Recommended Crop Varieties, Department Of Agriculture, Western Australia

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

RESULTS of variety trials carried out in 1968 by the Department of Agriculture were considered by the State Wheat Advisory Committee and the State Coarse Grains Advisory Committee in making recommendations on leading varieties of wheat, oats and barley.

Details of the recommendations are set out below.

Recommendations on linseed varieties have been included in view of the growing significance of the industry and representations from farmers for consideration of this crop along with the cereals.

The Effect Of Nitrogen Rate And Method Of Sucker Control On Dry Matter Accumulation In Different Plant Parts Of Burley 21 Tobacco, J. L. Sims, W. O. Atkinson

Agronomy Notes

Earlier research has shown that higher leaf yields of burley tobacco result from topping and controlling sucker (axillary bud) growth. Suckering practices which provide the greatest degree of sucker control generally result in highest leaf yields . Chemically suckering with maleic hydrazide (MH-30) and other chemicals provides for a higher degree of control than most hand sucker ing practices although hand sucker ing at frequent intervals may produce leaf yields comparable to those from use of maleic hydrazide. High leaf yields resulting from a high degree of sucker control has been attributed to the elimination of the use of photosynthate …

Summary Of Fertilizer Use And Estimated Use Of Plant Nutrients On Tobacco, Corn, Hay And Pastures In Kentucky, Kenneth L. Wells

Agronomy Notes

Nearly 650, 000 tons of fertilizer were used by Kentucky farmers during the first half of 1969. Plant food content (N+P₂O₅ + K₂O) was 38%, or nearly 247,000 tons. Slightly over half (58%) was sold in bagged, one-third (33%) in bulk, and 8% in fluid form. Mixtures made up 70% of the total tonnage, and materials made up 30%. The statistics tabulated below show a more detailed breakdown of the fertilizer tonnage used.

The Capability Of The Utah State University Drainage Farm As An Irrigation And Drainage Demonstration Project, Mario Perez

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

There are in Cache County 20,000 acres of poorly drained land similar in many respects to the other wet lands of Utah, estimated to total a half million acres, which are mostly natural meadows. In order to turn those lands more productive either for forage or other crops, adequate management practices must be developed regarding control of the surface water, leaching, reduction of artesian pressure, and improved water application techniques.

Studies carried out at the Utah State University Drainage Farm, west of Logan, Utah, which is representative of those poorly drained lands, have already shown successful ways for these areas …

Grain Sorghum Performance, C. R. Tutt, J. F. Shane

Agronomy Notes

Twenty-five grain sorghum hybrids and one variety planted May 22 were evaluated at the Western Kentucky Substation at Princeton for yield, plant height, date headed, head type and moisture. They were also evaluated at Lexington for bird damage and at the Robinson Substation for MDM.

Soil Surveys In Kentucky, Harry Hudson Bailey, Robert L. Blevins

Agronomy Notes

Soil surveys are a scientific inventory of the soil and land resources of an area. They locate the different kinds of soils and provide information as to their physical and chemical properties. The surveys also contain tables and charts showing the use of the soils for agriculture, engineering, community development, recreational areas, woodland, and wildlife.

Today there is some type of soil survey activity in every county. The University has cooperative soil survey arrangements with the USDA Soil Conservation Service and the U. S. Forest Service.

Irrigating Corn On Well-Drained, Limestone-Derived Soils, John L. Ragland, J. C. Redman

Agronomy Notes

In trying to determine if it would pay Kentucky farmers to irrigate corn, one of the most important steps is to ascertain the long-time average yield increases to be expected from supplemental irrigation. The yield data reported below are the results of an experiment applicable for a fairly large group of soils occurring in Kentucky.

Lupins In Western Australia. 1. Species And Varieties, John Sylvester Gladstones

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

First in a series of articles on the varieties, cultivation and uses of lupins in Western Australia.

Lupins are ideally suited to the climate and soils of many districts of Western Australia and their cultivation here dates from the early years of the century.

