Wheat canopy manipulation trial locations
Aims

To determine the effect of sowing rate and nitrogen fertiliser timing on crop canopy development, grain yield and grain quality.

Key messages

The slower development of MacKellar compared to Kellalac was associated with a higher tiller count in spring. However this did not translate to higher ear numbers, since with Kellalac 75% of tillers produced an ear, compared to 65% with
MacKellar (in Hamilton the opposite occurred).g/ha Sulphur.

Fungicide

All plots were sprayed on 27/10/03 with 1 application of Folicur ® at 290 ml/ha to control leaf rust.
All plots other than the F2 treatments were sown with 150 kg/ha Superphos (ON:15.7P:OK:5.8S), thereby applying 23.55 kg/ha Phosphorus and 8.7 k
