Leader of the Southern Pulse Agronomy project Dr Jason Brand says growers need to get the fundamentals for their faba beans right up front, such as row spacing, plant density and pest and disease management, to avoid any issues in the canopy later in the season... Growers wanting to avoid issues with canopy management in faba bean crops later this season should first get fundamental measures such as row spacing, plant density, inoculation and pest and disease management right earlier in the season... Dr Brand has been looking at novel ways of reducing the problem in the HRZ, including chemical and mechanical treatments, but says the key message for growers was still to focus on getting the important things right early in the growing season...

" Goondiwindi GRDC Grains Research Update Day 1 - Tuesday 4 th March Time Topic Speaker (s) 10:00 AM James Clark (Chair Northern Welcome Panel GRDC) 10:10 AM General plenary (Supported by North West Local Land Services) 10:10 AM 10:40 AM.. Overall, both models are acceptable for modelling soil evaporation over a range of soils and seasons provided accurate soil physical properties and starting water states are known... Overall, populations increased five times compared to before planting the summer crops, but remained below 250/kg soil (Figure 4)...

Influence of fungicide rate (mean of fungicide products - four site mean) Stem rust control assessed over the four trial sites revealed that using high rates was essential for the control of the disease, even if the fungicide had been applied prophylactically (before infection was visible in the crop)... Influence of cultivar resistance and fungicide application (Prosaro ) on yield and stem rust severity measured on the flag sheath 18 days after fungicide application at early dough (GS82) and assessed at mid dough - physiological maturity (GS85-90) - Bairnsdale, Gippsland, Victoria, 2010... The yield potential for the crop with no nitrogen applied is estimated at GS30 from the results of numerous of trials conducted in that region where NDVI at GS30 is divided by the number of growing degree days (GDD) greater than 0 C since planting, referred to as the INSEY units (in season estimate of yield)...

Best Practice Guidelines Cotton Farming Systems.. Growers may achieve maximum profitability by applying additional spring-irrigations... The nitrogen requirement of an 8 t/ha wheat crop is approximately 275 kg N/ha studies in 2008 showed that many long-fallow paddocks that lodged had well in excess of this amount of nitrogen available (see Figure 9 (a))...

Increasing Yield of Irrigated Wheat in Queensland and Northern NSW.. We present preliminary results from the GRDC funded 'Achievable Yields' project on the yield potential of irrigated wheat across the region... Results of sampling 12 irrigated wheat paddocks across southern QLD in 2008 (a) mineral N in the top 1.8 m of soil at sowing (b) grain yield reported by farmers, and yield loss calculated from the difference between potential yield (estimated from APSIM or non-lodged quadrats) and quadrat cuts of lodged crops...

Irrigated wheat appears to have a similar optimum planting rate to dryland: around 40kg/ha (100 plants/m2), possibly lower if the seed is going to be concentrated on top of a bed with large furrow gaps between beds. Planting higher rates than this will increase lodging susceptibility and could cause yield loss if it induces greater rates of lodging... Further work will be needed to experiment with different timings of N application to see how sensitive the strategy is to the date of N application, and if any slow release fertiliser products would be of benefit... Yield and water use benchmarks Preliminary analysis has been undertaken to determine the maximum yields that can be achieved from irrigated wheat in the northern region, and how much water is required by the crop in order to achieve these yields...

The Achievable Yields project is aiming to set yield and water use benchmarks for irrigated wheat in the northern region, while also helping growers address the main agronomic challenges that prevent them from maximising grain yield... Reducing sowing rate for lodging control: 2009 trials In 2008, very high seeding rates of 200+ seeds/m2 were used in many locations for irrigated wheat (or approximately 80kg/ha of seed or higher)... Yield and water use benchmarks Preliminary analysis has been undertaken to determine the maximum yields that can be achieved from irrigated wheat in the northern region, and how much water is required by the crop in order to achieve these yields...

Irrigated cropping regions of northern Australia are beginning to include cereal crops in their rotations more regularly given recent fluctuations in grain prices... Irrigators need to know the likely yields and water use requirement of cereal crops so they can compare the profitability of different crops, and also require better agronomic recommendations as to how best to produce cereals in irrigated paddocks... Varieties respond differently to some of the agronomic strategies being tested, so growers are advised to trial new varieties and agronomy on a small scale to ensure they are suited to the local growing conditions and farm management...

Please note that the research described in this paper has been carried out in New Zealand and that the use of agrochemicals in this applied research does not constitute a recommendation... Yield trends in wheat in New Zealand reveal large increases in productivity over the last twenty years... The Sirius wheat model developed by Plant & Food Research illustrates that there may be potential to capture more yield by moving sowing dates even further forward in New Zealand, although the model has not been validated for sowing earlier than April...
