Graph 1. Average wheat yields from 2023/24 FAR Cultivar Evaluation. FAR Autumn sown wheat and barley booklet 2023/2024.
Presented as a % of trial means – site mean yield for Canterbury was 12.2 t/ha and Southland was 10.8 t/ha.
SY Defiant has an excellent disease resistance profile with trials showing a low response to fungicide use. This makes it a low cost, low risk variety to grow along with low sprouting risk and early maturing. It can be sown from late March through to mid-July.
Ideal plant populations are March – April 150 plants/m2, May-June 175 plants/m2.
SY Defiant is a short stiff straw variety and will only need PGRs in high fertility, high yielding environments.
