Trial Report Summary

Intercropping: Wheat-Lupin

Crop Type(s):
Wheat
Centre(s):
PCDF
Year(s):
2020
Collaborators(s):

PCDF

Objective(s):

To evaluate intercropping potential for Wheat and Lupin.

Project Findings:

The reliability of the results is low, due to the high percent CV for both wheat and lupin. The
overall yield is poor, relative to the five-year average for the Roblin area from 2014-2019 (59.6 bu/ac).
This was seen even in the check (42.6 bu/ac), suggesting a fertility error. Lower yields for lupin
intercrops is likely due to the lack of inoculant placed with the lupin. No lupin-specific inoculant was
available, and PCDF hopes to secure some lupin-specific inoculant for 2021.

Background:

Lupin is a leguminous crop that produces high protein seeds similar in shape and size to peas. As a
nitrogen-fixing crop, lupin makes a promising crop for a cereals intercrop. As with a pea-cereal intercrop,
the large seed size for lupin makes separating with cereals crops feasible, although cracks and chips can
be a difficulty.
