Hard Seeds In Lupins, B J. Quinlivan Jan 1962

Hard Seeds In Lupins, B J. Quinlivan

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

A study of hard seeds in the W.A. blue lupin is yielding some interesting facts about this important survival mechanism of pasture plants.

The knowledge gained will be useful in future pasture plant breeding projects.

SOME interesting facts on hard seeds in lupins have come from experiments commenced several years ago.

This article outlines the reasons for the experiments and the results with lupins so far.

Subsequent articles will cover subterranean clover and techniques for softening hard seeds in both species before planting.


Root Diseases In Wheat On Clover Ley : Factors Under Investigation. 5. The Evaluation Of Fungicidal Treatments, S C. Chambers Jan 1962

Root Diseases In Wheat On Clover Ley : Factors Under Investigation. 5. The Evaluation Of Fungicidal Treatments, S C. Chambers

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

The use of fungicides, either as seed or soil dressings, for the control of root rotting diseases of wheat, was examined in a series of field experiments.

Results suggest that seed dressings have no effect on the incidence of root rotting fungi in the mature crop.

When fungicides were applied to the soil, a reduction in the incidence of take-all was noted in one experiment, but the same treatments had toxic effects on plants in a second similar experiment.

Rice Growing In The Ord River Valley, C B. Langfield

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

THE first commercial rice crop in the Ord River Valley was planted late in I960 and plans are in hand for some 35,000 acres of land to be subdivided for irrigation settlement by 1964, with rice as a major crop.


Castor Beans : Ricinus Communis Linn, T Pavy Jan 1961

Castor Beans : Ricinus Communis Linn, T Pavy

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

MANY people have seen the wild castor oil plants around the metropolitan area, growing in rubbish dumps, and waste lands.

But they have not realised that the demand for castor oil has been increasing over the last 15 years.

Although one of its main uses is in the lubrication of jet engines, it is also used in plastics, special low temperature lubricants, hydraulic fluids, paints, varnishes, textiles and pharmaceutics.


Potato Variety Trial, James P. Fallon, G. C. De Haan Jan 1961

Potato Variety Trial, James P. Fallon, G. C. De Haan

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

DELAWARE has been the only variety of Potato grown commercially in Western Australia. This is due to the fact that in the past an early maturing variety with a short dormancy period has been required to suit both hill plantings and swamp crops.

However, with the advent of sprinkler irrigation and hence better control of moisture and growing conditions, the need for early maturing varieties has ceased to exist in some districts.

There has been consequently an increasing interest in testing varieties which have proved high yielding and of good quality in other parts of the world.


The Use Of Nitrogenous Fertilisers For Cereal Grain Production In Western Australia, William John Toms, G. H. Burvill Jan 1961

The Use Of Nitrogenous Fertilisers For Cereal Grain Production In Western Australia, William John Toms, G. H. Burvill

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

NITROGENOUS fertilisers have so far been little used in Western Australia for wheat, oats and barley grown for grain.

However, profitable results can follow their use under some conditions. Farmers who have seen field experiments are now interested in the use of nitrogenous fertilisers.Further interest will be stimulated by recent reductions in price.

This article answers common questions asked by farmers about nitrogenous fertilisers for cereals. It is based on over 100 experiments conducted by the Department of Agriculture during the past 30 years.


Weed Control In Cereals : Aerial Spraying Trials, G R W Meadly Jan 1961

Weed Control In Cereals : Aerial Spraying Trials, G R W Meadly

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

SPRAYING cereal crops for weed control is now standard farming practice in Western Australia. Almost 500,000 acres of cereal crops, mainly wheat, are sprayed each year, and approximately three-quarters of this area is treated by aircraft.

Recent trials have shown that aerial application of 'extra low" volumes of hormone-like herbicides, with oil or water solvents, does not damage cereals if spraying is done at the right stage of growth.


Bare Patch And Poor Emergence Of Cereals : Factors Under Investigation. 2. Depth Of Planting, S C. Chambers Jan 1961

Bare Patch And Poor Emergence Of Cereals : Factors Under Investigation. 2. Depth Of Planting, S C. Chambers

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

DEPTH of planting appears to have an important influence upon the emergence of a cereal crop. Increasing the depth by one inch within the range 1-5 inches, not only depressed the emergence counts of wheat seedlings, but also increased the number which emerged abnormally.


