The following three issues are discussed. First, what extent is sugarcane significant as a rotation crop, and how is this related to its economic importance, such as income security for farmers? Second, what conditions is sugarcane important as a rotation crop? Third, is sugarcane the only crop that can be used in rotation (or can it be replaced by other crops)? The main analysis was carried out on Ie Island. The following points became clear. On the island, where horticulture and livestock farming are more prevalent, the area under sugarcane has been reduced, with sugarcane being planted every few years as a rotation crop. Sugarcane has always had some importance as a rotational crop, even on islands where it is the main crop. However, its importance as a rotational crop has increased as its importance for income security has decreased. In addition, while green manure crop can substitute for sugarcane in some cases, it is difficult to restore soil fertility in a short time with green manure crop on land with relatively poor land conditions, making sugarcane more critical as a rotation crop. Thus, in Nansei Islands, where crop choice is limited, as the economic importance of sugarcane decreases, its importance as a rotation crop increases, especially in areas with poor land conditions.","subitem_description_type":"Other"}]},"item_7_full_name_2":{"attribute_name":"著者よみ","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"サカイ, ノリオ"}]},{"nameIdentifiers":[{}],"names":[{"name":"ナイトウ, シゲユキ"}]},{"nameIdentifiers":[{}],"names":[{"name":"スギムラ, ヤスヒコ"}]}]},"item_7_full_name_3":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"SAKAI, Norio"}]},{"nameIdentifiers":[{}],"names":[{"name":"NAITOH, Shigeyuki"}]},{"nameIdentifiers":[{}],"names":[{"name":"SUGIMURA, Yasuhiko"}]}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"24321885","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040603","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_7_text_24":{"attribute_name":"公開者よみ","attribute_value_mlt":[{"subitem_text_value":"カゴシマ ダイガク"}]},"item_7_text_25":{"attribute_name":"公開者別名","attribute_value_mlt":[{"subitem_text_value":"Kagoshima University"}]},"item_7_version_type_14":{"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":"坂井, 教郎"}],"nameIdentifiers":[{"nameIdentifier":"142345","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内藤, 重之"}],"nameIdentifiers":[{"nameIdentifier":"142346","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"杉村, 泰彦"}],"nameIdentifiers":[{"nameIdentifier":"142347","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-03-24"}],"displaytype":"detail","filename":"AN00040603_v73_p1-16.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00040603_v73_p1-16","url":"https://ir.kagoshima-u.ac.jp/record/16578/files/AN00040603_v73_p1-16.pdf"},"version_id":"33b6e079-d5e6-4d4b-826c-284fe2a6346c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"さとうきび","subitem_subject_scheme":"Other"},{"subitem_subject":"輪作","subitem_subject_scheme":"Other"},{"subitem_subject":"伊江島","subitem_subject_scheme":"Other"},{"subitem_subject":"調整金","subitem_subject_scheme":"Other"},{"subitem_subject":"交付金","subitem_subject_scheme":"Other"},{"subitem_subject":"Sugarcane","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Crop rotation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ie Island","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Adjustment payments","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Subsidy","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":"輪作作物としてのさとうきびと南西諸島の農業","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"輪作作物としてのさとうきびと南西諸島の農業"},{"subitem_title":"Sugarcane as a Rotation Crop and Agriculture in Nansei Islands","subitem_title_language":"en"}]},"item_type_id":"7","owner":"29","path":["44","6115"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-03-24"},"publish_date":"2023-03-24","publish_status":"0","recid":"16578","relation_version_is_last":true,"title":["輪作作物としてのさとうきびと南西諸島の農業"],"weko_creator_id":"29","weko_shared_id":-1},"updated":"2024-01-30T05:23:36.408345+00:00"}
