(QDPI & F) Graeme Schwenke Nutrient demands in high yield crops (NSW DPI) 12:42 PM Lunch 1:42 PM Concurrent session 1 (see next page for timetable) 3:12 PM Afternoon tea 3:42 PM Yield and quality losses due to crown rot in Steve barley and wheat... Overall, the higher P rate also led to increased dry matter at the plant cut stage (mid-late tillering) and at the 3 times of NDVI measurement... Overall, mustard and juncea canola have many advantages over canola, and would be better suited than canola to the drier western parts of northern NSW...

The rotational benefits of canola were usually restricted to just the first subsequent wheat crop, whereas additional wheat yields can occur for 2 years after a legume... Gross margins achieved on-farm for wheat in 2011 may have been lower than shown in Table 2... The gross margin calculations depicted in Figure 5 assumed that canola yielded 50 % of wheat at that site in that year...

Using winter cereal/summer crop and winter pulse/summer crop rotations are key strategies for reducing crown rot pressure and the incidence of root lesion nematodes (RLN) in the northern region... Summary of a decade of experimental results from the northern grains belt showing the rotational benefits of chickpeas on yield and grain protein levels of the following wheat crop + fertiliser N (75-150kg N/ha).. Results from six sites in northern NSW showed that chickpeas provided an average soil nitrate benefit equivalent to 42kg nitrate-N/ha and an average grain yield benefit equivalent to 1.0t/ha for the following wheat crop (figures 1 and 2)...

Sow the following wheat crop directly over the row of the previous years break crop and NOT between the old rows.. 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)...

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)...

Gary Lang burns wheat stubble before sowing canola to reduce the risk of frost damage on his property north of Wickepin, Western Australia... Since then, Gary has burnt his wheat stubbles immediately before sowing canola... Gary says a hot burn is done one or two days before canola is sown and there is not usually enough stubble in the following wheat crop to warrant burning...
