Experimental plots were setted the variety of amount of fertilizer and method of fertilization (Table. 1). The results obtain were as follows : 1. At the five year tests, the number of growing seedling were smallest in the control. Dead seedling ratio were higher in the control than the fertilized plot. 2. The growth of tree height ratio increased with increasing amount of fertilizer and fertilized times. At the five year test period, the percentage of tree height increase by fertilization were 150-200% of the control. 3. In the fertilized plot, the stand crown closed from third year, therefore it was considered that weeding times in the stand were able to cut times for labor saving. 4. The growth of diameter ratio increased with increasing amount of fertilizer and fertilized times.","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/20.500.12000/4394"}]},"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.
