Clover Scorch: Summary Of 1974 Experiments, D. L. Chatel

Experimental Summaries - Plant Research

Experiments reported in this summary were conducted jointly with CM Francis. 1. Variety Screening - During 1974, two hundred and fifty-four varieties were screened for resistance to Kabatiella caulivora in small plots at Denmark. The test varieties included 49 that showed up as promising in previous years. The remainder included all the untested accessions for which sufficient seed was available. There were 239 sub. sp. Subterranean, 14 sub, sp. Yanninicum and 1 Brachycalycinum... - The plots were periodically inoculated with infected debris and rated for disease severity on a number of occasions. Lists of the most and least resistant clovers …

The Place Of Lucerne In Western Australian Agriculture, N J. Halse, C. M. Francis

Journal of the Department of Agriculture, Western Australia, Series 4

Lucerne, the world's most important fodder legume, has never won largescale acceptance in West Australian farming, largely because of our success with productive subterranean clover pastures. But recent disease problems on sub. clover stands have led to greater interest in alternative species, especially lucerne, for higher rainfall areas.

This article summarises our knowledge of lucerne establishment and management in W.A. and reviews current research aimed at achieving better results from lucerne.

Grain Moisture Problems On The South Coast, J A. Parish, G. H. Jones

Journal of the Department of Agriculture, Western Australia, Series 4

In most West Australian grain growing districts high temperatures and dry weather at grain maturation are ideal for harvesting and enable delivery of grain with acceptable moisture levels. Grain from W.A. is known in world markets as a good quality dry product which is unlikely to deteriorate in storage. However, growers in coastal areas and particularly those south of Narrogin sometimes have trouble harvesting grain below the receival limit of 12 per cent moisture.

Linseed : A Forgotten Crop, M L. Poole, R. J. Guyton, H. M. Fisher

Journal of the Department of Agriculture, Western Australia, Series 4

Linseed has become a forgotten crop in Western Australia. From a peak production of 6 200 tonnes from 12 500 hectares in 1969, and an apparently bright future, it dwindled to a bare 80 tonnes from 250 hectares in 1973.

This article looks at some of the reasons for this decline and, with linseed fetching all-time record prices on world markets, gives reasons why the crop should be grown.

Experimental Summaries - Plant Research

Of the four time of planting trials twodefinitely showed superiority of earlier seeding (73BA5, 73E6). The two trials in the Southwest (73BR14 and 73MT7) gave highest yields with June sowing compared to May. Three trials (73BR14, 73E6 and 73BA5) appear to have a Variety x Time interaction for plant density, but no definite trend for either Uniharvest or Unicrop although later sowing reduced plant density. Seeding rates in excess of 82 kg/ha gave the highest yields in all trials. The rate of seeding experiments (73BA5 and 73MT7) show that the best crop density for yield (graph) lies between 8 and …

Wheat Quality In W.A, J A. Parish

Journal of the Department of Agriculture, Western Australia, Series 4

Three separate quality classes or categories of wheat are now received by C.B.H. These are a soft biscuit wheat, a hard bread wheat and a mixed grain suitable as a filler wheat in bread-making and for making noodles.

In this article the basis of quality differences between these classes of wheat is described and some of the terms and concepts used in distinguishing between cultivars (varieties) and classes of wheat are discussed.

Market Prospects For Rapeseed : 1972-73, R J. Guyton

Journal of the Department of Agriculture, Western Australia, Series 4

Interest in rapeseed as an alternative crop in the agricultural region of Western Australia was reflected in the area sown in 1971, some 70,000 acres, and an initial export contract of 10,000 tons made in January 1972.

This market report draws upon information released by the Department of Primary Industry and Department of Trade and Industry (both located in Canberra) and research within the Department of Agriculture. Its purpose is to outline future prospects for rapeseed as an aid to decision making for the 1972 season.

Experimental Summaries - Plant Research

The 1972 experimental results provide a good comparison between Unicrop and Uniharvest lupin under low rainfall conditions. While most trial results have to be examined in the knowledge of low rainfall confounded with high weed competition, some useful and practical conclusions can be drawn. The following table summarises the best yield obtained for the lupin varieties at each site. 72GE11, 72GE12, 72GE13, 72GE14, 72LG7, 72LG10, 72MO10, 72MT33, 72NO9, 72NO10, 72TS10,

Kimberley Research Station Review Of Progress, 1968-71, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

The potential for harnessing northern rivers flowing to the Gulf of Carpentaria and the Timor Sea was realised many years ago.

These rivers together are estimated to carry about three times the water transported annually over the Murray drainage system and the South Eastern slopes, which comprise the closely settled agricultural areas of South Eastern Australia.

The Kimberley Research Station was established in 1946 to investigate the potential for irrigated agriculture in the Ord River valley. This is a review of the Station's sixth progress report which is being published as Department of Agriculture Bulletin No. 3861.
