yield gap

Catalogue: GRDC Media
Wheat yield increases of 1.19t/ha possible in the north.. Maps detailing actual and achievable yield data have been compiled by the CSIRO and will be made accessible through a Grains Research and Development Corporation (GRDC) funded project... Dr Hochman said the research found that the northern region's yields were 5.3% lower than relative yields in the southern region and 8.9% lower than in the western region, suggesting there is significant scope to boost yields in the north through better application of current technologies and best practice...

" 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)...

The longer season cultivar Westminster topped the NVT trial in the region with a yield exceeding 6t/ha shorter season barley cultivars Skipper and Compass (under malting evaluation), Commander (malt) and the feed cultivar Fathom have also performed well... Early sown (May 10) wheat trials at the Southern Farming Systems (SFS) site in Inverleigh, southern Victoria have shown a yield advantage to feed wheat over the highest yielding milling wheat of 0.8-1.3 t/ha (10-17%), with yields between 7-9 t/ha... Looking at the data from Table 4, the yield gap between feed ( Beaufort and Revenue ) and highest yielding milling wheat ( Bolac ) cultivars is high in absolute yields (0.8-1.3 t/ha) compared to previous data taken from NVT and SFS cultivar trials in the region...

The drive to close the yield gap across New South Wales and Queensland cropping areas is continuing to gain momentum following the collection of hundreds of crop performance datasets for the Grains Research and Development Corporation (GRDC) funded National Paddock Survey... The National Paddock Survey initiative aims to determine the difference between actual yield and potential yield (the yield gap) and equip growers with the tools and resources to maximise their grain production per millimetre of soil moisture... Projects like the National Paddock Survey will provide this type of information and can help growers manage individual paddocks according to production potential and likely constraints as well as benchmark performance against other growers in their regions...

The potential to close this yield gap relies on a number of factors including local soil and environmental constraints, growers' capacity to invest in inputs and their risk preferences... The project aims to quantify the yield gap for sorghum in the summer and wheat in the winter and determine the contribution and interaction of agronomic drivers of this gap for a given year and site with trials being conducted at key sites on the Liverpool Plains and Trangie in the central west... The trials are focused on determining the contribution that several key agronomic practices make towards final grain yield, such as sowing on time, row spacing, seeding rates, nutrition, and hybrid selection...

GRDC research to help boost northern cereal yields.. CSIRO data suggests that northern growers could produce an additional 1.19 tonnes/hectare in wheat yield using better adapted varieties and best practice management, potentially adding thousands of dollars to an operation's bottom line...

14 BWD00024: Maintaining profitable farming systems with retained stubble in Victoria and Tasmania .................................... The over-arching aim of the project is to improve yield and water-use-efficiency of irrigated wheat production across the Northern Region by developing improved agronomic practices to reduce the incidence of lodging and increase the yield potential of irrigated wheat... Overall, the project will deliver a comprehensive research, communication and extension program that will ensure more effective management of water repellent agricultural soils in WA whilst building capacity for future soils research and development in Western Australia...

GRDC Grains Research Update Coonabarabran, February 2014 most sites achieved those returns within 2 crop seasons after deep P application may at least partly reflect the string of wetter seasonal conditions in recent years, although the results from Jandowae, Capella and Gindie all included dry seasons in at least one of the crops followed... Overall, the performance of the barley grain only varieties showed they are capable of producing around 6 t/ha of dry matter and still yielding between 2.7 and 3.4 t/ha of grain... Overall, the most prevalent virus was BWYV and in some locations more than 90% of symptomatic plants were infected with BWYV (Table 1)...
