Abstract
There has been much optimism about the potential of information and communication technologies (ICTs) to provide agricultural extension services to remote households. Yet, little is known about how different communication methods fare, and, moreover, whether different segments of the population adopt information communicated via different means equally. We conduct a randomized control trial comparing the effectiveness of three ICTs — radio, voice response messages, and a smartphone app — with a traditional extension training in communicating fertilizer management practices across four districts in rural Nepal.

Primary Outcomes

Primary Outcomes (end points)
The main outcome variables of interest are :
a) farmer knowledge on which fertilizers and seeds they should optimally apply on their rice plots;
b) fertilizers applied on their rice plots (and potentially other plots to measure spillover effects?);
c) yields obtained on rice plots (and other plots?);
d) expected returns to improved fertilizer and seeds for rice;
e) trust of information coming from different sources.

Experimental Design

Experimental Design
In four districts in Nepal, we conduct a survey of all 105 cooperatives growing maize. From this survey, we randomly choose 15 cooperatives per district, totalling 60 cooperatives invited to participate in the study. Randomization of the treatment arms was done at the cooperative level: 10 cooperatives were randomly assigned to each of our four treatments. Twenty cooperatives were randomly selected into the control group in which farmers received no information on fertilizer application timing.