However, although there were some 500,000 acres of lupins growing in the State in 1968, their cultivation in recent years has been largely limited to infertile sandplain soils where other legumes usually fail.

Nitrogen Fertiliser Survey, Department Of Agriculture, Western Australia

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

THE DECEMBER, 1968 issue of the "Journal of Agriculture" included, as part of an article on the economics of nitrogen fertiliser use, a lift-out section for farmers to complete and return to the Journal.

In the lift-out, farmers were asked to calculate their fertiliser costs and answer a series of questions about the use of nitrogen on their farms.

Simple Treatment Will Protect Farm-Stored Grain, Department Of Agriculture, Western Australia

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

WITH unusually large quantities of grain likely to be stored on farms this season, 1970 will be an important year for the control of pests in stored grain.

Infested grain from farms is responsible for almost all outbreaks of infestation in bulk storages, leading to costly treatment by the grain handling authority. Effective control on the farm would eliminate most of this.

Continuous Cropping Trials, M G. Mason

Experimental Summaries - Plant Research

The aims of the trials at Binnu, Chapman, Wongan Hills, Avondale and Merredin were:

1. To determine whether the application of nitgrogen and fertilisers can maintain yields under a "continuous cropping" system
2. To compare the merits of three sources of nitrogen for this purpose.
3. To determine the maintenance dressing of superphosphate under this system and the need for supplementary fertilisers.

Trial 61A2
There have been no great problems with this trial. for a number of years the plots have required chemical spraying to control wild oats which had built up. In 1968 and 1969 some plots were soil sampled to determine …

A Comparison Of Methods Of Urea Application At Ajana, M G. Mason, R. J. Parkin, H. Patrick

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

Compared with urea application separate from the seed, urea mixed with wheat seed delayed and reduced wheat germination, and reduced wheat yields, especially at high rates of urea.

Yields were higher where the urea was topdressed immediately before seeding than where it was top-dressed either immediately after, or two weeks after seeding.

Recommended Cereal Varieties : 1969, H M. Fisher, J. T. Reeves, J. A. Parish

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

Cereal varieties widely recommended for growing in 1969 are Gamenya and Falcon wheats, Dampier and Beecher barleys and Swan oats.

Other varieties include the new wheat Darkan, which is recommended only for the higher rainfall areas, the rust resistant wheats Mengavi and Gamut, and Irwin oats for late sowing in northeastern districts.

Pasture Establishment In The Wheatbelt, M L. Poole

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

The value of legume based wheatbelt pastures is so great that considerable care is warranted during their establishment. Without such care patchy establishment or even complete failure is likely to occur.

IN THE WHEATBELT too many farmers still put less effort into their seeding of pasture species than their seeding of crops.

This may be because both compete for the farmer's time in the busy seeding period and it is the cereal crop which possesses the obvious cash value.

However, the total value of a good pasture has to be assessed over a period of several years because of its …

Pasture Improvement In South Western Australia, J W. Malcolm

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

"There is no doubt that Australia's enhanced prosperity in the last 30 years has been dependent in no small measure on the use of legume-based pastures." E. M. Hutron, June, 1968. *

THE LAST 30 years have seen an increased interest in pasture improvement which has transformed much of Western Australia. Large areas have been sown to new and improved pasture species—as a result productivity of both livestock and cereal enterprises has risen.

Weed Control In Linseed, J G. Paterson

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

In 1967, almost 7,000 acres of linseed were planted in Western Australia. The area increased to more than 25,000 acres in 1968 and it is expected that some 40,000 to 50,000 acres will be planted in 1969.

FOR MANY years linseed has been a comparatively unimportant crop, recently been highlighted both as a "cleaning" and as a "cash" crop. Its value has

Weed Control In Pastures : A Practical Approach For Sheep Areas, Geoffrey A. Pearce

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

IN the past, chemical treatments for the control of weeds in pastures have been costly and severe on pasture, and have had to be repeated over a number of years. The method outlined in this article overcomes nearly all these disadvantages.

