Uganda Legume Seeds Challenge Project



AgResults’ Uganda Legume Seed Project was designed as a six-year project using Pay-for-Results prizes to incentivize seed companies to produce and sell quality verified bean and soybean seed varieties to smallholder farmers across Uganda. The project closed early due to factors described below.


The learning journey

The problem

Seed Companies Ignore Legume Seed

Legumes are highly nutritious crops, and have the added benefit of improving soil health through nitrogen fixation. However, due to demand uncertainty, barriers to working capital, and opportunity costs, seed companies operating in Uganda do not focus on the legume seed market.

Contest design

Theory of Change

The project hoped that the prize incentive would spur Ugandan seed companies to increase investment in the production and marketing of improved legume seed, leading to increased adoption of improved seed by Ugandan smallholder farmers, particularly women who traditionally farm legumes. Increased use of improved seed would lead to better yields, meaning more income and increased household food security and nutrition.

Prize Structure

The Uganda Project employed a two-part prize: 1) access to cold storage (to mitigate against overproduction of seed), and 2) an annualized prize based on seed sales above a baseline.

Expected impact

Quality legume seeds are higher yielding, offering smallholders several potential benefits over local seed. First, legumes are a relatively inexpensive, high-protein food, so higher yields could mean higher consumption of this nutritious food category by smallholder farming households. Second, surplus production can be sold into the market, potentially increasing smallholder incomes. This is especially true of soybeans, which are often grown as a cash crop.

Actual results

The project closed early. However, the closure has led to a wealth of learning on what works and what does not.

Evaluation Design

The Uganda project has a nation-wide reach, so since a comparison or control group could not be set aside, the Evaluator is using a non-experimental performance evaluation (rather than an experimental or quasi-experimental impact evaluation) design to assess changes in key outcomes at the smallholder level. The Evaluator is also performing extensive qualitative research to better understand the mechanisms behind observed changes. To assess impact of the project on the market for quality legume seed, we are employing primarily qualitative research guided by the structure conduct and performance analytical framework.

Evaluation Stage

The Evaluator completed baseline data collection in 2017. The project was cancelled in 2018 and there are no plans for an endline because of limited activities under the project to influence the market or the legume seed value chain.
