Effects Of Gamma-Radiation On The Quality And Shelf-Life Of Certain Fruits, Diane Weber Box

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The story of the development of food preservation is as old as the story of man. Cavemen and nomadic tribesmen have little heed to food preservation. They threw away the food left when their hunger was satisfied and searched for more when famished . However, from the time men began to settle down and have permanent homes, the need for some means of retarding food spoilage has been evident.

An Evaluation Of The Salt Tolerance Of Selected Clones Of Agropyron Elongatum, Jordan G. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salt-affected soils make up much of the bottom-lands of the arid and semiarid areas of the western United States and are especially prevalent in irrigated regions. Such soils require special remedial measures, management practices, and salt tolerant crops if they are to have economic value.

The Effect Of Nutrient Levels In Nutrient Cultures On The Translocation Of Foliar Applied Nutrients, David D. Neher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since man first grew crops on calcareous soils he has probably been troubled with what we today call lime-induced chlorosis. This chlorosis has determined whether he grew certain desirable ornamentals or crops or whether he had to substitute others which were less desirable.

Lime-induced chlorosis is spread world wide. It has been reported in the vine and fruit growing regions of Europe, in the chernozem soils of Russia, and many other areas where the rainfall is relatively low and the soil is relatively high in calcium carbonate. In the United States it most frequently occurrs where the average annual rainfall …

A Comparison Of Internal Bicarbonate Of Some Chlorosis-Resistant And Chlorosis-Susceptible Plants, Ralph Barlow Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Iron chlorosis has been a srious problem for many years. This physiological disease has occurred so frequently on calcareous soils that it has been called lime-induced chlorosis by many of the workers. Because the western United States has so many soils of this type, the chlorosis problem has been of primary concern. Untold economic losses have been the result of this physiological disease.

Interveinal yellowing of the leaves along with loss of plant vigor and retarded growth characterize the disease. In severe cases die-back of the terminal growth and eventual death of the plant result. No single factor has been …

Feeding Protein, Phosphorus And Energy Supplements To Beef Cows On Utah Desert Ranges, Robert Hyrum Olsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many of the beef cattle in the Great Basin area are maintained part or all of the year on rangelands. Most of those going on to desert ranges for only part of the year go on during the late fall, winter, and early spring. It is estimated that 50-60 percent of the 600,000 beef cattle grazing on range lands in Utah graze on the one-fourth million acres of desert or semi-desert sometime during the year.

Development And Evaluation Of Laboratory Methods For Determining The Nitrogen Supplying Power Of The Irrigated Soils Of Northern Utah, Jerald Ross Wight

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrogen is the most widely needed and the most widely used of the fertilizer elements. Yet, in spite of the voluminous research work of evaluating the nitrogen status of soils, laboratory tests for the purpose of predicting need of nitrogen fertilizer are not very widely used. In general, laboratory tests for nitrogen supplying power have not given satisfactory results. Methods currently employed by a few laboratories can be classified either as biological or chemical. In the former method, the soil is incubated under optimum conditions and the amount of nitrate released over a given period of time is measured and …

The Influence Of Age On The Cation Exchange Capacity Of Plant Roots, Einard S. Haniuk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A yellowing which develops in some plants growing on naturally calcareous soils is called lime-induced chlorosis. The problem is complex, as indicated by Brown and Holmes (1956) and Porter and Thorne (1955). Species and varieties of plants differ in their iron requirements, susceptibility to lime- induced chlorosis, and inter acting soil f actors which affect iron supply (Thorne et al 1950). Chlorosis of plants does not appear, therefore, to stem from a common causative factor. At least a part of this difference has been found to be associated with the plant roots. Thus, through the use of resistant root stock …

The Effect Of Various Levels Of Bicarbonate, Phosphorus, And Ph On The Translocation Of Iron In Plants, Ronald Conrad Doney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Line-induced chlorosis is a nutritional disease affecting many fruit trees, berries, ornamental shrubs, and flowers in Utah and the western United States. In fact, this disease is of wide distribution on calcareous soils throughout the world. Lime-induced chlorosis has contributed to untold economic loss and has challenged the technical ingenuity of plant and soil scientists throughout the world. As yet the exact cause of chlorosis has not been determined; consequently, no permanent cures have been found.

The first symptoms of this disease are characterized by an interveinal yellowing of younger leaves, with the veins remaining green. In more severe cases …

The Typing Of Staphylococcal Isolates From Turkey Epizootics, William R. Thornley

Biology

Utah has been confronted with the problem of turkey synovitis becoming epizootic in certain areas of the state. This is a crippling disease of turkeys causing considerable loss among birds soon after they are placed on the range. Because much of the expense of brooding and rearing has already been encountered by the growers, the loss is often severe.

The Relative Influence Of The Reaction In Immune Calves On The Sexual And Asexual Stages Of Eimeria Bovis, Richard A. Heckmann

Biology

Coccidiosis has been listed as the third most important parasitic disease in cattle (13). Foster in 1949 estimated that this disease is responsible for an annual loss of ten million dollars in the cattle industry and he believed that the economic loss is at least as great as that caused by coccidiosis in poultry (17). Bovine coccidiosis kills many calves before they are six months old. Only rarely are cattle found free of coccidia (26). According to Gibbons and Baker (18) the mortality has been estimated as high as 29.3 percent in several outbreaks of bovine coccidiosis.

