1) Farmers often do not report the crops which they planted but due to crop failure or other factors did not harvest. That is why it is important to include Q2. Depending on the purpose of your survey, decide whether such a crop variety should be included or not.
2) Keep in mind that many farmers practice crop rotation. Therefore, if you are interested in whether a given farmer grows a particular crop, you might need to ask for more than just the past one season. Assess the required recall period by interviewing local agriculture extension workers and more advanced farmers.
3) This indicator is suitable if you are interested in one crop only. For a complex overview of the different crops grown, use the Farm Diversity Score indicator.
4) Consider including an additional question assessing why the farmers who replied “no” to Q2 could not harvest the given crop (for example, due to floods, pests, other factors?).
5) Consider also including a question on where farmers accessed the seeds (or seedlings) of the given crop – this might help you to assess to what extent the production of the given crop can be attributed to your intervention.
6) If you are also interested in how much of the given crop was produced during the last season, use the Reported Agricultural Output indicator. For data on the crop’s yields, use the Reported Crop Yield Per Unit indicator.
