Oestrogenic Subterranean Clover Guide. Identification And Remediation, Kevin J. Foster, Megan H. Ryan, Daniel R. Kidd

Bulletins 4000 -

Subterranean clover (subclover, Trifolium subterraneum L.) is an annual pasture legume that provides high quality feed for livestock. It is estimated to be sown over 30 million hectares across southern Australia, with cultivars developed for the low, medium and high rainfall zones. Unfortunately, some older cultivars contain high levels of phytoestrogen which can affect the reproductive system of sheep and cause other health issues. This became a significant issue for sheep producers from the 1940s as new land was cleared and sheep grazed subclover-dominant pastures. There was a collection of livestock issues observed and these were grouped together under the …

Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr, Meredith M. Guthrie

Bulletins 4000 -

The Bulletin is a comprehensive guide for pastoralists, agronomists, agribusiness and the broader community on the growing of irrigated crops and pastures within a rangeland pastoral setting.

Dispersed irrigation developments on stations throughout the northern rangelands (sometimes referred to as mosaic agriculture) has created opportunities for the introduction of more productive forage species and pastoralists can now grow high quality forage for 12 months of the year. This can help to overcome the key constraint of traditional pastoral systems, the low quality of the feed over the dry season that typically results in stock losing condition.

Plant Diseases Impacting Oaten Hay Production In Australia - A Review, Kylie Chambers, Geoff J. Thomas

Bulletins 4000 -

In Australia, there are a range of fungal, bacterial and viral pathogens that infect oats, impacting on yield and quality of grain and hay crops. The overall impact of these diseases on oaten hay production is not well researched or understood, especially compared to that of other cereal crops. Export hay is evaluated on physical qualities such as stem thickness and greenness and nutritional qualities including water-soluble carbohydrates, neutral detergent fibre, acid detergent fibre and dry matter digestibility. The colour/ greenness of oaten hay can be reduced by disease lesions, chlorosis and saphrophytic fungi growing on dead tissue all of …

Canola Agronomy Research In Western Australia, Department Of Primary Industries And Regional Development, Western Australia, Jackie Bucat, Andrew Blake

Bulletins 4000 -

The Tactical Break Crop Agronomy Project and the Achieving Stable and High Canola Yield Across the Rainfall Zones of WA Project were initiatives originating from a Western Panel Spring Tour of the low rainfall zone. The panel was focussed on investing in research and development to support the expansion of canola into low-medium rainfall zones where it could be incorporated into short-phase cropping systems. The importance of managing nitrogen application in soil with declining organic matter as farms moved from a long pasture phase system was paramount. Furthermore, understanding the management changes required to transition from OP to hybrid canola …

Growing Biserrula To Improve Grain And Livestock Production, Angelo Loi, Natalie Hogg, Clinton Revell, Diana Fedorenko

Bulletins 4000 -

Biserrula pelecinus is a new genus of pasture legume which was developed for commercial agriculture by a team of Perth-based legume pasture scientists in the early 1990s. Biserrula is an annual pasture legume that is found in natural grasslands of the Mediterranean Basin, frequently on acidic soils derived from granite. It was this feature that first caught the eye of researchers who were attempting to develop species that could tolerate the soil stresses of acidity and low moisture-holding capacity. These stresses are common in WA and when they occur together they are problematical for the survival of annual medics and …

Western Australian Rangeland Monitoring System For Grasslands: Field Manual, Andrew Craig, Philip Thomas
