We indicated that low soil productivity in Kenya would be caused by a small number of vesicular-arbuscular mycorrhizal (VAM) spores and low contents of minerals, especially N and P in the soils, due to soil erosion (Wamocho et al., 1997a). When soil samples were collected from 103 orchards in 25 locations representing 13 soil types and 4 regions (high rainfall lowlands, highlands, arid and semi-arid lands, and coastal lowlands) in Kenya, the number of VAM spores in the 25g soil was 200 and below in every orchard. Particularly, in more than 60% of these orchards the number of spores was less than 50 in 25g of soil. In Japan, the number of VAM spores is about 1,000 and more in spite of use of large amounts of chemical fertilizers and agrochemicals (Ishii et al., 1992; 1999). Therefore, we investigated the utilization of mycorrhizal fungi on agroforestry systems at Kitui pilot forest supported by Kenya/Japan Soc. Forest. Train. Project, JICA in the semi-arid regions of Kenya. The results obtained are as follows : 1. The kinds of VAM spores collected were Glomus caledonium, Glomus etunicatum, Glomus fasciculatum, 4 unidentified Glomus genera (2 black spores and 2 brown spores), Gigaspora margarita and one unidentified Scutellospora genus. The spores of Glomus genus were the most common among them. 2. although VA mycorrhizae were observed in every plant, the intensity of VAM infection varied among the kind of plants. In particular, high percentage of VAM infection was observed in several weeds (Cynodon nlemfuensis, Cyperus rigidifolius, Cyperus teneristolon, Dactylotenium aegyptium, Digitaria abyssinica, Euphorbia hirta, Imperata cylindrica, Killinga bulbosa, Panicum maximum, Setaria pumilla and Solanum incanium), cassava (Manihot esculenta), and some tropical fruit trees [Carica papaya, Mangifera indica, Psidium guajava, Tamarindus indica and 2 kinds of indigenous fruit trees (Pachystigma schunannianum and Sclerocarya birrea)]. Also, all the trees shown in Table 3 formed VA mycorrhizae. 3. When papaya seedlings inoculated with Glomus caledonium were transplanted to a pilot field, inoculated papaya trees showed both improved resistance to water stress and higher survival percentages as compared to non-inoculated ones. 4. A millet-cultivated soil medium was very effective as a VAM inoculum. In particular, the number of VAM spores in 25g soil samples increased from 51 to 705 after millet cultivation. When 27 kinds of nursery trees were inoculated with the millet-cultivated soil medium, VAM development was stimulated on even tree species colonized commonly with ectomycorrhizal fungi. However, the stimulation of VAM formation in the roots of Cassia (Sena) siamea, Melia volkensii, Terminalia prunoides, Vitex doniana and Zizyphus mauritiana was observed without VAM inoculation. These trees may contain great amounts of VAM stimulatory substances in the roots. Furthermore, the growth of nursery trees used was strengthened by the soil medium. In particular, increase in VAM colonization in the roots of Acacia aulococarpa, Carica papaya, Cordia oralis, Mangifera indica, Persea americana, Psidium guajaxa and Schimus molle reflected vigorous growth of these trees. The inoculation of VAM fungi and the application of charcoal will be also very useful for the production of nursery trees. 5. These results suggest that the use of VAM fungi can make a useful contribution to agroforestry systems in the semi arid regions of Kenya.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11189254","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13433954","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"石井, 孝昭","creatorNameLang":"ja"},{"creatorName":"イシイ, タカアキ","creatorNameLang":"ja-Kana"},{"creatorName":"Ishii, Takaaki","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000041182.pdf","filesize":[{"value":"4.2 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000041182.pdf","url":"https://kpu.repo.nii.ac.jp/record/4229/files/KJ00000041182.pdf"},"version_id":"6048c206-fa2c-425a-978a-a2e264145729"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"アグロフォレストリー","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper"}]},"item_title":"ケニア国の半乾燥地における菌根菌を活用したアグロフォレストリー(農学)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ケニア国の半乾燥地における菌根菌を活用したアグロフォレストリー(農学)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["361"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"4229","relation_version_is_last":true,"title":["ケニア国の半乾燥地における菌根菌を活用したアグロフォレストリー(農学)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-01-12T04:38:11.414138+00:00"}
