Effect Of Position Within A Large Storage Bin Upon Midwinter Behavior Of Nebraska Triumph Seed Potatoes, H. O. Werner Feb 1949

Effect Of Position Within A Large Storage Bin Upon Midwinter Behavior Of Nebraska Triumph Seed Potatoes, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Much variation in time of emergence of plants has been observed within lots of Nebraska seed potatoes planted in the South during the winter. In large storage bins in western Nebraska the end of the dormancy period of tubers in various parts of the bin, as determined by the appearance of sprouts, may vary from January to May. It has been surmised that differences in temperatures and perhaps other conditions in various parts of the bin may account for such variations. In the winter of 1941-42 an experiment was conducted to determine the extent to which the position of potatoes …

The Chromosomes Of The Yeast Cell, Donald William Penn Feb 1949

The Chromosomes Of The Yeast Cell, Donald William Penn

Bachelors’ Theses

Saccharomyces cerevisiae has long been a fungus of economic importance in the baking and beverage fields. A large amount of research has been done on this yeast cytologically and biochemically. However, due to its small size and difficulty in staining, the cytology of the yeast cell remains somewhat in question. Chromosomes and division figures have been demonstrated by several workers, but there still remain sharp differences of opinion as to the nature of the nucleus. Recent work on the genetics of yeast has shown evidence of chromosome division similar to that occurring in higher plants and studies of linkage have …


Some Additional Observations On The Morphology Of Dendrouterina Botauri Rausch, 1948 (Cestoda: Dilepididae), Robert L. Rausch Feb 1949

Some Additional Observations On The Morphology Of Dendrouterina Botauri Rausch, 1948 (Cestoda: Dilepididae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The scolex has never been described for cestodes of the genus Dendrouterina Fuhrmann, 1912. The two species belonging to this genus, D. herodiae Fuhrmann, 1912, and D. botauri Rausch, 1948, were described from incomplete material. Because of the lack of a scolex, this genus was only tentatively placed by Fuhrmann (1912) in the family Dilepididae.
Persistent collecting during the spring migration of 1948 made possible the examination of a number of bitterns, Botaurus l. lentiginosus (Montagu). A single bird, collected on May 5, 1948, at Madison, Wisconsin, was found to be infected with two specimens of Dendrouterina botauri. Observations …

4-H Club : Meal Planning "B" Plan, Agricultural Extension Service, South Dakota State College

SDSU Extension Circulars

The B-Plan is to help you with the planning and preparing of luncheons or suppers. The number of meals per day is a matter of custom. Our three meals are breakfast, luncheon and dinner. We eat one light meal (breakfast), one moderate meal (luncheon or supper) and one heavy meal (dinner). In this plan we are concerned with the moderate meal. Noon seems like the favored time for this meal. There is more variety in luncheon menus than in breakfast menus. Such factors as age, sex, occupation, state of health, habit and season influence what we eat at each meal. …

Bulletin No. 333 - Drainage Districts In Utah: Their Activities And Needs, J. Howard Maughan, Orson W. Israelsen, Eldon G. Hanson Jan 1949

Bulletin No. 333 - Drainage Districts In Utah: Their Activities And Needs, J. Howard Maughan, Orson W. Israelsen, Eldon G. Hanson

UAES Bulletins

The need for drainage in Utah was widely recognized before 1900, resulting in passage of a drainage district law in 1896 and provision for cooperative drainage research beginning in 1904. The drainage district laws, developed and improved during the half-century ending 1948, have served as the major basis for drainage organization in the state.

Bulletin No. 336 - Utah Agricultural Experiment Station Biennial Report, 1946-1948, R. H. Walker

UAES Bulletins

During the past biennium there has been a general expansion in the research program of the Agricultural Experiment Station. This was made possible through increased state legislative appropriation and through federal funds made available by the Agricultural Research and Marketing Act which passed Congress in August 1946, although funds were not available until August 1947. Grants-in-aid by state and private agencies have also made other research possible.


Forest Resources And Industries Of Missouri, D. B. King, E. V. Roberts, R. K. Winters Jan 1949

Forest Resources And Industries Of Missouri, D. B. King, E. V. Roberts, R. K. Winters

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Missouri's forests occupy more than 15 million acres, one-third of the land area of the state. Practically all of this area is classified as commercial forest land. The noncommercial forest lands aggregate less than 1 percent of the total forest area. Two-thirds of all the commercial forest land is in the rugged Ozark region south of the Missouri River. Ninety percent of the commercial forest land is privately owned and is almost equally divided between farm and nonfarm owners. The Clark and Mark Twain National Forests contain 8 percent of the total, and the remaining 2 percent is divided between …

4-H Club : Home Life Project "A" Plan, Agricultural Extension Service, South Dakota State College

SDSU Extension Circulars

The living room should be so planned and arranged that all members of the family enjoy it. This room should be comfortable, convenient, and pleasant. It should provide space for the interests of each member and it should express a spirit of welcome to guests. After a family planning session you'll probably find that your family wants the living room to include a reading unit, a conversation unit, a writing unit, a sewing unit and possibly a music unit.


Rb160 Pink Rot Of Potatoes Caused By Phytophthora Erythroseptica Pethyb., R. W. Goss Jan 1949

Rb160 Pink Rot Of Potatoes Caused By Phytophthora Erythroseptica Pethyb., R. W. Goss

University of Nebraska-Lincoln Extension: Historical Materials

During the summer of 1943 reports were received of rotted tubers occurring in fields of early potatoes in central Nebraska. The fact that the tuber rot was present at harvest time and was associated with the early death of the plants rather than occurring as a postharvest disease indicated the presence of a disease factor previously unreported in Nebraska.

A Half Century Of Crop Rotation, Theodore Eugene Odland, Albert L. Owens, Robert Smith Bell Jan 1949

A Half Century Of Crop Rotation, Theodore Eugene Odland, Albert L. Owens, Robert Smith Bell

Special Collections (Miscellaneous)

Fifty-three years of crop rotation studies, started in 1894, were concluded in the fall of 1946. These experiments were on Bridgehampton very fine sandy loam soil that was originally acid and produced meager crops. Within a very few years it became evident that the yields of crops could be materially increased by the use of agricultural lime and chemical fertilizers. The records of the last 17 years of the experiments are reported in this bulletin and comparisons are made with results from former years. The 3 rotations described in this bulletin are known as rotations B, E, and F. B …
