Researchers conducted a randomized evaluation in western Kenya to test how farmer participation in agronomic trials impacted their experimentation on their own farms with different input combinations and impacted their use of high-quality inputs, yields, adoption of new crops, and profitability. Farmers, particularly those with higher skills, who participated in the trials were quick to experiment and learn about different combinations of inputs and practices. However, their agricultural profits decreased across five agricultural seasons, possibly due to experimentation with new combinations of inputs and practices, while lower skilled farmers benefitted from higher skilled farmers' experimentation.
