Not much to go on, but a good relationship with the group at EGC ( very friendly)

4. Sample
# of households 5009
# of producing households 2589
# of plots 4964
# of maize farmers 1386
# of maize plots 1565

5. Data good Crop management variables Fallow Wetness Soil depth
Soil colour
Soil type
Hours for drainage
Water
Tractor
Seeds (names of seed (MoFA, NGO, GM etc etc)

6. Data good 2
More specific on some questions such as labour and crop loss (men, children, women/ permanent/family)
More precise about whether a crop on a particular plot had fertilizer. I.e. fertilizer use is at the crop level not the plot level (Tanzania)
Specific on household assets
Crop loss
Where fertilizer came from
Covers two seasons, minor and major season
Transport data

7. Data good 3 Crop storage How it was stored
Was it treated by chemicals?
What percent of crop was lost in storage?
Was it lost to monkeys?

8. Percentage of farmers growing maize by district

9. Percentage of farmers using Inorganic fertilizer

10. Percentage of plots using Inorganic fertilizer

11. Number of crops grown per plot per district on average

12. National and regional averages
Maize output per plot
% plots with fert
% households with fert

20. Data bad
Areas - Piling effect!!

21. Data bad 2 Conversions – pain in the neck
Certainly not GPS!
Don’t know how much of the plot was what crop
Conversions – pain in the neck
Don’t know what kind of fertilizer (but question was asked)
GPS missing (soon to be sorted) – district problem, blank map spaces
Intercropping?
No seed application rate
