Urea Mixture Formulations, H E. Fels Jan 1970

Urea Mixture Formulations, H E. Fels

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

This experiment was done once the experiment above (Urea or Grain Supplements for Stubble) had shown definite but uneconomic responses to a particular mixture of urea, molasses and minerals. The aim was to find whether the response depended on the content of various portions of the mixture, and whether the response to the "shotgun" lick could be explained by the presence of salt, sulphate or cobalt.

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.


High Stocking Rate On Kikuyu Dairy Pasture : Progress Report On Grazing Trials On Kikuyu-Sub. Clover Pasture At Denmark Research Station, F E. Ryan Jan 1969

High Stocking Rate On Kikuyu Dairy Pasture : Progress Report On Grazing Trials On Kikuyu-Sub. Clover Pasture At Denmark Research Station, F E. Ryan

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

KIKUYU is one of the most valuable pasture plants on dairy farms in the South-West of Western Australia.

It combines well with subterranean clover and ryegrass if heavily stocked, and pastures managed in this way can be cut for legume-grass hay in the spring. However, relatively little is known of its carrying capacity or potential for production under grazing.

Superphosphate For Wheatbelt Pastures : Rates Of Application, Walter Jacob Cox Jan 1969

Superphosphate For Wheatbelt Pastures : Rates Of Application, Walter Jacob Cox

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

BECAUSE Western Australian soils are low in phosphorus, frequent applications of superphosphate are required for both crop and pasture production. The recommended rates are determined from the results of field experiments that test different quantities of super and measure the extra yield.

This article discusses the recommended rates of superphosphate in relation to soil type and superphosphate history. Methods of application and time of topdressing are also discussed.

A trial carried out on Denmark Research Station in 1966-67, to obtain information on carrying capacity of a dryland kikuyu-subterranean clover pasture.


Food And Nutritional Needs Of The World Population By 2000 A. D., Sitaram Shankar Kharbas May 1968

Food And Nutritional Needs Of The World Population By 2000 A. D., Sitaram Shankar Kharbas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations were carried out to project the food needs of the world population by 2000 A. D., and to explore the possibilities of meeting these requirements.

About 70 percent of the world population presently living in developing countries do not get adequate diets, and suffer from many diseases of under-nutrition and malnutrition. They are unable to increase food production themselves. People in the developed nations have enough food and their food production is increasing at a rate faster than the rate of growth of population.

Cultivable land is the main source of food for man. The seas can also be …


The Effect Of Oven Temperature, Cooking Method, And Breed On The Tenderness, Juiciness, And Flavor Of Beef, Carma B. Stembridge May 1968

The Effect Of Oven Temperature, Cooking Method, And Breed On The Tenderness, Juiciness, And Flavor Of Beef, Carma B. Stembridge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of oven temperature, dry-roasting, and breed on the eating quality of beef was determined by sensory and objective methods. Two adjacent standing rib and two adjacent chuck roasts of prime, choice, and good grades from animals of Hereford, Shorthorn, and Charolais breeding were dry-roasted. Control roasts (9-12th ribs) were cooked at 325 F. Experimental roasts (6-8th rib and two chucks) were assigned an oven temperature of 325 or 250 F at random. All roasts were allowed to reach ah internal temperature of 155 F as recorded on a potentiometer.

Tenderness, as determined by a Warner-Bratzler shear, was greater …

West Midlands Development : Fertilizers For The West Midlands, Department Of Agriculture, Western Australia

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

FARMING the light lands of the West Midland area would be impossible without fertilisers.

Most light land areas are inherently very low in phosphate and also require nitrogen.

The nitrogen can come from fertiliser for cereal crops, or can be built up by growing appropriate legume pasture plants such as clovers and lupins.

Trials With Urea And Anhydrous Ammonia For Wheat Growing, M G. Mason

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

THE recent subsidy on nitrogenous fertilisers has greatly reduced their price to farmers. This, and farmers' increasing awareness of the benefits of application of nitrogen to cereals, has led to a substantial increase in the use of these fertilisers.


Sources Of Nitrogen For Cereals : Their Characteristics And Costs, M G. Mason Jan 1968

Sources Of Nitrogen For Cereals : Their Characteristics And Costs, M G. Mason

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

Generally similar results may be expected from all the sources of nitrogen available for cereal growing.

The unit nitrogen price and the convenience of use of each fertiliser in the particular situation should be taken into account in deciding which fertiliser to use.

THE first point to consider when deciding which nitrogen fertiliser to use for wheat growing is the effectiveness of the nitrogen source in increasing crop yield. Second, the cost per unit of nitrogen must be considered.

The convenience of using a particular source in a particular situation is also important and greater convenience may offset some cost …


Rates Of Superphosphate For Cereal Grain Production In The Under 20 Inch Rainfall Areas, Walter Jacob Cox Jan 1968

Rates Of Superphosphate For Cereal Grain Production In The Under 20 Inch Rainfall Areas, Walter Jacob Cox

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

EVERY year farmers use large quantities of superphosphate with cereal crops to overcome the inherent phosphate deficiency of West Australian soils.

The increase in the average rate used by farmers reflects the increasing amount of new land being cropped.

Good seasons and favourable economic conditions may also have influenced super rates.


Winter Beef Production Trial : Wongan Hills Research Station, D J. Barker, H. G. Cariss Jan 1968

Winter Beef Production Trial : Wongan Hills Research Station, D J. Barker, H. G. Cariss

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

IN 14-inch rainfall districts most rainfall occurs between May and October. It is d i f f i cult to keep beef animals fattening on summer dry pastures but such areas do have a ready supply of locally grown cereals.

Using these materials as the basis of a supplement it is possible to market prime baby-beef by June-July.

The higher prices obtained for this "winter" beef more than offset the cost of supplementary feed.

Fertilisers For The Wheatbelt, William John Toms Jan 1967

Fertilisers For The Wheatbelt, William John Toms

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

A review of fertiliser research findings and recommendations for fertiliser applications to crops and pastures in the 12 to 15 inch rainfall areas.

NOT long ago, fertiliser to the cereal grower meant only superphosphate for cropping. Today, phosphorus, sulphur, nitrogen, copper, zinc and molybdenum are all important, and the needs of improved pastures must be considered as well as those of cereals.
