Varietal differences in yield loss with delayed harvest can be in excess of 1.5 t/ha... There was a large difference between the amount of height reduction measured at the two sites with the maximum height reduction being 7 cm at Spring Ridge in 2011 compared to 34 cm at Moree in 2012... The low protein of Commander has generally been an advantage to meet malt specifications over the past couple of seasons extremely low proteins have been achieved throughout the region (<9%) suggesting that yield may have been sacrificed at this level...

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...

Strategy: Avoid using Picloram in sorghum crops if double cropping back into chickpeas... In the short term, the decision on row spacing and planter configuration will in most cases be largely determined by the: planting equipment and machinery available at the time current paddock and farm layout tillage practices... Growers must seriously consider planting time, and weigh up the potential yield benefits of early planting against the risk of frost and cold temperatures at flowering...

There was a large difference between the extent of height reduction measured at the two sites with the maximum height reduction being 7 cm at Spring Ridge in 2011 compared to 34 cm at Moree in 2012... Gairdner has been found in previous studies to achieve approximately 1-1.5% higher protein than Commander with the same N input, which was again the case at Moree and Bithramere in 2011... For the purposes of this paper yield and anthesis dates for 9 and 11 varieties for the wheat and barley TOS trials, respectively, are presented...

Sowing method (knife points or discs) did not affect performance of pre-seeding herbicides... Project No.: DAW 0134 Paper reviewed by: John Holmes Crop Updates is a partnership between the Department of Agriculture and Food, Western Australia and the Grains Research & Development Corporation 241.. Overall, the correlation coefficient between the observed ED 99dosages and the dosages predicted using Model A was 0.60 with p < 0.06...

"Having high N levels in combination with good water supply early in the crop's life is a recipe for high lodging risk, although there are several other agronomic factors that increase lodging risk as well," he says... "Delayed N application seems to reduce lodging risk substantially, but only if the crop shows symptoms of moderate to heavy nitrogen stress at GS31," he says... We are still experimenting with the best rates, but it appears that N levels need to be at or lower than about 40 to 80 units of N (inherent soil N plus applied N) in the top 90 centimetres at sowing to really achieve the right level of N stress to substantially reduce lodging risk...

Since then, this destructive disease of cotton has continued to spread and is now in most cotton growing districts in and , with the exception Tandou... A total of 5 experiments were completed, including two preliminary experiments to initially trial techniques/methodologies, so there was a variation in spore concentrations used, crops tested, plant tissue plated out and age of plants assessed following inoculation (Table 2)... 6) Previous studies have shown that when other crops are incorporated into the soil in the presence of Fusarium, the disease severity increases...
