e0“Defoliation before stem elongation in two seasons of very low growing-season rainfall (<100 mm) caused no or very little loss in grain yields, which were generally <1 t ha–1.”

Other claims from this paper (6)
- Observation Barley varieties produced up to twice the dry matter of wheat or oats cultivars before defoliation.
- Intervention effect Mowing after stem elongation more than halved early maturing grain yield relative to no defoliation.
- Intervention effect Later maturing varieties had less grain yield loss from mowing after stem elongation.
- Intervention effect Long-season winter wheat grain yield was similar across defoliation timings.
- Observation Winter wheat had no yield advantage over defoliated spring cereals.
- Recommendation The authors suggest grazing cereals for winter feed in the low rainfall zone.
