This trial examines the positive impact of crop competition, crop type rotation and the mouldboard plough on weed management.

Emu Rock and Corack were lower yielding than Cobra, Mace, Magenta and Wyalkatchem when sown dry and emerging in second week of May. Varieties sown in late May into moist soil were higher yielding.

Nitrogen (N) deficiency is the most common nutrient deficiency in wheat.

Establishing perennial pastures with precision guidance technology provides the opportunity to sow annual crops between perennial rows with tined seeders in future years.

Leaf spot diseases affecting wheat in Western Australia are septoria nodorum blotch, yellow spot and septoria tritici blotch.

Deep sowing to chase moisture can be critical in some seasons to getting crops established early. Wheat varieties differ in their ability to emerge from depth.

Which cereal or variety is more profitable to grow on wheat or canola stubble? There were nine trials conducted across the wheatbelt in 2014 addressing this issue.

Research was conducted into the yield and quality response of long season wheat and barley varieties to a range of sowing times between mid-April and mid-May at Esperance, Katanning and Dandaragan.

Deep sowing wheat (>100mm) will affect productivity.

Management of weeds, disease and nitrogen nutrition are ongoing challenges that limit yield potential.

Previous research in high rainfall zones or above average seasons has shown that in cases where leaf spot disease levels are high very early, fungicide application at or before first node (Z31) is

Magenta and Trojan are competitive with Mace when sown early to mid May, taking advantage of good conditions for grain filling.

The north east fringes of the Western Australian wheatbelt received good levels of summer rainfall in 2015.

The north east fringes of the Western Australian wheatbelt received good levels of summer rain in 2015.

Do our current wheat varieties need different management to get the best performance from them.

At Yuna, frost in September affected grain yield and quality of the short maturity varieties but not the longer maturing varieties Magenta and Calingiri.

In a high yield potential season, seeding wheat at 60kg/ha gave a higher yield and gross margin than seeding at 30kg/ha; but there was no further benefit in going to 90kg/ha.

The challenge in low rainfall areas is to understand the influence of management on the genetic difference of varieties.

The mean site yield was 1.4t/ha and there was no difference in yield between Mace and Hydra wheat.

Wheat agronomy research in 2014 at Eneabba aimed to determine how management with foliar fungicide and an in-furrow fungicide influenced the profitability of long season wheat varieties with an ear
