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 …

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.

Wild Oat Control With Hoegrass With And Without Oil, R. Madin, J. Buckley

Experimental Summaries - Plant Research

Trial 87NO08
All treatments except Combine + Oil yielded significantly better than the control. Control of wild oats with Grasp was superior to many other treatments and this was reflected in the yield.

Trial 87N009
All treatments yielded significantly better than the control however there was no difference between herbicides, rates of use or additives. The exception being 0.75 L Hoegrass +WA which yielded significantly less than Grasp + oil.

Crop Establishment, R. Madin, J. Buckley

Trial effect of timing of Roundup CT and Spray.Seed application and cultivation on crop establishment and growth.
87WH53, 87NO85

The general tendency was for yield to decrease as the time to seeding after Spray.Seed application increased.
For trial 87NO85 the site was a 'problem', heavy textured soil where crop emergence problems following glyphosate had been experienced in previous years.

Crop establishment - time of seeding following herbicide application.

Use of a knockdown herbicide greatly increased yield when compared to the unsprayed treatments. Further work is required to resolve contrasting results.
