qualified agricultural export commodity farmers in each of the selected EAs, which lasted
for two weeks. Through this exercise, relevant information on production, processing,
market channels, credit facilities, farm inputs and other agronomic indicators were
obtained from the farmers.
Supervisor/Quality Check
In order to ensure high quality data, two phase quality check exercises were put in place.
During the first exercise, the officers skim-checked and spot-checked ten listing forms
and ten selected holding questionnaires in the selected EAs in each State and FCT.
Farmers were randomly selected and visited on their farms to authenticate the data entries
made by enumerators.
