Abstract

To develop the management system for very early sown wheat crops in the central wheat belt of Western Australia.

Trial 90EB34 and 90EB35

Location: East Beverley Annex.

90EB34 3 times of sowing at fortnightly intervals after the 9th April, with 8 varieties of wheat.

90EB35, 4 times of sowing at fortnightly intervals after the 23rd April with 9 varieties of wheat.

Trial 90No77 - 90NO80

Location: York

Each time of sowing has a separate trial number, 90NO77 TOS 1, 90NO78 TOS 2, 90NO79 TOS 3 and 90NO80 TOS 4.

Trial 90NO81

Location: Goomalling

TREATMENTS: - 3 times of sowing 25/4/90, 31/5/90, 13/6/90 with 9 varieties of wheat (see below).

Fertilizers were 104 kg/ha of Super, drilled, and 104 kg/ha Urea topdressed IBS. - All times of sowing received 35 g/ha Logran (R) IBS and Sprayseed was used as the knockdown where needed.

The first time of sowing was severely sand blasted on 2 occasions, rep 3 suffered the least damage of all.

Trial 90NO84 - 90NO86

Location: Grass Valley

TREATMENTS: - 3 times of sowing 27/4/90, 28/5/90, 11/6/90 with 9 varieties of wheat (see below).

Fertilizers were 154 kg/ha Super, drilled, and 104 kg/ha Urea, topdressed IBS. - All times of sowing received 35 g/ha Logran (R) IBS.

Very patchy germination in the 1st time of sowing and grubs (cut worm and/or web worm) may have thinned the plant density considerably.

Trial 90NO87-90NO89

Location: Wyalkatchem

TREATMENTS: - 3 times of sowing 24/4/90, 13/6/90, 22/6/90 with 9 varieties of wheat (see below).
