Soil salinity is a significant abiotic factor that impedes sustainable crop production in key agricultural regions worldwide. Saline cultivation adversely affects soil quality, whereas the use of saline water for irrigation disrupts the physiological and biochemical processes of plants. Continuous irrigation with high salt concentrations leads to a gradual buildup of soil salinity, thus hindering optimal plant growth and development. Consequently, there is a growing emphasis on breeding salinity-tolerant cultivars of various crops. In this study, 71 tomato accessions sourced from 20 countries and provided by the US Department of Agriculture were evaluated under controlled greenhouse conditions and subjected to …

Lupin Root Diseases - Diagnosis And Management, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Root, hypocotyl and stem base diseases can be significant problems in lupin crops, reducing stand density, plant vigour and yield. Root disease is present in nearly all narrow leafed lupin (Lupinus angustifolius) paddocks but in the majority of paddocks has only a small impact on crop development. However, in paddocks where high levels of root rot occurs, plant establishment, seedling vigour and crop yield can be significantly affected.

When a root disease is present in a crop very little can be done to manage it in that cropping season. It is therefore vital that the cause is correctly identified to …

Time Of Lambing, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Choosing the best time of lambing, and matching paddock feed availability to ewe and weaner needs is important for both productivity and profitability. The ewes' natural breeding season will also affect reproductive rates. The ewe flock is the key flock on the farm, so it is important to set up a system that matches their needs with the feedbase. A ewe’s condition will vary over the season depending on the feed available and her needs. A ewe’s energy needs will double in late pregnancy and triple in lactation. Having enough feed to meet her changing needs is important for production …

Cattle Performance Grazing Canola And Cereal Crops, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

The Department of Primary Industries and Regional Development conducted research to investigate and demonstrate the performance of cattle grazing canola and cereal compared to animals left on pasture and investigate the value of spelling the pasture during the time the cattle are grazing crops.

Cattle grazing cereal crops had a higher liveweight gain compared to the cattle that remained on the pasture. However to see a significant benefit from grazing dual purpose crops, the grazing period may need to be longer than 4 weeks particularly when grazing canola.

The highest growth rates for cattle grazing the cereal crops were achieved …

Rabbit Control: Warren And Harbourage Destruction, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

If correctly and appropriately undertaken, the destruction of rabbit warrens, or modification of the habitat so it becomes less favourable to rabbits, can be an important and effective part of reducing the impacts of rabbits.

Destruction of warrens can improve the overall effectiveness of rabbit control programs, even though many rabbits live and shelter above-ground under bushes, and in scrub). If undertaken properly, the ripping of rabbit warrens can often provide a relatively permanent and long-term benefit. Similarly, removing or modifying other forms of rabbit-harbourage (for example, removing rock piles) can help, particularly in semi-urban areas or on smallholdings.

Biosecurity factsheets

This factsheet provides information on control options for rabbits in urban and semi-urban areas in Western Australia (WA).

Rabbits cause considerable losses to agricultural and horticultural industries. They can cause serious environmental problems, such as soil erosion and degradation of native vegetation. Rabbits also compete with native fauna for food and habitat.

Rabbits may be a problem or a nuisance in urban environments where they can damage lawns and gardens, buildings, garages, and sheds. Rabbits can also damage golf courses, sports grounds, and parkland reserves.

The options for control of rabbits in urban areas are more limited than in rural …

Rabbit Fencing To Protect Crops And Pastures, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

This factsheet outlines the use of fencing to protect crops and pasture from rabbits.

Rabbits cause an estimated loss of $217 million each year to Australian agricultural production and cause significant environmental damage. In Western Australia (WA), areas of native vegetation, particularly on sandy ridges that would otherwise be subject to wind erosion, have been retained on farms. Bush remnants are a major refuge habitat for rabbits, which can cause considerable damage to nearby pastures and crops. A measure of rabbit control can be achieved by poisoning around bush remnants in late summer or autumn, prior to seeding. To be …

Confined Paddock Feeding And Feedlotting Of Sheep, Department Of Primary Industries And Regional Development, Western Australia

Confinement feeding (also referred to as lot feeding or feedlotting) is an intensive feeding system in a confined area where all, or the majority of, feed and water is supplied to the contained animals. The department recommends using confinement feeding as part of a whole farm livestock, pasture and erosion management program.

We recommend having a confinement feeding system as an integral part of a whole farm livestock, pasture and erosion management program. Guides and resources that provide more detailed information are listed at the bottom of this fact sheet.

Sheep Feed Value Guide, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Sheep are supplementary fed for either survival or production purposes. Efficient supplementary feeding should aim to supply sheep with a diet that is sufficient in digestible energy and protein. We recommend testing feedstuffs, although the feed tables supplied here can be used to help roughly estimate the amount of grain and fodder required.

Knowing the value of different feedstuffs is critical when making decisions about livestock nutrition, for survival, maintenance and growth.

Supplementary feeding is a key part of a Western Australian (WA) sheep enterprise because most sheep systems are on annual pasture which is dry over the Mediterranean summer. …

Feral Goat, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

The goat (Capra hircus) was one of the first animals to be domesticated, 8 to 10 thousand years ago. Archaeological work indicates the earliest attempts at domestication were in dry hills surrounding the Mediterranean basin. The ability of goats to utilise the coarse browse of mountainous areas made them suitable for domestication, in preference to sheep. With large-scale domestication of goats throughout the world, goats escaped and established feral goat herds on most continents. Overgrazing by goats has caused severe environmental damage, worldwide.

Goats arrived in Australia with the first fleet. They were introduced to many areas by early settlers …

Rabbit Control: 1080 Versus Pindone, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

There are two toxins available for controlling pest rabbits in Western Australia: 1080 and pindone. This factsheet provides a brief summary of the main characteristics of both vertebrate pesticides. 1080 is generally the preferred toxin for rabbit control in Western Australia (WA).

Any attempt to reduce the impact of rabbits on the productivity of any agricultural enterprise (for example, pasture, crops, tree farms, horticulture) should be undertaken as part of a pest management plan.

This strategy should be proactive rather than reactive to a problem. It should also include a long term strategy for dealing with potential rabbit damage, including …

Effects Of Revegetation Approaches On Wetland Plant Community Reassembly Under Hydrologic Extremes, Maddie Houde, Karin Kettenring

Browse all Datasets

Active revegetation is often necessary to recover native plant communities in disturbed or degraded wetlands. However, active revegetation has been pursued less in wetlands than other ecosystems and thus, there are few established best practices to guide implementation. Additionally, wetland revegetation is challenging due to dynamic hydrology becoming more extreme and high invasive plant propagule pressure that can limit native plant recruitment and favor invasive plant dominance. In this study, we tested the efficacy of varied revegetation approaches on native plant reassembly and invasion resistance in semi-arid wetlands subject to seasonal hydrologic fluctuations. In a Great Salt Lake wetland in …

Root Lesion And Burrowing Nematodes And Their Management, Department Of Primary Industries And Regional Development, Western Australia

Roly Poly And Its Management, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Roly poly, also known as prickly saltwort or tumbleweed (Salsola australis), is a native species found throughout Australia. The dead plants can break off at ground level, forming the ‘tumbleweeds’ seen in movies.

Like most summer weeds, roly poly uses soil moisture and nutrients that would otherwise be available to the following crop. The time taken to clear uncontrolled plants can delay seeding.

Livestock will graze the young plants; however, they will not eat the mature plants and are injured by the prickly leaves.
