Soil Nitrate, Total Nitrogen And Organic Matter In Relation To Dry-Farming, Krishnappa Ramaiah

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Dry farming has been defined as production of useful crops, without irrigation, on lands that receive an annual precipitation of 20 inches or less. In some regions the term dry farming is applied to farming without irrigation under annual precipitation of 30 inches or less. Although there is no sharp demarkation between dry farming and humid farming, the term dry farming always means farming under difficulties due to limited annual rainfall.

Inheritance Of 16 Barley Characters And Their Linkage Relationships, Tejpal Singh Gill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The assignment of genetic factors to definite loci in the hereditary mechanism has been a great step in the progress of biology. Of the cereal crops, barley (Hordeum sp.), a crop of economic importance, offers a superior opportunity for genetic studies. Its adaptation to wide varieties of conditions, with a wealth of easily differentiated characters and only seven pairs of chromosomes, the barley plant provides excellent material for linkage studies.

Although there is a vast amount of literature dealing with inheritance in barley, yet knowledge of the subject is still very limited. The mode of inheritance of about one hundred …

Use Of Dk Cheese Starter In Manufacture Of Commercial Cheddar Cheese, Carl Anthon Ernstrom

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several months' curing time is needed to give cheddar cheese the desirable flavor demanded by the market. The exact length of time required for curing depends upon the flavor intensity desired, but the curing process is always costly and time-consuming.

The practice of making cheddar cheese from pasteurized milk is now common throughout the industry. Many progressive cheese factories are pasteurizing their milk and enjoying the consequent benefits from a higher quality product. Although pasteurization has eliminated many of the quality problems in cheesemaking, it has resulted in even slower curing cheese.

Much of the cheese research now being carried …

Effects Of Aureomycin In Milk Used For The Manufacture Of Cheese, James A. Banghart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Importance of project:

In recent years many antibiotics have come to the foreground as a treatment for mastitis. Aureomycin is one of the more recent antibiotics that has been used for this purpose.

Aureomycin has been reported to be successful in curing some types of mastitis, but milk produced by cows that have been treated with Aureomycin does not act normal in the cheese manufacturing process. The most noticeable effect in milk from cows treated with Aureomycin has been slow or complete cessation of acid production by bacteria in cultured dairy products; this has been especially true in the cheese …

Application Of Pheasant Census Methods In Cache County, Utah, Gordon L. Zorb

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An inventory of the stock on hand is a basic step in management. This is true whether the field be business, land, or wildlife management. It is a marginal business man who ignores the basic step of inventory. In the history of wildlife management, however, it has not been unusual to find the cart before the horse. This is not to say that the wildlife manager is, or has been, marginal. His business was inherited ready-made, but often in a bankrupt condition. The problems were there, but not the background of records, techniques, or methodology to cope with them. Often …

Age And Growth Of The Green Sunfish Lepomis Cyanellus Rafinesque In Northern Utah, Young E. Wright

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The green sunfish Lepomis cyanellus Rafinesque is a member of the sunfish family Centrarchidae. Curtis (1949) states that all members of the sunfish family are native only to North America, and are primarily warm-water fish. According to Jordan and Evermann (1934) the green sun-fish is generally abundant in all suitable waters from central Ohio and Indiana to the Rio Grande. Forbes and Richardson (1920) give the general distribution of the green sunfish to be from the Great Lakes to Mexico, the Mississippi Valley, and everywhere in small sluggish streams except east of the Alleghanies and in Canada. The green sunfish …

Reactions Of The Rocky Mountain Muskrat Ondtra Zibethica Osoyoosensis (Lord) To Drought Conditions At Ogden Bay Bird Refuge, Utah, Edward V. Saunders

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Perhaps no mammal on the North American Continent has received more attention in the literature than the muskrat (Ondatra spp.), but little of this material pertains to the reactions of muskrat populations to drought conditions. The author was unable to find any literature containing information on the reactions of the Rocky Mountain muskrat Ondatra zibethica osoyoosensis (Lord) to drought conditions in Utah. This information is of vital importance in formulating muskrat management programs in the State.

