Enhancing the profitability and value of Class 1 New Zealand onions: Development of technologies for mapping onions at the field scale

This is a final report for “Enhancing the profitability and value of New Zealand onions”, a 3-year Sustainable Farming Fund project to understand the causes of variability in onion crops and provide industry with tools to monitor, map and quantify variability in yields and crop development. A methodology was developed to map developing crops and collect ground truth data to distinguish areas with different growth. A Management Action Zone (MAZ) concept to aid decision making was developed and tested.
