The Quadrat Method In Teaching Ecology, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

The quadrat method of studying vegetation has become an integral part of many of the more important ecological investigations. Although occasionally used throughout the past century for determining the amount of plant material produced or for purposes of enumeration, it was organized into a definite system for the study of the structure and development of vegetation by Pound and Clements (15, 16) and Clements (2, 3, 5) only about eighteen years ago. Since that time it has been used, sometimes in a modified form (12, 21), by numerous investigators both American and European. Indeed, with the rapid increase in the …

Climate And Plant Growth In Certain Vegetative Associations, Arthur W. Sampson

Aspen Bibliography

The relation of climate to the growth and development of vegetation is of profound importance in both practical and experimental agriculture. It is extremely useful to know the cause of successful growth and establishment, or of partial success or failure, of various species in different plant associations and under widely contrasted climatic conditions. The climatic requirements of various plant types are largely responsible for the results obtained in the case of experimental seedings and plantings of most species. Once the adverse climatic factors are definitely known, failures with plants may be largely avoided by the judicious selection of sites or …

Bulletin No. 165 - Labor Costs And Seasonal Distribution Of Labor On Irrigated Crops In Utah Valley, L. G. Connor

UAES Bulletins

This bulletin presents in tabular form the results of a detailed study of the labor cost of crop production, made in 1915. Principally in Utah Lake Valley, Utah, in connection with a study of farm management and farm profits in the Provo area, Utah Lake Valley. It is designed to bring out the weak as well as the strong points in the systems of farming followed. The seasonal distribution of labor is shown for each important crop and the times at which the different crops compete for labor are indicated. The bulletin is intended primarily for the use of farm …

Circular No. 32 - Feeding Farm Animals, W. E. Carroll

UAES Circulars

Our oldest history tells us that in the beginning man was given dominion "over the cattle, and over all the earth." This was of course only potentially possible at first, and could not be realized until man developed and exercised his intelligence to this end. What, then, does it mean to have dominion over the cattle? Is this not merely to control them and direct their energies and productivity to the happiness of mankind? Surely this is so, and that man has greatest dominion who can control them most completely for the good of the race.

Circular No. 33 - A Method Of Feeding Orphan Lambs, W. E. Carroll

UAES Circulars

One of the big preventable losses of the Western sheep business at the present time is the orphan lamb. There are a number of conditions, anyone of which may result in a motherless lamb; the ewe may die (this probably does not occur in a large number of cases) ; a mother may refuse to claim one of a pair of twins or even a single lamb; mother and lamb may become separated by the ordinary moving about of the band of ewes and the ewe thereby loses the scent of the lamb.

The careful shepherd soon detects the orphans, …

Bulletin No. 164 - Factors Affecting The Depth Of Sowing Various Crops, F. S. Harris, H. J. Maughan

UAES Bulletins

Probably no agricultural practice varies more than the depth to which seeds are sown. Some farmers pay very little attention to depth, but simply allow the seed to be placed where the drill happens to penetrate. The percentage germination of the seed as well as the vigor of the young plants is without doubt influenced by the depth of sowing, and certainly these factors are very important in determining the yield of crops.

Boys' And Girls' Club Work : Baby Beef Club, Extension Division, South Dakota State College Of Agriculture And Mechanic Arts And U.S. Department Of Agriculture, Cooperating

SDSU Extension Circulars

The raising and feeding of Baby Beef is the one big coming project in South Dakota. The material increase in the value of farm land is making it impossible to keep feeders to the age of 2 to 3 years before finishing them for market. By careful selection, breeding, feeding, and care an animal can be brought to early maturity and placed on the market in prime condition at from 15 to 20 months of age and bring a higher price per pound than older steers. By marketing beef at the baby stage, much valuable feed is saved on the …

Boys' And Girls' Club Work : Sheep Club, Extension Division, South Dakota State College Of Agriculture And Mechanic Arts And U.S. Department Of Agriculture, Cooperating

