NZ Plant and Food Research and Massey University have developed a spreadsheet model for determining olive maturity. The decision of when to harvest is particularly challenging at the best of times, let alone in a year when the weather has affected flowering, fruit set, susceptibility to anthracnose etc, so this is a great aid for growers. The spreadsheets were emailed out to all members but are also available on the Olives NZ website http://www.olivesnz.org.nz/members-news/grower-manual/maturity-indicator-model-when-to-harvest/
