Modeling Spring Wheat Production As Influenced By Climate And Irrigation, V. Philip Rasmussen Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A model has been developed that predicts spring wheat grain and dry matter yield. Preliminary tests show very favorable results when predicting grain yield in two different climatic regimes, one being a dryland and another being an irrigated area. The strengths of the model lie in its simplicity, relatively available input data, and low computer processing time cost. Weakness of the model stem from the assumptions that allow its simplicity. The basic assumption in the model is that grain and dry matter yield can be related to the ratio of actual to potential transpiration, computed for each of five phenological …

Studies Of Evaporational Cooling In An Apple Orchard, Stephen W. Zsiray Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the spring, apple orchards are susceptible to freeze damage. Various approaches to orchard protection have been used in the past. Overhead sprinkling for bloom delay has been effective in extending to a later period in the spring the freeze hardiness of apple buds. Thus, protection against a late spring freeze is obtained. Previous research has not been conducted to determine optimum sprinkling times in the spring, the most effective threshold temperature, the amount of water needed to provide adequate bud protection, and the daily length of sprinkling time.

A 2-year investigation was conducted with the objective of obtaining basic …

Adjustment Of Persian Students At Utah State University, Homa Aflatouni

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Social adjustment of Persian students in terms of their social participation with Americans is analyzed by correlation and multiple regression analyses with six independent variables. The six independent variables are: education, attitude, time, English, social class, and religion. The results of correlation and multiple regression analyses support some of the hypotheses. The significant finding is that the level of education the Persian students completed before coming to the United States, their attitudes toward the Americans, and the length of stay in the United States are the most important factors while other variables are much less useful.

An Economic Analysis Of Management Alternatives For Utah Cattle Ranches And Potential Effects On Beef Production, David B. Hewlett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The high feed grain prices of the last few years and the resulting high prices for heavy feeder cattle relative to lightweight feeder calves may provide economic incentives to market cattle from rangelands as yearlings. A majority of the economic studies investigating the profitability of retained ownership of beef calves to sell as yearlings have used a budgeting technique to compare a straight cow-yearling operation retaining all calves, to a straight cow-calf operation selling all calves. In this study linear programming was used to develop an optimum combination of various livestock marketing alternatives for maximizing net ranch income.

Plant Demographic Studies Of Tall Threetip Sagebrush-Grass Vegetation On The Eastern Snake River Plains, Idaho, Kenneth Harold Rea

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It has commonly been assumed that grazing decreases the longevity of plants, however, very few studies address this question. Knowledge of mean age, longevity and other aspects of population dynamics would help improve estimates of productivity and nutrient cycling and aid understanding of range condition and trend. These data would also aid in developing a theory of community organization and control.

As a step toward these ends, pantograph records from twelve 1 m² plots established at the U. S. Sheep Station on the Snake River Plains of southeastern Idaho between 1923 and 1935 were examined. The plots were mapped …
