Bulletin No. 156 - The Irrigation Of Sugar Beets, F. S. Harris May 1917

Bulletin No. 156 - The Irrigation Of Sugar Beets, F. S. Harris

UAES Bulletins

The sugar beet crop during the last few years has come to be one of the most important sources of income for farmers in many sections of the country. The fact that the sale for the crop is certain at a price that is known in advance, in addition to the high type of farming that usually accompanies sugar beet raising, makes it probable that the sugar beet area will be considerably extended during the next few years.

Bulletin No. 150 - Further Studies Of The Nitric Nitrogen Content Of The Country Rock, Robert Stewart, William Peterson May 1917

Bulletin No. 150 - Further Studies Of The Nitric Nitrogen Content Of The Country Rock, Robert Stewart, William Peterson

UAES Bulletins

The progress of the work upon the general problem of the origin of the nitre spots in certain western soils has presented several different points of view. The fact that certain spots in western cultivated soils were rich in nitrates was first observed by Hilgard who attributed their accumulation to the more rapid nitrification of the organic matter of the soil in the warm arid climate of the west when the moisture limit was removed by irrigation.

Ecological Studies In The Tension Zone Between Prairie And Woodland, J. E. Weaver, Albert F. Thiel Apr 1917

Ecological Studies In The Tension Zone Between Prairie And Woodland, J. E. Weaver, Albert F. Thiel

Department of Agronomy and Horticulture: Faculty Publications

Upon the completion of a series of investigations in southeastern Washington and adjacent Idaho, in which there was found to be a direct relation between the available water content of the soil and the evaporating power of the air as succession progressed from grassland through scrub to forest, the senior writer moved to Minneapolis, Minnesota. Here such excellent conditions of prairie invaded by scrub and followed by forest offered themselves for study that the services of the junior author were enlisted and an analysis of the situation attempted. Later this study was supplemented by similar work carried on at Lincoln, …

Bulletin No. 153 - Selecting Dairy Bulls By Performance, W. E. Carroll Apr 1917

Bulletin No. 153 - Selecting Dairy Bulls By Performance, W. E. Carroll

UAES Bulletins

Success in any system of breeding requires that each generation approach more nearly the object in view than has all preceding generations. Such progress is possible only when proper judgment is exercised and the best methods employed. In cattle breeding, for economic reasons, the bull is usually expected to contribute more to this general improvement than is the cow. To make this possible, the bull must therefore have been subjected to more rigid selection than the cow in order to eliminate more of his undesirable characters. If he contains few undesirable characters, from the breeding standpoint, he must of necessity …

Circular No. 25 - Preserving Eggs For The Home, Byron Alder Apr 1917

Circular No. 25 - Preserving Eggs For The Home, Byron Alder

UAES Circulars

The preserving of eggs in the home from the spring when they are so plentiful until fall and winter when they are so scarce, is by no means a new practice. Only a very few, however, are taking advantage of this practice and the full benefits are by no means being derived. During the past winter the high cost of eggs has brought this fact out very forcibly in some of the rural districts as well as in the larger cities where the price for a considerable time was from 50 to 60 cents a dozen and only a limited …

Bulletin No. 151 - The Freezing Of Fruit Buds, F. L. West, N. E. Edlefsen Feb 1917

Bulletin No. 151 - The Freezing Of Fruit Buds, F. L. West, N. E. Edlefsen

UAES Bulletins

There are many orchards in this country, so located that every few years a frost almost completely destroys the crop, either by killing the buds in the spring of the year, or by freezing the fruit in the fall, just before it is picked. Utah is no exception. A report made by the county agricultural agents of the state, shows that in the spring of 1916, 85 percent of the apples, 90 percent of the peaches, and 65 percent of the mall fruit were killed by frost with a corresponding amount of damage to field crops.

Bulletin No. 152 - The Effects Of Soil Moisture Content On Certain Factors In Wheat Production, F. S. Harris, Howard J. Maughan Feb 1917

Bulletin No. 152 - The Effects Of Soil Moisture Content On Certain Factors In Wheat Production, F. S. Harris, Howard J. Maughan

UAES Bulletins

A knowledge of the intimate relations between the crop and the moisture of the soil is important to every farmer, and particularly to those in the arid parts of the world. While wheat is not an intensive crop and probably will not give as great returns to the acre for extra care as some other crops, it is well worth while to know how this crop responds to various treatments. The effect of high and low soil moisture during various stages in the growth of the crop is of particular interest. The work of other experimenters on this subject has …

New Hymenoptera, J. C. Crawford Jan 1917

New Hymenoptera, J. C. Crawford

Co

Professor Cockerell has recently (Psyche, XXIII, 176- 178, 1916) published on the synonymy of this group, and at present it seems best to treat Zacesta and Panurgomyia as synomyms of this genus. Z. rufipes is very similar to the genotype of Hesperapis and is probably the male of a very closely allied species. Panurgomyia fuchsi belongs to the group of H. eumorpha and (Panur-gus) H. regularis Cress. and is very close to regularis. The type of fuchsi is in bad condition and the identification is, therefore, somewhat' uncertain.

A Study Of The Vegetation Of Southeastern Washington And Adjacent Idaho, J. E. Weaver Jan 1917

A Study Of The Vegetation Of Southeastern Washington And Adjacent Idaho, J. E. Weaver

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

Noone at all botanically inclined can travel through southeastern Washington without being impressed with the marked changes which a distance of only a few miles may show in the vegetation. Traveling eastward from a point fifty miles west of the Idaho state line, one passes from a region of scab-land sagebrush through one of rolling hills covered with bunch-grasses. Upon steadily ascending the great Columbia Plateau, the 'bunchgrasses give way to well developed prairies, and these in turn, near the Idaho line, to forests of yellow pine, Douglas fir, white fir, tamarack, and cedar. Or starting from Spokane in the …
