Iron Deficiency Of Oats In The Lower South West, Edgar Noel Fitzpatrick, R. Sprivulis

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

Oats grown on the acid peaty sands of the West and South Coastal areas of Western Australia develop iron deficiency.

This deficiency can be cured by spraying with iron sulphate. A 2 to 4 per cent, solution can be applied through a low volume spray without damage to the plants. The spray should be repeated when deficiency symptoms reappear.

Growing oats on these soils is not recommended.

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.

Absorption Of C14 Labeled Sucrose By Nectaries, Cecil Wright Lefevre

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the early Eighteenth Century the significance of nectar secretion has been debated. Some have reasoned that it is reabsorbed into the plant and used as energy for the developing embryo while others believe it is a waste product which attracts pollinating insects.

It has been suggested (Brink and Cooper, 1947) that the nutrient supply to developing ovules is a major factor in the development of seed. Also, alfalfa fields pollinated by pollen-collecting bees produce greater seed yields than those pollinated by nectar collectors (Bohart, Nye, and Levin, 1955). It is a well-known fact that more flowers are tripped by …

The Relative Saponin Content Of Alfalfa Varieties In Utah As Measured By Chick Growth Depression, Morris Dean Wilding

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bloat among ruminants is not new to farmers or scientists. One learns from a Roman author's description of this ailment written in 60 A. D. that the symptoms have changed little since that time. Literature also records that the treatments used today for the prevention and relief of bloat are similar to those prescribed by the early Romans (Anonymous 1954).

Root Yields, Sucrose, And Glutamic Acid Content Of Sugar Beets As Influenced By Soil Moisture, Nitrogen Fertilization, Variety, And Harvest Date, Donald G. Woolley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The United States produces about 1.8 million tons of sugar annually. Approximately 75 per cent of this production is derived from sugar beets. The importance of the sugar beet crop in national and world economy is justification for research effort as a means to more economical production.

It is desirable that sugar beet processing be carried out in the most efficient manner. More effective utilization of the sugar beet and its by-products will add stability to the sugar beet industry.

For the past 170 years, since Achard found that sugar could be used for human consumption and that pulp might …

Anther Development In A Male Sterile Line Of Corn, Richard J. Vogl

Bachelors’ Theses

Production of viable pollen through growth and differentiation of the anther appears to depend on the interaction of the tapetum and sporogenous tissue. Very little is known about the nature of this interaction. One way to approach this problem is to study the development of the anther in cases where no viable pollen grains are produced. Highly inbred lines of male sterile corn which are completely pollen sterile have been obtained and are available for study.

The Composition Of The Dwalganup Strain Of Subterranean Clover, A B. Beck

Journal of the Department of Agriculture, Western Australia, Series 3

Subterranean clover is now the major pasture species in Western Australia and according to Elliott (1948) nearly 90 per cent, of the sown pastures of this State have a subterranean-clover base or were originally sown with this species. In spite of its great economic importance, no data have been published showing the chemical composition of the clover growing in this State. In order to fill this gap in our knowledge, series of samples of the Dwalganup strain were collected from three localities. These have been analysed by the Government Chemical Laboratories and the results are presented in this paper.

Elephant Grass, H G. Elliott, L C. Snook

Journal of the Department of Agriculture, Western Australia, Series 3

Elephant Grass, sometimes known as Napier's Fodder, is a hardy, palatable and nutritious plant which under good conditions will give heavy yields. When once established it will remain as a permanent stand so long as it receives good treatment. It grows well in many parts of Western Australia and up to date appears to be free from attack by pests and diseases.

Carotene Content Of Native Nebraska Grasses, I. L. Hathaway, H. P. Davis, F. D. Keim

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The carotene content of twenty-four grasses native to Nebraska were determined at approximately monthly intervals from June to November. While the carotene concentration of most of the grasses was moderately high during the growing season, it declined to a rather low point by late November. With the exception of Switchgrass, Hairy Grama, Little Bluestem and Prairie Dropseed, all of the grasses contained enough carotene to supply the needs of range cattle until late November. However, only eighteen of the grasses still contained enough carotene by the latter part of September to furnish the carotene required by dairy cows. Even as …