The Effects Of Soil Moisture Condition On Injury To Plants By Hydrogen Fluoride, Orin D. Anderson

Biology

Injury to plants associated with fluorides was first noted about 25 years ago by investigators in Germany. Since that time, and with increasing industrialization of certain areas of the world, this physiological disease has become very Important economically. Fluorides have caused considerable loss to certain crops and to livestock that eat forage containing fluorides in toxic quantities. Johnson (1952) has estimated that the annual loss due to air pollution in the United States total $1,500,000,000 or $10 per capita and that the government and industry are spending about $100,000,000 each year to combat damages. The amount of this damage that …

In the past century there has developed in the fields embraced by physical and biological sciences a considerable knowledge of theoretical and applied information, serving as a versatile tool in combating such problems. Air pollution problems seem to have gained much attention with the rapid development of various industries in major parts of the world. Rural and urban areas adjoining these industrial locales are confronted with the dangerous overall problems of air pollution. Evidently, …

Quality Evaluation Of Deep-Fat Fried Peas, Wattana Sathiraswasti

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dehydration is perhaps the oldest method of preserving fruits and vegetables. However, it is still an important method of preservation. During World War II, efforts were geared to investigate the possibilities of such newer dehydrated foods as powdered eggs, tomatoes, and potato granules. Since then many new products are flooding the market every year. The use of dehydrated products has increased primarily because they usually require less space and have longer shelf life, and at the same time they have much more concentrated nutritive value than fresh, canned, or frozen foods. Hence, they can easily be adopted for military rations. …

The Effect Of Variety, Harvest Time, And Brine Separation On Thiamine, Riboflavin, And Niacin Contents Of Green Lima Beans, Prasertsri Dee-Ananta

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The increasing importance of the lima beans as a substantial cash crop for the growers or farmers and as a quality food for the consumer has initiated many investigations directed towards improving its quality as a vegetable crop. Lima beans are well suited for processing; hence, studies of the quality of different varieties in relation to time of harvest have been made. Host processors are in agreement that the beans attain maximum quality before they are fully mature. After that, the yield and size increase whereas the quality decreases.

The Development Of A Dietary Manual For The Small Hospital, Blanche Z. Madsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An increased amount of emphasis is constantly being placed on the standardization of diets where group feeding is involved. Especially is this true in the hospital where food is an essential part of the medical treatment of the patient. The directing personnel responsible for the diets for any hospital situation where a dietitian is employed, are the doctors who prescribe the diet orders and the dietitian who interprets them.

Morphological, Chemical, Histological, And Sensory Quality Changes In Gamma Irradiated Carrots And Potatoes, Keith Andrew Madsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Through the ages, people have been confronted with the problem of storing food after the harvest season for consumption during the winter months. Foods have been preserved by dehydration, canning, and refrigeration. However, people usually prefer fresh vegetables become unfit for human consumption as a result of sprouting and breakdown in storage.

Some chemicals have been used with various degrees of success in preventing sprouting of certain vegetables. The chemicals were applied as a pre-harvest foliar spray or directly on the tubers or on the roots.

In 1954, a law was passed by the United States Congress authorizing the release …

Absorption Of C14 Labeled Sucrose By Nectaries, Cecil Wright Lefevre

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the early Eighteenth Century the significance of nectar secretion has been debated. Some have reasoned that it is reabsorbed into the plant and used as energy for the developing embryo while others believe it is a waste product which attracts pollinating insects.

It has been suggested (Brink and Cooper, 1947) that the nutrient supply to developing ovules is a major factor in the development of seed. Also, alfalfa fields pollinated by pollen-collecting bees produce greater seed yields than those pollinated by nectar collectors (Bohart, Nye, and Levin, 1955). It is a well-known fact that more flowers are tripped by …

The Effect Of 2 Soil Fertility Levels On 5 Potato Varieties In Relation To Yield, Specific Gravity And Chipping Quality, Gayland D. Robison

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The potato enterprise is important in Utah as it provides a cash crop and also a means of diversifying and intensifying the operations on many irrigated farms. It is of particular value in the sections of the state that have a short growing season where other crops cannot feasibly be produced. The potato chip industry supplies a demand for large quantities of potatoes. The usage by this industry makes it a major factor in potato farming economy.

The making of chips originated over a hundred years ago as the result of an accident. A silver of potato fell into a …

An Evaluation Of The Salt Tolerance Of Particular Varieties, Strains, And Selections Of Three Grasses And Two Legumes, Farrel John Olsen Jr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In arid and semiarid areas in the Western United States, soluble salts tend to accumulate in the soil in amounts harmful to crop production. A considerable portion of this land cannot be reclaimed due to the poor quality of permeability of the soil. Therefore, the wise selection of crops that will produce satisfactory yields on these soils in necessary.

The salt tolerance of many crop plants has been investigated; however, more information is needed on the relative salt tolerance of varieties, strains, and selections. Such information will permit the selection and development of varieties and strains of crop plants which …
