Most studies related to thereclaimed tidelands have also focused on the rice cultivation . However , due to the recent changes in agricultural andenvironmental situations , there is a need to explore the feasibility of other crops , such as horticulture and forage crops onreclaimed tidelands ( Lee and Ahn , ２００３ ) . The objective of this study is to select a all‐year‐round optimum forage croppingsystem in the reclaimed tidelands of central regions of Korea .Materials and methods The experimental field was on Daeho reclaimed tideland(３７o N ,１２６ .４o E) which is located in Danjin‐Gun ,Chungnam , Korea . The dike construction for reclamation was completely in １９８６ . This trial was to study on cropping systemwhich were consisted of Sorghum ⅹ Sudangrass hybrid( S) ＋ Barley (B) , Sorghum ⅹ Sudangrass hybrid ＋ Italian ryegrass( IRG) ,Japanese millet( M ) ＋ Italian ryegrass , Whole crop rice( R) ＋ Barley and Whole crop rice ＋ Italian ryegrass . S and M were usedas summer crops . B and IRG were used as winter crops . The experiment was carried out on a saline silt loam soil with the pHof ７ .３５ and the content of total nitrogen , organic matter and available phosphate were ０ .４６ g / kg , ８ .２ g / kg and ７６ mg/ kg ,respectively . Each plot size was １５㎡ and three replicate with randomized complete block design .Results In cropping systems ,R ＋ I had the highest ( ５０ ,８０７kg / ha and １５ ,０６５kg / ha , respectively ) . while S ＋ B had the lowest(１７ ,２４７kg / ha and ５ ,２０９kg / ha , respectively ) . In summer crops , Sorghum of S ＋ B had the highest crude protein( CP) content(１２ .９％ ) , while Sorghum of S ＋ I had the highest total digestible nutrient ( TDN ) content ( ６６畅０％ ) . In winter crops , Italianryegrass of S ＋ I had the highest CP and TDN contents . In cropping systems , R ＋ B had the highest CP yield( １ ,２１４kg / ha) ,while R ＋ I had the highest TDN yield(９５５０kg / ha) .Figure 1 Dry matter yield o f crop p ing systems at reclaimed tideland(′04‐′06) .Table 2 Crude p rotein , NDF , A DF and TDN percentage o f crop p ing systems at reclaimed tideland .CroppingsystemSummer crop( ％ ) Winter crop( ％ )CP NDF ADF TDN CP NDF ADF TDNS ＋ B １２ 乙.９ ６９ Ζ.８ ３１ y.９ ６３ L.７ １０  .１ ６２ 篌.２ ２８ 乔.７ ６６ J.２S ＋ I １２ 乙.１ ５７ Ζ.４ ２９ y.１ ６５ L.９ １１  .３ ５２ 篌.４ ２６ 乔.６ ６７ J.９M ＋ I １１ 乙.６ ６９ Ζ.４ ３１ y.０ ６４ L.４ １１  .８ ５１ 篌.５ ２５ 乔.６ ６８ J.７R ＋ B ８ 换.５ ６２ Ζ.２ ３２ y.０ ６３ L.６ ７  .３ ６１ 篌.２ ２７ 乔.８ ６６ J.９R ＋ I ６ 换.３ ６５ Ζ.５ ３２ y.５ ６３ L.２ ６  .９ ５５ 篌.９ ３１ 乔.６ ６３ J.９倡 ) summer crop :′０４‐′０５ ,winter crop′０５Conclusions Whole crop rice had the highest dry matter yields among in summer crops and Italian ryegrass had the highest drymatter yield in winter crops .
