Cereal Crop Tolerance To Herbicides, D Bowran, R Madin, A Lindsay

Experimental Summaries - Plant Research

The 1984 experimental programme was a continuation of that started in 1981. The programme was aimed at evaluating the major herbicides in current use for cereals as well as new herbicides against the recommended varieties at three main sites, these being Wongan Hills, Merredin and Mt Barker. In addition Stage 4 breeding lines were evaluated against the same herbicides but only at Wongan Hills. The herbicides used and their rates and time of application are presented in Table 1. Herbicides were applied at both the recommended and twice the recommended rates of application, except in the breeding line trial where …

Foliar Disease Of Wheat, A. G. P. Brown

Experimental Summaries - Plant Research

Wheat leaf diseases were at much reduced levels in 1984. This may have been caused by prolonged summer rain prematurely setting off dispersal of spores and also initiating microbiological breakdown of stubble residues. No survey was carried out in 1984 but a good indication of the seasonal effect can be gained by noting that in the spray-timing experiment at Badgingarra disease levels were extremely low until the end of August some 90 days after sowing.

Soil Acidity Survey. Lime Responses In The Central Wheatbelt, P J. Dolling

Experimental Summaries - Plant Research

Introduction: In 1984 a project commenced to examine the influence of soil acidity on barley production in the main barley growing areas of Western Australia. To carry out some of the projects objectives a soil survey was carried out.

Aims: 1. To select nine sites for liming trials in 1985. 2. To obtain more information about the soil acidity problem in the medium rainfall region of W.A. 3. To determine if there is a relationship between the pH and aluminium content of the soil.

Survey details: Area covered - Katanning and Narrogin District Office (DO) areas. Sampling period - Mid …

84M5, 84M6, 84M7. Location: Merredin Research Station Merredin, Western Australia. Three experiments were conducted to measure the productivity and water use of alternative wheatbelt crop species on contrasting soil types in a dry mediterranean environment. Crop species investigated were wheat, barley, cereal rye, narrow leafed lupin and field pea. These were grown on three contrasting soil types, a red-brown earth, a sandy loam over clay and a deep loamy sand; all soils occurring within close proximity to each other. Detailed measurements were made of meteorological conditions, dry matter production, leaf area, root growth, soil water profiles, light interception and plant …
