Beauv.) is considered to be a noxious weed in northern Japan, and controlling its growth is difficult because of its aggressive spreading by rhizomes. We conducted field experiments on quackgrass to determine its forage productivity, quality and nutritive value for use as a forage crop. The mean annual dry matter yields during five years were 976-1,311kgDM/10a on meadow and 648-1,042kgDM/10a on simulated pasture. The fluctuation of seasonal productivity was small in comparison with other forage grasses. The persistency of quackgrass dominance in meadows was very high ; on the other hand, quackgrass coverage decreased gradually in pastures. After the boot stage, the total digestible nutrients (TDN) and crude protein concentration decreased. The rate of decrease in quackgrass was lower than that in orchardgrass. Quackgrass had an annual average TDN concentration of 59%, which was higher than Kentucky bluegrass (Poapratensis L.) and reed canarygrass (Phalaris arundinacea L.) and lower than orchardgrass (Dactylis glomerata L.) and perennial ryegrass (Lolium perenne L.) on grazing utilization.\n","subitem_description_type":"Abstract"},{"subitem_description":"東北地方に自生するシバムギ (Agropyron repens (L.) Beauv.) の収量性や永続性、栄養価を調査し、シバムギの飼料特性を評価して畜産的に利用する際の基礎的知見を得ることを目的とした。試験1ではシバムギ優占草地の生産量と永続性を採草条件と模擬放牧条件で刈り取り回数と施肥量を変えて5年間調査した。試験2では採草条件、試験3では放牧条件において栄養価を他草種と比較した。　試験1の結果、年間乾物収量の5年間の平均は採草条件では976-1,311kg/10a、模擬放牧条件では648-1,042kg/10aであった。シバムギは採草条件では純群落化し高い永続性を有すると考えられた。一方、強度の高い放牧条件では減少し、ケンタッキーブルーグラスやシロクローバの割合が高まると推察された。試験2では、シバムギの1番草は穂ばらみ期から結実期までの生育に伴う栄養価の低下が非常に緩慢であり、結実期にはオーチャードグラスと同等以上の栄養価であることが示された。試験3ではシバムギのTDN含有率の年間平均は59%程度でペレニアルライグラスやオーチャードグラスより低いものの、リードカナリーグラスやケンタッキーブルーグラスより高い栄養価をもつ草種である傾向が示された。シバムギは採草および肉用種繁殖牛の放牧用の草種として十分活用できる。\n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001212","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人 農業・食品産業技術総合研究機構 東北農業研究センター"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00001212","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-3379","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"八木, 隆徳"},{"creatorName":"ヤギ, タカノリ","creatorNameLang":"ja-Kana"},{"creatorName":"YAGI, Takanori","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"目黒, 良平"},{"creatorName":"メグロ, リョウヘイ","creatorNameLang":"ja-Kana"},{"creatorName":"MEGURO, Ryohei","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"福田, 栄紀"},{"creatorName":"フクダ, エイキ","creatorNameLang":"ja-Kana"},{"creatorName":"FUKUDA, Eiki","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-08"}],"displaytype":"detail","filename":"tarc_report_No108p63-71p.pdf","filesize":[{"value":"383.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"tarc_report_No108p63-71p.pdf","url":"https://repository.naro.go.jp/record/1245/files/tarc_report_No108p63-71p.pdf"},"version_id":"d43260c4-694b-4ad4-a59a-ed0ed1170de0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"シバムギ","subitem_subject_scheme":"Other"},{"subitem_subject":"収量","subitem_subject_scheme":"Other"},{"subitem_subject":"永続性","subitem_subject_scheme":"Other"},{"subitem_subject":"飼料成分","subitem_subject_scheme":"Other"},{"subitem_subject":"採草","subitem_subject_scheme":"Other"},{"subitem_subject":"放牧","subitem_subject_scheme":"Other"},{"subitem_subject":"Quackgrass","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Yield","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Persistency","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Feed composition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Meadow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Pasture","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"東北地方におけるシバムギ (Agropyron repens (L.)
