It has been reported that there is a negative correlation between K^+ and sucrose concentrations in sugarcane juice in Okinawa. On the other hands, pot experiments revealed that increasing levels of potassium sulfate (K_2SO_4) did not decrease sucrose concentration, indicating that sugarcane quality may be affected not only by K^+ but by other components of potassium fertilizer, such as Cl^\u2212 and SO_4^\uff1c2\u2212\uff1e. We thus conducted two pot experiments changing levels of KCl and K_2SO_4 to test this hypothesis. As potassium levels increased, irrespective of types of potassium fertilizers, K^+ and Cl^\u2212 concentrations in juice significantly increased, while SO_4^\uff1c2\u2212\uff1econcentration did not change much. In the first experiment, both KCl and K_2SO_4 enhanced sucrose concentration in August. In October and December, however, the relationships completely changed based on the potassium type: with an increase of potassium fertilizer, sucrose concentration decreased in KCl plots but increased in K_2SO_4 plots. Similarly, sucrose reduction was only seen with increasing KCl levels in the second experiment. These results suggest that Cl^\u2212 is the primary factor in sucrose reduction, suggesting that we may improve sugarcane quality by lowering KCl amount or using K_2SO_4 instead of KCl.", "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": "25", "bibliographicPageStart": "15", "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": "Vol48No1p15.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2016950/files/Vol48No1p15.pdf"}, "version_id": "0b6a82a8-ec22-4df5-b125-9aea21bb8b7b"}]}, "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 : \u7b2c1\u5831\uff0e\u5869\u5316\u30ab\u30ea\u304a\u3088\u3073\u786b\u9178\u30ab\u30ea\u304c\u30dd\u30c3\u30c8\u683d\u57f9\u30b5\u30c8\u30a6\u30ad\u30d3\u306e\u30b7\u30e7\u7cd6\u542b\u6709\u7387\u306b\u4e0e\u3048\u308b\u5f71\u97ff", "item_type_id": "15", "owner": "1", "path": ["1642838337053", "1642838412624"], "permalink_uri": "http://hdl.handle.net/20.500.12000/0002016950", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2019-01-22"}, "publish_date": "2019-01-22", "publish_status": "0", "recid": "2016950", "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 : \u7b2c1\u5831\uff0e\u5869\u5316\u30ab\u30ea\u304a\u3088\u3073\u786b\u9178\u30ab\u30ea\u304c\u30dd\u30c3\u30c8\u683d\u57f9\u30b5\u30c8\u30a6\u30ad\u30d3\u306e\u30b7\u30e7\u7cd6\u542b\u6709\u7387\u306b\u4e0e\u3048\u308b\u5f71\u97ff"], "weko_shared_id": -1}
