Data were collected by teams consisting of a supervisor, between 2 and 4 interviewers and a data entry operator. The number of teams varied from state to state depending on the sample size or number of EAs selected. The teams moved in a roving manner and data collection lasted for between 20 - 30 days for each of the post-planting and post-harvest visits.
This survey used a concurrent data entry approach. In this method, the fieldwork and data entry were handled by each team assigned to the state. Each team consisted of a field supervisor, 2-4 interviewers and a data entry operator. Immediately after the data were collected in the field by the interviewers, the questionnaires were handed over to the supervisor to be checked and documented.
At the end of each day of fieldwork, the questionnaires were then passed to the data entry operator for entry. After the questionnaires were entered, the data entry operator generated an error report which reported issues including out of range values and inconsistencies in the data. The supervisor then checked the report, determined what should be corrected, and decided if the field team needed to revisit the household to obtain additional information.
The benefits of this method are that it allows one to:

i Capture errors that might have been overlooked by a visual inspection only,
ii Identify errors early during the field work so that if any correction required a revisit to the household, it could be done while the team was still in the EA.

As an additional aid to ensuring the good quality data, extensive monitoring was done of the field work Monitoring and evaluation guidelines and formats for fieldwork were developed. One (1) monitor was assigned to 2-3 states and all states and FCT, Abuja were covered. There were three levels of monitoring, the first and third were carried out by the state officers and zonal controllers while the second level were carried out by the technical team comprising National Bureau of Statistics (NBS) and Federal Ministry of Agriculture & Rural Development (FMA&RD) headquarters staff, and the World Bank .
The monitors made sure that proper compliance with the procedures as contained in the manual were followed, effected necessary corrections and tackled problems that arose. The monitoring exercise was arranged such that the first level took place at the commencement of the fieldwork,and the third level not later than a week before the end of the data collection exercise . In between these two, the technical team were embark on another round of monitoring throughout the country. While NBS state officers monitored in their state, the zonal controllers monitored in at least two(2) states (the zonal headquarters state and one other state of the same zone).
The 1st and 3rd rounds of the monitoring exercise lasted for six (6) days while the 2nd round by the technical team lasted for six (6) days, 2-4 states were covered at a time by an officer. Finally the third round of monitoring by State Officers/Zonal Controllers/Coordinators exercise were lasted for four (4) days. Monitoring instruments were developed and discussed during both training of trainers and zonal training.
