Estimating Agricultural Production Functions From Experimental Data For Different Crops In Relation To Irrigation, Fertilization And Soil Management In Northern Utah, Subramaniuam Swami Nathan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Estimates of agricultural production functions from experimental data for four different crops in relation to six variable inputs are calculated by this study. There are four basic sections in the study. The first section covers the review of production function concepts and the procedures and problems that specifically pertain to this study. Also the importance of joint economic-agronomic research efforts, methodologies and applications of agricultural production functions are cited.

The second section includes the presentation data and postulated functional relationships in estimating production functions. Model building programs are used in developing three dimensional figures, which aid in the selection of …

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 …

The Response Of Barley To Soil Moisture Tension And Fertilization, Mahmood Agah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley is one of the important crops in many of the irrigated regions of the world. It is an important crop in Iran for both human consumption and livestock feed. In the United States and Europe it is used for livestock feed and beverages.

The income from this crop is moderate in comparison to that from other major agricultural products.

Barley production has a definite place in the economy of the region, because it requires only a small amount of care. It can be readily grown on poor lands. One of the factors contributing to the increased acreage of barley …

The Yield And Thiamine, Riboflavin And Niacin Content Of Alfalfa Hay As Related To Fertilizer Treatment Of Soil, Rasik L. Pathak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa has long been recognized as an outstanding hay plant in terms of both yield and feeding value. It is high in digestible protein, minerals, and vitamins. Because of its long life it can be economically produced. It is of exceptional value in maintaining soil fertility by helping to control erosion, by improving the physical condition of the soil, and by accumulating large amounts of nitrogen.

The great importance of alfalfa growing in the United States is attested by its rapid and continued expansion. It is one of the most important forage crops and is grown on a greater acreage …
