Scoring system for assessing char siew bao quality.. Effects of water addition, sugar, and sponge mixing time on char siew bao quality attributes, expressed as regression equation coefficients Regression equation coefficient from corresponding fitted model.. Response surface plots for textural quality attributes as a function of water addition (% Farinograph water absorption, FWA), sugar (% flour weigh), and sponge mixing time (% Farinograph dough development time, FDDT)..

A disease control model for crown rot in Victoria and South Australia (SA) which provides crop management recommendations to reduce the build-up of Fusarium inoculum and avoid sowing into high disease risk situations... Crown rot is highly spatially variable, so intensive and extensive sampling programs were undertaken to assess the the reliability of results produced using current sampling protocols... Intensive stubble and soil sampling was used to assess the scale of spatial variability of crown rot and whether taking soil cores in a row crop was causing "spikes" in results...

Current farming systems expose farmers to heavy losses during good seasons when the risk of crop failure is low and returns could be maximised by additional levels of N... The SOI phases, originally developed in Queensland, can be used to identify a set of past years of similar climatic characteristics (analogue years) to the present season... Seasonal climate forecasting is a crucial tool for growers to micro-adjust and governments to macro-adjust economic strategies and policies to reduce impacts on private, estate and national economic objectives...

A reliable, accurate and sensitive RT-PCR test for detecting Wheat streak mosaic virus (WSMV) in bulk samples of wheat seed was successfully developed, validated in blind studies and made available to the agricultural industry through AGWEST Plant laboratories for use in testing seed stocks... The three main ways to combat WSMV are to 1) destroy the green bridge before sowing to prevent transmission of the virus by the WCM, 2) use wheat seed stocks that have either none or only low levels of the virus, and 3) to sow crops late when temperature conditions are non-conducive for WCM...

Blade, Kite, EGA Eagle Rock, and Sloop SA barley showed tolerance to metribuzin, exhibiting little change in seedling density and anthesis dry matter (DM) when treated with metribuzin (187.5 and 375 g/ha)... Estimates of regression parameter B (slope s.e.) for seedling density (plants/m2) and shoot DM (g/m2) of wheat genotypes treated with metribuzin (0, 187.5, and 375 g/ha) at a eld site at Cleve in 2004 Two-tailed t-tests were performed to compare differences in B (slope) values with Spear, a sensitive genotype... There is a need to identify alternative sources of metribuzin tolerance, w...

WAHRI is widely recognised among growers and their advisers as a centre of research excellence in the field of herbicide resistance and weed management... The global reputation has resulted in more than a dozen overseas researchers being attracted to work at WAHRI, contributing to the research output at minimal cost to the Australian grains industry... Timely surveys have replicated previous surveys by WAHRI and quantified important changes in levels of herbicide resistance in Western Australia...
