Trials in Progress During 1973 observations were made on 11 small plot legume species· trials and 11 grazing trials. In 1974 the small plot trials will remain the same and the grazing trials will be reduced to 8. This report summarizes the results from the grazing trials under the following headings:- Seasonal Conditions. Grazing Experiments. 68M023 - Legume Grazing Management·Trial,.

Summary Of 1972 Seasonal Results "Decide" Superphosphate Rates On Pastures, J. W. Bowden

Experimental Summaries - Plant Research

A total of 53 pasture trials were topdressed. Of these, 37 trials were quantitatively assessed at different times during the growing season. Of the 15 wheat trials sown, only four trials gave useful results because of multiple drilling techniques used on most trials. Until the trial results have undergone comprehensive statistical analysis, no conclusions can be drawn. about the levels of response or "optimum" rates of superphosphate application at individual sites. However, because of the very short growing season in 1972 responses were generally poor. It appears that nil superphosphate application would have been optimum for animal production in the …

1973 Rates Of Phosphate On Lupin Yield, G Walton

Experimental Summaries - Plant Research

Comments on Results - New Land sites (Graphs 1, 2) - The three sites were very responsive with the point of inflexion about 600 kg/ha super rate (similar to 1972 result). The seed x super rate interaction shows the quicker response to super with higher seeding rates. Low Super Bank (800 kg/ha) (GRAPH 3) - The two sites showed very little response to super applied. On the Eradu sandplain no response to super for either Unicrop or Wheat. On the Watheroo yellow sandplain (73M015) the two lupin cultivers and the wheat gave different responses. High Super Bank (>1 OOOkg/ha) …

Annual Summary Of Experimental Results 1970-71 - Evaluation Of Pasture Species, G H. Walton

Experimental Summaries - Plant Research

During 1970 interest in the small ungrazed Legume Species Trials was reduced to ten trials located in the more troublesome areas. Five of the trials are on the sandy soils of the Midland Plain three trials are in Merredin-Southern·cross region, one is on deep sand at Tincurrin and the other is at Pindar. All thesites are sandy soils on which the sub clover strains appear to perform the best. The newer trials are investigating the value of sub clover cultivars such as Northam A,Mt Helena A, Shenton Park A, and Daglish. These trials will be the subject of a special …

Bulletin No 3547 - Kimberley Research Station - Progress Report 1968, Western Australian Department Of Agriculture

Bulletins - 3000 - 3999

Rivers flowing to the Gulf of Carpentaria and the Timor Sea have been estimated by hydrologists to carry about three times the water transported annually over the Murray drainage system and the South Eastern slopes which, together, comprise the highly settled agricultural areas of South Eastern Australia.

In 1945, the North Australian Development Committee recommended research in the Ord-Victoria rivers region as a first step toward ultimate agricultural development of this Northern potential and, in 1946, the Kim- berley Research Station commenced operations under the joint control of the Commonwealth Scientific and Industrial Research Organization and the Western Australian Department …

Cultivation : Does Haste Mean Waste?, H M. Fisher

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

Many farmers believe that increasing the speed of cultivation and seeding implements will cause deterioration of soils and reduced crop yields.

In a three-year trial on clover ley land at Wongan Hills higher cultivation speeds tended to increase rather than decrease wheat yields. There was some deterioration in the physical structure of the soil.
