We have now successfully applied this method to wheat, and have been successful in generating many new semi-dwarfing alleles in the same gene as the original Rht1... The studies now provide us with new sources of height variation in both barley and wheat, Australia?s two main cereal crops... A new method has been developed that allows the isolation of large numbers of mutants involving a gene that is important in regulating growth of wheat and barley...

An independent economic analysis of the GRDC's investment in no-till farming research has found that the corporation's $4 million investment has returned $141 million in benefits to the grains industry - a benefit/cost ratio of 36 to one... The no-till projects raised awareness of no-till opportunities and benefits and provided greater confidence to those willing to undertake change.".. Quantified benefits of the GRDC's investment included short-term gains from improved soil moisture retention and longer-term benefits such as improved weed and pest control and reduced soil erosion...

The system Prolonged periods of low rainfall over the past ten years in southern NSW have prompted many growers to become more proactive and adapt to the changing conditions by modifying their farming systems... No-till, stubble retained farming systems are rapidly being adopted to maximise crop water use... Despite the many benefits of this system, the efficacy of pre-emergent herbicides remains one of the major concerns for growers who have adopted this system, and remains a barrier.....

When Philp Brodie Grains faced potential traffic disruptions from a new neighbour - a Bunnings hardware store - the company reluctantly decided it would have to move... As well as its grain merchant and seed specialist business, Philp Brodie housed a grading and milling operation, Maralong Milling, owned by Philp Brodie directors John Philp and Peter Brodie and local milling stalwarts Ron Plant and Geoff Arthy... As a small producer of soybeans (and mungbeans), Australia's crop is a niche production, which is why the directors say keeping soybeans GM-free is important to their business...

A match made in canola heaven.. In the first series we look at how growers and researchers teamed up to turn canola into one of the mainstays of today's cropping system... "Over a decade of experiments, our team demonstrated the rotational benefit of canola, and growers saw that while it could be expensive and tricky to grow, it was profitable if you took a two-year view," he says...

This project aims to continue to develop Variety Specific Agronomy Packages (VSAP) for wheat, canola and lupins in southern NSW and wheat and chickpeas in northern NSW... The emphasis is on these crops as the development of management packages for barley and other pulses are currently covered under separate GRDC funded projects, DAN00028, Eastern Barley Agronomy and DAN 463, Pulse Agronomy... The focus will be on issues that improve the potential of a variety in a farming system rather than issues that improve farming systems as a whole...

No-till captures carbon for Kyoto.. After spending billions of dollars exploring high-tech engineering options to sequester carbon - like pumping carbon dioxide (CO 2 ) into underground geological structures or deep into the ocean - researchers in the US have acknowledged that farming and forestry are the most cost-effective means of removing CO 2 from the atmosphere... When Dr Rainbow visited the US, the voluntary carbon market was offering less than US$2 (A$2.60) a tonne of CO 2 while in Europe the figure was 19 euros ( 2 concentrations is valued at more than US$25/t and carbon credits are trading on Chicago Climate Exchange for just under US$5 and..

Clay and spading helps rebuild non-wetting soils.. On 19 July 2010, after about 78mm of rain, the nil treatment (Figure 1) had a lower plant density and went on to yield 0.66t/ha, while the 260t/ha of clay incorporated by spading plot (Figure 2) had a high plant density and went on to yield 1.41t/ha... In 2010 Trevor had electromagnetic surveys (EM38), gamma-ray spectrometry (radiometrics) and deep soil analysis done for measuring and mapping the depth to clay and he used these maps in 2011 to strictly apply clay only where it was needed...

He estimates 90 per cent of the 2400 hectares he uses for cropping on his farm does not wet-up on the surface (0 to 10-centimetre layer) during the growing season unless there is a major rain event... Benefits of claying "On the treated areas, we have probably doubled our crop yields in favourable seasons - although seasonal variation makes it hard to gauge what the actual gains have been," Clint says... Clint says a major benefit of claying is that weeds germinate in a tighter period in the first year, allowing an effective first knockdown herbicide application...

western region when to sow wheat to minimise risk the optimal sowing date results in wheat flowering after the last frost and with adequate reserves of soil moisture before heat stress begins... only in seasons with a favourable spring did yields increase with later sowing... in Australia, developmental stages are commonly referred to as 'growth stages'...
