Aims

To assess the value of pre and post GS30 defoliation in spring germplasm grown in HRZ regions of different season lengths using 21st April sowing date.

Key messages

 There were no significant differences in grain yield as result of grazing Trojan at GS30 but yield was reduced when grazing was delayed to GS32 (second node).
 There was evidence of frost in the ungrazed plots indicating that the slightly earlier flowering period in the ungrazed was not disadvantaged which can often be the case when spring wheat is sown in mid-late April.
 The delayed grazing strategy (GS32) resulted in lower grain yield and higher screenings, however there was an increase in grain protein content.
 Grazing late at GS32 resulted in an increase in grain protein and correlates to the lower yield in this treatment.
