pasture phase

Catalogue: GRDC Final Reports
The project was designed to provide information about the ability of biserrula ( Biserrula pelecinus) pastures to contribute to grain production systems in the medium and low rainfall wheatbelt areas of Western Australia... Pasture crop rotation trials demonstrated that biserrula and its rhizobia are capable of persistence through at least three consecutive cereal crops, allowing farmers to crop more frequently and still retain legume dominant pastures... Further work is required to identify what appears to be a secondary plant compound in biserrula that can induce photosensitisation in some environmental circumstances...

In the short term (at least the next 8 years), these crops will in essence provide new uses for old herbicides and old herbicide groups... In summary, the research also indicates that the public is least likely to approve of GMOs that: Benefit a company over the public; Involve gene transfer from species that are not closely related; Are not undertaken for a societal benefit; Are perceived as being possibly harmful to people or the environment; or Is a food over a non-food application... At the outset of the project, a draft strategy was proposed, and it was this strategy that the project team and participant growers/consultants worked towards implementing and evaluating...

The adoption of no-till in WA is widespread with approximately 86% of growers using no-till for a proportion of their cropping (D' Emden and Llewellyn, 2004)... No-till crop production systems have major benefits for growers in Australia, such as timeliness of operations, moisture harvesting, erosion control and higher yields... Research in Western Australia shows oat cover crops can drive down the weed population but not as effectively as a pasture phase of sown or volunteer barley...

Hosted by GRDC Grains Research Update for Growers sponsored by.. Barley yellow dwarf virus can be a threat in all environments, and it is recommended that seed be treated with imidicloprid, or crops closely monitored for aphid infestation and sprayed ... Pea growers have generally been advised to sow pea crops 2-3 weeks after opening rains so newly emerging crops can avoid these spores...

Agronomy: the key to productive pastures that can sustain profitable grain production in Queensland.. The benefits from pastures are directly related to their productivity; poor pastures will limit beef production, and will do little to improve the soil and future crop production.. The paper provides a series of insights into the need to consider pasture phases in much of our cropping lands, the contributions these pastures can make; and the need for better agronomy to maximise these contributions and make them last...

"After the treatment, we had a good stand of oats, clover and annual ryegrass and were able to use this for two intensive grazing periods in June and July," he says... Bryan says a combination of improved pasture paddocks prepared earlier in the year, deferred grazing on long-term grazing paddocks and some crop grazing is ideal to set up paddocks for his lambing period... "The additional annual ryegrass and weeds stimulated by cultivation can then be controlled by a 'hay freezing' technique - using glyphosate or paraquat - after the clover has set seed in later spring," he says...

LEY PASTURES - THEIR FIT IN CROPPING SYSTEMS.. The pastures need to be removed earlier (e.g. June) to allow sufficient fallow length to reduce any yield penalty in subsequent crops (Fig. 4)... Growth and livestock prices fluctuate from year to year we also explore how sensitive returns are to these changes (Table 10)...

The use of economic thresholds of weed numbers based on their yield impact in the current crop alone is irrelevant!.. 10 use high crop sowing rates (6) crop-top lupins with paraquat (1) use seed-catching cart, burn dumps (10) a The number of years in which this treatment was applied is shown in parentheses... The tactics were able to compensate for the failure of post-emergent herbicides in years when they failed due to adverse seasonal conditions To explore the benefits of IWM further, the WeedRisk model was tested for a range of rotational and IWM options over a 20-year period for three key cropping weeds: wild oats, wild radish and annual ryegrass (Table E7, below)...

In summary, 20 trials have now recently been undertaken across a number of seasons and locations in NSW. None of them have demonstrated S responses in yield or oil %. This does not exclude deficiency and yield penalties from occurring but does highlight that the frequency and the likelihood is not high... Delaying any action that has the potential to cease grain fill will see more seeds achieve their maximum size and improve yield... In summary there was no 'concerning' level of seed loss observed at any trial or timing, correlating well with the yield data...
