Optimising cultivar x time of sowing in wheat and barley locations
Aims

To investigate optimum time of sowing for individual wheat cultivars with different maturities

Key messages

Barley yield is less sensitive to time of sowing than wheat and in this trial highest yields came from faster maturing cultivars sown in early-mid May
