However, farmers' limited adoption and effectiveness of fertilizers, particularly for key upland crops other than maize, has not been adequately investigated. Using data from a multi-season survey of smallholder crop production in central Burkina Faso, this paper examines the yield response to farmers’ NPK fertilizer application and its cost-effectiveness compared to non-fertilization for sorghum and cowpea, two vital local food and cash crops. The findings reveal that farmers experienced yield responsiveness to compound fertilizer for sorghum and cowpea during seasons with relatively favorable rainfall. However, similar responsiveness was not observed in seasons with poor rainfall. In neither season was the net income of the fertilized crops found to be superior to that of the non-fertilized crops. Due to limited fertilizer use efficiency, the yield gains appear insufficient to offset the cost of fertilizers, regardless of some rainfall variability. Nevertheless, our analysis suggests that significant increases in net income cannot be achieved solely by reducing fertilizer costs; substantial yield improvements are also necessary. Therefore, in addition to fertilizer price reduction measures such as subsidies, innovative strategies are needed to enhance profitability and incentivize farmers’ fertilizer investments, including the implementation of effective agronomic practices that complement fertilization and marketing approaches designed to boost crop sales.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"Chapter 2: Issues and model-based optimization of smallholder technology adoption in upland cropping systems : Case of fertilization technology in central Burkina Faso","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":"2025-04-03"}],"displaytype":"detail","fileDate":[{"fileDateType":"Issued","fileDateValue":"2025-03-28"}],"filename":"jircas_working_report94-_39-46.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"jircas_working_report94-_39-46","objectType":"fulltext","url":"https://jircas.repo.nii.ac.jp/record/2000778/files/jircas_working_report94-_39-46.pdf"},"version_id":"6ef4e201-a200-4c4f-b111-c36aa77de300"}]},"item_30002_funding_reference21":{"attribute_name":"助成情報","attribute_value_mlt":[{"subitem_award_numbers":{"subitem_award_number":"JPMJSA1609","subitem_award_uri":"https://doi.org/10.52926/JPMJSA1609"},"subitem_award_titles":[{"subitem_award_title":"Science and Technology Research Partnership for Sustainable Development (SATREPS) : Project on the establishment of the model for fertilizing cultivation promotion using Burkina Faso phosphate rock","subitem_award_title_language":"en"}],"subitem_funder_identifiers":{"subitem_funder_identifier":"https://doi.org/10.13039/501100002241","subitem_funder_identifier_type":"Crossref Funder"},"subitem_funder_names":[{"subitem_funder_name":"Japan Science and Technology Agency (JST)","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"}]}]},"item_30002_identifier_registration17":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34556/0002000778","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":"Application of farm management models for decision support to smallholder farmers in sub-Saharan Africa"}],"subitem_relation_type":"isPartOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.34556/0002000771","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_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2-1.
