Because sparse planting can reduce the cost and labor for raising and transplanting seedlings, it could be used for the production of inexpensive rice. In the present study, we examined the effects of sparse planting on the yield and grain quality of‘Yamadawara’, a rice cultivar suitable for use in restaurant and frozen food industries. Sparse planting slightly decreased the yield, by only 2–6%, when the planting density was halved. This planting method significantly decreased the 1000-grain weight, suggesting that the decrease in grain size is closely related to yield reduction of‘Yamadawara’. Sparse planting was found to have various effects on the grain number per area and rate of mature grains depending on the cultivation years and nitrogen application conditions. The appearance quality and protein content of the grain was only slightly affected by this planting method. Therefore,‘Yamadawara’can be cultivated by sparse planting, but caution must be exercised to avoid excessive decrease in grain size.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00000233","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立研究開発法人 農業・食品産業技術総合研究機構"},{"subitem_publisher":"National Agriculture and Food Research Organization (NARO)"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00000233","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2432-809X","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":"小林, 英和"},{"creatorName":"コバヤシ, ヒデカズ","creatorNameLang":"ja-Kana"},{"creatorName":"KOBAYASHI, Hidekazu","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"長田, 健二"},{"creatorName":"ナガタ, ケンジ","creatorNameLang":"ja-Kana"},{"creatorName":"NAGATA, Kenji","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":"2018-03-28"}],"displaytype":"detail","filename":"warc_report18-1-11p.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"warc_report18-1-11p.pdf","url":"https://repository.naro.go.jp/record/253/files/warc_report18-1-11p.pdf"},"version_id":"a16c5e35-d108-47e1-83af-15b08def7fe8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"栽植密度","subitem_subject_scheme":"Other"},{"subitem_subject":"収量","subitem_subject_scheme":"Other"},{"subitem_subject":"水稲","subitem_subject_scheme":"Other"},{"subitem_subject":"千粒重","subitem_subject_scheme":"Other"},{"subitem_subject":"多収品種","subitem_subject_scheme":"Other"},{"subitem_subject":"品質","subitem_subject_scheme":"Other"},{"subitem_subject":"やまだわら","subitem_subject_scheme":"Other"},{"subitem_subject":"appearance quality","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"grain weight","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"high-yielding cultivar","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planting density","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"rice","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Yamadawara","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"yield","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":"業務・加工利用向け水稲品種「やまだわら」の収量と品質に及ぼす疎植の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"業務・加工利用向け水稲品種「やまだわら」の収量と品質に及ぼす疎植の影響"},{"subitem_title":"Effects of Sparse Planting on Yield and Grain Quality of the High-yielding and Palatable Rice Cultivar ‘Yamadawara’","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"11","path":["38","82"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-03-28"},"publish_date":"2018-03-28","publish_status":"0","recid":"253","relation_version_is_last":true,"title":["業務・加工利用向け水稲品種「やまだわら」の収量と品質に及ぼす疎植の影響"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-05-15T16:10:35.003538+00:00"}