SDSU Extension Circulars

Not until the last two years has the sheep raiser come into his own. With the present high prices of mutton and wool there can be no better opportunity offered to the boys and girls of South Dakota than to get into the production of these commodities. There is a serious shortage. The raising of sheep requires less time, expense, and room than does that of any other kind of stock. “A small flock on every farm” is the slogan for South Dakota club members. This will be the result of good club work, and we hope to see one …

Hog Houses For South Dakota, Ralph L. Patty

SDSU Extension Circulars

Good housing is essential to successful hog raising. While several sows may do fairly well with their litters around an old strawstack or shack under favorable weather conditions, it will pay in the long run to figure on good housing and care, if the business is to show the best profit. The circular attempts to put as much helpful material in as little space as possible for anyone planning to build a hoghouse. If changes are made in the plan the details and suggestions should still be of service. It is hard to make changes of any consequence in a …

The Care Of Pullets For Winter Eggs, E. L. Hayes

SDSU Extension Circulars

It is not difficult to secure fall and winter eggs in profitable numbers if we provide suitable conditions and then try to meet those conditions. Such factors as feed, care and even breeding conditions all enter into egg production, but are somewhat limited when compared with early hatching of pullets. Mature pullets of any of the popular breeds will lay winter eggs and there is probably little difference in their actual productive capacity under favorable conditions. There are, however, marked differences in the various breeds with respect to uniformity of color, size or weight of the eggs produced, as well …

Boys' And Girls' Club Work : Sow-Litter Club, Extension Division, South Dakota State College Of Agriculture And Mechanic Arts And U.S. Department Of Agriculture, Cooperating

SDSU Extension Circulars

The demand for more and a better grade of hogs is heard throughout the entire agricultural section of our country. This can be accomplished through careful selection and breeding, followed by the proper methods of feeding and care. Club boys and girls can do much toward bringing this about by entering the sow-litter club. Not only will they find the work profitable, but they will become interested in animal life and the production of quality in pork as well as quantity.

Vegetable Storage, F. E. Mccall

SDSU Extension Circulars

Need of Food. A nation at war is a nation with a food problem. A nation with a food shortage is a nation in peril. In the face of the present world food situation food products of all classes must necessarily be conserved in order that the food demands of the nation may be met. Need of Storage. By the proper storage and utilization of vegetables, larger quantities of the less perishable food products will be released for shipment across the Atlantic, and the people at home will be well supplied with food. This year, the need for proper storage …

Common Parasites Of Swine, J. T. E. Dinwoodie

SDSU Extension Circulars

The publication of this bulletin is designed to convey to hog raisers of this state information regarding some of the common parasites of swine. All of the parasites described herein have been found infesting swine within the state. Some of the parasites may be common in some localities, and uncommon in others. Undoubtedly all sections of South Dakota are in danger at any time of experiencing loss from these parasites.

Farming As A Business, Ward A. Ostrander

This bulletin is a copy of an account book kept by a farmer in South Dakota covering his farm business in 1917-18. It also shows how he summarized it to find the strong and weak points of the business. The purpose of this bulletin is to show how a farm account book can be summarized with a record of the sales, expenses, and inventories. All figures used in the summaries are taken from the record of sales and expenses and inventories.

Annual Report Of The Extension Division For The Year Ending June 30, 1918, C. Larsen, I. B. Johnson, H. E. Dawes, W. M. Mair, Agnes Morton, P. J. Scarbro, Roberta Mcneill, T. A. Meehan, Ward Ostrander, A. E. Miller, W. C. Boardman, G. E. Morrison, R. L. Patty, F. E. Mccall, J. T. E. Dinwoodie, Manley Champlin, J. G. Hutton, A. H. Sherwood, Joe Hill, C. S. Reddy, A. N. Hume, H. C. Gilbert, Ed L. Hayes

SDSU Extension Circulars

The past year has been one of unusual activity along the various phases of agricultural extension. South Dakota had a program of extension mapped out in accordance with the provisions of the South Dakota law enacted in 1915 and 1917, and also in accordance with the federal Smith-Lever Act passed by Congress in May, 1914. With the declaration of war, Congress and those officials in immediate responsibility realized the great importance of supplying our armies and allies with food. In order to speed up the food production program, Congress made an emergency appropriation. This enabled the States, Relations Service to …

