Crop of barley

Barley production - effect of weather damage on quality and varietal purity

5 December 2013

Weather damage in barley is a common problem worldwide including the south coast of Western Australia (WA) where it is associated with the late spring/early summer rains.

Improving the best practice integrated weed management package 2013 trial report

8 January 2014

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

Dry sowing and delayed sowing – effect on wheat yield at Wongan Hills 2013 trial report

6 March 2014

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.

Lupin crop

Cucumber mosaic virus in narrow-leafed lupins

26 November 2013

Cucumber mosaic virus (CMV) is a seed- and aphid-borne virus that infects narrow-leafed lupins. It can also infect many other broad-leafed plant species.

Seeding rate influence on grain yield of lupin pasture crops 2013 trial report

14 February 2014

Lupin seeding rates may need to be higher for pasture crops to achieve the same target density as standard crops, as lupin establishment density where crops were sown into perennial grasses was 8-3

Barley yield and biomass production when pasture cropped over subtropical perennial grasses 2013 trial report

17 February 2014

Biomass production was greater and distribution of green feed over time wider for the pasture-crop compared to crop only or permanent pasture systems.

Deep seeding wheat to chase moisture 2014 trial report

7 October 2014

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.

Three plots in dry sowing seed depth trial taken on 5 July 2013 at Mullewa Research Annexe. On left is buffer of Mace sown dry at 50mm, in the centre is Magenta sown dry at 50mm and on the right is Emu Rock sown dry at 70mm.

Managing wheat varieties for dry seeding 2013 trial report

20 February 2014

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

Wheat in paddock

Wheat and barley varieties' response to nitrogen 2014 trial report

28 October 2014

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.

Comparison of tillage methods for lime incorporation, West Binnu 2016 trial report

17 October 2014

Using tillage to incorporate lime improves the rates of reaction and increases subsurface pH sooner than spreading lime on the surface alone.

Focus paddocks 2014 trial report

18 September 2014

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

Canola response to plant density at Mullewa 2013 trial report

20 February 2014

In stressed conditions canola yields and gross margins were reduced at plant densities above 20 plants per square metre (plants/m2).

Are early fungicide applications effective for yellow spot and septoria nodorum blotch in the low rainfall zone 2014 trial report

26 September 2014

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

Fungicide timing for control and yield loss from sclerotinia sclerotiorum in canola 2014 trial report

26 September 2014

For successful management of sclerotinia stem rot in most years it is critical to target fungicides at early stage of bloom (20-30%), but optimal timing can vary depending on the season, in particu

Is wheat or barley the best option for early sowing 2015 trial report

26 May 2015

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.
