The best way of achieving that is through a double break and that is 36.23: a situation where you might have a pasture or a hay crop or a grain legume and then the 41.58: next year you have a canola so you have got two good years of control on grass weeds and 46.79: you have also suppressed root diseases like Take-All and you are really setup to be able 51.33: to grab an early sowing opportunity and go in and sow a slow maturing wheat without getting 56.479: a knockdown on any of the weeds... For 125.09: instance in southern NSW if you have got Wedgetail and Gregory, Wedgetail being a winter wheat, 130.74: Gregory a mid-fast spring wheat you can take advantage of a sowing opportunity over a three 136.75: month period by switching which variety you choose then you maximise the yield of both 142.2: by ensuring that as much of that crop is flowering during the optimal period...

Inter-row weed control in wide row lupin using knockdown-based tank mixes Dr Abul Hashem 1, Ray Fulwood 2and Chris Roberts 3, 1Senior Research Officer, Department of Agriculture and Food, Northam, 2Farmer, Meckering, WA, 3Technical Officer, Department of Agriculture and Food, Northam.. Weed dry matter was reduced (Figure 2) but due to the dry season, only marginal increases in lupin yields compared to the broadcast treatments were realised due to the likely competition for water... Enhancing the depletion of the existing seedbank is just as important as controlling seasonal seed set...

Sowing opportunities were assessed for each day in the sowing season based on PASW% of seedbed [0-100mm depth] or topsoil [0-200mm depth]... Seedling performance was assessed for each sowing opportunity by counting the days between germination (dry sown) or sowing (moist sown) and July 19 when seedlings were exposed to lethal or disabling topsoil [0-200mm] conditions ( Table 1 )... In 50% of years the first opportunity occurs before early May and 10 days of sowing will have been achieved by early June ( Table 3 )...

Seedling performance was assessed for each sowing opportunity by counting the days between germination (dry sown) or sowing (moist sown) and July 19 when seedlings were exposed to lethal or disabling topsoil [0-200mm] conditions (Table 1)... In 50% of years the first opportunity occurs before late April-early May and 10 days of sowing have been achieved by mid-late May. Exposure to disabling water deficits is more frequent and of longer duration than moist-wet seedbed sowings whilst exposure to lethal deficits is similar (sand) or slightly reduced (loamy duplex soil)... Exposure to water deficit 2 1 Dry sowing: start 10 April, water deficit assessed after germination day 2 Moist sowing: start 20 April, water deficit assessed after sowing day 3 Gd10, date of germination following 10 days of dry sowing..

" Delayed sowing of lupin, a risky strategy to control wild radish... We also describe simulation modelling to assess the likely delay in sowing after forgoing an initial sowing opportunity based on historical weather data... Wild radish biomass measured at crop maximum biomass increased as the density of wild radish plants increased in both May and June sowings...

The majority of current wheat varieties need to be sown in the first half of May in order to flower during the optimal period for yield in most environments, which unfortunately coincides with the period of recent rainfall decline... Growers wishing to maximise farm water-use efficiency need to adopt strategies that will allow them to get as much of their wheat crop as possible flowering during the optimal period in their environment... The article reports results from several experiments conducted across southern Australia and farmer experience investigating the potential for earlier sowing to increase wheat yields in the face of autumn rainfall decline...
