Distribution And Relationships Of Utah Brome Grasses In Western North America, Jerry B. Anderson

Theses and Dissertations

A considerable amount of study material has beccme available since the revision of the genus in 1900 by Shear, and the revision of the section Bromopsis in 1952 by Wagnon. A number of cytological studies have been done in recent years; and Wagnon's work pointed out the need for a comprehensive study of the entire genus. This study is a taxonomic revision of the Genus Bromus for the State of Utah, and contains illustrations and descriptions of the species; synonomy; distribution maps; and discussions of many of the important aspects of the economics, ecology, and historical treatment. I have recognized …

Fisheries Report No 12 - Results Of A Biological Survey Of A Proposed Wildlife Sanctuary At Dragon Rocks Near Hyden, Western Australia, N. L. Mckenzie, A. A. Burbidge, N. G. Marchant

Fisheries Research Reports

In 1972, three visits were made to an area of vacant crown lam 30 kilometres south-south~east of Hyden, Western Australia.

A preliminary survey was made in April 1972 and following this recommendations were made on the equipment and staff required for a detailed survey of the vegetation and animals.

From the 30th July to the 4th August 1972, a team from the Fauna Research Branch of the Department of Fisheries and Fauna began a detailed fauna survey.

Between the 20th August and the 25th August 1972, the fauna survey was continued am a botanist from the Western Australian Herbarium undertook …

Time Of Planting And Rate Of Seeding On Lupin Yield, G Walton

Experimental Summaries - Plant Research

Of the four time of planting trials twodefinitely showed superiority of earlier seeding (73BA5, 73E6). The two trials in the Southwest (73BR14 and 73MT7) gave highest yields with June sowing compared to May. Three trials (73BR14, 73E6 and 73BA5) appear to have a Variety x Time interaction for plant density, but no definite trend for either Uniharvest or Unicrop although later sowing reduced plant density. Seeding rates in excess of 82 kg/ha gave the highest yields in all trials. The rate of seeding experiments (73BA5 and 73MT7) show that the best crop density for yield (graph) lies between 8 and …

1973 Legume Seed Inoculation, D L. Chatel

Experimental Summaries - Plant Research

Lupin Experiments - Eleven trials were sown during 1973 with the aim of further examining the response of lupins to inoculation on old clover land, new to lupins, and some on new land. The lime pellet and gum slurry methods were compared. The opportunity was also taken to compare a new rhizobia, WU8, with the current commercial inoculant WU425. 1.

The seed x super rate interaction shows the quicker response to super with .higher seeding rates. Low super bank (800 kg/ha) (GRAPH 3) The two sites showed very little response to super applied. On the Eradu sandplain no response to super for either Unicrop or Wheat. On the Watheroo yellow sandplain ( 73M015) the two lupin cultivers and the wheat gave different responses.

Wheat Quality In W.A, J A. Parish

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

Three separate quality classes or categories of wheat are now received by C.B.H. These are a soft biscuit wheat, a hard bread wheat and a mixed grain suitable as a filler wheat in bread-making and for making noodles.

In this article the basis of quality differences between these classes of wheat is described and some of the terms and concepts used in distinguishing between cultivars (varieties) and classes of wheat are discussed.

The Art And Science Of Plant Breeding, John Sylvester Gladstones

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

The first part of this article described the evolution of crop varieties and their improvement by simple selection. This part discusses cross-breeding and the other techniques which underly most modern plant breeding programmes.

The purpose cf crossing is to generate new combinations of varietal characteristics. It does not create anything basically new. All the genetic "ingredients" of a new variety must be present in one or other of the parents.

The Role Of Nematodes In A South Dakota Grassland Ecosystem, James D. Smolik

Electronic Theses and Dissertations

In an attempt to elucidate the role of nematodes in a grassland ecosystem nematode taxa, number and biomass data was gathered over a three year period at the Cottonwood International Biological Program Grassland Biome site in western South Dakota. The effects of grazing intensity, sampling date and sampling depth were studied. Nematicide treatment of range grasses in field and greenhouse studies was also used to evaluate the role of nematodes. Biomass data was used to estimate the intake of plant feeding nematodes. Results obtained demonstrate that soil inhabiting nematodes constitute a significant proportion of the consumer biomass at the Cotton[1]wood …

Extractable Nutrients And Ph Values From Nine Soil Associations Of Arkansas, A. W. Tennille

Journal of the Arkansas Academy of Science

Soil samples from the 0-10-cm and 10-20-cm depths were obtained from nine of the 11 soli associations of Arkansas. Sites sampled had a heavy forest cover and showed no evidence of cultivation. Routine soil tests showed that pH values ranged from a low of 4.38 for the Loessial Hills to 5.83 in the Ozark Highlands. Potassium ranged from 69 to 206 kg/ha. Phosphorus was very low in nearly all sites; the extremes were 9 and 83 kg/ha, but most values were less than 30 kg/ha. Calcium ranged from 122 to 1,523 kg/ha. The data indicate that when woodland areas are …

Farm Operations Management, H E. Fels, A. W. Hogstrom

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

The main defence of Australian farmers against the cost-price squeeze has been to increase productivity. The tendency is to run more and more stock per man and to grow more crop per man.

Some farmers run unusually large numbers of animal units per man-year.

The operations of 16 such farmers over one year were examined to find out whether it had been profitable for them to reduce labour inputs to such an extent.
