To evaluate the response of lupin varieties to a range of sowing dates when grown in high rainfall/long growing season environments.

Trial 90ES8

Lupin time of sowing x variety.

Location: Scaddan

To evaluate the response of lupin varieties to a range of sowing dates.

Ecology And Control Of Grass Weeds In Cereal Pasture Rotations In The Great Southern Region., A. Wallace Jan 1990

Ecology And Control Of Grass Weeds In Cereal Pasture Rotations In The Great Southern Region., A. Wallace

Experimental Summaries - Plant Research

Silvergrass control.

Trial 90AB11

Location: Great Southern Agricultural Research Institute - Katanning.

The site was an established silvergrass dominant pasture on a light sandy soil.

Trial 90KA95

Location: Great Southern Agricultural Research Institute - Katanning

The site was an established silvergrass dominant pasture on a medium clay soil.

Trial 90KA96

Location: Great Southern Agricultural Research Institute - Katanning

The site was an established silvergrass dominant pasture on heavy (Moort type) clay soil.

Simazine was found to be very active against silvergrass on the light sandy site and all rates applied gave complete control. There were some late germinations which enabled …


Investigating Poor Pasture Productivity., J. W. Bowden, R. J. Lunt, C. Broun Jan 1990

Investigating Poor Pasture Productivity., J. W. Bowden, R. J. Lunt, C. Broun

Experimental Summaries - Plant Research

Trial 90N06

Location: West Dale

To determine the reason for poor pasture productivity in medium rainfall zone. Specifically why the pastures are dominated by the poorly productive species Trifolium suffocatum and why there was a large response to phosphorous fertilizer at 50 ppm P in the soil.


Systems For Early Sowing Of Wheat In Low Rainfall Zones., Nicole Kerr, Glenn Adam Jan 1990

Systems For Early Sowing Of Wheat In Low Rainfall Zones., Nicole Kerr, Glenn Adam

Experimental Summaries - Plant Research

Aims:

(i) use available climatic data to determine when breaks are likely to occur, and assess the risk of crop failure from 'false breaks'.

(ii) determine optimum methods of early crop establishment on a number of soil types, particularly massive earth soils.

(iii) determine the yield advantages of early planting of cereals, and sowing date * variety interactions. (iv) increase adoption of early sowing technology throughout the north-eastern wheatbelt.

Trial 90GE7, 90GE8, 90NM1 and 90GE10

Time of sowing * variety trials.

Location: Balla, North Mullewa and Morawa.

All of the trials the following design: 3 sowing dates (mid May, late …
