The Effects Of Tillage Implements On Cereal Yields, H M. Fisher
The Effects Of Tillage Implements On Cereal Yields, H M. Fisher
Journal of the Department of Agriculture, Western Australia, Series 4
Careful soil preparation is essential for cereal crops grown without fallow on clover ley land.
Crops give better yields where the land is broken up with a mouldboard or disc plough rather than a scarifier or similar machine.
The implements differ appreciably in their capacity to control weed growth and this is largely responsible for variations in cereal yields. "Takeall" disease is reduced by efficient weed control.

Check Your Milking Machine, T Pavy
Journal of the Department of Agriculture, Western Australia, Series 4
MILKING machine efficiency testing carried out by officers of the Department of Agriculture's Dairying Division have shown that many machines are not up to standard.
One reason for this is that farmers do not check their machines regularly.

Irrigating Dry Season Crops In The Ord Valley : How To Prepare Land For Sowing, D F. Beech
Journal of the Department of Agriculture, Western Australia, Series 4
THE best way to grow dry season crops of safflower, linseed and rapeseed under irrigation in the Ord Valley is by sowing on to broad flat ridges, separated by small furrows 3 ft. 6 in. apart.
This system of sowing is called the "corrugation" method.
Water Conservation On The Farm, John W. Lewis
Water Conservation On The Farm, John W. Lewis
Journal of the Department of Agriculture, Western Australia, Series 4
SMALL scale conservation of water for agricultural use is becoming increasingly important throughout Australia.
As land development intensifies, it is natural that farmers turn to more dams and earthen tanks for stock water and irrigation.
Adequate water is essential to supply the carrying capacities made possible by improved pastures, and where greater quantities of water can be stored, fodder crops, pastures, orchards and vegetables can be irrigated.

Getting The Best From Your Sewing Machine, O. Evans Scott
Getting The Best From Your Sewing Machine, O. Evans Scott
Journal of the Department of Agriculture, Western Australia, Series 4
"NEXT to the plough, this is perhaps humanity's most blessed instrument." (Louis Antoine Godey.)
In some homes the sewing machine is the most sadly neglected and ill-used servant. It is often left set up, exposed to dust, dampness and scratching, used as a table and otherwise abused.
It is not right to have a machine stitching imperfectly and noisily and used for long periods without maintenance when a little attention can keep it performing quietly and efficiently.
Automatic Waterers For Day Old Chickens, P Smetana, W. Ward
Automatic Waterers For Day Old Chickens, P Smetana, W. Ward
Journal of the Department of Agriculture, Western Australia, Series 4
ONE of the most tedious and time consuming tasks on a poultry farm is the provision of water to chicks from day old up to the age of three or four weeks.
Most poultry farmers use half-gallon glass fonts with metal bases for the first few weeks, until the chicks are old enough to use the automatic watering system usually situated along one wall of the brooder house.
This cumbersome glass font system can be replaced by the cheap and easily installed automatic watering system described below. This system has already been adopted by several local poultry farmers.

Tractor Testing In Australia. Part 2, G H. Vasey, W. F. Baillie
Tractor Testing In Australia. Part 2, G H. Vasey, W. F. Baillie
Journal of the Department of Agriculture, Western Australia, Series 4
AUSTRALIAN test procedures, though differing: in some details, and in some ways going further and telling more about the tractor, conform in essentials to overseas standards.
The tests are in four main parts—
(a) the physical properties of the tractor;
(b) the power of the engine, and its stationary outlets—the belt and the p.t.o;
(c) the power on the drawbar when working on a formalised test surface or track;
(d) the reliability of the tractor when running under test, and its condition after the test.

Tractor Testing In Australia, G H. Vasey, W. F. Baillie
Journal of the Department of Agriculture, Western Australia, Series 4
AUSTRALIA is one of several countries that have set up "official" tractor testing schemes.
These schemes mean testing stations that, while providing a testing service for both the manufacturing industry and the consumer, in effect mainly the farming industries, are independent of either.

Bulk Handling Of Superphosphate, H G. Cariss
Bulk Handling Of Superphosphate, H G. Cariss
Journal of the Department of Agriculture, Western Australia, Series 4
A MAJOR factor in our agricultural production is the outlay for fertilisers, including the cost of their application to the land.
Any means which can be employed to reduce these costs are therefore of extreme importance to the State's agriculture.
The bulk-handling of fertilisers could be one way of reducing these costs to the farmer.
