Improving Feed Grains, Bruce P. Mullan
Improving Feed Grains, Bruce P. Mullan
Journal of the Department of Agriculture, Western Australia, Series 4
Clearly, to encourage grain growers to focus their production systems towards feed grains, it is important to first identify the reasons for variation in the nutritional value of grains and then to develop rapid, cheap, and accurate methods of measuring these factors. The analytical methods should ideally be suitable for application either at the site of grain delivery from the farm or within the place of stockfeed manufacture. This will mean the nutritional value of the grain can be known before it is used. The rational marketing of feed grains could then be achieved, with the benefits from more efficient …
Managing Lupin Anthracnose, Greg Shea, W A. Cowling, B J. Burchell, D Luckett, H Yang, Mark W. Sweetingham, Geoff J. Thomas
Managing Lupin Anthracnose, Greg Shea, W A. Cowling, B J. Burchell, D Luckett, H Yang, Mark W. Sweetingham, Geoff J. Thomas
Journal of the Department of Agriculture, Western Australia, Series 4
Anthracnose in lupins was first reported in commercial crops in Western Australia in September 1996. By October 1996, several thousand lupin breeding lines and wild types of 11 lupin species were sown in New Zealand for resistance screening. In 1997, resistance to anthracnose was confirmed in several breeding fines and commercial cultivars of narrow-leafed lupins (I. angustifolius), landraces of albus lupins (I. albus) and wild types of several other lupin species. Important information on critical seed infection levels and fungicide seed treatment has also been determined.
Transgenic Cotton Research Paves The Way For A New Industry In The Kimberley, Geoff Strickland, Amanda Annells
Transgenic Cotton Research Paves The Way For A New Industry In The Kimberley, Geoff Strickland, Amanda Annells
Journal of the Department of Agriculture, Western Australia, Series 4
The use of transgenic cotton varieties (INGARD®) in conjunction with t_x integrated pest management (IPM) systems in the Kimberley region is producing excellent yield and quality prospects for an emerging cotton industry in Western Australia. Geoff Strickland and Amanda Annells report on the value of transgenic cotton and the additional benefits being gained from the use of multi-faceted IPM systems.
Eradicating Virulent Footrot From Western Australia, R K. Mitchell
Eradicating Virulent Footrot From Western Australia, R K. Mitchell
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australia has a unique opportunity to eradicate virulent footrot from the State's sheep flock, with only 62 properties or 0.6 per cent of sheep properties currently in quarantine. The majority of Western Australian flocks are now free of virulent footrot, with targeted on-farm and abattoir surveillance used to detect the remaining properties affected by the disease. Bob Mitchell reports on how farmers, industry, and government are working together, with research playing an important part in the eradication campaign.
Carrot Export Growth Depends On Keeping Cavity Spot Under Control, Allan Mckay, Elaine Davison
Carrot Export Growth Depends On Keeping Cavity Spot Under Control, Allan Mckay, Elaine Davison
Journal of the Department of Agriculture, Western Australia, Series 4
Cavity spot is the most serious disease affecting carrot production in Ly Western Australia. With carrots now being the State's most important horticultural export, Agriculture Western Australia has undertaken extensive research to ensure the export market continues to grow.
Finding Western Australia's Most Profitable Merino Flocks, David Windsor
Finding Western Australia's Most Profitable Merino Flocks, David Windsor
Journal of the Department of Agriculture, Western Australia, Series 4
Wether trials across Western Australia are showing significant differences in Merino flock productivity, which have important implications for whole-farm profitability. David Windsor reports on how wool growers in the 21 st century can maximise productivity by combining superior management skills with the best available genetic material.
Profit From Pastures, Mark Callow, Martin Van Houtert
Profit From Pastures, Mark Callow, Martin Van Houtert
Journal of the Department of Agriculture, Western Australia, Series 4
The research program has made a major contribution to the improvement of pasture management techniques, which has, in turn, led to a gain in productivity for dairy farms in the south-west of Western Australia. Analysis has shown a 25 per cent improvement in pasture utilisation, an increase in the average number of cows milked from 155 to 192, an increase in average stocking rates from 0.9 to 1.2 cows per hectare, and increased income from milk sales by $600 per hectare. There are still areas for improvement in sustainability, productivity, and profitability, but the success to date is a credit …
Accelerating Variety Release With Double Haploids, Sue Broughton
Accelerating Variety Release With Double Haploids, Sue Broughton
Journal of the Department of Agriculture, Western Australia, Series 4
The use of plant tissue culture to produce special lines called doubled haploids is reducing the time taken to breed new varieties of cereal crops by up to three years. Sue Broughton outlines what doubled haploids are, how they are produced, and why they have been able to short circuit the usual lengthy breeding process.
