Agricultural Productive Capacity 1955 South Dakota, South Dakota Agricultural Experiment Station Nov 1951

Agricultural Productive Capacity 1955 South Dakota, South Dakota Agricultural Experiment Station

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

Our agricultural resources have a strategic role to play in the present mobilization effort. Even a partial military mobilization calls for a large increase in food. Our population has increased by 20 million people since 1940. Our civilian per capita food consumption is up 13 percent, our agricultural exports are up 50 percent above the 1935-39 average and food surpluses have largely disappeared. Estimates of our agricultural productive capacity are needed to determine whether such capacity is great enough to meet future needs and to help the nation make wise decisions concerning such vital questions as these: 1. How much …

Feeding Milking Shorthorn Steers, M. L. Baker, V. H. Arthaud, C. H. Adams Oct 1951

Feeding Milking Shorthorn Steers, M. L. Baker, V. H. Arthaud, C. H. Adams

Nebraska Agricultural Experiment Station: Historical Circulars

The objectives of the feeding work were to provide the producer with feed-lot data and where possible with slaughter data for Milking Shorthorn steers. As a definite breeding research program with the Milking Shorthorn herd was planned, it also was believed that information about the beef-making qualities of the steers should be of equal importance with milk and butterfat production records.

Geographic Variation In Toads Of The Debilis Group Of Bufo, Ottys Sanders, Hobart M. Smith Oct 1951

Geographic Variation In Toads Of The Debilis Group Of Bufo, Ottys Sanders, Hobart M. Smith

Field and Laboratory

In 1938, Taylor (1938,513) for the first time pointed out the existence of two distinct forms of toads in the assemblage previously referred to Bufo debilis. These he designated as the species Bufo insidior Girard and Bufo debilis Girard. Since then much confusion has reigned, especially with respect to the range and status of the southeasterly form regarded as B. debilis.

Gifts For Family And Friends, Anna D. Walker Sep 1951

Gifts For Family And Friends, Anna D. Walker

SDSU Extension Circulars

Part of the joy in giving gifts comes from the making of something special for a friend or family member. The giving of gifts to mark such events as anniversaries, Christmas and Easter is a long established custom. Looking back into history, we read that tribute was given to show homage to royalty and other people of importance. It was thought that the rarer and richer the gift, the greater was the love and respect shown. Rare spices, perfumes, gold and jewels obtained by the giver at great expense and often much hardship were considered suitable gifts for royalty. People …

Studies On The Helminth Fauna Of Alaska. Vii. On Some Helminths From Arctic Marmots With The Description Of Catenotaenia Reggiae N. Sp. (Cestoda: Anoplocephalidae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Among Alaskan mammals examined for helminthic parasites during 1950 was a series of marmots, Marmota caligata broweri Hall and Gilmore, 1934, from the Brooks Range, Arctic Alaska. The animals were collected a few miles south of Tolugak Lake (lat. 68° 24' N, long. 151° 26' W), and from the vicinity of Kanayut Lake, about 15 miles northeast of Tolugak Lake. This distinctive marmot has been hitherto represented in collections only by the three specimens comprising the type material. In addition to greatly extending the known range of this form, the collection of these specimens also contributes the first information on …

Father-Son Farm Partnerships, Russell L. Berry Jun 1951

Father-Son Farm Partnerships, Russell L. Berry

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

Can parents help their sons and daughters get started farming? The answer is yes. Parents can and do help their children get started farming by making gifts and loans of livestock and machinery and money. Fathers often help their children borrow money and rent land. In South Dakota 19 percent of the land lords reported that they rented some lend to a son or son-in-law. This is just slightly less than the coverage for aJ.1 the states in the Midwest. Inheritance and gifts of land are not uncommon. No less than 24. percent of Midwestern men who are farm owners …

It has long been known that the geographic ranges of certain plants and animals not only closely parallel each other, but also the physiography of their habitat. Indeed, plants and animals seem often to follow clearly certain intangible lines, in their distribution.


The Genus Callirhoe (Malvaceae) In Texas, U. T. Waterfall Jun 1951

The Genus Callirhoe (Malvaceae) In Texas, U. T. Waterfall

Field and Laboratory

All species of Callirhoe known in the United States occur in Texas except C. triangulata. This statement is, of course, dependent on species concept. Callirhoe Bushii, perhaps better treated as a variety of another species, is also not known from Texas. The species C. triangulata has been reported from Texas, but all such material seen by me is referable to C. alcaeoides, since they have the lower leaves only crenate or dentate, rather than lobed or parted as is usual. Sheets of C. triangulata from the Gray Herbarium show Wisconsin, Illinois, Missouri and Alabama as the western limit of that …

Some Economic Aspects Of The Fluid Milk Industry Of Nebraska, Kenneth E. Anderson Jun 1951

Some Economic Aspects Of The Fluid Milk Industry Of Nebraska, Kenneth E. Anderson

Department of Agricultural Economics: Dissertations, Theses, and Student Research

Most citizens of Nebraska, especially the dairy farmers who produced milk for city consumption, are currently concerned with the problem of marketing fluid milk.In Nebraska and all over the United States, sales of wholesale milk farmers have been increasing for the past 15 years, while cream sales to creameries have been decreasing.

Production of milk in Nebraska is greatest in the eastern part of the state.Likewise, consumption is concentrated in Eastern Nebraska. This is most likely due to Eastern Nebraska’s highly concentrated population as well as the most favorable farm conditions for dairy cows.

Most of the bottled milk in …


A Taxonomic Study Of The Catostomidae Of Utah Lake With Notes On The Fish Population, Lyle Junior Lowder Jun 1951

A Taxonomic Study Of The Catostomidae Of Utah Lake With Notes On The Fish Population, Lyle Junior Lowder

Theses and Dissertations

During the period from October 1950 to March 1951 a study of the taxonomy of the Catostomidae of Utah Lake was undertaken. Throughout this study information was collected on the numbers of suckers taken by some of the fisherman. From the data gathered it appears that the three species of Catostomidae cringinally named from Utah Lake are still there. The external morphological features of these fish are not recognizable unless they are observed very carefully. The most outstanding external characteristics used to differentiate the species are the mouth, lips, papillae on the lips and the general shape of the head. …


Ecology Of Passerine Birds Wintering At Utah Lake, Joseph R. Murphy Jun 1951

Ecology Of Passerine Birds Wintering At Utah Lake, Joseph R. Murphy

Theses and Dissertations

During the period of October to April of the winter of 1950-51, an ecological study was undertaken of a population or passerine birds wintering in a segment of the Utah Lake Shore. Available winter weather data indicated that although such factors as precipitation, temperature, and wind may often be severe, they are not critical enough to prevent a fairly large population of passerine birds from spending the winter months in the study locale. Five fairly distinct plant communities can be recognized in the area. There is evidence which indicates that certain passerine bird species are especially dependent on a particular …
