"subitem_description_type": "Other"}, {"subitem_description": "Fertilizer management practice is one of the factors that influence sugarcane quality. We focused on nutrients present in sugarcane juice, especially K^+ and Cl^\u2212 which were thought to be harmful to sugarcane quality from previous reports, and investigated relationships with pol in cane (PIC) to achieve a quality improvement through fertilizer management practices. Moreover, we examined the effectiveness of measuring juice electrical conductivity (EC) to easily estimate K^+ and Cl^\u2212 concentrations. From 2013 to 2015, we collected sugarcane samples from all of the sugar mills in Japan. Juice analysis over the three years showed that K^+ and Cl^\u2212 were the most abundant cation and anion in the juice and that both negatively correlated with PIC. K^+ and Cl^\u2212 concentrations significantly varied depending on production areas and those with higher K^+ and Cl^\u2212 concentrations had a low sucrose concentration. This finding suggests that sugarcane in those areas may have been supplied with these two ions in excess. EC always positively correlated with K^+ and Cl^\u2212 concentrations and the mean EC of samples with lower PIC than the standard value (13.1 to 14.3%) was 900 mS m^\u003c\u22121\u003e. EC may thus be a reliable indicator of K^+ and Cl^\u2212 concentrations and could be used for nutrient diagnosis because of its ease of measurement. For improving sugarcane quality, we recommend that potassium chloride, which supplies both K^+ and Cl^\u2212 and is a commonly used potassium fertilizer for sugarcane production in Japan, should be used in lower quantities in a year following one in which the EC of sugarcane juice at harvest is higher than 900 mS m^\u003c\u22121\u003e", "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": "AN00083297"}]}, "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": "44", "bibliographicPageStart": "35", "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": "Vol48No1p35.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2016952/files/Vol48No1p35.pdf"}, "version_id": "ac809e0b-51ee-44d3-a273-06dccf736748"}]}, "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 : \u7b2c2\u5831\uff0e\u30b5\u30c8\u30a6\u30ad\u30d3\u643e\u6c41\u6db2\u4e2d\u30a4\u30aa\u30f3\u3068\u7518\u8517\u7cd6\u5ea6\u306e\u95a2\u4fc2\u304a\u3088\u3073\u6804\u990a\u8a3a\u65ad\u3078\u306e\u643e\u6c41\u6db2\u5206\u6790\u306e\u5229\u7528", "item_type_id": "15", "owner": "1", "path": ["1642838337053", "1642838412624"], "permalink_uri": "http://hdl.handle.net/20.500.12000/0002016952", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2019-01-22"}, "publish_date": "2019-01-22", "publish_status": "0", "recid": "2016952", "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 : \u7b2c2\u5831\uff0e\u30b5\u30c8\u30a6\u30ad\u30d3\u643e\u6c41\u6db2\u4e2d\u30a4\u30aa\u30f3\u3068\u7518\u8517\u7cd6\u5ea6\u306e\u95a2\u4fc2\u304a\u3088\u3073\u6804\u990a\u8a3a\u65ad\u3078\u306e\u643e\u6c41\u6db2\u5206\u6790\u306e\u5229\u7528"], "weko_shared_id": -1}
