A recent report indicates that between 2002 and 2003 rice consumption increased by 35.2%, and by 2005 production and consumption stood at 85,000 and 310,951 mts respectively, suggesting that the difference was imported amounting to about $170 million (CBIK, 2005). The low rice production can be explained on the one hand by the small farm sizes ranging from 0.5 acres to 2acres that farmers cultivate, attributed to lack of knowledge on appropriate crop husbandry practices, poor marketing, low yielding varieties, competition from other food crops and lack of cost effective equipment. Yet there is a potential area of 400,000 and 650,000 ha for upland and lowland/irrigated ecosystems respectively, and on the other hand by low average yields of conventional varieties, Dourado Precoce (1.5 ton/ha) and IR2793-80-1(3.5tons/ha) under rainfed and irrigated cultures, respectively in West Kenya. In the coastal region the conventional varieties grown include Kaiso K25, Parkisan, KR22 and KR 25 (Atera 2006) KARI and its partners have carried out NERICA adaptability tests focusing on yield and drought tolerance in 11 sites that resulted in selection of NERICA 11 and 4 that are being considered for release. Results have shown that the cultivars are drought tolerant, high yielding and have good cooking quality. The yields range from 2 to 3 tons per ha. Following the selection of NERICA 11 and 4, it is necessary to carry out analysis of the preconditions of diffusion as a strategy geared towards achieving high adoption rate. Moving into technology dissemination phase is a crucial stage in which it is important to understand the influence of socio-economic conditions. Preliminary results of the household survey carried out in Bungoma district indicated that there are a number of preconditions that can promote or hinder NERICA diffusion (Okech J N, Takeya H and Asanuma S, April 2006). The results include low interest in NERICA which is attributed to lack of information on its characteristics such as yield, tolerance to various stresses and taste. Other factors identified were perceived high cost of production, lack of experience, lack of appropriate equipment (rice mill), low competitiveness of local rice against imported rice in the domestic market and high-risk aversion. In addition while rice is ranked 9th compared to maize which is ranked 1st in land allocation, it is ranked 3rd in income generation priority scale. The preliminary study further revealed farmers obtain rice seed mainly from neighbor’s suggesting that there is no organized seed production system. Other preliminary results of the household survey in Kisumu and Busia indicated that we should consider differences between individual and group perception of constraints (opportunities) for dissemination of NERICA, and also think about the relation among NERICA and other crops.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"The proceedings included herein are the papers presented in the Seventh ICCAE Open Forum held in October 20th, 2006 at Nagoya University, Japan.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_9_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/17619"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/jouica.8.123","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学農学国際教育協力研究センター","subitem_publisher_language":"ja"}]},"item_9_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_9_source_id_7":{"attribute_name":"ISSN(print)","attribute_value_mlt":[{"subitem_source_identifier":"1347-5096","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"竹谷, 裕之","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"47553","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takeya, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"47554","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-20"}],"displaytype":"detail","filename":"6_body8.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"6_body8.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/15600/files/6_body8.pdf"},"version_id":"c0fd6b4d-aa60-45a7-9240-acfb1a5fb006"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ケニヤにおけるネリカ米普及に具備すべき社会経済的要素","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ケニヤにおけるネリカ米普及に具備すべき社会経済的要素","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"17","path":["1469"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-03-05"},"publish_date":"2013-03-05","publish_status":"0","recid":"15600","relation_version_is_last":true,"title":["ケニヤにおけるネリカ米普及に具備すべき社会経済的要素"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-11-13T02:59:38.476743+00:00"}
