The soil type consists of marllike semidentsgray clay. Six plots of 9m^2 (3×3) were arranged dividing into three treatments-I : control, II : N-14 P-5 K-8 and III : N-9 P-9 K-18,and two duplications. Five hundreds grams of chemical fertilizer mentioned above was used 3 times per year to each plot. The cutting height of the plants was 25cm above the ground level. 1) The over-all mean of annual green yields of Leucaena (K72a) in 9m^2 was 89.4kg (14.9kg×6), which was 14.4kg higher than that of the first year. There was no fertilizer effects on the treatments and the blocks, and significant differences were not shown on them. The highest yields among the cutting frequency was shown in the 1st cutting, and the lowst in the 5th, and there were high significant differences among them. 2) The over-all mean of dry matter yields in 9m^2 was 21.7kg (3.6kg×6). Fertilizer effects and significant differences on the treatments and the blocks were not shown. However, there were high significant differences among the cutting frequency. The dry matter ratio for the green yields was 24.2% and it was higher specially in the seasons of fall and winter. 3) The over-all mean of daily gain (DG) of the green yields was 291.2g and significant differences were not shown on the treatments and the blocks. However, there were high significant differences among the cutting frequency, and specially the 2nd and the 3rd cutting were higher than the 1st and the 6th. The same results were obtained from the case of the dry matter yields and the stem length.","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/20.500.12000/3954"}]},"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.
