Researchers introduced a mobile phone-based agricultural extension service to evaluate its impact on knowledge and adoption of effective farming methods among cotton farmers in Gujarat, India. They found that the service was highly effective in nudging farmers to adopt a number of recommended agricultural technologies, like fertilizer, pesticide, and improved seed varieties, but had no measurable impact on farmers’ yields or profits.

Researchers randomly evaluated whether well-timed access to credit would allow maize farmers in Kenya to make better use of storage and sell their output at higher prices. The loan offers allowed farmers to store more maize and earn higher revenues, with larger revenue impacts for farmers granted loans immediately following harvest and in areas where a smaller share of farmers was offered loans.