Net Blotch Of Barley, Department Of Agriculture, Western Australia Jan 1961

Net Blotch Of Barley, Department Of Agriculture, Western Australia

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

NET Blotch is the commonest disease of barley in Western Australia, attacking all commercial varieties and causing considerable damage to foliage of maturing crops.

Despite its prevalence, net blotch is rarely the cause of a serious crop loss.

Spread Super For Cereal Crops, T E. Mcdowell, J. A. C. Smith, W. J. Toms, M. D. Carroll

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

THE use of bulk superphosphate broadcast direct on to the paddocks is a new method of reducing fertiliser costs.

But it has long been known that broadcasting phosphate is less efficient than drilling it in with the seed.

The experiment reported here was designed to demonstrate this point.


Wheat Quality, Department Of Agriculture, Western Australia Jan 1961

Wheat Quality, Department Of Agriculture, Western Australia

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

IN August, 1956, the Australian Agricultural Council agreed that, as a first step in the further examination of all aspects of the subject of wheat quality in Australia, a conference of all interested parties should be convened by the Department of Primary Industry.


Wheat Variety Trials On Research Stations, J T. Reeves, J. L. Mcmullan Jan 1961

Wheat Variety Trials On Research Stations, J T. Reeves, J. L. Mcmullan

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

THE results of wheat variety trials at seven Research Stations in the medium and low rainfall areas for the years 1957, 1958 and 1959 are presented and discussed.

The trials are designed to give information on yield and flour quality of promising crossbreds originating from local breeding programmes and newly produced varieties from other parts of Australia.

Large scale variety trials are the final tests in the long process of selection and testing which is essential before a new crossbred can be released.

The new wheats are compared with standard ones under different conditions of soil and climate.

Diseases Recorded On Cereals, Grasses And Pasture Legumes In Western Australia, S C. Chambers

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

This list constitutes a revision of portion of the census published by Came (1925) and supplemented by the same author in 1927.

It also contains records of diseases identified in the period between these earlier publications and December 31, 1959.

The list is divided into two sections, the first dealing with pasture legumes and the second with cereals and grasses.

The sections are arranged alphabetically according to the botanical names of the host plants. In general, the viral, bacterial, fungal and nematodal diseases and physiological disorders are listed in that order.


Safflower : An Oil Crop For The Kimberleys, D F. Beech Jan 1960

Safflower : An Oil Crop For The Kimberleys, D F. Beech

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

EXPERIMENTS with irrigated safflower carried out at the Kimberley Research Station have shown that the crop is well adapted to the local conditions.

In recent years yields of 2,000 to 3,000 lb. per acre have been generally obtained. Oil content of the main variety under trial varied between 33 and 35 per cent.

Locally produced safflower oil could help to make the Australian paint industry largely independent of imports.

Safflower meal is a protein-rich concentrate and could have considerable impact on the Kimberley cattle industry.

Safflower is likely to play an important part in the early development of irrigation agriculture …


Tobacco Production In Western Australia, A E. Baker Jan 1960

Tobacco Production In Western Australia, A E. Baker

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

THE annual consumption of manufactured tobacco in Australia is in the vicinity of 55,000,000 pounds.

Although the public is well acquainted with the use of tobacco for smoking, many people are unaware of the care and attention required to grow such a crop.

The following article attempts to outline the conditions and methods as applied to tobacco production in Western Australia.


The Development Of Western Australian Sand Plain Soils For Agriculture, Richard Philip Roberts, F. L. Shier Jan 1960

The Development Of Western Australian Sand Plain Soils For Agriculture, Richard Philip Roberts, F. L. Shier

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

IN a recently published economic survey of the Australian wheat growing industry, it was reported that nearly two-thirds of the farms surveyed in Western Australia were located on lateritic "sand plain."

As a random selection was made of the eighty farms that were visited it is reasonable to conclude that a similar proportion of all the State's wheat producing farms are on that type of country.

This constitutes a remarkable change from the earlier days of wheat belt settlement when the sand plain soils were regarded as virtually useless and by-passed for development.

It is the purpose of this article …


Tobacco Seed-Bed Management, A E. Baker Jan 1960

Tobacco Seed-Bed Management, A E. Baker

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

A SUCCESSFUL tobacco crop depends initially on an ample supply of well-grown, disease-free seedlings available early in the planting season.