On many farms the muskrat population represents the greatest cash value of any kind of wildlife, and they utilize swamp areas and marshlands …

The relationship of standard length to weight is described by the formula W = 0.000022 L …

The Food Of Pond Fish In Northern Utah, Robert L. Eberhardt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A series of ponds in northern Utah supplied mainly by artesian water was poisoned with rotenone during 1949-50. Four hundred and seventy-three fish were obtained for a food habits study, and of these fish, 423, or 89 percent, had food in their stomachs. The species studied were largemouth bass, green sunfish, common bluegill, and black bullhead. Largemouth bass had the widest variety of diet throughout the year but also had the highest percentage of empty stomachs. Green sunfish and black bullhead had the least diverse food habits. Twenty-nine different food items were recorded; those used most commonly were green sunfish, …

Some Relationships Of Potassium To Lime-Induced Chlorosis, Wilford H. Robinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chlorosis, the yellowing of plant leaves, results from reduced synthesis of chlorophyll. It is caused by a deficiency or an unbalance of essential nutrient elements. The amount and pattern of yellowing varies with the cause and severity of the disturbance. Chlorosis results in reduced vigor of the affected plants and a corresponding loss in quantity and quality of the product grown. In severe cases chlorosis may lead to the eventual death of the plant.

Fertilizer Trials On Dryland Winter Wheat, I. G. Sampson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wheat is one of the major crops of Utah and for more than 50 years farmers have been raising wheat on the dry lands of the state. The system they use is known as the alternate cropping or crop-follow system and consists of one year of crop alternating with one year of clean cultivation known as fallow.

Wheat removes a considerable amount of the natural plant food elements from the soil each year. This is especially true of nitrogen. According to Bracken and Greaves (9) the original low supply of nitrogen in most Utah soils together with the depleting effects …

Studies Of The Dodder Transmission Of The Western-X Virus From Peach To Herbaceous Plants, Lewis G. Weathers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Western-X disease is considered to be the most serious and destructive virus disease affecting peaches in the northwestern United States. The virus causing this disease in peach also infects chokecherries and most varieties of sweet and sour cherries. There is also evidence (13) that certain varieties of plums and apricots are susceptible. No information now exists to indicate that the virus occurs in plants outside of the genus Prunus. It is found that woody plants such as stone fruit trees are not particularly favorable plants for studying the virus. All attempts to isolate the western-X virus from woody tissue …

A Genetic Study Of Complementary Genes For Purple Lemma, Palea, And Pericarp In Barley (Hordeum Vulgare L.), John William Thieret

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In certain plants the expression of various characters depends upon the presence of two pairs of complementary genes in the individual. The striking feature of this situation is that two plants, phenotypically alike or similar but of different and appropriate genetic constitution, may, after crossing, produce progeny which are phenotypically different from either parent.

The Inheritance Of Resistance To Verticillium Wilt In Tomato, Lester Schaible

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Opercular Bone As An Indicator Of Age And Growth Of The Carp Cyprinus Carpio Linnaeus, William J. Mcconell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As part of an investigation of the non-game fish resources of Utah, a study of the age and growth rate of the carp was instituted. A preliminary investigation indicated that the opercular method was superior to several other methods of determining age and growth in the carp. Age and growth were calculated from the opercular bones of 330 carp collected at Ogden Bay Refuge in 1950-51. Distances to annuli were measured directly. The relationship between the posterior radius of the opercular bone and the standard length of the carp was curvilinear. Past growth was calculated with a logarithmic nomograph. Expected …

An Annotated Bibliography Of North American Upper Cretaceous Corals, 1785-1950, Bob F. Perkins

Fondren Science Series

Although more than one hundred species of corals have been described from the Upper Cretaceous formations of North America, there has been no attempt, to date, to compile a bibliographic index of the species. The author feels that such an index would be useful to paleontologists in future identifications. The following bibliography includes a list, with annotations, of all available literature on North American corals of Upper Cretaceous age; a catalogue of genera and species; and a plate showing the distribution of species.

The Desert Shall Blossom As The Rose, D. Wynne Thorne

Faculty Honor Lectures

IRRIGATION AGRICULTURE has not received attention commensurate with its significance in either ancient or modem times. Although most ancient civilizations depended on irrigation for their very existence, one can consult volume after volume of history only to find irrigation scarcely mentioned. To the agricultural specialist the great challenge and the strength and weakness of irrigation agriculture is not in constructing Boulder Dams nor in planning winding canals and syphons to carry water from the Columbia River to California. The critical point is on the farms where water is applied to the soil and crops are harvested. There the real battles …

Hindeastraea Discoidea White From The Eagle Ford Shale, Dallas County, Texas, Bob F. Perkins

Fondren Science Series

In 1888 Charles White made Hindeastraea discoidea the type of a new genus of Cretaceous coral. The type specimen was reported to have been collected from the Ripley (Navarro) formation near Terrell, Kaufman County, Texas. The next year Robert T. Hill reported what he considered to be the same species in the shales at Eagle Ford, Dallas County, Texas. The note was not accompanied by a description, and the corals were referred incorrectly to the genus lsastrea. Although the occurrence of these corals in the Eagle Ford has been known to many collectors other than Hill, there has been no …