Bulletin No. 163 - Composition Of The Irrigation Waters Of Utah, J. E. Greaves, C. T. Hirst

UAES Bulletins

Analytical work which has so far been published on the composition of the irrigation waters of the Intermountain Region indicates a wide variation in their composition. Some are exceptionally pure, being nearly free from alkali, and may be used without fear of injury to soils; others contain larger quantities of alkali and must be used with care; still others are so heavily charged with soluble salts that they must be used with extreme caution, otherwise the growing crop will be injured and in time the soil rendered unfit for agricultural purposes. The land then must be either reclaimed or abandoned, …

Home Canning : One Period, Cold Pack Method, Roberta Mcneill

SDSU Extension Circulars

It is unnecessary to point out at the present time the necessity of home canning. Home canned vegetables and fruits will aid materially in solving present food problems. Of all the methods used in home canning, the one period cold pack process has given the greatest satisfaction. This consists of preparing the material, packing it uncooked in clean jars and sterilizing the material and jars at the same time. The advantages of this method are:
1. Time is saved.
2. Flavor is retained.
3. Spoilage is lessened.
4. Texture is improved.
5. Color is better.
By the method, meats and …

Poisoned Bait As A Control For Grasshoppers, A. H. Sherwood

SDSU Extension Circulars

Grasshoppers have done considerable damage to South Dakota field crops during the past few years. Last year, reports from various parts of the state show severe injury to alfalfa, corn, small grains, gardens, and other crops. The injury usually centers around alfalfa fields, but the grasshoppers attack and destroy almost any green crop available. It have been demonstrated in South Dakota that control measures can be adopted that will serve to keep these insects in check. Natural factors are, of course, important in the control of any insect, and their many enemies greatly reduce the numbers of grasshoppers each year. …

Studies Concerning The Elimination Of Experimental Error In Comparative Crop Tests, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is apparent that many sources of error have unconsciously entered into comparative crop yield tests. The very important matter of overcoming variation in soil conditions as a source of experimental error has been quite extensively studied and reported by various investigators during the past decade. The means suggested for reducing such error have been (1) repetition of plats and (2) correction of yields according to check plats planted to a uniform variety or treatment at stated intervals. Both methods have proved of value and a combination of both may often be used advantageously. Some danger always exists of error …

Destroy The Common Barberry Bush : It Threatens The Wheat Crop, A. N. Hume, C. Larsen, H. C. Gilbert

SDSU Extension Circulars

Why the Common Barberry Must Be Destroyed. It harbors and propagates black stem rust of wheat and other grains. It is a patriotic duty of every one in the state who owns even one bush of the common barberry to dig it out and destroy it and thereby help save the millions of bushels of wheat which are annually destroyed by rust.

Bulletin No. 162 - A Quick Method Of Obtaining Accurate Individual Egg Records Without The Trap Nest, Byron Alder, A. D. Egbert

UAES Bulletins

The power or ability of a hen to lay a large number of eggs or the lack of that power or ability resulting in few or no eggs is not confined to the individuals of anyone breed or flock. Feeding, housing, and general care of the fowls are not the only causes of low production in certain individuals. It is often in the makeup of the hen herself; she could not be a heavy layer under any condition. High and low producers are found in every flock.

An accurate method of obtaining the daily individual records of each bird is …

Circular No. 31 - The Alfalfa Weevil (Phytonomus Posticus Fab.), Harold R. Hagan

UAES Circulars

The alfalfa weevil is rapidly spreading over the entire alfalfa-growing areas of the western states. Its injury to the alfalfa crop still aggregates an enormous sum annually. This is due to the fact that each year it is extending its attack into new territory. Control measures adopted by the farmers are reducing its injury in the treated fields. Many farmers are now cutting more alfalfa in the weevil-infested districts than before the appearance of this pest because of adopting better cultural methods as outlined in Bulletin No. 110 and Circular 10 of this station. Both of these publications are now …
