This study empirically examined the effects of the participatory approach on the adoption of new crop varieties and agricultural practices. Particularly, we focused on the social network structure and examined how the introduced technologies diffused through networks in rural Ethiopia. Our empirical results indicate that if farmers knew and trusted fellow participants, the probability of adopting a new variety increased by 25 percentage points. However, this network had no statistical impact on the diffusion of new agricultural practices. We conclude that the participatory approach has great potential in the adoption of new crop varieties through the social networks of farmers in Ethiopia.
6 pages., ISSN: 2311-6110, via online journal., Agricultural universities invest substantial resources in postgraduate research that generate knowledge products. These are aimed at providing solutions to practical constraints impeding increased productivity in the agricultural sector, which plays a vital role in Kenya's economic development. Using a case study of Egerton University, this study aimed to determine the strategies most frequently used to share the generated knowledge products, and to find out their preferences of the knowledge sharing strategies in use. The actors' perception of the relevance and accessibility of the knowledge products generated at the University was also examined. The study was conducted through desktop study which reviewed the Masters and Doctorate Theses that targeted livestock value chain actors generated between January 2005 and December 2011. A survey was conducted using structured questionnaires to collect data from a sample size of 198 actors. The findings indicated that the knowledge products were 25 to 29 times more likely (P<0.001) to be disseminated through the library than any other sharing strategy examined. The sampled actors in livestock value chain perceived media briefs to be the most accessible with a mean of 4.26. The Masters Theses were perceived as more relevant to their needs with a mean of 4.07. The findings indicate that the livestock value chain actors were not fully utilizing the knowledge sharing strategies used to reach them. The study concluded that the defined primary beneficiaries of knowledge products from the university were not effectively reached.
13 pages., via online journal., Many rice farmers decide to spray insecticides based on their perception of potential damage and losses caused by pest species. Farmers generally overestimate the seriousness of the rice leaf folder from visible damage and apply insecticides early, and therefore, changing perceptions may help reduce the perceived benefits of unnecessary spraying. Farmers in Long An province, Vietnam, were motivated to ‘test’ a heuristic or rule of thumb, ‘insecticide spraying for leaf folder control in the first 40 days after sowing is not needed’, by the distribution of carefully designed communication media materials. The media reached 97% of the farmers in the study sites. Leaflets, radio drama and posters had the most effective reach. Thirty-one months after the media introduction, the number of insecticide sprays dropped significantly from 3.35 sprays per farmer per season to 1.56. The proportion of farmers spraying at early and late tillering and booting stages was reduced from 59%, 84% and 85% to 0.2%, 19% and 30%, respectively. Those who did not use any insecticides increased from 1% to 32%. Correspondingly, farmers' perceptions of leaf folder damage as indicated in a belief index, decreased significantly from 11.25 to 7.62. The proportion of farmers who believed that leaf folders could cause losses was reduced from 70% to 25%, as did those who believed that early season spraying was required, from 77% to 23%, respectively. Farmers' insecticide spray frequencies and the belief index were significantly correlated and were not significantly different between farmers who had attended farmer field school training and those who had not. The cost (insecticide and labour) saving was the most important incentive for farmers to stop early season spraying as cited by 89% of the farmers. A survey of 12 other districts in Long An showed that 82% of the province's 210000 households were reached. About 20% had not applied any insecticides, 77% had stopped early season spraying and the average number of insecticide sprays was 1.6 (compared with 1.55 in study sites). The approach was readily adopted by extension in 15 provinces that launched their own programmes, extending to the whole Mekong Delta of 2 million farmer households.

search through journal, The use of hypermedia techniques in agriculture is analyzed in view of its possibilities to make access to knowledge and information more comprehensible, and to accelerate and disseminate their transfer. A survey of hypermedia applications in agriculture is provided and the characteristics of such systems are reviewed in terms of information structure, contents, system architecture, user information browsing and support. Requirements, future possibilities, and limitations are finally discussed. (original)
