Evaluation Of New Pasture Legume Species In Terms Of Summer Feeding Value And Effects On Wool Production., S E. Flecker, C W. Thorn, J. B. Rowe, Tess Casson

Experimental Summaries - Plant Research

86KA71, Pasture legumes improve the feeding value of summer pastures in a mediterranean-type environment by maintaining the protein intake of grazing animals over the dry summer period, much of which comes from the ingestion of legume burr (A.D. Wilson and N.L. Hindley, 1968). Some of the most important species of pasture legumes to have been released commercially are Trifolium subterraneum (sub.clover), Medicago truncatula (barrel medic) and Medicago polymorpha (burr medic) (D.B. Purser, G.B. Taylor and W.J. Collins, 1987). What little information is available on the feeding value of these species suggests that barrel medic pod (H. Brownlee, 1973) and dry …

Trial 65sg5, I Rowland., W Hawkins

Experimental Summaries - Plant Research

Trial 65SG5. Location - Paddock H5 on Salmon Gum Research Station

Cleared in 1962, then cropped until the start of the trial in 1968. Two of the four blocks were sown to Cyprus Barrel medic which is topdressed with superphosphate. The other two blocks regenerate volunteer pasture which is not topdressed. In 1984 all pasture plots were sown to SERENA medic. This grew exceptionally well in 1984 and set a lot of seed. In 1987 field peas were introduced into 4 reps of an existing medic: crop rotation.

Rates, Times And Sources Of Nitrogen On Wheat, J W. Bowden

Experimental Summaries - Plant Research

Trial 87WH51

Location: Wongan Hills Research Station.

This trial was put onto a site adjacent to Mel Mason's source of nitrogen trial and the CSIRO, 15 N plots to provide some explanation of the results from the limited treatments in those trials. They were designed to monitor soil/fertiliser nitrogen transformations with time. Unfortunately the site of this trial was variable. The end most similar to the other trials was deeper and sandier and stored less water than the other and where crop growth was far better.

Isoproturon Evaluation - Timing Of Application On Efficacy And Crop Damage., R. Madin, J. Buckley

Experimental Summaries - Plant Research

The trial was effectively a tolerance trial. Best overall weed control was achieved with Glean and the higher rates of Isoproturon which in turn gave best control as a pre-plant, incorporated treatment.

Post Emergence Weed Control In Lupins., R. Madin, J. Buckley

Experimental Summaries - Plant Research

As a general assessment in can be said that Tigrex is a safe and efficient herbicide for control of radish in wheat. Brodal alone was generally unsatisfactory for radish control. While Diuron + Brodal was safe and efficient, Ally and Brodal should not be used together. Diuron + MCPA gave poorer control than one would normally expect.

Control Of Peas And Lupins In Wheat, J. R. Peirce, B. J. Rayner

Experimental Summaries - Plant Research

Trial 87A29

Lupins were easier to kill than peas.

Glean applied pre-sowing gave very poor control of both peas and lupins.

The treatment using higher rates of 2,4-D amine in diuron mix also caused lower yields.

The Tordon 242 treatment appeared to cause some yield depression.

Control Of Prickly Saltwort (Salsola Kali) In Pasture., G. Fleay, R. Ramm

Experimental Summaries - Plant Research

Trial 87LG65

Glean post-em @ 10 and 15 g/ha gave good control.

A later trial gave good control with Garlon 4800 or 2,4-D amine when sheep grazed the weed after treatment. Considerable pasture damage would be done with all chemicals during the growing season.
