quality and sugar concentration was reduced only with increasing potassium chloride (KCl) levels, while potassium sulfate (K_2SO_4) had no adverse effect. To investigate the effects on sugarcane yield and quality under field conditions, two field experiments with different types and/or levels of potassium fertilizer were conducted. Three plots were set up applying the same amount of potassium as the conventional plot but with different kinds of fertilizer, KCl and potassium sulfate (K_2SO_4) in the first experiment. In all the plots, juice K^+ and Cl^\u2212 concentrations had significantly negative correlations with sugar concentration. The second experiment was consisted of seven plots changing types (KCl and K_2SO_4) and levels (0, 6, 18 and 60 kg 10a^\u003c\u22121\u003e) of potassium. Juice and soil K^+ and Cl^\u2212 concentrations were increased by increasing KCl doses. The relationships were not as clear as the first experiment, however, pol in cane decreased with an increase of juice K^+ and Cl^\u2212 concentrations. The plot treated with the highest KCl amount had the lowest pol in cane and millable cane yield, resulting in the lowest sugar yield. From these, it was concluded that K+ and Cl\u2212 could be harmful factors to sugar content under field conditions as well and both sugarcane yield and quality are negatively influenced in fields where K^+ and Cl^\u2212 are excessively accumulated. Less KCl should be applied in such areas for the quality improvement; and besides, we need to lower K^+ and Cl^\u2212 existing in the environments by other ways as well as fertilizer management practices.", "subitem_description_type": "Other"}, {"subitem_description": "\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u6c96\u7e04\u8fb2\u696d\u7814\u7a76\u4f1a"}, {"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": "AN0083297"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u6c96\u7e04\u8fb2\u696d"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicIssueNumber": "1", "bibliographicPageEnd": "56", "bibliographicPageStart": "45", "bibliographicVolumeNumber": "48"}]}, "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", "download_preview_message": "", "file_order": 0, "filename": "Vol48No1p45.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2016953/files/Vol48No1p45.pdf"}, "version_id": "aa41170c-f1b0-497c-92fe-2b2507c3e72f"}]}, "item_title": "\u65bd\u80a5\u7ba1\u7406\u3092\u901a\u3058\u305f\u30b5\u30c8\u30a6\u30ad\u30d3\u306e\u7cd6\u5ea6\u5411\u4e0a\u306b\u95a2\u3059\u308b\u7814\u7a76. : \u7b2c3\u5831\uff0e\u5869\u5316\u30ab\u30ea\u304a\u3088\u3073\u786b\u9178\u30ab\u30ea\u304c\u5703\u5834\u683d\u57f9\u30b5\u30c8\u30a6\u30ad\u30d3\u306e\u7cd6\u5ea6\u304a\u3088\u3073\u643e\u6c41\u6db2\u4e2d\u30a4\u30aa\u30f3\u542b\u6709\u91cf\u306b\u4e0e\u3048\u308b\u5f71\u97ff", "item_type_id": "15", "owner": "1", "path": ["1642838337053", "1642838412624"], "permalink_uri": "http://hdl.handle.net/20.500.12000/0002016953", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2019-01-22"}, "publish_date": "2019-01-22", "publish_status": "0", "recid": "2016953", "relation": {}, "relation_version_is_last": true, "title": ["\u65bd\u80a5\u7ba1\u7406\u3092\u901a\u3058\u305f\u30b5\u30c8\u30a6\u30ad\u30d3\u306e\u7cd6\u5ea6\u5411\u4e0a\u306b\u95a2\u3059\u308b\u7814\u7a76. : \u7b2c3\u5831\uff0e\u5869\u5316\u30ab\u30ea\u304a\u3088\u3073\u786b\u9178\u30ab\u30ea\u304c\u5703\u5834\u683d\u57f9\u30b5\u30c8\u30a6\u30ad\u30d3\u306e\u7cd6\u5ea6\u304a\u3088\u3073\u643e\u6c41\u6db2\u4e2d\u30a4\u30aa\u30f3\u542b\u6709\u91cf\u306b\u4e0e\u3048\u308b\u5f71\u97ff"], "weko_shared_id": -1}
