Mendelian Inheritance In Wheat Hybrids, J. Leo Mortensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Until the beginning of the present centry the general opinion was that Egypt and Mesopotamia were the earliest homes of cultivated plants. Recent translations of the old Chinese records, however, reveal the fact that many of our cultivated plants were grown by the ancient peoples of China prior to the time of the Egyptians.

Dettweiler (11) (1914) writes: "Today it is admitted--except by a few--that the original home of the primitive European population, the Indo-Germans, is not Asia but northern Europe, that they developed their culture there in the late stone age, and that they then dispersed in their wanderings …

Effect Of Root-Rot Upon Sugar-Beet Seed Production, Louis F. Nuffer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to considerable loss through root-rot of mother beets while in storage during the winter of 1918-1919 the Amalgamated Sugar Company asked advice in regard to planting beets which had decay lesions on them. Would the beets yield seed if planted? How much seed would these beets yield as compared with healthy beets? Would the seed produced be injured by having been grown on decayed beets? It was felt that an experiment carried out with the above questions in view would bring out many facts upon which to base conclusions in answering the questions of the Sugar Company.

A Study Of The Flowering And Fruiting Habits Of The Delicious Apple, Emery R. Ranker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the most disagreeable and at the same time the most unprofitable features of commercial apple production is the tendency of most apple varieties to "take a rest" every other year in order to regain the strength given to the production of a very heavy crop the previous year, and thus be able to repeat the process of heavy production the following year. This process is referred to as "off-year" or alternate bearing. Various causal relationships have been suggested , from time to time, by the different workers in the field but the suggestion now most generally accepted, and …

The Common Intestinal Roundworm Of Swine, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Circulars

The large intestinal roundworm of pigs is a very common parasite, and is probably present in every hog raising district of Nebraska. Up until the last few years the true nature of this parasite was unknown. Little did we realize the actual harm done by this worm; but through the scientific investigations of Stewart, Ransom, and others we now know that this parasite causes heavier losses to the breeder and feeder of swine than any other now common in Nebraska.

Relation Of Environment And Other Factors To Potato Wilt Caused By Fusarium Oxysporum, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present work was undertaken to determine the influence of some environmental factors on the infection and progress of the disease potato wilt. The work has not progressed to the point of determining the exact relation of each of these factors. However, the results thus far obtained are presented here in order to direct attention to the nature and distribution of the disease in relation to the environmental conditions under which certain types of infection take place.

Adequate Diet For The School Child, Susan Z. Wilder

SDSU Extension Circulars

Ease of digestion and adequacy in protein, minerals, and vitamins are absolutely essential for the school child. The results of mistakes in the feedings of school children are not seen as quickly as in the case of younger children. Mistakes in feeding at this age may result in serious diseases conditions later on. The adolescent child probably requires as much or more food than the adult because he is growing rapidly. The three food needs for both children and adults are those to supply building materials for repair and growth, fuel foods for heat and energy, and to take care …

Fruit And Vegetable Budget, Mary A. Dolve

SDSU Extension Circulars

The great need for fruits and vegetables in the diet makes it necessary to give the supply both as to kinds and quantity careful consideration. It takes careful forethought and planning to supply fruits and vegetables adequately for the winter table as well as for summer use. The consideration of this problem must begin with the planning of the garden so the minimum of two fresh vegetables a day during the summer and two canned or stored vegetables during the winter is provided for.
