LAMK.) in Malaita, Solomon Islands, where it is\ncultivated under warm wet tropical conditions year round; and upland rice (Oryza sativa L.) farmed by the Karen\nswiddeners over the intensive monsoon period in North Thailand. Field data including those based on time and\nmotion studies were collected through quantitative surveys during four periods on Malaita, between 1989 and 1995\nand continuously from 1972 and 1974 in North Thailand. Working within a broad ecological framework.\ninformation was collected from farmers on how much time they gave to cultivation of one hectare of land from\nthe point when it was cleared of relatively low growth fallow forest to harvesting of the crop. Malaita farmers did\nnot impress me as very strenuous workers and my data confirmed this. The Malaita gardeners invested 2.4 times\nmore time into a specific area of land during crop production. However, when labour input was measured against achieved calorific output, an apparently contradictory result was obtained. The calorific yield of sweet potato per\nhectare far exceeded that of upland rice. According to a model calculation, the ratio of labour input required to\nmeet the respective necessary minimal calorific needs for one adult between Malaita and North Thailand is nearly\n1:2. In other words, when measured based on calorific value of the principal staple crop, upland rice farmers have\nto invest twice as much time as potato farmers in securing their staple food requirements. Furthermore, another\nunignorable factor is that the climatically `always warm and rainy' conditions of Malaita make it possible for the\nlabour input to be evenly distributed throughout the year, thus allowing farmers to avoid crowding of their input\ninto one particularly busy season.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_6_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_6_relation_32":{"attribute_name":"関連（relation）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://hdl.handle.net/10232/15417","subitem_relation_type_select":"URI"}}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09160752","subitem_source_identifier_type":"PISSN"}]},"item_6_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN10088628","subitem_source_identifier_type":"NCID"}]},"item_6_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_6_text_44":{"attribute_name":"備考","attribute_value_mlt":[{"subitem_text_value":"Has errata: http://hdl.handle.net/10232/15417"}]},"item_6_version_type_14":{"attribute_name":"著者版フラグ","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":"Nakano, Kazutaka","creatorNameLang":"en"},{"creatorName":"ナカノ, カズタカ","creatorNameLang":"ja-Kana"},{"creatorName":"中野, 和敬","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-31"}],"displaytype":"detail","filename":"AN10088628_v32_n2_p71-103.pdf","filesize":[{"value":"96.1 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN10088628_v32_n2_p71-103.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/10976/files/AN10088628_v32_n2_p71-103.pdf"},"version_id":"4a378796-0b4e-4959-942e-b864eacb1fb1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Karen","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Kwara'ae","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Malaita Island","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sweet potato (Ipomoea batatas (L.)
