Low Rainfall Pasture Programme, M Ewing
Low Rainfall Pasture Programme, M Ewing
Experimental Summaries - Plant Research
The Headquarters of dry land pasture project was transferred to Merredin from Perth for the 1980 season. The aim of the programme is to ascertain the place that legume pasture might play in the dryland farming system. It is aimed to test and introduce improved varieties of pasture species and develop management systems which will improve pasture production and persistence in the low rainfall areas of the wheatbelt. 1. Variety testing.

General Phosphorus Trials, R J. Lunt, J. W. Bowden
Experimental Summaries - Plant Research
The trial programme of past years was considerably reduced in size because of the absence of J.W. Bowden (Research Officer). Further, extensive drought conditions in the W.A. agricultural areas wiped out several trials.

Influence Of Planting System On Surface Soil, Physical Conditions And Soil Water Relations, D Tennant
Influence Of Planting System On Surface Soil, Physical Conditions And Soil Water Relations, D Tennant
Experimental Summaries - Plant Research
Influence of planting system on surface soil, physical conditions and soil water relations. The availability of soil water for crop use can this way be influenced by planting system. Various aspects of soil water relations were examined in varying detail at three sites - Wongan Hills, Avondale and Merredin, over the 1979 and 1980 growing seasons. Some of this soil water data are presented here. The Department of Agriculture initiated a programme in 1977 to investigate and compare crop performance under several planting systems. This project was part of this programme and had as its objectives: 1. Measurement of soil …

A. Inoculum Of The Take-All Fungus And Prediction Of Take-All. B. Hypovirulent Strains And Control Of Take-All., K Sivasithamparam
Experimental Summaries - Plant Research
Contents: A. Inoculum of the take-all fungus and the prediction of take-all. 1. Time of sampling 1a Newdegate 1b Badgingarra 1c Kulin 2. Inoculum from grass and wheat residues - Esperance. 3. Hypovirulent strains and control of take-all 3a Esperance, 3b Newdegate. Results from the preliminary studies which commenced in 1978 have shown several interesting trends in the behaviour of the field inoculum of the take-all fungus (TAF). "Disease severity Assay" has emerged as a potentially useful assay of field soil. This assay reflects the level of disease severity (on a 0-5 scale) caused by the resident inoculum of the …

Pasture Species Research, C. M. Francis
Experimental Summaries - Plant Research
EARLY MATURING MEDICS Early maturing Libyan lines with some tolerance to bluegreen aphids were sown at 6 sites, five in Western Australia and one in South Australia. Seed yield and hard seed data are currently being collated. Maturity and vigour was assessed at all sites and many of the new introductions are earlier than cv. Harbinger and its equal in vegetative growth. A much larger range (300 lines) was grown at Medina and will be introduced into country sites next year.
Kabatiella Research. In cooperation with Dr. D.L. Chatel, screening of introductions for resistance to Kabatiella caulivora continued in 1980. …
