In order to make the microclimatic environment of the lysimeters the same as that of natural field, the lysimeters were set in a sugarcane field. 4 The sugarcane and the soil used in this investigation were variety N : Co, 310,and limetstone soil from Gusikawa city, Okinawa, respectively. 5 The measurement was begun in October, 1967,and ended in February, 1969. As the data for evapotranspiration, the averaged values of present measurement and those shown in Part I of this report were used. 6 As climatic factors, mean monthly temperature and maximum monthly temperature were used, referring to the Monthly Weather Review, Ryukyu Meteorological Agency. 7 As the growth rate of the sugarcane, value obtained by Kozin Kugai were used in this investigation. 8 The following relations between the mean monthly temperature (t_m), maximum monthly temperature (t_<max>), and evapotranspitation of sugarcane (d mm/day) were found. d=0.00516t^<2.087>_m d=1.23×(10)^<-5>t^<3.74>_<max> 9 These formulas should be applied to only the year following the year in which the sugarcane was planted. As the data were not sufficient, these constants may be variable. 10 The growth rate (mm/day) is a linear function of evapotraspiration (mm/day) in each period.","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/20.500.12000/4551"}]},"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.
