US & Canada Crop Spacing
Delivered June 4, 2020. Contributor: AAAlexandra
To inform the design of an autonomous weed picking robot by determining the range of crop spacing dimensions for carrots, onions and baby greens in commercial farm operations (at least 100 acres) in the US and Canada.
According to the University of Georgia, US commercial farms look to plant carrots in "
twin rows that are 2.5-3.5 inches apart.
Additionally, these sets of twin rows are placed
14 to 18 inches apart
Within each individual row, carrots are "
spaced 1.5 to 2 inches apart
" and at a depth that is no greater than
1/4 to 1/2 inches
Notably, these carrot planting standards do no appaer to vary by the variety of commercial carrot (e.g.,
apache, choctaw, vita sweet 691
According to the government of Saskatchewan, carrots are typically planted at the rate of "
10 to 16 plants per 30 cm (12 inches) of row
" for Nantes carrot varieties and "
12 to 18 plants per 30 cm (12 inches) of row
" for Imperator carrot varieties.
Additionally, inter-row spacing for carrots can range from "
41 to 76 cm (16 to 30 inches).
Meanwhile, commercial carrots are typically planted at a depth of "
1.9 to 2.5 cm (¾ inch to one inch)
