Automation and robotics in the cultivation of pome fruit: Where do we stand today?

Rafaël Verbiest, Kris Ruysen, Tanja Vanwalleghem, Eric Demeester, Karel Kellens
2020 Journal of Field Robotics  
The cultivation of apples and pears in orchards consists of several tasks that still demand much human labor.  ...  Besides an activity research in pome fruit orchards, this paper contains an overall review of the research and developments that have been performed to automate each major activity (e.g., pruning, thinning  ...  By using pressurized air, multispectral computer vision, and precisely positionable nozzles, it is possible to selectively blow floral buds away.  ...

Impact of postharvest deficit irrigation and organic amendments on sweet cherry production at newly and previously established orchards in the Okanagan Valley

Tirhas Mebratu Gebretsadikan
In the Okanagan Valley, sweet cherry production has expanded to higher altitudes due to climate change, but water availability and maintenance of soil health are major concerns for sustainable production  ...  Compost decreased arbuscular mycorrhizal fungi (AMF) colonization and increased total bacteria in soil, while fewer root P. penetrans were detected from incorporated compost alone or in combination with  ...  In some cases, however, PDI has had negative effects on productivity of fruit trees by reducing excessive vegetative vigor, and on flower bud induction and floral differentiation processes, for example  ...
