Intercropping: Wheat-Lupin
PCDF
To evaluate intercropping potential for Wheat and Lupin.
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.
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.
