The grass was grown on calcareous soil, which is one of the typical soil in Okinawa. Four plots were set up in experiment for each cutting interval of 6,8,10 and 12 weeks. The results obtained were summarized as follows : 1. The yearly yields showed increase with length of cutting intervals, and reached to over 37 tons in fresh matter yield and 5.7 tons dry matter yield per 10a on the plot of 12 week interval in 1984. 2. The dry weight of a tiller, the grass length, the number of leaves per tiller and leaf area per leaf increased with length of cutting intervals, but decreased the number of tillers per unit area and leaf weight ratio. 3. The leaf area index (LAI) increased with the length of cutting intervals, showing more than 12 in the plot of 12 week interval. From the results described above, it is considered that the yearly yields of napier grass increased with length of cutting intervals up 12 weeks.","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/20.500.12000/3945"}]},"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.
