A Study Of Semisterility And Its Lineage Relationships In Translocation Stocks Of Barley, Horace Marr Waddoups

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley (Hordrium sp.) is the most important spring sown cereal crop in Utah, both in acreage and in yield of total digestible nutrients per unit area. It also rates high as a feed crop in the United States. For this reason it is important that varieties are available which are high in yield, high in quality, and disease resistant, along with other desirable characteristics. In order to work toward this end most efficiently, it is first necessary that the genetics of the barley plant be worked out.

The Effect Of Time, Quantity, And Kind Of Irrigation On The Yield Of Sugar Beets, Delos Boyd Archibald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations on factors affecting yield of sugar beets during the past two years at Newton and Garland, Utah, have shown two outstanding facts about irrigating sugar beets. First, the amount of water applied may not be as important as the time at which they receive it. Second, sugar beets should not be made to suffer for water in the early part of their growing season.

These observations suggest the need for further studies on method, time and quantity of irrigation. Further information on the most economical use of irrigation water for sugar beets would be of great value to the …

The Effects Of Fertilizer And Moisture On The Yield Of Sweet Corn, Rex F. Nielson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sweet corn is rapidly becoming an important cash crop in many of the irrigated regions of the intermountain West. The lacome from this crop is relatively small in comparison to that from other major agricultural products; however, sweet corn production has a definite place in the economy of the region.

One of the factors limiting increasing acreage of sweet corn in many areas is low yields. Yields have been increased naterially in recent years with the development of hybrid varieties, superior to the standard varieties previously used. Better cultural practices are improving yields, but much remains to be done in …

The Comparative Value Of Commercial Phosphoric Acid As A Fertilizer, Bruce L. Baird

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The practice of applying fertilizers to the soil by adding the liquid form to the irrigation water is increasing in popularity. There are several advantages maintained for such a method of application. Some of the advantages are:

(A) Ease of application.

(B) No special equipment is required for application.

(C) The fertilizer can be applied at any stage of plant growth without physical disturbance of the plant.

(D) Penetration into the root zone may be greater than the dry fertilizers.

Considerable phosphate fertilizer is used on soils of irrigated regions. If the behavior of liquid phosphoric acid after its incorporation …

Inheritance Studies In Stem Rust Of Wheat, Sayed Bad Shah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wheat is an important food crop of the world, especially in Soviet Russia, U.S.A., China, India and Pakistan. Over one billion bushels of wheat are produced annually in U.S.A. The total area under wheat production in Pakistan during 1947-48 was 10 million acres with an average yield of 12 bushels per acre.

The stem rust disease has been known for along time to be destructive to grain crops, even centuries before the Christian era. Rust is of major importance in both the U.S. and Pakistan. Jethro Tull recorded rust in England in 1725. In 1916, rust was serious over the …

Seed And Forage Production In Four Clonal Lines Of Alfalfa As Influenced By Lygus Infestation, John Keith Noyes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

No other forage crop cultivated in the United States can be used in as many ways as alfalfa. The variety of its uses make it a most useful forage crop.

The distribution of alfalfa is world wide and it plays a leading role in the production of livestock and their products. For general feeding of farm animals, alfalfa is unsurpassed. Used for pasture, it has a high capacity, which leads to large gains in grasing animals. If properly rotated and cared for, it adds nitrogen to the soil in a form that is available to plants and thereby increases crop …
