Submerged damage Under submergence in the depth of 50cm, damage rate for a sugarcane of the average plant hieght of 60cm increases with the length of submerging time. For example, at submerging time of 12hrs, 24hrs, and 48hrs, the damage rates, in ratio to the non-submergence, although transitory, reaches to 10%, 32%, 42% respectively. As for the sugarcane of the average hieght of 160cm, damage of submergence was not observed in the depth of 50cm. Submerged damage in a fixed submerging depth is affected by the hieght of a sugarcane; the higher the sugarcane, the less the damage. 2. Excess-moisture injury The higher the ground-water level, the worse the growth of a sugarcane; In the groups of 5-cm-level, and 20-cm-level, an effect of excess-moisture injury was clearly recognized. In the groups of 5-cm-level, despite of the fact that the moisture on the surface of the soil is nearly in the state of saturation, an increase the number of tiller and the height of the sugarcane was recognized.", "subitem_description_type": "Other"}, {"subitem_description": "紀要論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "琉球大学農学部"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/4101"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "琉球大学農学部学術報告"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
