Leaf Growth, Leaf Aging, And Photosynthetic Rate Of Tall Fescue Genotypes, Wallace Wilhelm, C. J. Nelson

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Leaf growth and leaf aging both influence the total amount of CO, fixed by a particular leaf in the canopy during its photosynthetically productive life. Four genotypes of tall fescue (Festuca arundinacea Schreb.) were selected for all combinations of high and low COB exchange rates (CER) and yield. The purpose of this study was to determine CER during aging and leaf growth rates of tall fescue genotypes in growth chambers and in the field on a Mexico silt loam (Udollic Ochraqualfs; fine, montmarillonitic, mesic). Leaf growth of vegetative tillers in controlled environments was continuous throughout the day for all …

Plant Succession Studies On Subalpine Acid Mine Spoils In The Beartooth Mountains, Patricia Lea Howard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Large areas within alpine and subalpine tundra have been by disturbed by mining during this century. The most promising method for retarding deterioration of these areas is revegetation with native species through both seeding and transplants. One natural process of revegetation which occurs on portions of many existing disturbances seems to be the establishment of a few species that expand with time to form matts of plants.

At the McLaren Mine, located at 3000 m elevation in the Beartooth Mountains, Montana, active succession is occurring and is dominated by Carex species. Seed viability and successional patterns studies were conducted on …

Competition And Spacing Patterns Of Shrubs In The Mojave And Sonoran Deserts, Donald Lundahl Phillips

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spacing patterns of shrubs were studied at a series of sites in the Mojave and Sonoran Deserts. There were significant numbers of occurrences of both aggregation and regularity in dispersion of individuals. These may be due to vegetative reproduction or environmental heterogeneity, and competition between plants, respectively. Different size classes of shrubs tended to follow the trend of aggregated → random → regular with increasing size. This suggests the increasing importance of competition as the plants grow. Further evidence of competition between plants was provided by the correlations of plant size with the distance to their neighbors. Root systems were …

Soil And Plant Analysis : A Guide To Fertilizer Usage, Walter Jacob Cox

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

Soil and plant analysis can be used to identify problems in soils, diagnose nutrient deficiencies and as a guide to fertiliser usage.

Soil testing is particularily useful where large amounts of phosphorus and potassium are leached or removed from the paddock in hay or silage.

Actual rates of fertiliser can only be recommended from soil testing and only in conjunction with additional biological and economic information.

Producing 20-Month Old Beef Steers Off Annual Pasture, K D. Greathead, D. J. Barker, W. J. Ryan

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

A recent Mt Barker experiment compared two systems of fodder conservation with continuous grazing, using two types of steers, at three stocking rates. Year-round performance, carcass composition, and resulting costs and returns per hectare were assessed.

Production per hectare was greatest from crossbred steers at the intermediate stocking rate with either type of fodder conservation.

Unialgal Growth Of Anabaena And Dictyosphaerium In Lake Itasca, Charles P. Mason

Journal of the Minnesota Academy of Science

A relatively new field technique was employed to determine the growth of algae in natural waters. Anabaena sp. (Cyanophyta) and Dictyosphaerium sp. (Chlorophyta) were grown in separate membrane filter chambers situated in Lake Itasca and LaSalle Lagoon, a sewage effluent pond. Physical and chemical determinations before and after each two-week experiment were correlated with changes in algal biomass. Wet weight determinations of Anabaena were twice as great in the lake as in the sewage lagoon, while Dictyosphaerium growth was the same in both habitats. Nitrogen (nitrate and nitrite) was 0.09 • 0.2 mg/1 in the lagoon and from less than …

Fisheries Report No 32 - The Wildlife Of The Proposed Wandana Nature Reserve, Near Yuna, Western Australia, A. A. Burbidge, P. J. Fuller, A. Mccusker

Fisheries Research Reports

Following a Cabinet endorsed recommendation by the Environmental Protection Authority in 1976 an area of vacant Crown land (the Wandana Area) north-east of Yuna, Western Australia, was examined during March and September, 1977.

The geology, soils and vegetation of the area are described and annotated lists of mammals, birds, reptiles and amphibians are presented. The area lies near or on the boundary of the South- Western and Eremaean Botanical Provinces and vegetation formations typical of both occur. The vertebrate fauna is a mixture of South-Western and Eyrean species and is especially rich in reptiles, 41 species being recorded. Comparisons between …

Small Mammal Dissemination Of Dwarf Mistletoe Seeds, Daniel Eugene Lemons

Dissertations and Theses

No study has been done in the western United States concerning dispersal of dwarf mistletoe by mammals. At the outset of the study it was determined that the red squirrel, the yellow pine chipmunk (Eutamias amoenus), the northern flying squirrel, and the bushy-tailed wood rat (Neotaoma cinerea), were all potential vectors of seeds. The red squirrel was chosen as the main object of study because it is diurnal and is closely associated with ponderosa pine (Pinus ponderosa), a heavily infected species. The study was undertaken to determine whether small mammals play a significant role in transporting mistletoe seeds to uninfected …

Vascular Vegetation And Flora Of Remnant Forest In The Ohio River Floodplain Between The Great Kanawha And Big Sandy Rivers, West Virginia, John Carl Furry

Theses, Dissertations and Capstones

A total of 246 species of vascular plants representing 75 families were recorded from six physiographically defined forest types in the Ohio River floodplain between the Greet Kanawha end Big Sandy Rivers, West Virginia. Distinct woodlands were those associated with the River flats, River front, bottoms of secondary streams, stream banks, the high floodplain end swamps. Only two species, Acer saccharinum and Platenus occidentalis representing 0.81 percent of the total species encountered, were present in all forest types; 105 species (42.7 percent) were restricted to one forest type. Fifty-five species were new additions to the flora of one or more …

Water And Nitrogen Husbandry For Irrigated Corn In Central South Dakota, Stanley Eugene Papendick

Electronic Theses and Dissertations

The purpose of this study was to evaluate the effects of supplemental water and nitrogen on corn yields. Central South Dakota was chosen as the location for this study because of its existing irrigation and the limited research data available from that part of the state. The objectives were: (1) to determine corn yield response to various water regimes, (2) to determine corn yield response to nitrogen applications, and (3) to determine corn yield response to nitrogen application methods.

Methods Of Analysis Of Yield From Antecedent Winter Water, Charles Gregg Carlson

Electronic Theses and Dissertations

This investigation is an evaluation of methods of analysis of water conserved during off-season periods and evaluation of the effect on the subsequent crop. Energy and water shortages during the midsummer peak irrigation season have forced farmers to consider the possibility of irrigation at times other than peak growth stages as an alternative practice. Dryland farmers are interested in the benefit of water conserving cultural practices such as summer fallow and snow trapping. To evaluate the benefit of these off-season practices, a yield function based upon water availability is necessary. In order to better understand the effects of off-season irrigation …
