Table 3.

A comparison of collecting plant phenotypes in the field between the Avenger tractor and 1 well-trained summer student

Avenger tractor Summer student
Total collection time (h) 1.5 4.0
Plots sampled per hour 110 60
Measurements per plot 120 3
Traits per plot (simultaneous) 4 2
Total measurements collected 115,200 1440
Time to upload/process data (h) 6 2.5

These values are averaged over 6 collections from a 2.7 ha field with 240 experimental plots (12 × 1.02 m) over 6 irrigation basins
