Water For Agriculture. 3. Watering Plants With Salty Water, Stanley Thomas Smith

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

In Western Australia it is often necessary to use saline water for irrigation and gardening because of the lack of better water.

Two factors influence the results achieved. One is the selection of suitable plants, the other is the way in which the water is used.

Downy Mildew Of Wheat, S C. Chambers

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

The Living Network In Prairie Soils, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

This study treats of our midcontinental soils and of the wonderful network of roots within them of a vegetation which has clothed them for untold centuries. This vegetation has almost vanished so great has been the toll of the tractor-drawn plow, over- grazing and trampling, injudicious use of poisonous sprays, building of highways, and other causes. Virgin prairie and undisturbed soil occur in quantity only in areas where limestone underlies a shallow soil and prevents plowing or in sand so unstable that destroying the vegetation with its binding roots is almost synonymous with losing the soil. The many thousands of …

Classification And Distribution Of The Native Trees Of Utah, Kimball Steward Erdmann

Theses and Dissertations

This study is an attempt to consolidate the information already known about the trees of Utah and to extend our knowledge of these trees. An intensive study was made of the available literature. The tree specimens of the herbaria of the Utah State University, University of Utah, Brigham Young University and the Regional Office of the Forest Service at Ogden were examined. These studies were supplemented with extensive field work in various parts of the state. From this information, keys and descriptions of the genera and species were written and distribution maps for each tree and illustrations of many of …

The Effect Of Fluoride On Glucose Catabolism In Plant Leaves, Cleon W. Ross

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dwarf Fruit Trees, Frank Melville

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

IN this country where most fruits and particularly apples and pears are grown without irrigation, heavy crops and summer stress restrict tree size.

The aim of most growers therefore, has been to grow larger trees and little interest has been shown in trees with dwarfing tendencies.

However, in countries with ideal conditions for growth, trees tend to grow too big and become uneconomic in terms of labour costs.

Citrus Psorosis, H L. Harvey

Organic Manures In Commercial Vegetable Growing, T Wachtel

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

AT one time organic manures provided the only means to return the plant nutrients into the soil, which were removed by cropping.

With the rapid increase of mechanisation, these materials have become very scarce, and their cost extremely high.

It is, therefore, necessary to consider whether the benefits gained from their use are sufficient to warrant their high purchase price, or indeed whether the use of manures is warranted at all.

Journal of the Minnesota Academy of Science

The program was initiated with the support of the Graduate School of the University of Minnesota in May, 1960 through the interest of Dean T. C. Blegen. There are four major objectives: (1) To establish a collection of ripe fruits and seeds to provide a permanent reference file of the entire seed plant flora of the area newly mapped through a grant from the National Science Foundation. (2) To prepare duplicate sets of standard herbarium mounts of material with ripe disseminules, one set for the laboratory at Cedar Creek, the other for the Herbarium of the Department of Botany of …

Establishing Saltland Pastures, C V. Malcolm

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

WITH the approach of winter, thoughts are turning to the seeding season. It will therefore be appropriate to discuss methods of establishing saltland pastures.

This discussion will be restricted to "bluebush," creeping saltbush, and old man saltbush. Seed of these plants is available from local stock firms.

The Granny Smith, Frank Melville

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

MOST of the commercial apples grown throughout the world today have originated as chance seedlings and commercialised by observant nurserymen or fruit growers.

Many Tasmanian varieties were established this way—the Sturma, Democrat and Crofton.

But the seedling which has had the greatest impact on apple growing in Australia is the Granny Smith and its rise to fame is an interesting story.
