subsequent wheat crop

Improving water use efficiency using cover crops of millet... Soil water was measured at cover-crop planting, time of spray-out (2004 replicated sites and all 2005 sites) and at all sites at winter crop planting... In the analysis an average world oil price of US$68.40 a barrel (West Texas Intermediate) and an exchange rate of US74 cents is assumed...

Canola tops break-crop gains.. Canola plantings have continued to increase in Western Australia and local researchers are working collaboratively to fine-tune tactics to help optimise profits from canola and other break crops across the grain belt... CSIRO senior research scientist Dr Roger Lawes says modelling shows that adding a break crop such as canola to continuous cereal rotations can be worth an extra 0.5t/ha of wheat following the break phase...

Growing break crops in a well-managed way can significantly and consistently boost the yields and profits of subsequent wheat crops in good seasons and reduce overall farming risks... Dr Lawes said an analysis of 30 years of data from across the WA grainbelt using the crop and economic modelling systems APSIM and LUSO indicated there was a 0.6 tonne per hectare average yield benefit in wheat crops grown after a lupin break crop and 0.4t/ha benefit following canola, compared with wheat grown after wheat... "We found the first wheat crop in a continuous wheat sequence could increase costs and depress yields in the second and third year wheat crops and reduce the probability of these subsequent wheat crops making a profit," he said...

Until such varieties are released, northern growers and advisers need to select varieties firstly on the basis of crown rot risk and then manage for stripe rust ... There is a risk of WSMV being spread through infected seed into new areas... We have not been able to determine an economic threshold for RGB in sorghum from these trials...

Optimising water use efficiency in western NSW.. The relative merit of different rotation crops can also be assessed by looking at the amount of water they extract from the soil profile... Research has shown that canola is better able to extract phosphorus (P) from soil than wheat (Bolland and Brennan 2008) meaning that maximum yield of canola can be achieved with lower P application than is required for wheat...

Break crops could hold key to tap soil phosphorus reserves.. University of Adelaide research, funded by the GRDC, on break crops has demonstrated positive effects on phosphorus uptake and yield in subsequent wheat crops... Wheat following a break crop has a greater P uptake and higher yield than continuous wheat rotations...

Cover crops - Millet shows its worth as a cover crop millet.. Cover cropping with summer grasses such as millets reduces erosion, increases rainfall infiltration, maintains soil biology and improves subsequent winter crop yields.. Our test sites showed that cover crops of millet protected the land from erosion and seemed to aid water infiltration and retention, improving the establishment of subsequent winter crops...
