Common bean on-farm trial in Nicaragua

Description

Data from decentralized on-farm trials of common bean (Phaseolus vulgaris L.) varieties in Nicaragua over five seasons between 2015 and 2016. Following the tricot approach, farmers were asked to test three varieties of common bean randomly assigned as incomplete blocks of three varieties (out of 10 varieties) and assess which of those three had the best and worst performance in nine traits (Vigor, Architecture, Resistance to Pests, Resistance to Diseases, Tolerance to Drought, Yield, Marketability, Taste, and Overall Appreciation).
