Interviewer instructions

List the crops with their codes.. List all crops before going to 3-7

These questions request recording in detail the quantity, and the value of
chemical fertilizer used in the last 12 months, including urea-nitrogen, phosphate, potassium.
NPK and other chemical fertilisers. Urea is calculated as the standard Urea, 2 kg Sulphate urea =
1 kg Urea. When interviewing regarding the quantity used for each kind of plant, in fact many
households can’t remember how much has been used and for which plants, even if they only
respond about the amount of Urea, potassium.. which has been bought in the last 12 months...If
the interviewer faces this case, s/he has to calculate the amount used for each plant according to
the rule: Based on the proportion of the area planted to each plant. For example: in the last 12
months Mr Nam’s household has bought 75 KGs Urea to fertilise 600 m2
of rice, 100 m2
of sweet
potato and 50 m2
of cabbage. If we follow the above rule, then the total area fertilised with Urea
is 750 m2
in which rice area accounts for 80%, sweet potato makes up 13% and cabbage area
accounts for 7%. Calculation of urea for each plant is as follows:
- Urea for rice = 60kg (75 kg x 0,8)
- Urea for sweet potato = 9,8 kg (75 kg x 0,13)
- Urea for cabbage = 5,2 kg (75 kg x 0.07).
This method is also applied for other fertilisers.
If the interviewer faces difficulties in the above calculation method, the interviewer can
record the total fertilizer and values of each that is used the most.
