Technologies for Forecasting Tree Fruit Load and Harvest Timing—From Ground, Sky and Time

Nicholas Todd Anderson, Kerry Brian Walsh, Dvoralai Wulfsohn
2021 Agronomy  
Current practice estimates orchard fruit load based on the qualitative assessment of fruit number per tree and historical orchard yield, or manually counting a subsample of trees.  ...  The use of machine vision for flowering estimates, fruit sizing, external quality evaluation is also considered. The potential synergies between technologies are highlighted.  ...  D.W. is linked to Pronofrut, a provider of yield estimation services in Chile and Spain.  ...

An efficient RGB-UAV-based platform for field almond tree phenotyping: 3-D architecture and flowering traits

Francisca López-Granados, Jorge Torres-Sánchez, Francisco M. Jiménez-Brenes, Octavio Arquero, María Lovera, Ana I. de Castro
2019 Plant Methods  
Our method was useful for detecting the phenotypic variability of every almond variety by mapping and quantifying every tree height and volume as well as the flowering dynamics and flower density.  ...  Some of the almond varieties showed a significant linear fit between its crown volume and their yield.  ...  This is in agreement with [53] who lumped the yield and volume obtained using an on-ground LiDAR system together and obtained a linear relationship for a set of almond varieties of R 2 < 0.39.  ...
