Abstract
What makes agricultural extension fail in developing countries? In particular, are agricultural extension services offered to the wrong people? Will technology diffuse faster if extension is offered to seed dealers rather than directly to farmers? These questions are important because agricultural extension is generally viewed as under-performing in developing countries. New and innovate approaches need to be tested in order to incrase the rate at which improved technologies diffuse to farmers. The improved technology being studied in the experiment is Swarna-Sub1, an improved rice variety that is nearly identical to Swarna (Eastern India's most popular rice variety). The difference between Swarna-Sub1 and Swarna is that Swarna-Sub1 is more flood tolerant. The objective of this study is not to test the efficacy of Swarna-Sub1, as this has been done in previous work. Rather, this study aims to test two alternative mechanisms to make Swarna-Sub1 diffuse faster.

Primary Outcomes

Primary Outcomes (end points)
The main objective of the intervention is to increase adoption. We will therefore measure adoption once during each of the next 3 seasons. These surveys will measure both agricultural practices and the types of seed varieties used by each farmer. Our main outcome of interest is whether the farmer is cultivating Swarna-Sub1, i.e. the seed that was distributed to testing either to farmers or dealers.

Experimental Design

Experimental Design
This is a randomized control trial carried out in 72 blocks of Odisha state of India. The blocks are located in the flood-prone areas of the coastal belt of Odisha. 36 of the blocks are "control" blocks. In each control block we will partner with local agricultural extension officers to identify up to 40 farmers to receive a minikit of Swarna-Sub1.
The extension model will be modified in the 36 treatment blocks. Based on a list of registered dealers in the state, we will identify up to 10 per block to receive the same seeds and information that farmers were provided in the control blocks. Dealers can test the seeds as they wish. The objective of this intervention is for dealers to learn about the variety's quality and then pass that information on to their customers. Importantly, dealers have the incentive to pass this information along, while farmers in the control group don't benefit directly from telling other farmers about the variety.

Sample size (or number of clusters) by treatment arms
36 of the blocks are "control" blocks, 36 are treatment. In each control block we will partner with local agricultural extension officers to identify up to 40 farmers to receive a minikit of Swarna-Sub1. In the 36 treatment blocks, we will identify up to 10 dealers per block to receive the same seeds and information that farmers were provided in the control blocks.
