Final survey
At the end, so there is less time pressure
Together with collecting the observation cards (or photographing them)
Some very basic questions that may influence preferences (market orientation, age, gender, soil characteristics, etc.)
Available information
Farmer preferencesWeatherHousehold characteristicsLand parcel characteristics (soil)
Data analysis
What then?
Recommendations to farmers: which variety they should use
Recommendation to seed producers: what seed they should produce
Recommendation to breeders: what are gaps and needs to improve seeds
