yield increase

The Technical Resource Manual for Farm Fire Recovery was developed by the SA Research and Development Institute in response to the Lower Eyre Peninsula 'Black Tuesday' fire in January 2005... Information is provided on the key management issues that growers will need to address to return paddocks to full production... NSW Minister for Primary Industries, Land and Water Niall Blair said this year's finalists were all great examples of women making outstanding contributions to their regional communities: "I congratulate Fiona Mead, Aimee Snowden and Hannah Wandel, who were selected from an exceptional field of nominees and are all leaders and role models for regional NSW."..

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...

Higher yields require increased monitoring and correct management practices to avoid yield penalties... nitrogen supply at sowing should be 100-120kg n/ha, including the amount already in the soil and amount to be applied... Trial results have shown a narrower row spacing, such as 17.5 centimetres (above), can give higher yields in irrigated wheat than wider row spacings...

Trials were conducted to develop agronomic techniques and new varieties to increase grain yield in the high rainfall zone of the South East (SE) of South Australia (SA) and on Kangaroo Island (KI)... The project was designed to develop improved agronomic treatments and varieties for the high rainfall zone in the South East and Kangaroo Island to increase the area of crop and overall crop yield by 10%... The survey undertaken for this project showed large variation in the crops grown in different regions...

The project has shown how the practice of SSM can deliver large, consistent and recurring increases in the yields of cereals, canola and pulse crops grown on Sodosol soils across the HRZ of Victoria... The practice was developed to overcome crop yield constraints caused by dense clay subsoils that are widespread across the HRZ. Low aeration in the clay limits deep root growth into the subsoil and this has been identified as a cause for the generally disappointing crop yields in the Victorian HRZ. Earlier research demonstrated how SSM can transform the physical properties of the clay layers... For sites with the 1/2 SSM treatment (6 site x seasons), the commercial wheat crop yielded an average of 6.2t/ha, the full SSM 9.7t/ha, and the 1/2 SSM 8.8 t/ha (42% response).This was surprising and suggests that this lower rate of manure incorporation will also give increases in grain yield...

Canadian researcher Dr Malcolm Morrison gave an insight into the 'home of canola' at the GRDC Grains Research Update in Adelaide in February.. A short growing window is no barrier to canola growers on the Canadian prairies, where the crop is gaining ground on wheat... Dr Morrison said the message being given to Canadian growers is to embrace variable-rate technology to optimise inputs, target a seeding rate of about 150 seeds per square metre (to achieve a plant population of 80 plants/m 2 ), and aim for slower, shallower seed placement to improve emergence...

The gap between growers' current wheat yields and what they could be achieving has been illustrated for the first time via a new interactive online tool... The gap varies between regions and seasons, but on average over the past 15 years the gap has been: 1.4 t/ha in the western cropping region 1.7 t/ha in the southern cropping region (Victoria, South Australia, Tasmania and southern and central New South Wales) 1.9 t/ha in the northern cropping region (Queensland and northern NSW)... Region National, North, South, West < Keep browsing 0 Responses to Wheat yield gap maps show where gains can be made..

In contrast to the uncertainty, Precision Agriculture has definitely come of age in Europe, where farmers are relying on PA tools and techniques for improving returns from their land... As the range of techniques expands, there is a need for agronomists to use their detailed local knowledge of paddocks and crops to select just which technique offers the best chance of a fast return on investment... While intensive soil sampling is still economic in Europe there is a recognised need for a real-time sensor to map soil fertility and Veris ( www.veristech.com ) was the first to market last year with a pH mapping system capable of taking and analysing between five and 10 pH samples per acre without stopping...

Growers Luke (left) and Greg Moroney have trialled incorporation of organic matter on their property at Brimpton Lake on the Eyre Peninsula, SA... "David Davenport and Primary Industries and Regions SA (PIRSA) have been doing trials on part of our property looking at methods of improving sandy soils and the results from organic matter incorporation were so good we decided to give it a go," Luke says... "The trials were using a high rate of 10t/ha of lucerne hay, which was giving great results but would be very expensive on a farm-scale, so we have tested a reduced rate of 5t/ha clover hay spaded to 300mm depth."..
