Mapping and results of the analysis about spot information on 100 fields set in Minami-Daito Island were reported in this paper. It was discussed whether the spot and surface indications could effectively represent the spatial distributions of the quality data, mineral compositions of cane juice and soil. There was an area with low sugar content year by year at the north district of the Island. Remarkable annual differences were observed within both sugar content and unit yield. Weather conditions were regarded as main factors. The degree of disasters by typhoon or drought, which exerted to all area of the Island, was not uniform. K content and P content in cane juice were related to the sugar content. The soil in the Island was generally acid soil, on the other hand, the values of pH in the fields post land reclamation were about eight. It was regarded as an effect of soil improvement. Thus, mapping of information with limited spots was effective to analyze and to improve the production system.","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"沖縄農業研究会"},{"subitem_1522300295150":"en","subitem_1522300316516":"Okinawa Agriculture Research Society"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"1344-1477"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00083297"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"沖縄農業"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2004-08","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicPageEnd":"20","bibliographicPageStart":"7","bibliographicVolumeNumber":"38"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"625.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2015653/files/625.pdf"},"version_id":"d9a061c6-ceab-4055-9880-06f75de681fe"}]},"item_title":"GISによるサトウキビ生産支援情報システムの開発　（第1報）　―点情報の表示と解析―","item_type_id":"15","owner":"1","path":["1642838331862","1642838412624"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-01-29"},"publish_date":"2009-01-29","publish_status":"0","recid":"2015653","relation_version_is_last":true,"title":["GISによるサトウキビ生産支援情報システムの開発　（第1報）　―点情報の表示と解析―"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T07:41:55.627416+00:00"}
