The comparisons represent the general farming system and evolution in management over the last 30 years of many progressive grain growing farms in low-rainfall regions of Australia... The largest increase to yield and water-use efficiency was achieved by improved summer weed management (Scenario 3)... A wheat variety with a long coleoptile gives a large yield increase in combination with the other management improvements (Scenario 6)...

Tighter fallow management gives wheat best chance.. Photo of two men inspecting wheat.. While June was wet, with 100mm of rain recorded, July and August turned dry, and Graham says the crop appeared to "turn blue", or die, because of a lack of moisture...

Risk can be reduced by setting profitable crop yield targets, calculating the amount of water needed to achieve these yield targets and assessing that against available stored soil moisture and the probability of receiving additional moisture through in-crop rainfall... Research conducted by Dr Whish and funded by CSIRO and the Grains Research and Development Corporation (GRDC), reinforces the benefits of setting profitable crop yield targets, calculating the amount of water needed to achieve these yield targets and assessing that against available stored soil moisture and the potential for in-crop rainfall... The total water requirement is 260mm...

By strategically knocking down weeds in fallow paddocks at seeding time and keeping these clean from weeds until the next sowing, vital soil moisture is conserved for the subsequent crop... The next crop should be healthier, cleaner of weeds and produce a better two-year gross margin compared with two low-yielding cereal crops... Campbell Jones is among a new wave of growers in WA's eastern wheatbelt who are starting to use a spray fallow to reduce the risks associated with seasonal variability, herbicide-resistant weeds and growing non-profitable crops in low-rainfall years...

The use of Group A herbicides in fallow to control grass weeds such as the Chloris species - feathertop Rhodes grass (Chloris virgata) and windmill grass (Chloris truncata) - have shown to be a viable option for controlling young weeds... Recent research has investigated the use of some of these herbicides for fallow applications to control grass weeds, in particular the Chloris species - feathertop Rhodes grass (Chloris virgata) and windmill grass (C. truncata)... Trial results have shown that a minimum period of 5 to 7 days should occur between applications...

Growers that have the weed seed bank under control will save herbicide costs; have greater rotational flexibility; have greater options to use diverse tactics that would otherwise be cost prohibitive; and by reducing the frequency of herbicide applications, will delay the onset of herbicide resistance... With any discussion on managing resistance we need to start with the basics and understand why we have the problem in the first place... Registration of high application rates by this technique may allow the control of resistant weeds that have survived a preceding application of a different mode of action...
