Over the past thirty years, price relativities and technological development have motivated an increase in the area of land allocated to cropping, as opposed to pasture production, throughout the central wheat belt of Western Australia. Nevertheless, reducing the proportion of pasture in these rotations has challenged the future productivity of farming systems in this area. First, the frequent application of selective herbicides for weed control in extended cropping rotations has promoted the development of herbicide resistance in a number of major agricultural weeds. Second, the primary use o

The main hypothesis tested in this thesis was that poor animal production from saltbush pastures is due to the negative effects of high sodium chloride (NaCl) and potassium chloride (KCl) on the ruminal environment, and subsequent effects on microbial populations and products of rumen fermentation. This main hypothesis was tested in two experiments. In the first experiment (Chapter Four) the effects of saltbush and a formulated high-salt diet on the ruminal environment and microbial populations were measured over 24-hours following feeding. Feeding both the saltbush and high-salt diet increase

Lameness is one of the most important welfare issues in the dairy industry with all cows being at risk during their productive life. It decreases milk production, compromises fertility and increases the chance of being culled. To reduce the likelihood of lameness in cows, a thorough knowledge of the risk factors is essential. Risk factors have been found to differ between farming systems which highlighted the need for a project to identify risk factors of lameness in NSW pasture-based dairies.

Single superphosphate is derived from chemically treating rock phosphate into relative proportions of monobasic, dibasic and tribasic calcium phosphate to produce a commonly used source of phosphorus fertiliser for pasture systems. The leaching of phosphorus on susceptible soil types contributes to eutrophication and environmental damage. By modifying the chemistry of single superphosphate to match a soils phosphorus binding index and rainfall conditions, pasture dry matter yield can be maintained and leaching of phosphorus significantly reduced.

In the Australian dairy industry, and in particular Victoria, there has been a shift away from seasonally concentrated calving patterns. Reasons for such a shift stem largely from improved feeding of cows with year round feed supplies, and the introduction of new germplasm from North American Holstein Friesian animals into some Australian dairy herds. Such impacts have resulted in an increase in the phenotypic and genetic potential of cows to produce more milk and be milked for longer than the standard 305 days under seasonal calving systems. The increase in high output cows has come at an ass

Dewatering of groundwater systems has become a common practice for iron ore mining in the Pilbara region of Western Australia. While the discharge of surplus water to local tributaries and re-injection into the aquifer are widely practiced, the re-use of this water for irrigated forages is an innovative solution. However, the chemistry of the groundwater and the impacts on soil properties from long-term application of groundwater need to be assessed.

Despite the views of researchers about the advantages in WA conditions of the newly released annual pasture legumes over traditional pastures, there is a perception by some industry decision makers that their level of adoption has been lower than expected.

[Truncated abstract] In southern Australian farming systems the replacement of deep-rooted perennial native vegetation with shallow-rooted annual crops and pastures has resulted in rising groundwater tables and an increased incidence of dryland salinity. It has been suggested that to address this issue by restoring hydrological balance, large areas of agricultural land need to be vegetated with perennial plants. One of the most agriculturally productive ways to do this is to introduce perennial pastures, both into upslope groundwater

The use of annual-based pasture and/or annual crops is now common practice in the higher rainfall regions of southern Australia where livestock grazing is the traditional practice. The lower water use of these annual-based systems, compared with systems based on perennial pastures, exacerbates issues of waterlogging, rising watertables and salinity in these regions. For environmental reasons farming systems used in the higher rainfall regions should target the use of more perennials in the landscape, but this should not be done at the expense of farm productivity or profitability.

This thesis investigated strategies for mitigating detrimental effects of hot and dry summers (i.e. supraoptimal temperatures and soil water deficit stress) on home-grown feed production in south-eastern Australian dairying regions. Strategies included incorporating alternative species into the feed-base and modifying aspects of feed-base management. Field research was conducted in north-west Tasmania, where summer conditions are forecast to become hotter during the 21st century, challenging the existing perennial ryegrass (Lolium perenne L.) feed-base.

Aerobic rice is becoming a more promising rice cultivation system due to increasing water scarcity for irrigation and occurrence of drought, especially in Australia. Rice cultivation on aerobic soil under rainfed conditions has shown potential for successful rice cultivation in tropical climate. Strategic irrigation during the critical growth period can help reduce the water demand on farm. Central Queensland has an annual rainfall of ca. 800 mm, and about 600 mm occurs during the wet season from December to March; whereas parts of the wet tropical north Queensland receive ca. 3000 mm annual r

Sugarcane is a tropical plant grown for sugar production under a wide range of mainly warmer climates throughout the world whereas under temperate climates sugar beet is grown for sugar production. In Australia, sugarcane is grown predominantly in the tropical and subtropical regions of the east coast. Since 1996 there has been a rapid expansion of sugarcane production in the Mareeba-Dimbulah Irrigation Area (MDIA), which is part ofthe Atherton Tableland region, about 50 km inland from Cairns in north Queensland. The expansion has been due to declining sugar yields from sugarcane grown on the

<div>Australia currently produces 210 000 tonnes of onions annually. The major production areas are in southern Australia where the predominant onion type is adapted to an intermediate long daylength. Queensland's annual production is stable at 10% (20 000 to 25 000 tonnes) of the national production. Ninety percent of the Queensland crop is grown in southern Queensland (Lockyer Valley and the Darling Downs). Small production areas can be found in central and tropical north Queensland. Consequently, onions in Queensland are grown under a predominantly subtropical environment. Crops are sown fr

Pachymetra chaunorhiza is an important soilborne pathogen of sugarcane and is found only in Australia. Pachymetra root rot is managed primarily by growing resistant cultivars, which are chosen for planting based on oospore levels in the soil. This management strategy does not account for differences in virulence among Pachymetra populations, despite previous research demonstrating that two genetically distinct groups of Pachymetra occur, which may differ in pathogenicity. Higher than expected yield losses have been associated with high oospore levels under some cultivars with intermediate resi

Recent years have seen the emergence of the concept of “functional foods”– where the value of food products is based on their health-benefiting properties in addition to their basic nutritional value. Globally, the functional food market is worth US $170 billion and is projected to grow at 7.5% p.a. over the next 10 years. In order to capitalise on this lucrative emerging market, producers and wholesalers need to demonstrate that their products contain high levels of these desirable compounds. This is typically assessed through time-consuming, expensive analytical techniques such as high-perfo
