Van der Heijden said a major challenge she was interested in the avocado industry was "our notoriously poor ability to estimate crop loads at both an individual and industry-wide level".
"I have seen the negative impacts the inaccuracy of crop estimation has through the supply chain, and I would like to do something to try and ameliorate this. I got the idea from research being done in Australia on the use of NDVI (Normalised Difference Vegetation Index) for crop estimation in avocados."
Van der Heijden has come up with a digital crop estimation tool, which will be up against a biodegradable pot, an irrigation tool, plastic-free plants, and an environmentally friendly paper wrap for plants from other finalists.
The finalists are drawn from the winners of six horticultural sector competitions:
Horticulture NZ (fruit and vegetable sectors)
NZPPI - New Zealand Plant Producers Inc.
NZ Winegrowers
Amenity Horticulture supported by NZRA - New Zealand Recreational Association
NZ Flower Growers Inc / FLONZI
Registered Master Landscapers New Zealand
The finalists compete for a prize pool of over $55,000 including:
A $7500 travel and accommodation package for the winner
A $5500 Massey University study scholarship for the runner-up
The AGMARDT Market Innovation Project first prize of $5,000
The T&G Practical Components travel scholarship valued at $3,500
