This trial has been running since 2018, and this paper reports results for 2020 and 2023. Annual yields exceeded 250 kg/a in 2022 and 200 kg/a in 2023. In 2023, sorghum yields were reduced due to sugarcane aphid insect infestation. Yields decreased especially on the northwest side of the field. The introduction of very early rye allowed more than three weeks between rye harvest and sorghum seeding. In 2023, sorghum yields were lower on the northwest side of the test plot. Nitrate nitrogen was reduced in the soil on the northwest side of the test plot. However, the association between reduced sorghum yield and reduced nitrate nitrogen could not be determined. Therefore, further investigation is needed to determine these causal relationships.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学農学部AFC報告 22 : 7-14, (2024)","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_10_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"春日, 重光","subitem_link_url":"https://soar-rd.shinshu-u.ac.jp/profile/ja.OFyaPUkh.html"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学農学部附属アルプス圏フィールド科学教育研究センター","subitem_publisher_language":"ja"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2433-8877","subitem_source_identifier_type":"EISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1291835X","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","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, 篤央","creatorNameLang":"ja"},{"creatorName":"Kobayashi, Atsuo","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"勝山, 優花","creatorNameLang":"ja"},{"creatorName":"Katsuyama, Yuka","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"竹田, 愛美","creatorNameLang":"ja"},{"creatorName":"Takeda, Ami","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"中野, 日陽","creatorNameLang":"ja"},{"creatorName":"Nakano, Hiyori","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"春日, 重光","creatorNameLang":"ja"},{"creatorName":"Kasuga, Shigemitsu","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available"}],"displaytype":"detail","filename":"AFC22-2.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://soar-ir.repo.nii.ac.jp/record/2002075/files/AFC22-2.pdf"},"version_id":"5a17e7b2-a5b2-4047-9332-cd712364636e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"輪作","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ライムギ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ソルガム","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"極早生","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ヒエノアブラムシ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"crop rotation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"rye","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sorghum,","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"very early maturing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sugarcane aphid","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":"未出穂型ソルガムと極早生ライムギによる輪作体系の乾物収量および栽培特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"未出穂型ソルガムと極早生ライムギによる輪作体系の乾物収量および栽培特性","subitem_title_language":"ja"},{"subitem_title":"Dry Matter Yield and Cropping Characteristics of a Crop Rotation System with Unearned Sorghum and Very Early Maturing Rye","subitem_title_language":"en"}]},"item_type_id":"10","owner":"16","path":["1711521976070"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-03-27"},"publish_date":"2024-03-27","publish_status":"0","recid":"2002075","relation_version_is_last":true,"title":["未出穂型ソルガムと極早生ライムギによる輪作体系の乾物収量および栽培特性"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2024-03-27T07:07:38.830245+00:00"}
