P4/S9 and P2/S4 were the two most profitable sequences and, overall, the 'maximum profit - P4' philosophy had the highest mean gross margin... It is logical that those growers that have chosen to have no livestock will have no interest in trialling grazing crops... Overall, the data has indicated that for the biserrula inoculant all of the carrier's have difficulties in carrying enough live rhizobia numbers to adequately nodulate the legume hosts after 3-4 months of dry, hot soil...

Mission - Through the establishment of an industry funded, not-for profit Company, implement a recognised, accountable, transparent and sustainable wheat classification system designed to maintain and grow the quality reputation of the Classes of Australian wheat... National APH Classification Regional classificat...
GRDC Taxonomy:
Varieties differ in their response to management inputs, especially for the important grain receival traits hectolitre weight, screenings and grain brightness... Screenings of plump grained varieties is generally less sensitive to delays in seeding date or increases in applied N than the screenings of narrow grain varieties... Example of differences in the screenings (% < 2.5 mm) response of 4 varieties (Bass, Baudin, Buloke and Vlamingh) to increasing N fertiliser application for two locations where the V x N interaction was significant: (L) Wittenoom Hills, 2010 and (R) Yerecoin, 2011...
GRDC Taxonomy:
Soil acidity remains a major constraint to productivity in the WA wheatbelt... The use of agricultural lime is increasing but, overall, application remains well below the amount required to achieve recommended targets for soil pH... We have estimated that 2.5 million tonnes of lime is required each year for the next ten years to recover soil pH and address ongoing soil acidification...
GRDC Taxonomy:
Impact of soil inversion, soil dilution and claying on non-wetting sandplain soils Stephen Davies, Peter Newman and Breanne Best, Department of Agriculture and Food, Western Australia.. Soil penetration resistance was measured with a Rimik CP40 cone penetrometer when the soil was at field capacity in both trials... The soil pH deeper in the soil profile was not measured at the time but is assumed to increase to around 5, which is typical for the soil type...
Grain yields of both crops at Merredin were very poor... In 2012, rotation trials of three years duration were initiated at Cunderdin (wheat - lupin) and at Merredin (wheat - chickpea) to examine the effect of crop row spacing, herbicides and applied nitrogen (in wheat only) on crops and weeds... In the chickpea crop, Outlook controlled annual ryegrass plants measured at 4 weeks after emergence, more effectively than simazine (Outlook 2 plants/m2 versus simazine 8 plants/m2 of annual ryegrass)...
GRDC Taxonomy:
Overview of talk Challenges with breeding for frost tolerance Update on current research Not going to be talking about variety recommendations agronomic options for managing frost.. Create population with genetic variation Conventional cross, mutagenesis, GM Select the best offspring from that for the traits of interest (Frost) Test that material in a range of environments for yield Commercialise it as a variety.. Select the best offspring from that for the traits of interest (Frost) 3...

Mention of a trade name or company in this publication does not imply endorsement of any product or company by the Department of Agriculture... I was educated by a group of farmers at Varley in 1982, to the importance of Crop Updates is a partnership between the Department of Agriculture, Western Australia and the Grains Research & Development Corporation 22.. Advisers and consultants should highlight the management options available to their clients, do sensitivity analyses which in effect, tell the client 'what happens to production, quality and profitability, if he chooses a certain man...
" Spiroxamine offers an additional cost effective mode of action against fungicide resistant powdery mildew.. Three fungicide modes of action (DMI, QoI, Amine) are represented in products such as Prosaro, Amistar Xtra, Tilt Xtra and Prosper that controlled fungicide resistant powdery mildew and gave economic returns in trials at Gibson in 2009 and 2012... Our aim is; using grain yield and quality results, current price estimates and delivery grade specifications, to compare the performance and gross returns from the use of a range of foliar fungicides available in Western Australia that h...
