Although yield was increased and stabilized during that period, recent environmental concerns require minimization of P2O5 application. Six-year experiment on the effect of reduced  P2O5  application on growth and yield of paddy rice was carried out in Andosols area, where heavy P2O5 application had been continued. The experiment showed that growth and yield were not significantly influenced by reduced P2O5 application and that reduction by 25-50% compared to the present recommended application amount was safely practicable. Input and loss of available P2O5 in the soil was estimated to balance when P2O5 application is 4.6 kg/10 a. Since available P2O5 has been accumulated in the soil, drastic reduction of P2O5 application over the long term is possible without causing significant decline in yield and its stability by making most of the accumulated P2O5 stock.","subitem_description_type":"Abstract"}]},"item_13_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_13_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学農学部紀要. 44(1-2): 53-56 (2008)","subitem_description_type":"Other"}]},"item_13_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"Hagiwara, M","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.yhTePpkh.html"}]},"item_13_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学農学部"}]},"item_13_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0583-0621","subitem_source_identifier_type":"ISSN"}]},"item_1627890897769":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hagiwara,  M"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawamura,  S"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamamoto,  T"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-25"}],"displaytype":"detail","filename":"v44_09.pdf","filesize":[{"value":"529.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"v44_09.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/10509/files/v44_09.pdf"},"version_id":"aff3fa21-d4db-4ba5-a5f7-7d5f76461523"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Phosphate"},{"subitem_subject":"Phosphate Balance"},{"subitem_subject":"Andosols"},{"subitem_subject":"Paddy Rice"},{"subitem_subject":"Growth and Yield"},{"subitem_subject":"Reduction of Fertilizer Application"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Reduction of Phosphate Application in Paddy Rice Cultivation for More Sustainable and Environmentally Sound Agriculture","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Reduction of Phosphate Application in Paddy Rice Cultivation for More Sustainable and Environmentally Sound Agriculture","subitem_title_language":"en"}]},"item_type_id":"13","owner":"1","path":["1027"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-04-22"},"publish_date":"2008-04-22","publish_status":"0","recid":"10509","relation_version_is_last":true,"title":["Reduction of Phosphate Application in Paddy Rice Cultivation for More Sustainable and Environmentally Sound Agriculture"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:41:27.914500+00:00"}