If planting is held up due to a poor supply of seedlings, the resulting crop will not be grown in the most favourable part of the season. Late-grown crops nearly always give low returns.


Insects And Mites Found Attacking Cereal Crops In Western Australia, Clee Francis Howard Jenkins Jan 1960

Insects And Mites Found Attacking Cereal Crops In Western Australia, Clee Francis Howard Jenkins

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

ONE of the most important factors influencing Western Australian agriculture in the last 20 years has been the development of permanent pastures together with the associated practice of ley farming.

Although the increased use of pasture plants, and particularly subterranean clover, has increased the general fertility of many areas it has also accentuated various problems, including those relating to insect control.

Summer fallow was a strong deterrent to such pests as the red-legged earth mite, the lucerne flea, and webworm and these and several other creatures have shown a tendency to increase under new farming methods.


Kimberley Research Station : A Progress Report, Department Of Agriculture, Western Australia Jan 1960

Kimberley Research Station : A Progress Report, Department Of Agriculture, Western Australia

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

INTEREST in the agricultural potential of the Kimberley region in Western Australia dates from its early exploration and settlement in the last century.

Several farming development schemes were considered for the area, but were never implemented.

This could be mainly attributable to lack of knowledge of agricultural potentialities, limitations of the local environment and ways of exploiting the local environment.

Up to the present the economy of the region is almost entirely based upon the extensive production of beef and to a lesser extent, wool.


Seed Storage In Relation To Germination, G R W Meadly Jan 1960

Seed Storage In Relation To Germination, G R W Meadly

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

WE are often asked how long seed can be stored and remain suitable for sowing.

There is no single answer as the period depends on a number of factors, including the type of seed, its condition at the time of storing and the nature of the storage.


Scald Of Barley, S C. Chambers Jan 1960

Scald Of Barley, S C. Chambers

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

SCALD is a common disease of barley during late winter-early spring and causes considerable damage to the foliage of many crops.

The fungus Rhynchosporium secalis is responsible for this disease which is very prevalent in all barley growing districts.


Weed Control In Cereals, G R W Meadly Jan 1960

Weed Control In Cereals, G R W Meadly

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

WITH seeding almost completed, it is appropriate to review our knowledge of weed control methods in order to undertake any necessary planning.

Although cultural operations provide the first line of attack in the control of weeds in cereals, chemicals are playing a very important and increasing part.

The principles underlying cultural methods, including prevention from seeding and exhausting dormant seed reserves in the soil, are well known and it is intended to devote this article largely to the use of chemicals as herbicides, along with the various implications.


Commercial Vegetable Growing In The Perth Metropolitan Region, L T. Jones Jan 1960

Commercial Vegetable Growing In The Perth Metropolitan Region, L T. Jones

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

MARKET gardening with sprinkler irrigation on deep sandy soils around Perth is really a commercial application of hydroponics or sand culture principles.

Provision of a continuous and adequate supply of nitrogen is the major problem. Peat swamps scattered among the sandy areas have higher natural fertility. However, their common problems are drainage, acidity ("sourness"), salt and various special soil deficiencies. Over-liming of acid swamps can cause new problems.


Control Of The Red-Legged Earth Mite And Lucerne Flea : Treatment Of Seed With Systemic Insecticides, M M H Wallace Jan 1960

Control Of The Red-Legged Earth Mite And Lucerne Flea : Treatment Of Seed With Systemic Insecticides, M M H Wallace

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

THE red-legged earth mite, Halotydeus destructor (Tuck.), and the lucerne flea, Sminthurus viridis (L.), are at present controlled effectively, cheaply and safely by a combined DDT/malathion spray (Jenkins, 1956, 1957) and this continues to be the general recommendation for farmers.

However, this combination has some disadvantages. The DDT in the spray ensures some residual control of the earth mite but has the unfortunate property of toxicity to the bdellid mites which are useful predators of the lucerne flea.

The malathion in the spray assists the DDT to control the earth mite and provides a good, quick kill of the lucerne …


Some Factors Affecting The Baking Quality In Wheat, A R. Egan Jan 1960

Some Factors Affecting The Baking Quality In Wheat, A R. Egan

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

ALTHOUGH between 10 per cent, and 15 per cent, of wheat consumed in Australia is used in feed for domestic animals, the primary usage in home consumption is for bread-making.

Exports, which account for roughly 75 per cent, of the normal Australian crop, are also mainly used in bread-making.
