Corn: Attainable crop yields
What you should know about this indicator
- Attainable yields are more conservative than biophysical 'potential yields', but should be achievable using current technologies and management (e.g. fertilizers and irrigation).
- Attainable yields are based on assessments for the year 2000. Real attainable yield pre-2000 may be lower; and post-2000 may be higher than these values.

How we process data at Our World in Data
All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.
