A field day inspecting various break options at Minnipa in 2012... A major GRDC-funded project has assessed the profitability of many different break options in five different low rainfall sites across southern Australia over the last four years... Grassy weed control followed a similar trend, though it should be noted that while a one year vetch hay break appeared to give strong weed control (third point from the right), this effect was short lived, and did not persist into 2014...

" Interspecific hybrids in lupins - stabilisation and trait transfer to fixed lines for lupin crop improvement.. Narrow-leafed lupin (Lupinus angustifolius) originates from the Mediterranean region and has become the largest grain legume crop in Australia due to its adaptation to infertile sandy soils, reasonable tolerances to diseases and pests and its use as a break crop... Lupins are used mainly for animal feed markets but more recently interest has increased in its use in foods such as breads, noodles, sausages and other products...

This project 'A review of GRDC crop rotation, break crops and sequencing investments' fits within the Advancing Profitable Farming Systems theme... The projects aim is to thoroughly review the investment both past and current across all GRDC regions, into crop rotations, break crops and sequencing... A detailed report will be produced that provides recommendations for the investment planning into future crop rotation, breaks crops and sequencing projects...

Photo of man digging into soil.. "If legumes are grown under ideal conditions, and sufficiently inoculated, they can add 30 to 120 kilograms of nitrogen per hectare, per year, back into the soil for use by other crops," says Dr Nikki Seymour, senior soil microbiologist at the Queensland Department of Agriculture, Fisheries and Forestry (DAFF)... Crops with wider rows were accessing more of their nitrogen from the soil reserves, leaving less available for the following cereal crop...

The results presented will focus solely on the mustard-wheat and chickpea-wheat systems and the last three years of the sequence trial (2010-2011-2012)... What the experiment has shown is that simply alternating row placement in consecutive years will not result in yield gains but a yield loss and increased CR (BO system)... Even the traditional on row system (OO) had a better yield and CR outcome than the BO system because the break crop was sown directly over the old wheat stubble row excavating the residue out of the row (tyne with spear points) and providing a direct break to the CR fungus (see Table 2 and 3)...

A major GRDC-funded project has assessed the profitability of many different break options in five different low rainfall sites across southern Australia over the last four years... After a two-year break, wheat yields increased by 0.5-1.25t/ha, with a benefit of up to 0.4t/ha observed in the second year of wheat... Growers are really expanding their horizons, using a wider range of crops in their farming system which, as the trials show, is a really positive move not only for soil health and weed control but also profitability," Mr Moodie said...

Rotation combats costly nematode issue.. The move to a cane/peanut crop rotation has dramatically changed the nature of farming for Bundaberg district growers Neville and Jason Loeskow over the past 20 years... "Survey work undertaken by Dr Graham Stirling from Biological Crop Protection found that plant parasitic nematodes were a much larger issue in cane growing regions than previously thought with Pratylenchus zeae found in every paddock sampled in the central coastal region of Queensland," Mr Halpin said...
