23. Detailed data!

24. 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.)

25. Available information Farmer preferences Weather Household characteristics Land parcel characteristics (soil)

26. Data analysis

35. 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
