Abstract
The project analyzes the role of information dissemination regarding new technologies and more efficient agricultural practices, and the potential bottlenecks extension services might face in their role of bridging the distance between the research institutions and the local farmers. We consider an ICRAF program targeting dairy producers in Uganda. The farmer trainer (FT) program focuses on dissemination of a set of practices to improve animal feeds and use them more efficiently. EADD trains volunteer farmer trainers, who in turn train other farmers in the production and use of the high-value animal feeds and feeding practices.
This study is aimed at estimating the overall impact of EADD farmer Trainer approach, as well as analyzing the impact of different variations of the Farmer to Farmer (FTF) extension approach. Three program variations are considered (the details may be changed as the study unfolds): First, in order to account for beneficiary heterogeneity a variation on customization of extension advice will be conducted. Here it is proposed that selected FTs will be trained to conduct needs assessment with their trainees and help them build individual action plans, focusing their effort on technologies / practices that are more appropriate to them. The second experimental variation, aimed at improving the quality of the information, will establish linkages of FTs with extension professionals who can provide tutoring and expert advice to FTs and monitor their activities. Finally, the third variation will focus on increasing FT incentives. Here a tournament will be organized by which the local community whose milk production increases most will be rewarded by a significant gift and/or social recognition.

Experimental Design
Experimental Design
The study takes advantage of an expansion of the farmer trainer program to 12 new sites in Uganda, starting from October 2014. The program is targeting to reach around 17.000 small holder farmers in rural area.
The sample consist to 3.400 farmers randomly selected among which, 600 will be farmer trainers. These 3.400 farmers will be randomly assigned to the three variations envisioned in the study (see abstract). The study is using a phase-in randomization as all the farmers should benefit to the program at the end of the intervention.
Experimental Design Details
Randomization Method
The final decision has not been made as it depends in particular on some operational details. Likely to be a mix of public lottery and randomization in office by a computer, dependending on whether one considers the main treatment and the three variations.
Randomization Unit
Randomization will take place at the community level (i.e. all the farmers that would be served by a given farmer trainer).
Was the treatment clustered?
Yes
Experiment Characteristics
Sample size: planned number of clusters
560 communities
Sample size: planned number of observations
3400 farmers
Sample size (or number of clusters) by treatment arms
180 controls, 380 treatment
3 variations randomized orthogonally among the 380 treatment (groups with 0, 1, 2 and 3 variations)
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Minimum detectable effect of main treatment (overall farmer trainer program, irrespective of variations): increase by 21% of a standard deviation on milk production. (Two-sided test at 5% level, with 80% power, and intra-cluster coefficient equal to 0.24)
