Subterranean Clover In W.A. 1. The Current Situation, B J. Quinlivan, C. M. Francis

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

From small beginnings some 50 or more years ago subterranean clover has come to dominate the pasture scene in Western Australia. Of the 7 000 000 hectares of sown pasture all but some 500 000 are sown to subterranean clover. Further, it is estimated that there remains an area of similar size still to be sown, although in some instances these future sowings will be possible only if suitable varieties are available.

Clearing and pasture development within the various agricultural regions of the State took place, as a rule, within quite clearly defined time intervals and the varieties selected for …

1976 Sunflower-Safflower Irrigated Variety Trial 1976-1977, G J. Parlevliet

Experimental Summaries - Plant Research

In 1975/76 two varieties of sunflower, Hysun 10 and Hysun 20, as well as Safflower (Gila) were grown in a large alternative crop demonstration. Results were sufficiently good to warrant more and closer examination. This led to the present variety trial using varieties suggested by Mr. M. Poole. The aim was to evaluate six sunflower varieties and one safflower. The work was carried out in the light of reduced profitability of peas, beans and some fruit crops. This results in a number of growers having irrigation water and equipment under-employed. Other farmers are after a crop which will give them …

Subterranean Clover In W.A. 2. Characteristics Required For Agronomic Success, C M. Francis, B. J. Quinlivan, N. J. Halse, D. A. Nicholas

Development of subterranean clover varieties is a rapidly changing scene, particularly in terms of farmer acceptance, disease and persistency problems. This is only to be expected, because this is an agricultural plant of only some 50 to 70 years standing, whereas many other pasture plants have been in common use for thousands of years.

Grain Crop Varieties For Western Australia, H M. Fisher

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

Recommendations for grain crop varieties grown in Western Australia are based on the results of field trials carried out each year by the Department of Agriculture at some 50 sites throughout the agricultural areas.

New varieties are tested directly against existing commercial varieties in large scale field trials for several years. Yield and quality results are analysed and market requirements are studied before recommendations are formulated.

This article gives information on the varieties of a range of crops now recommended for growing in Western Australia.
