Matching Tractors And Implements, I W. Grevis-James

Journal of the Department of Agriculture, Western Australia, Series 4

Tractor and implement matching involves balancing implement load characteristics with tractor output characteristics to obtain the best output from the combination. Too much or too little can be costly.

Lupin Yields Are Not What They Should Be : Viewpoint, M Ferguson, S. Trevenen

Journal of the Department of Agriculture, Western Australia, Series 4

Mike Ferguson has been in charge of the Three Springs office of the Department of Agriculture since 1977.

Based on trials he has done and others he has seen, he believes farmers can greatly increase their yield of lupins.

Nitrogen Fertilisers For Rape (Brassica Campestris And B Napus) And Wheat In Western Australia, M G. Mason

Technical Bulletins

Absolute yield increases tended to be greater for wheat than rape at 63 per cent of the nitrogen responsive sites, but percentage yield increases and rate of N for maximum yield tended to be greater for rape than for wheat. When average response curves over all trials were considered, there was little difference between the two crops in terms of percentage responsiveness and N rate for maximum yield in areas with less than 460 mm average rainfall, but in higher rainfall areas the response to N was higher.

Fumigating A Farm To Control Grain Insects, J H. Moulden

Journal of the Department of Agriculture, Western Australia, Series 4

During the past year, two major projects for control of grain insects were organised on Western Australian farms. Both excercises aimed to eradicate grain pests which would have seriously threatened grain exports if they had become established.

The fumigation was done jointly by the Entemology branch of the Department of Agriculture, and the Agricultural Protection Board.

Ryegrass Toxicity Organism Found On Other Grasses, D L. Chatel, J. L. Wise, A. G. Marfleet

Journal of the Department of Agriculture, Western Australia, Series 4

Yellow slime disease caused by Corynebacterium sp. has recently been found in three grass species.

The diseased grasses were found in the field growing with each other and with affected toxic annual ryegrass.

Cereal, Pasture Legume And Water Supply Prospects At Forrestania : Results Of Experimental Work East Of Hyden, Western Australia, T E. Mcdowell, M G. Mason, J W. Gartrell, William J. Toms, I A F Laing

Technical Bulletins

The agricultural potential of the Forrestania area appears at least equal to that of much of the settled eastern wheatbelt. The scrubplain soils of the Forrestania area have an average yield potential of at least 1 000 kg/ha wheat and carrying capacity of 1.8 to 3.7 sheep per hectare on improved pastures. The use of clover ley rotations would maintain these levels of potential yield. Partial crop failures caused by adverse seasonal conditions could be expected 10 years in every 100.

Replacing Farm Machinery, R Crossman

Journal of the Department of Agriculture, Western Australia, Series 4

In talking of machinery replacement it seems implied that the replacement items of plant are bigger and therefore better than their predecessers. It is also implied that plant replacement is becoming more costly.

Before any decision to replace machinery, the reason for replacement should be carefully considered.

There may be alternatives to the bigger and better solution.

Calibration Of Boom Sprays, J R. Peirce

Journal of the Department of Agriculture, Western Australia, Series 4

Boom sprays have become increasingly common on Western Australian farms, allowing farmers to take advantage of modern herbicided.

Most boom sprays used on farms have 50 cm nozzle spacings and require calibrating regularily to ensure accurate herbicide application.

By following these steps, the boom will deliver accurate amounts of herbicide.

The Place For Annual Brome Grass, G W. Anderson

Journal of the Department of Agriculture, Western Australia, Series 4

Grasses in the anual pastures of southern Australia are particularly important early in the growing season.

The main grass sown, has been annual rygrass, but concerns are emerging with 'annual ryegrass toxicity' and and 'in crop' competition.

This work looks at the role of annual brome grass in pastures.
