Many causes of the fall such as weather, disease and insects, soil, sugarcane variety, cultivation method and so on were conjectured by those who were concerned with sugarcane culture. As a member of the investigation team, the author made a statistical analysis to see if meteorological factors affected the brix fall. Results obtained are as follows : 1. The low field ref. brix in the beginning of October 1985 shows some indications that heavy rainfall and severe north-south wind direction shift in typhoons passed by the island both in 1985 summer considerably affected the brix. 2. Reasons for low field ref. brix in the beginning of October 1984 could not be explained by weather conditions in the preceeding summer. 3. According to multiple regression analysis, a little brix rise during October preceeding harvest time and the end of harvest time in both 1984/85 and 1985/86 harvest years shows considerable indications that weather in the period adversely affected the little brix rise. 4. From relatively high brix in Tarama-son near Miyakojima in recent years, it is conjectured that cultivation method (planting season, fertilization and care, variety, windbreak forest etc.) may affect much the brix.","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/20.500.12000/3892"}]},"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.
