Post-Harvest Storage Studies With Selected Fruits, Amrik Singh Dhaliwal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It has been estimated that one-fourth of the fresh fruits harvested are never consumed because of spoilage. This spoilage amounts to many thousands of tons of fruits which are valued annually at several million dollars. Several factors are responsible for the post-harvest spoilage of fruits, namely, pathological, physiological, and mechanical.

Men in the past have used various methods to control pathological spoilage of foods. The recent development of nuclear radiation, antibiotics, fungicides, and packaging films provides new methods for prolonging the shelf-life of many fruits. These may prove important in countries like India where refrigeration facilities are not readily available …

Experiments On The Origin And Nature Of A Zinc Deficiency Of Field Beans On A Portneuf Soil As Determined By The Application Of Zinc 65, Edgar Dale De Remer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In a few instances an agricultural problem lend itself well to research into some of the more basic aspects of a problem as well as to research to determine the exact nature of the problem ad to prescribe a cure. Such a problem was found by the author to exist on a soil of the Twin Falls, Idaho area. Besides making an attempt to ascertain the exact nature of the problem, an experiment was set up in an attempt to understand more about the mechanism responsible for the problem.

Effect Of Sweeteners On The Acceptability Of Selected Processed Fruits, Richard Lee Mclaughlin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1959 Abbott Laboratories estimated (3) that every year 60 million persons go on controlled diets. Of these about 34 million have serious obesity problems, 3 million are diabetics and the rest have disorders that demand strict dietary measures.

The Study Of The Effect Of Various Methods Of Harvesting And Curing On The Color And Viability Of Lima Bean Seed, S. G. Date

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many seedsmen have observed that lima bean seed of a variety like Early Thorogreen, which has green cotyledons, often fades in color during harvesting. This fading of color is known as bleaching. A variety which has green cotyledon and hence green seed, should retain this green color during harvest. Bleached seeds are likely to emerge slowly when planted. Also the final field stand from a planting of bleached seed is likely to be poor.

Estimation Of Optimum Plot Size And Shape For Use In Safflower Yield Trials, Alfred Max Wiedemann

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the big problems encountered in experimental yield trials of field crops is the variation that occurs in yield estimates regardless of how the trial is handled with respect to variety or treatment. This so-called "natural" variation is the result of such factors as heredity, human error, and environment.

A Genetic Investigation Of A Yellow Plant Color Characteristic In Winter Wheat, John Oscar Evans

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objective in wheat hybridization primarily is to obtain new varieties which are of a greater agronomic value than existing varieties. Frequently, however, crosses which obviously will not produce superior commercial types are made and studied in order to obtain genetic information which may be useful to the breeder. This latter phase of breeding, i.e., the accumulation of genetic information, provides the basis for this study.
