The Effect Of A Controlled Nitrogen Supply With Different Temperatures And Photoperiods Upon The Development Of The Potato Plant, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The potato (Solanum tuberosum Linn.) is grown under a great variety of conditions with regard to temperature, length of day, intensity and character of light, texture, fertility, and moisture of soil, and atmospheric humidity. There is need for a better understanding concerning the internal response of the potato plant to these external conditions when they are applied, either singly or in combination with each other, and the resulting morphological response, especially with regard to the tuberization process. It has been the object of this investigation to determine the relation of the nitrogen supply to the processes of stolon and …

UAES Bulletins

This is the first of a series of bulletins based on a study of Utah village life 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.

Nuclear And Cell Division In The Root Tip Of Iris Versicolor, Mary Maxentia Mahoney

Bachelors’ Theses

The writer found that very little work has been done on the somatic mitosis of Iris versicolor L. Some interesting accounts of karyokinesis in the root tips of some monocots have been written. Schaffner (1898) made a detailed study of nuclear and cell division in the root tips of the Allium cepa. He observed that the spindle originated from centrospheres, and that the most typical resting nuclei occured some distance back of the tip beyond the actively dividing region. In good stained material the resting nuclei had one or two large nucleoli and a very distinct chromatin net …

Bulletin No. 248 - Results Of Seven Years Of Egg-Laying Contests, Byron Alder

UAES Bulletins

The Utah Intermountain Egg-Laying Contests were begun on November 1, 1924, and continued until October 23, 1931. Up until this time the interest in poultry-breeding for egg production in this intermountain section was extremely limited; furthermore, there were few flocks on which trap nest and pedigree breeding records were kept.

The primary object in conducting these contests was to stimulate an interest in the breeding of better poultry. An egg-laying contest makes it possible for the poultry raiser, trying to get started in poultry-breedng work on a limited scale, to obtain accurate individual egg records of some of his pullets …

The Prairie, J. E. Weaver, T. J. Fitzpatrick

Department of Agronomy and Horticulture: Faculty Publications

This research is the third of a series of investigations of the prairie. The first dealt with the environment of the prairie (Weaver and Himmel, 1931). The second was concerned with the ecology and relative importance of the dominant grasses (Weaver and Fitzpatrick, 1932). The present study treats of the structure of the vegetation in the several types of prairie, the secondary grasses, the ecology of the forbs, together with a general survey of contacts, invasion, and succession. These investigations have resulted from years of intimate association with the great grasslands of North America. They were made in an endeavor …

Bulletin No. 247 - Effect Of Manure And Of Phosphorus Fertilizer On The Yield And Composition Of Alfalfa Hay, D. W. Pittman

UAES Bulletins

It has frequently been observed by practical stockmen that alfalfa hay produced on poor unproductive land has a much lower feeding value than hay produced on good productive land. Some have also observed that by the use of a supplemental feed rich in phosphorus (such as steamed bone-meal), the feeding value of this poor quality alfalfa hay may be improved, indicating that phosphorus deficiency is at least one cause of its low feeding value.

Bulletin No. 246 - Food Habits Of Rural School Children In Relation To Their Physical Well-Being, Almeda Perry Brown

Bulletin No. 245 - Cherry Pollination Studies In Utah, Francis M. Coe

UAES Bulletins

The cherry is rapidly becoming Utah's most important fruit crop. According to the 1930 census, there were 110,050 bearing and 114,230 non-bearing cherry trees in Utah orchards. Most of these trees are sweet cherries, the newer plantings consisting mainly of Bing and Lambert trees, although Napoleon predominated in the older plantings.

The problem of pollination is of more importance with the cherry than with other- fruits, because of the large number of individual fruits required to make a crop and because of the self-sterility and intersterility shown by the major commercial sweet varieties.

As has been shown by the investigations …

Cephalosporium Wilt And Die-Back Of The White Elm, R. W. Goss, Paul Raymond Frink

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A new disease of the white elm has been found to be common in eastern Nebraska. The causal organism has been isolated and its pathogenicity proved by inoculation. The fungus belongs to the genus Cephalosporium and is considered to be the same as that described by Curtis May of Ohio and found by him in specimens obtained in Iowa, Missouri, New York, and Washington, D.C. The morphology and cultural characters of the organism are described.

The Effect Of Fertilizer Applications On The Quality And The Quantity Of The Oil In Flaxseed, Clarence O. Stockland

Electronic Theses and Dissertations

A considerable number of economic seeds are characterized by the presence of oil instead of starch as reserved material. The flax plant produces an oil-bearing seed which yields either by pressure or by extraction an oil which is used chiefly in the manufacture of paints and varnishes, and in the manufacture of linoleum, oil cloth, printer's ink, and patent leather. The oil obtained from flexseed is known as linseed oil and is one of a class of fatty oils known as drying oil. When exposed to the air the oil absorbs oxygen, forming a compound known ad linoxyn which constitutes …

Improving The Farm Environment For Wild Life, Wallace B. Grange, W. L. Mcatee

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

As farms replace virgin lands, whether forest or swamp, marsh or prairie, conditions affecting wild life are revolutionized. Some creatures, especially the larger ones, disappear. Others are benefited, at least during the earlier stages of agriculture, and increase in numbers. This is true of nearly all birds up to the size of the crow and of mammals to that of the rabbit. As agriculture becomes more intensive, however, and woods are cut down, hedgerows eliminated, and rough nooks here and there brought under cultivation, conditions become unfavorable for the smaller forms of wild life.

Uniform mature forest, uniform swamp, or …

Relation Of The Differential Fertilization Genes, Ga Ga, To Certain Other Genes Of The Su-Tu Linkage Group Of Maize, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

The Ga, or “gamete” gene of maize can be studied only or principally by its disturbance of normal Mendelian ratios of contrasted characters differentiated by genes linked with it. The amount of this disturbance can be used as a measure of the intensity of linkage between Ga and other genes of the su-Tu group.

Disturbance of the 3:1 ratio of starchy, Su, to sugary, su, endosperm has been most studied. In one of the early papers on Mendelian inheritance, Correns (1902) reported that, although crosses between most starchy and sugary varieties gave an F₂ ratio of …

Effect Of Frequent Clipping On The Development Of Roots And Tops Of Grasses In Prairie Sod, Harold Biswell, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

A study has been made of the regeneration of bluestem grasses in ex- closures in continuously grazed native pastures. The persistence of remnants of the bunches or mats of sod in old pastures for a long period of years is of interest, as is also their gradual but slow rate of recovery under protection when they are greatly weakened. Even in low, fertile, well watered soil, a period of three or four years must elapse before such species as Andropogon furcatus and Sorghastrum nutans produce the usual abundance of flowers stalks and large quantities of viable seed. The first summer …

The Relation Of The Native Forest Cover To The Physical And Chemical Nature Of The Soils Of The Mammoth Cave National Park Area, Sheppard Walker

Masters Theses & Specialist Projects

This study was undertaken for the purpose of determining the relation existing between the native forest cover and the chemical and physical properties of the soils of the Mammoth Cave National Park area. The study was suggested by certain references in the literature to a correlation existing between forest cover and the geological, chemical and physical nature of soils of this area. The recent attempt at reforestation in the Mammoth Cave National Park area renders such a study timely, and it is believed that the results reported in this paper will materially aid the Mammoth Cave National Park Commission and …
