Agriculture is an essential component of food security, sustainable livelihoods, and economic development in sub-Saharan Africa (SSA). Smallholder farmers, however, are restricted in the number of crops they can grow due to small plot sizes. Agriculture inputs, such as fertilizers, herbicides or pesticides, and improved seed varieties, could prove to be useful resources to improve yield. Despite the potential of these agriculture technologies, input use throughout much of SSA remains low. This paper aims to better understand the process of innovation diffusion through information and interaction processes at the individual, social network, and community levels. A total of 203 participants were surveyed using a semi-structured interview method in four rural communities located in the Mbale, Lira, Kabale, and Masaka districts of Uganda. Participants were asked about their access to information technologies, information sources via social network ties, level of engagement in the local community, and agricultural input use. Results indicate households with higher levels of information access through cell phone use and weak-tie information sources are more likely to use inputs. Significant findings also include the interactional effect of cell phones and weak ties on fertilizer adoption. This research could inform policy makers of cost-effective methods of disseminating agriculture information and encouraging innovation diffusion.
