Seed Response Under Snow On A Subalpine Range In Central Utah, Alvin T. Bleak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The response of grass, forb, and shrub seeds to the subalpine environment during the fall and under winter snow and under laboratory conditions at 20/28 C was observed for 3 consecutive years at an elevation of about 3000m on the Wasatch Plateau in central Utah.

Seeds in nylon sleeves were planted under 2 cm of soil before snowfall. Under snow plantings were made directly on the soil surface and under 2 cm of soil. The seeds planted before snowfall were removed each year on four occasions: when under snow plantings were made, after snow depth exceeded 130 cm (deep snow), …

Weed Control Research Pays Dividends, G R W Meadly

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

On my bookshelf is a handbook entitled "War on Weeds" or "How to Double our Food Supply."

In many of these countries experiments have been made to ascertain as far as possible the exact damage done by weeds to crops.

Result: In all the experiments, whether made in England or abroad, the mean loss was over 50 per cent.

The level of loss is equally true today, but the methods at our disposal for handling weeds have improved tremendously.

The Western Australian Herbarium, Department Of Agriculture, Western Australia

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

The new Western Australian Herbarium building opened on March 5, 1970, provides for the first time, ideal storage conditions for the State's priceless collection of plants, and adequate facilities for botanists to study them.

The unique character of Western Australia's flora has attracted world-wide interest and the State needed a single herbarium recognised by the herbaria of the world.

Phosphate Applications Affect The Coumestrol Level Of Medics, T Marshall, R. J. Parkin

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

Western Australia has a million acres of medics including various cultivars of barrel medic, Medicago truncatula, and strand medic, M. littoralis. Both species contain coumestrol, a chemical thought to have caused delayed conception and reduced twinning rates among grazing ewes in New Zealand.

No infertility has been reported among ewes grazing medic pastures in Western Australia, but coumestrol levels in both species have often been high enough to suggest the possibility of oestrogenic responses among sheep grazing them.

Fertiliser Recommendations For Citrus : Detailed Fertilizer Programmes For Citrus Growers, N H. Shorter, J. E. L. Cripps

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

CITRUS growers should adopt a well balanced fertiliser programme to safeguard tree health, cropping and fruit quality. While moderate dressings are a wise insurance in most situations the rates required vary with tree age and soil type.

The recommendations are given in detail in the tables in this article.
