２ １１２ N.０ ９０ ,.６( Oct . ２９) M ８８ 怂.０ ７６ 亖.２ １４７ N.５ ８７ ,.８H ９２ 怂.３ ８７ 亖.１ １６２ N.１ ８６ ,.０C １０１ 忖.１ ９０ 亖.１ ２６１ N.４ ８０ ,.３倡 PH : plant height , TN : tiller number , DMY : dry matter yield , PLB : percentage leaf blade .Results and discussion Plant characters , such as plant height , tiller number and dry matter yield , increased consistently with theincrease in DEM solution and the difference in plant grow th between H and C level was minimal , except for the third cutting( Table １) . Annual total of dry matter yield was closely correlated with the input of N supply ( r ＝ ０ .９２９ , P ＜ ０ .１０ ) ;irrespective of DEM solution and/ or chemical compound fertilizer ( Figure １ ) . Thus , DEM solution , produced from the bio‐gasplant , can be assessed as a rapidly effective �organic" fertilizer , as in the chemical compound fertilizer to dwarf napiergrass .Under the H level , dwarf napiergrass pasture can be supplied by ４ times of split‐application at ９６ kL (m３ ) / ha of DEM solutionfor the growing season ( June to October) .ReferencesDi , H .J . , Cameron , K .C . , Moore , S . , Smith , N .P . , １９９９ .
