This document contains instructions for how to use the Harvest Quality Vision module through out the growing season to determine fruitlet growth rates.

You will need the Harvest Quality Vision module to access this feature.

This process can be useful for predicting harvest dates, comparing growth rates between seasons, and estimating the peak size before harvest.

This is a destructive testing process that requires sample fruit be removed from the tree and scanned.

  Instructions

1. Pick fruit from the growing area or variety you wish to sample.

 

2. Place fruit on a flat surface to scan. For best results, scan outdoors in natural light and avoid reflective surfaces.

 

3. Set up a Harvest Quality Vision Event. Be sure to select the growing area/variety that corresponds to your sample. You can optionally use the comments or event categories to note the growth stage or the number of samples when the scan was taken.

 

4. Scan sample fruit. Multiple scans can be taken for one event – if you are attempting to scan a large amount of samples, simply split them up into smaller groups and scan them group by group.

 

5. When you’ve finished scanning, make sure the device is connected to wifi or a cellular network so the scans can upload. Results will return to your device when they have finished processing.

 

6. The ‘Size Over Time’ chart displays the average size of the fruit in the block for every day that an HQV event represents. The x-axis is the event date. The y-axis is the average size in mm.

The main blue line shows the estimated average size of fruit based on scans from the same block, with each point being the actual average size from a specific HQV event date.

 

The shaded blue area represents the size range of the fruit detected.
