Weeds In Sacramento County Of California, Ross Clover Jan 1937

Weeds In Sacramento County Of California, Ross Clover

University of the Pacific Theses and Dissertations

Sacramento County has many types of Agriculture and many weed pests which compete with the crops. Stock may be poisoned by certain weeds and weeds may also act as hosts for fungus diseases, virus diseases and insect pests of cultivated crops. Many plants may be weeds in one locality and harmless or beneficial in other parts. The author has made a thorough study of the country's agriculture and its weeds. Latest control practices were also studied.


Cellar And Cold Storage Of Sound And Mechanically Damaged Triumph Seed Potatoes, H. O. Werner Dec 1936

Cellar And Cold Storage Of Sound And Mechanically Damaged Triumph Seed Potatoes, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The object of these experiments was to determine with practically sound, whole potatoes the effect of cold storage during various portions of the storage period and continual cellar storage upon: (a) the weight losses during numerous intervals of storage period; (b) the condition of the potatoes at the end of the storage period in June; and (c) the relative seed value of the various lots of potatoes as determined by field experiments.


Bulletin No. 275 - Types Of Farming In Utah, Marion Clawson, Walter U. Fuhriman, George T. Blanch, W. Preston Thomas Nov 1936

Bulletin No. 275 - Types Of Farming In Utah, Marion Clawson, Walter U. Fuhriman, George T. Blanch, W. Preston Thomas

UAES Bulletins

A large portion of the agriculture of Utah, outside of the desert range areas, is characteristically heterogeneous rather than homogeneous in character. Marked differences in size of farm, in crops grown, in livestock kept, in yields, and in farm organization occur within short distances. This diversity is due in large measure to differences in soil, elevation, topography, and other physical features and to climatic characteristics such as amount, kind, and distribution of precipitation and length of growing season. The physical and climatic features are the chief determinants of the amount of water potentially available for the irrigation of the crop …

Spruce In The Western Miocene, George F. Beck Nov 1936

Spruce In The Western Miocene, George F. Beck

All Faculty Scholarship for the College of the Sciences

One of the real surprises in store for us as we began to section specimens of petrified wood from the Vantage and certain other horizons in Central Washington, was the prevalence of a spruce type hardly hinted at in the leaf lists as published for the various sediments of Yakima time (upper miocene?).


Bulletin No. 274 - Influence Of Rotation And Manure On The Nitrogen, Phosphorus, And Carbon Of The Soil, J. E. Greaves, C. T. Hirst Oct 1936

Bulletin No. 274 - Influence Of Rotation And Manure On The Nitrogen, Phosphorus, And Carbon Of The Soil, J. E. Greaves, C. T. Hirst

UAES Bulletins

All agricultural plants require carbon, hydrogen, oxygen, nitrogen, calcium, potassium, magnesium, sulfur, phosphorus, iron, and probably traces of other elements for their normal growth and fruition. The growth of farm crops is dependent upon an available supply of these elements, and the extent of growth is governed by the one present and available in least quantity in proportion to the plant's needs. Of the essential elements, all plants secure two (carbon and oxygen) from the air, one (hydrogen) from the water, and the others from the soil. Most soils contain sufficient plant nutrients for normal plant production, with the exception …

Bulletin No. 273 - Drainage And Irrigation, Soil, Economic, And Social Conditions, Delta Area, Utah, Division 3: Economic Conditions, W. Preston Thomas, George T. Blanch

UAES Bulletins

Project 90-A Study of Factors Influencing the Financial Condition of Certain Utah Irrigation and Drainage Projects-was undertaken in 1928 as an intensified study of local areas. This study was divided among four departments, with a project leader for each particular phase of the study. These four project leaders, guided by the Station Director, have constituted a committee in immediate charge of this project. Subprojects and their respective leaders have been: A-Engineering and Engineering Economic Aspects, O. W. Israelsen; B-Soil Productivity Aspects, D. S. Jennings; C-Contributing Sociological Aspects, J. A. Geddes; and D-Economic Aspects, W. Preston Thomas.

Effects Of The Great Drought On The Prairies Of Iowa, Nebraska, And Kansas, J. E. Weaver, F. W. Albertson

Department of Agronomy and Horticulture: Faculty Publications

The response of prairie vegetation of eastern Nebraska during the great drought of 1934 has been described (Weaver, Stoddart, and Noll, '35). The purpose of the present study was to determine the results of the drought during the following year. The work has been extended to include the mixed prairie of west central Kansas.

Seasonal Variation Of The Pigment Content Of Acer Saccharum & Tilia Americana, James Major Aug 1936

Seasonal Variation Of The Pigment Content Of Acer Saccharum & Tilia Americana, James Major

Masters Theses & Specialist Projects

Leaves of the sugar maple and the American linden were selected. Since it was impossible to control environmental factors in any way, trees growing in close proximity were used. A sugar maple and an American linden growing near the entrance to the circular drive between Ogden Hall and Snell Hall on the campus of Western Kentucky State Teachers College, Bowling Green, Kentucky, fulfilled the above conditions.

Reports From "Drought Front" Tell State Or Vegetation, J. E. Weaver Jul 1936

Reports From "Drought Front" Tell State Or Vegetation, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Development of the natural prairie vegetation is an excellent indicator of the intensity of drought. The extreme drought of 1934 left many bare areas in the grasslands and all but swept away most of the least drought-resistant species. The dry early spring and later summer of 1935 witnessed great increases in needlegrass, western wheat grass, and the invasion of a host of weeds. The favorable spring of 1936 promoted an abundant growth and emphasized the great changes in the prairie flora.


Bulletin No. 272 - Transmissibility Of Bang's Disease Among Dairy Cattle In A Utah Dairy Village, D. E. Madsen, O. G. Larsen Jul 1936

Bulletin No. 272 - Transmissibility Of Bang's Disease Among Dairy Cattle In A Utah Dairy Village, D. E. Madsen, O. G. Larsen

UAES Bulletins

For a number of years it has been generally recognized that one of the most satisfactory methods of controlling Bang's disease in dairy cattle is to locate spreaders by means of the agglutination test and to eliminate them from the herd. The success of such a plan in relation to Utah dairy herds was not clearly understood because of the physical farm set-up peculiar to many communities in this state. The village of Hyde Park where this study was made is organized on such a community basis. Usually, a house and livestock buildings are constructed on the town lot, consisting …

The Development Of The Embryo Of Iris Missouriensis Nutt, C. Eugene Larsen May 1936

The Development Of The Embryo Of Iris Missouriensis Nutt, C. Eugene Larsen

Theses and Dissertations

There is but a single species of Iris native to Utah. This is Iris missouriensis Nutt. This plant was chosen for investigation because of its possible significance and because material of this species was readily available. The embryo of Iris missouriensis Nutt. shows some resemblance to the Lily type in its development of an irregular dividing suspensor. It also resembles the Orchid type in the usual development of sixteen cells before the dermatogen is cut off. In general development, however, the writer believes it to have an embryo sequence more similar to the Alisma type than to the dexcriptions given …

Bulletin No. 269 - Farm Versus Village Living In Utah, Joseph A. Geddes Mar 1936

Bulletin No. 269 - Farm Versus Village Living In Utah, Joseph A. Geddes

UAES Bulletins

This is the second of a series of bulletins based on a study of Utah village life which was begun in 1927. The purpose of the investigation was to determine, under prevailing conditions, whether for farm people farm-living is less desirable than village-living. Four type villages were selected in as many counties for field studies.