The Control Of Weeds In Cereals, Geoffrey A. Pearce

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

PRACTICALLY all broadleaved weeds found in cereals can now be killed with herbicides and with most, the farmer has a choice of chemicals.

Two more new products are now available and these have several advantages over other herbicides.

Chemical Ploughing, Geoffrey A. Pearce

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

PROGRESS in the field of chemical weed control has been spectacular in recent years. One field that is attracting interest is the idea of replacing cultivation with chemical sprays.

Linseed Production Survey : Esperance, 1968, R J. Guyton

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

A SURVEY conducted after the 1967 linseed season found that although most farmers understood the requirements of linseed growing there were several crop failures. These were associated with time of planting, soil type and insect control measures.

The Esperance district office of the Department of Agriculture conducted a second survey during December, 1968 and January, 1969

Oat Diseases In Western Australia, W R. Tweedie, W. A. Shipton

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

OVER ONE MILLION acres of oats are grown yearly in this State, making the crop next in importance to wheat.

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

WREN WHEAT, the subject of current controversy in the Eastern States, has been tested in trials in Western Australia and the results have indicated that it is not likely to yield well in this State.

Costs Of Grain Storage On Farms, P J. Hackett

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

GRAIN storage on farms has been commonly practised for intensive livestock production, for feed reserves, for seed purposes, and more recently to store excess grain.

For most of these purposes permanent storage facilities are required.

Lupins In Western Australia. 2. Cultivation Methods, John Sylvester Gladstones

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

While lupins are by and large plants of lighter and less fertile soils, important differences exist among them in their soil preferences.

There may also be some differences in climatic requirements. Present knowledge of these differences is summarized in the Table below.

Linseed : An Alternative Crop For The South Coast, R J. Doyle, R. J. Guyton

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

IN the over-17 inch rainfall zone of the south coast region of Western Australia animal production is the main farm enterprise.

Although farmers in the main cereal growing regions of W.A. crop about one-third of their cleared land each year, farmers in the south have been reluctant to crop more than about 12 per cent, of their cleared area.

Deferred Grazing Improves Soft Spinifex Association, H Suijdendorp

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

THE Pastoral region in Western Australia where Triodia pungens (soft spinifex) makes up most of the vegetation, covers an area of about 17,000 square miles in the Forrest and De Grey pastoral areas.

On the deeper granitic sands in much of the region, plant associations revert to a pure stand of soft spinifex after about five or six years' grazing. It is common practice to burn at this stage, to encourage the re-establishment of other species and the production of palatable spinifex regrowth.

Lupins In Western Australia. 3. Cultivation Methods Continued, John Sylvester Gladstones

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

THE characteristics of the lupin varieties grown in Western Australia were described in the first two articles of the series (Journal of Agriculture, August and September, 1969), together with recommendations for growing bitter sandplain lupins.

This article gives general recommendations for growing grain lupins, and discusses the main diseases and pests of lupins in Western Australia and their control.

The Long Term Effects Of Frequent Cropping, Stanley Thomas Smith

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

AGRICULTURALLY speaking, few Western Australian soils are more than 50 years old. We have the responsibility of preserving them for farming—not for one man's lifetime, but for centuries.

The aim of this article is to demonstrate that cropping and cultural practices do have some effects on the soil, and that these effects should be considered when choosing a farm rotation.

Agronomy Of Low Alkaloid Lupins - Preliminary Investigations, C M. Francis

Experimental Summaries - Plant Research

Although the value of leguminous crops in the pattern of Western Australia's agriculture has been recognised for a number of years (Gladstones (1968))*, they have received comparatively little scientific attention. Whilst one such crop, the "sweet" lupin, has occasionally produced highly profitable yields, there is nevertheless a high incidence of near failures which may to a large degree be logically attributed to lack of knowledge of the basic agronomy of the crop. As a preliminary to more extensive trials at a large number of locations, it was proposed to study the effect of some basic agronomic practices (and of the …
