Tall fescue were mutually planted at 10cm intervals with dallisgrass (Paspalum dilatatum Poir.) and bahiagrass (Paspalum notatum Flugge), respectively, in autumn 1978,and they were treated by 2-week cutting and 4-week cutting intervals from April to October in 1979. Dry matter yields, number of tillers, tiller appearance, dead tillers, relative light intensity, total nonstructural carbohydrate (TNC), and root weights were examined following each cutting treatments. For tall fescue with 2-week cutting intervals yields, rate of growth, number of tillers, TNC contents and root weights, were lower than those with 4-week cutting intervals, but number of tiller appearance and dead tillers of tall fescue with 2-week cutting intervals increased remarkably in June and the middle and latter part of July. During experimental periods number of dead tillers for tall fescue was more a marked increase than of tiller appearance, resulting in many stubbles death of tall fescue. In tall fescue mixed with bahiagrass dry matter yields, number of tiller appearance and number of dead tillers were higher than those mixed with dallisgrass in each cutting treatments. Relative light intensity within pasture which was cut 2 weeks intervals was higher than that which was cut 4 weeks intervals. It appears that 2 weeks cutting caused lower growth rate of tall fescue than other, as a result of increase in number of tillers death and decrease in TNC content of stubbles after July. Number of stubbles death of tall fescue mixed with bahiagrass were more than those of tall fescue mixed with dallisgrass, which was due to the death of tillers from the middle and latter part of July to the end of September. Therefore, we found that 2-week cutting intervals affected the growth, especially death of tillers, of tall fescue mixed with tropical grasses.","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/20.500.12000/3946"}]},"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.
