The Gompertz function was applied as the site index curve to improve the existing yield model. From the model, we computed the stem volume, stand basal area, stand volume, and stand density of the test plots were using site index values derived using the new site index function. These stand aggregates were compared to the previous model. The results revealed that the statistical indicators used to evaluate the performance of the two models provided smaller values in the present model than in the previous model. This confirmed that the improved yield model had greater accuracy and precision than the previous model. The improved yield model could be applied to generate a new yield prediction table for teak plantations in Northeastern Thailand.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_30002_file35":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-06-18"}],"displaytype":"simple","fileDate":[{"fileDateType":"Issued","fileDateValue":"2017-03-17"}],"filename":"jircas_working_report85-_75-85.pdf","filesize":[{"value":"653KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"jircas_working_report85-_75-85","objectType":"fulltext","url":"https://jircas.repo.nii.ac.jp/record/2000303/files/jircas_working_report85-_75-85.pdf"},"version_id":"b1a7c861-4a0c-45ce-9b86-91c28f271fb3"}]},"item_30002_geolocation20":{"attribute_name":"位置情報","attribute_value_mlt":[{"subitem_geolocation_place":[{"subitem_geolocation_place_text":"Thailand"},{"subitem_geolocation_place_text":"タイ"}]}]},"item_30002_identifier_registration17":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34556/0002000303","subitem_identifier_reg_type":"JaLC"}]},"item_30002_language12":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_30002_publisher10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan International Research Center for Agricultural Sciences","subitem_publisher_language":"en"}]},"item_30002_relation18":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"en","subitem_relation_name_text":"Improvement of Utilization Techniques of Forest Resources to Promote Sustainable Forestry in Thailand"}],"subitem_relation_type":"isPartOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.34556/0002000291","subitem_relation_type_select":"DOI"}}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"book part","resourceuri":"http://purl.org/coar/resource_type/c_3248"}]},"item_30002_source_identifier22":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"1341-710X","subitem_source_identifier_type":"PISSN"},{"subitem_source_identifier":"AA11159468","subitem_source_identifier_type":"NCID"}]},"item_30002_subject8":{"attribute_name":"主題","attribute_value_mlt":[{"subitem_subject":"Non-linear regression model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Dominant tree height","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Site index","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Stand volume","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Stem volume","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Stand density","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Stand age","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_30002_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Improved Yield Prediction Model for Teak Plantations in Northeastern Thailand","subitem_title_language":"en"}]},"item_30002_version_type15":{"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_title":"Improved Yield Prediction Model for Teak Plantations in Northeastern Thailand","item_type_id":"40039","owner":"74","path":["1718084285672"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-18"},"publish_date":"2024-06-18","publish_status":"0","recid":"2000303","relation_version_is_last":true,"title":["Improved Yield Prediction Model for Teak Plantations in Northeastern Thailand"],"weko_creator_id":"74","weko_shared_id":-1},"updated":"2024-06-20T06:28:50.274324+00:00"}
