A Study Of The Environmental Conditions Influencing The Development Of Stem Rust In The Absence Of An Alternate Host. I. The Viability Of The Urediniospores Of Puccinia Graminis Tritici Form Iii, George L. Peltier

Nebraska Agricultural Experiment Station: Historical Research Bulletins

No exact data are at hand regarding the influence of temperature and relative humidity on the viability of the urediniospores of stem rust under controlled conditions. 1. The influence of relative humidity on the viability of the urediniospores of Puccinia graminis tritici Form III is very pronounced and closely associated with temperature. 2. At high relative humidities, depending somewhat on the temperature, the percentage of germination is low and the period over which the spores are viable is very short. 3. The same relation exists at the low relative humidities except that it is not so pronounced and is more …

Bulletin No. 181 - Duty-Of-Water Investigations On Coal Creek, Utah, Arthur Fife

UAES Bulletins

Coal Creek flows from the west slope of the part of the Wasatch Mountain range which is located in the southeast part of Iron County, Utah. Its drainage area is almost 100 square miles.

Seasonal and daily stream-flow fluctuations are very pronounced. During the high water of spring the flow has reached more than 600 second-feet. At the time of high water, the daily fluctuations are the greatest. During the low water season in July and August, the flow has dropped as low as 12 second-feet since 1917, when accurate records were first kept; and, from the accounts of early …

Farm Record Keeping And The Application Of Business Principles To Farming, M. R. Benedict, H. D. Mccullough

SDSU Extension Circulars

How to make his farm return enough profit for a wholesome, worth while living and provide for moderate saving is the problem confronting every farmer to-day. Every farm family wants a comfortable home, schooling for the children, electric lights, running water, and the other comforts of life, but usually these things cannot be had unless the farm is made to pay as a business proposition. Farming is not and never has been a means of getting rich quickly or easily. It is a substantial and necessary occupation offering many advantages. On the other hand, it seldom has paid the farmer …

Studies Of Immunity Against Hemorrhagic Septicemia, L. Van Es, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Research Bulletins

As one of the phases of our inquiry an effort was made to acquire some general knowledge regarding the immunizing value (1) of sera prepared with the aid of Bacillus bipolaris septicus procured from cattle and swine or (2) of those alleged to be of service in the control or treatment of hemorrhagic septicemia in the species mentioned. The experiments reported in this publication were almost exclusively made with sera purchased from dealers in biologic products.

July Garden Club Activities, A. L. Ford

SDSU Extension Circulars

This is the month that you will have to do the most studying on how to keep every square yard of your garden working for you. Many rows of your earlier crops including peas, lettuce, radish, onions, and spinach will have born their crop and be lying idle by this time. The question now is, what shall I put in those vacant rows? Here are some suggestions that may help you.

Bulletin No. 182 - The Net Duty Of Water In Sevier Valley, Orson W. Israelsen, Luther M. Winsor

UAES Bulletins

The Sevier River is one of the most important sources of irrigation water in Utah. It rises in two main branches. The south fork rises in Kane County and flows almost due north to Junction in Piute County, where it joins the east fork, which rises partly in Garfield County and partly in Sevier County. The Garfield County branch of the east fork flows north, and the Sevier County Branch flows south to Coyote where the two tributaries join and flow westward into Junction. From Junction, the river flows northward past Marysvale, Sevier, Richfield, Salina, Gunnison, and Mills, where it …

The County Agent's Handbook, I. B. Johnson

SDSU Extension Circulars

In the daily work of the county agricultural agent, the agricultural extension worker, the farmer, or anyone interested in agriculture, questions arise, whose answers involve much detailed information. Workers have frequently realized the value of a ready, pocket-sized reference from which such information might be obtained. It is hoped that this handbook may fulfill such a requirement. The material enclosed is of special application to the agricultural conditions of South Dakota, yet so much of it is of general application that the handbook will be found useful by any agricultural worker. The loose leaf plan enables anyone to add whatever …

A Synopsis Of The Scarabaeidae Of Nebraska (Coleoptera), R. W. Dawson

University Studies (University of Nebraska) (1888–1984)

Several years ago the writer undertook a study of the "June-bug" family (Scarabaeidae) for the state of Nebraska. The object of the study was two fold: First to determine the number and status of our species in this large and economically important family, and second to present a taxonomic review which would enable the beginning student, or interested amateur, to readily name with reasonable certainty any species which he might encounter in the state.

