The model has been named the \"climatic productivity index of paddy rice\", and it might be used as the index of climatic productivity which gives potential productivity of paddy rice under given climatic conditions. In this paper the limit value of the index expressing the climatic productivity at the limit of its cultivation was investigated. Judging from both sides of northern limit and height limit, it seemed that the limit value of its cultivation, Y_＜po＞ = 500 was reasonable as far as the normal climate. In individual years, we could expect for more or less harvests (about 200kg/10a) at Y_＜po＞ = 500, assuming good cultivation conditions. In the years of cool summer damage the distribution of the index and the unit yield were illustrated, and in the regions less than the limit value, a great deal of damage including completely ruined harvests are anticipated. Finally, the movement of the limit line in the case of climatic variations was investigated.","subitem_description_type":"Abstract"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Department of Geography, Tokyo Metropolitan University"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00200173","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03868710","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"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":"Sugihara, Yasuyuki"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-04"}],"displaytype":"detail","filename":"20005-16-006.pdf","filesize":[{"value":"950.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20005-16-006.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/2759/files/20005-16-006.pdf"},"version_id":"f8e44ffe-21be-47e8-867a-d547c593b86f"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"A study on the limit of the paddy rice cultivation by means of the climatic productivity index","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A study on the limit of the paddy rice cultivation by means of the climatic productivity index"}]},"item_type_id":"3","owner":"3","path":["539"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-30"},"publish_date":"2010-11-30","publish_status":"0","recid":"2759","relation_version_is_last":true,"title":["A study on the limit of the paddy rice cultivation by means of the climatic productivity index"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T18:29:38.220351+00:00"}
