Bulletin No. 175 - Sixteen Years Of Dry Farm Experiments In Utah, F. S. Harris, A. F. Bracken, I. J. Jensen

UAES Bulletins

The demand for reliable information on dry-farming is increasing every year. As the area that is being cropped by dry-farm methods extends to less favorable regions, it becomes necessary to utilize the most effective methods of culture. In choice dry-farm sections crops may be produced without special care; but when an attempt is made to farm where the rainfall is low or where other conditions are not favorable, it becomes necessary to use every possible means of moisture conservation in order to get satisfactory yields.

Since the demand for information is so insistent, it seems desirable at this time to …

Bulletin No. 174 - A Variety Survey And Descriptive Key Of Small Grains In Utah, George Stewart

UAES Bulletins

Standardization of the varieties of small-grains in Utah is highly important. A mixed condition of grain causes both direct loss and inconvenience. The loss comes about in two principal ways: (1) by the decreased yields resulting from mixed grain, and (2) by the lower price paid for each bushel of mixed grain. This latter loss is especially noticeable in wheat on account of the grading system which penalizes mixed wheat by reducing the grade or by barring it from one of the six market classes and designating it as "mixed" wheat. The inconvenience arises from the fact that some varieties …

Potato Seed Certification In South Dakota, Frank E. Mccall

SDSU Extension Circulars

The introduction of dangerous potato diseases, (notably powdery scab and black wart) along with Federal grade regulations and the demands of many states that potatoes for propagating purposes be certified—as to purity and freedom from diseases—has aroused unusual interest in the standardization of potato shipments from the various northern potato growing centers. Early in 1919, the potato growers of the state felt an urgent need for definite lines of potato improvement. Accordingly, a plan for inspection and certification of potato seed stock was inaugurated. This move was entirely voluntary on the part of the·potato growers and was placed under the …

Bulletin No. 172 - The Value Of Barnyard Manure On Utah Soils, F. S. Harris

UAES Bulletins

New countries rarely appreciate the value of barnyard manure. It is not until the soil begins to be depleted of its fertility and the yield of crops begins to decline that manure is given the attention that its value justifies. In new countries it is not uncommon to see manure hauled into a rut in the road or left in scattered heaps along the roadside or the ditch bank. Often a year's accumulation of manure is drawn out of the barn or corral in scrapers and added to a pile containing the accumulation of previous years.

Bulletin No. 173 - The Duty Of Water In Cache Valley, Utah, F. S. Harris

UAES Bulletins

The greater part of this bulletin is devoted to a report of experiments on the relation of the amount of irrigation water applied to the yield of crops. As the agriculture of Utah develops, it becomes more obvious each year that the chief factors limiting the production of crops is irrigation water. It is desirable, therefore, to have available all possible information on the subject. Water is so scarce that none should be wasted either directly or by attempting to spread it over so much land that it is not economically applied. Wasteful extravagance on the one hand and undue …

A Suggested Farm Entrance Sign For Advertising Purposes, Ralph L. Patty, Geo A. Starring

SDSU Extension Circulars

With the great increase in the number of farmers who are adopting names for their farmsteads, there is an accompanying desire for the erection of appropriate sign boards, entrance signs, or other devices of advertising value. The accompanying sketch and working plan are intended to show what may be done with ordinary building materials in erecting a sign that has good lines. Farmers who contemplate the putting up of two posts and a straight cross board may find in this suggestion something worthwhile. If the sign is worth erecting at all, why not put up one that is attractive? Many …

Bulletin No. 171 - Alfalfa Seed Growing And The Weather: With Particular Reference To Conditions In Utah, J. Cecil Alter

UAES Bulletins

The demand for alfalfa seed has far outrun domestic production. Since the labor and expense of producing the crop are light, and the profits attractive in favorable years, a desire is manifest wherever alfalfa is grown, to save a crop for seed whenever the meteorological elements favor its setting and maturing. Climate is generally acknowledged to be the limiting factor in alfalfa seed production, and the current weather the major factor affecting the yearly yields.

The Balanced Garden, Frank E. Mccall

SDSU Extension Circulars

The body needs protein, carbohydrates, and fats in a quite well-defined ratio. This ratio can be most easily provided if balanced meals are served. It will be much easier to serve balanced meals if the foods containing the proteins, carbohydrates, and fats are produced in or near the right proportions. If the garden is depended upon for the bulk of the food supply, then the varieties grown should be selected upon this basis.

Hymenoptera Collected Near Boston, Mass., With Descriptions Of A Variety Of Bombus Affinis, Joseph Bequaert

Ba

While collecting Hymenoptera at Forest Hills, Mass., and other localities in the vicinity of Boston, I have taken on two occasions a bumble-bee, which from its aberrant coloration could not be properly named with Franklin's "Bombidae of the New World." I have been permitted to examine similarly colored Bombus, taken some years previous by Professor Wheeler at Forest Hills and by Mr. J. E. Smith at Sherborn, Mass. It was finally recognized that all these specimens belong to a striking color-variant of Bombus affinis, which it is the purpose of this note to describe and name. I have used this …

Circular No. 41 - Soil Alkali, F. S. Harris

UAES Circulars

The farmer of the West is likely to be very much upset at the mention of alkali, mineral, or salt, in connection with his land. These various names are applied to a condition which he usually knows little about except that it is bad. The exact nature of the substances called by these names and the character of the injuy caused by them are very vague in his mind; but he knows that he wants nothing to do with alkali if he can help it.

The prevalence of alkali throughout the arid parts of the world makes it impossible for …

Bulletin No 81 - The Improvement Of Pastures With Notes On The Pasture Trefoils In Western Australia, E. A. Mann, D. A. Herbert

Bulletins 1 - 2999

Agriculture can be roughly divided for practical purposes into two large divisions, those of animal husbandry and vegetable husbandry. It is with the former that this pamphlet is chiefly concerned and its object is to contribute, it possible, in some small measure towards the problem of how to increase time stock carrying capacity of our natural pasture lands. it is unnecessary to dwell upon the importance of this question, especially in relation to the remarkable developments which are taking place in time wool-growing industry in the Southern and more coastal areas of Western Australia.

Bulletin No 80 - Cultivation Of Sugar Beet, Percy G. Wicken

Bulletins 1 - 2999

The beet belongs to the Chenopodiaceae or Salsolaceae, an order of plants which include among them many of the native saltbushes. The sugar beet (Beta vuigaris crassa) is supposed to have been developed from the wild beet (Beta vulgaris maritima), which is indigenous to the countries along the coast of Southern Europe. it is a biennial plant—that is, of two years' duration. The first year it produces a full-sized root, the second year it produces its seeds, and then dies off. Sometimes a few plants Produce seed the first year, but this is only on account of the seed being …
