Previous research indicated that limited soil water, especially in soils with an effective soil depth (ESD) of ≤ 50cm, restricts sorghum production under fertilized conditions. This finding suggests that optimal management practices, including fertilizer application rates, planting density, and variety selection, should vary by ESD. However, agronomic recommendations for sorghum in Africa have yet to incorporate ESD considerations. This study assessed the impact of ESD on optimal sorghum management practices and their economic stability amid fluctuating fertilizer prices. Two-year field experiments were conducted on soils with ESDs of 25, 50, and 100cm in the Sudan Savanna, Africa’s largest sorghum-producing region. These ESDs represent three dominant soil types in the region: two types of Plinthosols and Ferric Lixisol. Results showed that the optimal management practices varied by ESD: 37kg N ha－1, 3.1 hills m－2, and Kapelga for 25cm ESD; 74kg N ha－1, 8.3 hills m－2, and Kapelga for 50cm ESD; and 74kg N ha－1, 5.6 hills m－2, and Sariaso14 for 100cm ESD. These practices were economically robust for ESDs of 50 and 100cm but not for 25cm. A random forest regression model identified ESD as the most critical factor for sorghum yield, surpassing rainfall, nitrogen application rate, planting density, and variety. This study highlights the need for ESD-based agronomic recommendations to enhance food security and income stability for African farmers.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"Soil Science and Plant Nutrition (SSPN) is a peer-reviewed international journal and an official journal of the Japanese Society of Soil Science and Plant Nutrition (JSSSPN) -- description based on journal HP","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":"2025-07-03"}],"displaytype":"detail","fileDate":[{"fileDateType":"Issued","fileDateValue":"2025-06-26"}],"filename":"2000888.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"label":"2000888","objectType":"fulltext","url":"https://jircas.repo.nii.ac.jp/record/2000888/files/2000888.pdf"},"version_id":"83429e44-540c-4ae0-b14a-a7850d562ec8"}]},"item_30002_funding_reference21":{"attribute_name":"助成情報","attribute_value_mlt":[{"subitem_award_numbers":{"subitem_award_number":"04a1A2","subitem_award_uri":"https://www.jircas.go.jp/en/program/program_a/a2"},"subitem_award_titles":[{"subitem_award_title":"Development of intensive watershed management models for soil erosion-prone areas in Sub-Saharan Africa","subitem_award_title_language":"en"}],"subitem_funder_identifiers":{"subitem_funder_identifier":"https://doi.org/10.13039/501100009472","subitem_funder_identifier_type":"Crossref Funder"},"subitem_funder_names":[{"subitem_funder_name":"Japan International Research Center for Agricultural Sciences (JIRCAS)","subitem_funder_name_language":"en"}]},{"subitem_award_numbers":{"subitem_award_number":"05a1A6","subitem_award_uri":"https://www.jircas.go.jp/en/program/proa/a6"},"subitem_award_titles":[{"subitem_award_title":"Development of sustainable land management under extreme weather conditions in drylands","subitem_award_title_language":"en"}],"subitem_funder_identifiers":{"subitem_funder_identifier":"https://doi.org/10.13039/501100009472","subitem_funder_identifier_type":"Crossref Funder"},"subitem_funder_names":[{"subitem_funder_name":"Japan International Research Center for Agricultural Sciences (JIRCAS)","subitem_funder_name_language":"en"}]}]},"item_30002_geolocation20":{"attribute_name":"位置情報","attribute_value_mlt":[{"subitem_geolocation_place":[{"subitem_geolocation_place_text":"Burkina Faso"},{"subitem_geolocation_place_text":"ブルキナファソ"}]}]},"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":"Taylor & Francis","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_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1080/00380768.2025.2522832","subitem_relation_type_select":"DOI"}}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30002_rights6":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"© 2025 The Author(s).