In the following pages 40 genera and 162 species are tabulated, and notes given on the abundance, seasonal and geographical distribution of the species within the …

A Synopsis Of The Syrphidae Of Nebraska With Descriptions Of New Species From Nebraska And Colorado, Everett E. Wehr

University Studies (University of Nebraska) (1888–1984)

In June, 1907, Mr. Paul R. Jones published in the Journal of the New York Entomological Society "A Preliminary List of Nebraska Syrphidae with Descriptions of New Species.'" At that time there was available only a comparatively small collection of Syrphid flies, but apparently it contained a fairly good representation of the species found in the state. Subsequent collectors have contributed a considerable amount of new material from the state in which there are twelve additional species, two of which are· new. With these additions, the Nebraska list is increased to ninety species.

At the present time the classification of …

Garden Pests And Diseases, A. L. Ford

SDSU Extension Circulars

There are hundreds of species of insects and hundreds of different plant diseases that attack our garden crops here in South Dakota. They are always in danger from these. This being the case there is but one thing for each garden club member to do and that is to learn the best way to get rid of the pest before the pest comes. If you’ll do that you will always be ready and the boy or girl who is ready in a case like this is going to win out.

Insect Pests And Plant Diseases Of The Strawberry Bed, A. L. Ford

SDSU Extension Circulars

Insect pests and plant disease cause a continual loss in many strawberry beds. As a rule this loss is disregarded by the average grower who believes that there is nothing practical that can be done. We maintain that for an individual to grow strawberries efficiently, he must give this loss caused by insect pests and plant disease due consideration.

Variations In Cytology And Gross Morphology Of Taraxacum Ii. Senescence, Rejuvenescence, And Leaf Variation In Taraxacum, Paul B. Sears

Papers in Ecology

The variability of Taraxacum has frequently been recorded in botanical literature without receiving much elucidation. It is less often an object of investigation than of conjecture and discussion. A few botanists have studied the effect of environmental factors upon Taraxacum, but their results have not cleared away taxonomic difficulties. Systematic botanists have either looked upon the variations in this genus as fluctuations or slight mutations, and then proceeded to lump or split as judgment might dictate. That life history exerts a profound influence upon form seems generally to have escaped attention.

Anthocyan Pigments, Paul B. Sears

Papers in Ecology

Noack has found rhamnose-free flavonol diglucosides to be much more abundant in green leaves than has generally been supposed. In such leaves as he studied he was able to establish the existence of flavonol-anthocyan in couples of similar glucosidal nature, but secured no evidence of aromatic nucleus composition in such cases. He suggests that these couples function as a reduction mechanism during photosynthesis.

The Preparation Of Laboratory Specimens As An Aid To The Diagnosis Of Animal Diseases, L. Van Es, L. V. Skidmore

Nebraska Agricultural Experiment Station: Historical Circulars

Many problems in connection with animal diseases require for their solution the application of methods which can only be undertaken at properly equipped laboratories. This ordinarily involves the collection, packing, and shipping of samples of specimens. The manner in which this is done is a most important factor and to a very large extent is responsible either for the success or for the failure of the undertaking. The discussion of the subject to which the following pages are devoted is taken in hand in the hope that it may provide guidance to the veterinarians and others who may have occasion …

The Common Intestinal Roundworm Of Swine (Ascaris Lumbricoides), 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.

Late Spring Management Of The New Strawberry Bed, A. L. Ford

SDSU Extension Circulars

One of the most essential things in successful strawberry growing is a proper amount of the right kind of cultivation. No boy or girl club member can ever expect to break club yield records without cultivation (hoeing) his patch. Why is it that cultivation is so necessary in strawberry growing? There are four principal reasons, and they are taken up separately below. (See more in text).

Planting The Strawberry Bed, A. L. Ford

SDSU Extension Circulars

You have probably ordered your plants by this time and would, undoubtedly, want to know how much ground to prepare for them. In speaking of strawberry beds we will use the square rods as the unit area. The number of plants necessary for a square rod of ground depends entirely upon the planting system you choose to use. There are three common systems of planting and training strawberry beds, namely, (1) the hill system, (2) the hedge row system, (3) and the matted row system. These are taken up separately below.
