Key Points
- Two trials were established in November 1st sown Optic barley in Wanganui, one with different N fertiliser timings, the other with a range of insecticide and fungicide combinations.
- In the N trial the highest yield (due to more ears and larger grains) was from the application soon after sowing.
- In the insecticide/fungicide trial yields and net returns were greatest from the highest input treatments of two insecticides and two fungicides.
- The higher inputs resulted in lower disease, more green leaf and larger grains.
