" Attachment to Project DAS00017 Reducing the impact of climate variability Frost Table 1: Agronomic practices to reduce frost risk ranked in order of importance Soil Heat Bank Ranking Description Ave temp at Manipulation canopy height 1... Reducing frost risk by increasing the clay content of sandy surfaced soils is the strongest finding in South Australia... Crops sown twice with half the seed sown in each run gives an even plant density and has been found to more slowly release the soil heat so that it can have an impact on air temperature at head height in early morning when frosts are most severe...

Spread of flowering dates of dry sown crops can be successfully achieved through varietal choice and adjusting sowing order of the wet sown crop according to the flowering prediction of the dry sown crop... The aim of this paper is to discuss possibility of using varietal differences in phenology mechanisms to achieve a desired spread of flowering dates after dry sowing... The data were used to estimate: 1) spread for flowering dates of varieties across germination dates, 2) the range of achievable variation through varieties for given sowing dates...

Trials were conducted at Breeza, Narrabri, Emerald, Brookstead, Kingsthorpe and Gatton, although only the trials that exhibited significant levels of lodging are reported in this paper... The results from the trials suggest that Durums do possess greater yield potential than bread wheats of similar (quick) maturity, but also have a higher lodging risk on average... *Soil N measured for 0-120cm depth at Breeza & Emerald, 0-180cm at Gatton, and 0-90cm at Narrabri Table 2...

Research shows benefits of dry sowing wheat early.. Crop modelling work shows that dry sowing wheat in April can maximise whole-farm yields in Western Australia and minimise the likelihood of late-season heat stress, without significantly affecting frost risk... "Using data from 54 seasons at seven sites across the WA grainbelt, the modelling work shows farm-level yield benefits of up to 35 per cent - or up to 0.5 to 1.2 tonnes per hectare - from dry seeding wheat before autumn rains, compared with wet sowing wheat after autumn rains," he said...
