Última Participatory Evaluation of Integrated Pest and Soil Fertility Management Options Using Ordered Categorical Data Analysis AgEcon Rutto, Esther; De Groote, Hugo; Vanlauwe, Bernard; Kanampiu, Fred; Odhiambo, George D.; Khan, Zeyaur R.. During participatory rural appraisals, farmers at the Lake Victoria basin of Kenya and Uganda identified Striga, stemborer and declining soil fertility as three major constraints to maize production To reduce food insecurity, several innovative integrated technologies to address these constraints have been developed, including push-pull (maize intercropped with Desmodium and surrounded by napier grass), maize-soybean and maize-crotalaria rotations, and Imazapyrresistant (IR) maize seed coated with the herbicide. To let farmers evaluate the new technologies, 12 demonstration trials, comparing the different technologies, were established in four villages in Siaya and Vihiga districts (Western Kenya) and two villages in Busia (Uganda). These evaluations,... Tipo: Conference Paper or Presentation Palavras-chave: Farmers' preference; Technologies; Ordinal regression; Crop Production/Industries. Ano: 2006 URL: http://purl.umn.edu/25317 Classification and influence of agricultural information on striga and stemborer control in Suba and Vihiga Districts, Kenya AgEcon Njuguna, Esther M.; Amudavi, David Mulama; Khan, Zeyaur R.; Mbogoh, Stephen G.; Nyikal, Rose Adhiambo; Karugia, Joseph Thuo. This paper reports on findings of a study to examine the sources used by farmers in search of agricultural information on striga and/or stemborers control technologies and factors that influence acquisition of such information in Western Kenya region. A random sample of 476 households in Suba and Vihiga districts were interviewed and 15 information pathways were identified. Using principle component analysis (PCA) to derive few latent variables that encapsulate maximum variance in the pathways, two components (latent variables) proxying for ‘agricultural knowledge’ were extracted. Type I-knowledge (first component) loaded heavily with sources that had ‘group’ information searching. Type II-knowledge (second component) loaded heavily with sources...

Ano: 2008 URL: http://purl.umn.edu/52081 Determining smallholder farmers’ preferences for Push-Pull technology dissemination pathways in western Kenya AgEcon Murage, Alice W.; Amudavi, David Mulama; Obare, Gideon A.; Chianu, Jonas; Khan, Zeyaur R.. The push-pull technology (PPT) has widely been disseminated to control stemborer (Chilo partellus and Busseola fusca) and Striga weeds (Striga hermonthica and Striga asiatica) in maize fields in Kenya. This study examined farmers’ preferences for various dissemination pathways in order to proffer better targeting of resources in an optimal dissemination strategy. The pathways considered were public meetings (barazas), radio, farmer field schools (FFS), field days (FD), farmer teachers (FT), the fellow farmers (FF) and print materials. Using a weighted score index and ordered probit regression, the different pathways were sequentially ranked as FD, FT, FFS, FF, print materials, Radio, and barazas. Marginal effects from ordered probit showed that farmers had...
