Under a cloudless March sky, Colin Hutchinson with shovel in hand, was making the year"s big decision - when to sow the first crop... Photo: Too early for rain, but there"s enough moisture in Colin Hutchinson"s soil to start sowing early... "I actually need more silos to hold a greater range of seed, so I can take advantage of early rain with faba beans or if it is a later season I can sow chick peas, or later still I can opt for grain sorghum, sunflowers or maize as a summer crop...

High moisture grain generates heat when put into a sealed silo, providing ideal conditions for mould and insect growth... The key is to act quickly and effectively to manage the moisture at harvest, and a new fact sheet on Dealing with high-moisture grain has been released by the Grains Research and Development Corporation...

With wet weather hampering what is left of the Western Australian harvest, growers are advised to act promptly to deal with high-moisture grain... Detailed advice to help growers manage grain which is over the standard safe storage moisture content of 12.5 per cent is outlined in the Grains Research and Development Corporation (GRDC) Grain Storage Fact Sheet - Dealing with high-moisture grain... Continuous flow drying - grain is transferred through a dryer, which uses a high volume of heated air to pass through the continual flow of grain;..

One innovative central NSW grower finds building his own machinery has two benefits - it saves money and he ends up with exactly the machine he wants.. Overall, he says the disc seeder was the way to go: "We can sow on lower moisture and I also never feel we are wasting moisture because as soon as you put a tine into this country, it opens right up for moisture to disappear.".. Location: Ungarie, central NSW Rainfall: 338 millimetres Soil type: medium red loam with average pH of 5 Cropping area: 2000 hectares of owned and leased country Crops: wheat, barley, field peas, chickpeas and lupins Average yields: 2 t/ha wheat Tractor: Caterpillar 55, 260hp Sowing equipment: homemade air seeder Spraying equipment: self-propelled boomspray built on a second-hand cotton picker pbrlogo Varieties displaying this symbol beside them are protected under the Plant Breeders Rights Act 1994...

High moisture grain generates heat when put into a sealed silo, providing ideal conditions for mould and insect growth... The key is to act quickly and effectively to manage the moisture at harvest, and so the GRDC has released a new fact sheet on dealing with high-moisture grain... The fact sheet - 'Dealing with high-moisture grain' - outlines a range of measures that can be taken, including blending, aeration cooling, aeration drying, continuous flow drying and batch drying...

Herbicide control of fleabane is difficult because it has a natural tolerance to herbicide uptake and is often targeted over summer when plants are well established and spray conditions are not favourable... In southern New South Wales it emerges through winter and early spring, whereas recent studies have found that populations from South Australia emerge as late as August to November, provided moisture is not limiting (see Figure 1)... The impact of fleabane control on stored soil moisture was also assessed in April for a selection of treatments at Bute and Pinnaroo (Figure 3.)...

Frost pre-empted by research and experience.. In the absence of a 'silver bullet', three growers explain how they combine experience with research to frost-proof their businesses... Other frost management strategies include: thermal imaging, which has identified a 3 C to 4 C difference in minimum temperatures between some paddocks, guiding where frost-sensitive varieties are planted; planting frost-prone paddocks last to help avoid the high-risk frost period; using paddock records to monitor frost history; and planting according to frost-prone areas, such as concentrating pasture crops and hay varieties on sandy zones and around creeks...

There is only an extremely small risk of WSMV being spread through seed... Wider row spacings and higher plant populations will result in a more even and shorter flowering period and harvest, due to reduced tillering (Thomas et al 1980)... It is highly likely that plant population should be somewhere in the range 100 to 150 plants/m 2...

Many catchment management plans have been prepared... Land use change to reduce leakage This research shows that drainage from cropping systems can be greatly reduced by replacing long fallow or continuous wheat systems with wheat/sorghum opportunity cropping or continuous sorghum... It has been found that black pointed wheat grain actually germinates faster than normal grain and is predisposed to sprouting should further rainfall occur...
