12 pages., Purpose
Pervasive use of poor quality seed remains an important reason for low yields throughout the developing world. We explore ways to increase the quality of the local stock of seed tubers among a sample of Ugandan potato farmers.
Design/methodology/approach: Using videos, we provide agricultural extension information on (i) how to select the best seed tubers and (ii) how to properly handle and store seed tubers until the next planting season. The relative effectiveness of the information interventions is tested using an individually randomized controlled trial where we model spillovers using a randomization-based framework for estimating causal effects under interference between units.
Findings: Especially the video on seed selection translated into increased awareness and adoption of recommended practices, increased probability of using improved inputs, as well as higher consumption.
Practical implications: Interventions aimed at improving seed quality are important in the absence of access to high-quality seed. Video messages are becoming increasingly useful as a complementary tool in agricultural extension.
Theoretical implications: Randomization-based inference can be used to take into account spillover effects in the analysis rather than the design phase of an experiment.
Originality/value: This is the first study to address seed quality of potato tubers in a real-world setting using videos.

22 pages., Via online journal., Purpose: This study explores the use of advisory services by farm managers and its linkages with the economic, environmental and social performance of farms.
Design/methodology/approach: Using cluster analysis we determined groups of farms according to their sustainability performance and explored the correlations between contacts with advisory services and a set of farm-level sustainability indicators.
Findings: There exist significant differences in the number of farmers’ contacts with advisory services across countries, type of farms, farmers’ degree of agricultural education, utilized agricultural area, legal type of farm ownership and economic size of the farms. We identified three groups of farms that have different sustainability performance, are different in farm characteristics and relate differently to advisory services. The number of contacts with advisory services is positively related to the adoption of innovations, the number of information sources utilized and the adoption of farm risk management measures. We find no clear linear relationship between advisory services and environmental sustainability.
Theoretical implications: This study derives hypotheses to analyze causalities between indicators of farm-level sustainability and advisory services.
Practical implications: Results suggest the importance of taking into account the heterogeneity of farming systems for the design, targeting and evaluation of advisory services. In addition, results confirm the importance of selection of indicators that can be used in multiple sites.
Originality/value: We used a harmonized indicator of advisory services and a harmonized set of farm-level sustainability indicators in nine different EU countries that could be used to evaluate the role of advisory services in the achievement of multiple objectives in different groups of farms in multiple sites.

2 pages., Via UI online subscription., Purpose: This paper examines extension practises of agricultural workers within the Egyptian government and the perceived barriers they face in implementing participatory approaches, identifying improvements required in research and extension processes to meet the real needs of Egyptian farming communities.
Design/Methodology/Approach: Key barriers for engaging in participatory extension were identified using content analysis of semi-structured interviews, surveys and focus group discussion of 37 government agricultural workers along with participant observation and review of existing literature.
Findings: The majority of workers surveyed understood basic participatory extension principles and desired to use these approaches. Changing from traditional ‘top down’ extension to systems that engage with farmers' needs at the community level is made difficult due to the aging and poorly functioning Village Extension Worker (VEW) network. Thus, it is far easier for the research driven extension programmes to use technology transfer models.
Practical Implications: Participatory extension relies on strong relationship building and open communication between farmers, extension workers, researchers, interest groups and policy-makers. The Egyptian government must properly establish and resource the pivotal role of VEWs within the extension system to meet its strategic aims of modernising agriculture, developing food security and improving the livelihoods of rural inhabitants.
Originality/Value: This paper captures the unique perspectives of government research, extension and education workers involved in agricultural development at a time directly after the 2010 revolution, when they were able to more openly reflect on the past and present situations.
