The evaportranspiration rate were mesured during the growing seasons 1967∿1968,1968∿1969,1970∿1971 and 1983,1984. The first three seasons involved summer planted sugar cane whereas the last two seasons involved spring planted ratoons. In order to estimate potential evaportranspiration modified Penman method, radiation method and pan method were used. It became clear that the curves of monthly mean crop coefficient of sugar cane increase smoothly for the first time, arive at peak and then decrease smoothly. The values of monthly mean crop coefficient differed a little from the estimation method of potential evaportranspiration. In Penman method, the peak values of monthly mean crop coefficient 1.0∿1.1 appeared during July to October. In radiation method, the peak values 1.1∿1.2 appeared during August to November. In pan method, the peak values 1.6∿1.8 appeared during July to October. It seems that the Penman method is better than other methods because of the peak growing season and the values of monthly mean crop coefficient.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_30002_file35":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"KJ00000161640.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2002889/files/KJ00000161640.pdf"},"version_id":"252f1160-b3bc-47ae-afda-293f67030e80"}]},"item_30002_identifier16":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3860"}]},"item_30002_language12":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_30002_publisher10":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"琉球大学農学部","subitem_publisher_language":"ja"}]},"item_30002_resource_type13":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30002_source_identifier22":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0370-4246","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN00250548","subitem_source_identifier_type":"NCID"}]},"item_30002_source_title23":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_source_title":"琉球大学農学部学術報告","subitem_source_title_language":"ja"},{"subitem_source_title":"The Science Bulletin of the Faculty of Agriculture.
