The grass was grown on a calcareous soil, which is one of the typical soil calledJaagaruin Okinawa. Four plots were set up in the experiment for varing cutting intervals of 4,5,6 and 7 weeks. The grass was cultivated for two years from 1978 to 1979. The results obtained were summerized as follows : 1. The yearly yields showed remarkable increase with the length of cutting intervals, and reached to over 27 tons in fresh weight and 3.5 tons dry weight per 10a on the plot of 7 week interval. 2. The weight per tiller, the grass length, the number of leaves per tiller and leaf area per leaf increased with the 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 8 in the plot of 7 week intervals. From the results described above, it is considered that the yearly yields of napier grass increase with the length of cutting intervals up to 7 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/20.500.12000/4008"}]},"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.
