The experiment was conducted to evaluate fertilizer effects on growth characteristics of redflower ragleaf. The treatments were nitrogen (N), phosphorus (P), potassium (K), nitrogen plus phosphorus (NP), nitrogen plus potassium (NK), phosphorus plus potassium (PK), nitrogen plus phosphorus plus potassium (NPK) and control (Con，no fertilizer). Nitrogen, P and K were applied at 200 (1.0g/pot), 100 (O.5g/pot) and 100 kg/ha (0.5g/pot), respectively according to the experiment design. Redflower ragleaf grown with the application of N, NP, NK and NPK was greener, and had higher SPAD value than the plants grown with the P, K and PK. Leaf defoliation naturally started earlier in the plants grown without N application. Plant height, leaf number and branch number were highest in the plants grown with the NPK followed by NK or N. The plants grown without N application resulted in earlier flowering. Fresh and dry weight of the plants was the highest when grown with the NPK followed by NK and N. Phosphorous and K applied separately or together did not show any positive effect on growth parameters, fresh weight and dry weight of the plant, but showed positive effect when applied with the combination of N. Combined application of N, P and K resulted in the best effect on all growth parameters, fresh weight and dry weight of redflower ragleaf.","subitem_description_type":"Other"},{"subitem_description":"ベニバナボロギクは、熱帯・亜熱帯地域の国々では機能性野菜として利用されている。本実験では、ベニバナボロギクの生長に対する化学肥料の影響を調査した。試験区は、チッソ(Ｎ)、リン(Ｐ)、カリウム(Ｋ)、チッソ＋リン(ＮＰ)、チッソ＋カリウム(ＮＫ)、リン＋カリウム(ＰＫ)、チッソ＋リン＋カリウム(ＮＰＫ)および無施肥(対照区)の8処理区とした。施肥量は、Ｎ、ＰおよびＫ、それぞれ20Kg/ha (1.Og/ポット)、1OOKg/ha(0.5g/ポット)およびl00Kg/ha(0.5g/ポット)とした。葉におけるＳＰＡＤ値は、Ｎ、ＮＰ、ＮＫおよびＮＰＫ区においてＰ、ＫおよびＰＫ区より高い値を示した。チッソ(Ｎ)を施肥しない区では、最も早く落葉が観察された。草丈、葉数および分枝数については、ＮＰＫ区で栽培した植物体に次いでＮＫとＮ区の植物体で高い値を示した。チッソ(Ｎ)を施肥しない区の植物体は、より早く開花することがわかった。全新鮮重および全乾物重では、ＮＰＫ区に次いでＮＫ区、Ｎ区の順に高い値を示した。リン(Ｐ)およびＫ肥料の単独施肥またはＰおよびＫの混合施肥によって、全新鮮重、全乾物重および生長形質への影響は認められなかった。ベニバナボロギクの栽培においてＮ、ＰおよびＫの組み合わせ施肥をすることが、生長形質や乾物重の増加に最も影響を及ぼすことがわかった。","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":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/26479"}]},"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.
