Access to a weigh trailer was essential to the success of the test-as-you-grow trials conducted by the Kunjin TOPCROP group, although the high level of accuracy was the result of trial design as well as the use of the weigh trailer.
The trailer, built by the Kunjin group with support by growers through the GRDC, was used to weigh the harvest of an entire plot (10 m by 250 m) at a time. Although it is possible to measure grain yield with a yield monitor in the header, the weigh trailer provides important backup.
After each plot is harvested the grain is shifted into the weigh trailer, and the weight measured before the grain is shifted onto a truck or field bin. Grain quality samples can also be taken from the weigh trailer for subsequent testing.
