Results from trials comparing the growth and persistence of a number of annual pasture legumes in 1973 are presented in this report. Rainfall conditions during the year are described briefly and a table of annual and growing season rainfall at relevant centres is appended. The experiments are grouped as follows according to average annual rainfall:- Zone A - Average annual rainfall 400 mm. Zone B - Average annual rainfall 345 - 400 mm. Zone C - Average annual rainfall 345 mm. and then further on soil type. 70GE4, 70ME3, 70ME4, 70NA3, 70TS2, 70TS5, 71LG16, 71TS22, 72LG3, 72LG26,


1973 Time Of Planting And Rate Of Seeding On Lupin Yield, G Walton Jan 1973

1973 Time Of Planting And Rate Of Seeding On Lupin Yield, G Walton

Experimental Summaries - Plant Research

Of the four time of planting trials two definitely 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 …

Summary Of 1972 Seasonal Results "Decide" Superphosphate Rates On Pastures, J. W. Bowden Jan 1973

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 Jan 1973

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) …

"1970· Progress Eight of the 5 unreplicated trials were cropped without fertiliser. Seven were harvested (severe weed infestation ruined 66KA 7). Three trials left under pasture responded to the fertiliser treatments and were cut for dry matter production. The remaining four trials left under pasture grew badly, became weed dominant and were not rated for growth differences between treatments or cut for dry matter production. The replicated trials at Avondale and Newdegate were also cropped, without fertiliser. The replicated trials at Wongan Hills Research Station and Chapman did not visually respond to treatments and were not cut. 69WHl5 succumbed to …

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 …


Bulletin No 32 - Noxious Weeds And Poison Plants, Department Of Agriculture, Western Australia Jan 1910

Bulletin No 32 - Noxious Weeds And Poison Plants, Department Of Agriculture, Western Australia

Bulletins 1 - 2999

Many settlers, new to this State, find some difficulty in distinguishing those vegetable pests which are classed as noxious weeds, the eradication of which is made compulsory under the Noxious Weeds Act of 1904.

In order to facilitate the ready recognition of the plants which are the least familiar, the Department of Agriculture has prepared this Bulletin, giving illustrations of the several varieties which have been gazetted as noxious. these are: - Stinkwort, Bathurst Burr, Noogoorn Burr, Nut Bramble, Spanish Radish, Prickly Pear, Apple of Sodom, sweet Briar, Wild Bramble, Star Thistle (purple), Double Gee and Water hyacinth.
