The Manuscript Works Of S. Fred Prince (1857-1951), Sarah Burke Cahalan, Jason W. Dean 2018 University of Dayton

The Manuscript Works Of S. Fred Prince (1857-1951), Sarah Burke Cahalan, Jason W. Dean

Marian Library/IMRI Faculty Publications

S. Fred Prince, a botanical illustrator and amateur scientist, is a largely unknown artist whose work on the American landscape demonstrates his eligibility to be considered in the lineage of self-taught illustrator-naturalists such as Mark Catesby and Genevieve Jones. In this article, we present a survey of extant Prince materials identified at time of writing, describing their contents and physical characteristics. Beyond this survey and description, we also provide a biographical sketch and timeline of Prince's life.

Decision calendars help identify opportunities for inserting climate information into a decision process as well as points where other considerations might overrule use of the climate information. Developers of decision calendars are challenged, though, by a potentially infinite number of modifications required to address spatial variability in agricultural decision making. Variability in climate, soils, and agricultural production systems across a region may result in deviations in decision-making times.


Controlling Downy Mildew Of Lettuce, A. T. Erwin 2017 Iowa State College

Controlling Downy Mildew Of Lettuce, A. T. Erwin

Bulletin (Iowa Agricultural Experiment Station)

With the rapid development of the greenhouse industry in Iowa in the last decade, lettuce has become the most important vegetable crop grown under glass in this state. In some seasons a disease known as downy mildew is one of the most serious troubles met with in forcing this crop. Competition with garden lettuce from the Pacific Coast and the Gulf States, together with the high cost of production in recent years, makes the control of downy mildew an urgent question with many Iowa growers.

The downy mildew of lettuce, long known as a destructive garden and greenhouse disease, is ...

The soybean cyst nematode Heterodera glycines (SCN) is of major economic importance and widely distributed throughout soybean production regions of the United States where different maturity groups with the same sources of SCN resistance are grown. The objective of this study was to assess SCN-resistant and -susceptible soybean yield responses in infested soils across the northcentral region. In 1994 and 1995, eight SCN-resistant and eight SCN-susceptible public soybean cultivars representing maturity groups (MG) I to IV were planted in 63 fields, either infested or noninfested, in 10 states in the north-central United States. Soil samples were taken to determine initial ...

The soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is distributed throughout the soybean [Glycine max (L.) Merr.] production areas of the United States and Canada (Fig. 1) (26). SCN remains the most economically important pathogen of soybean in North America; the most recent estimate of soybean yield reduction in North America due to SCN totaled 34,659,000 metric tons during 2006 (34).


Potential Of An Alkaline-Stabilized Biosolid To Manage Nematodes: Case Studies On Soybean Cyst And Root-Knot Nematodes, Inga A. Zasada, Felicitas Avendano, Yuncong C. Li, Terry Logan, Haddish Melakeberhan, Stephen R. Koenning, Gregory L. Tylka 2017 United States Department of Agriculture

The use of treated biosolids for pest management and soil nutrient augmentation is not a new practice, but it has increased in the last two decades, primarily in the United States (22). In the late 1970s, the first land application regulations were formulated by the U.S. Environmental Protection Agency (USEPA) in response to the Clean Water Act (44). Land application of sewage sludge for soil amendment and land reclamation has increased over time as a result of the ban on ocean dumping of wastewater residuals (Ocean Disposal Ban Act of 1988). The Act also minimizes other disposal options, such ...


Cold Storage For Iowa Apples: Third Progress Report, W. E. Whitehouse 2017 Iowa State College

Cold Storage For Iowa Apples: Third Progress Report, W. E. Whitehouse

Bulletin (Iowa Agricultural Experiment Station)

This is the third report* of progress on the investigations pertaining to the holding of apples in storage which have been carried on since 1906 by the pomology section of the Iowa agricultural experiment station**. It covers work which has been in progress during the past five years and deals with several questions:

The temperature of fruit before and after storing; humidity of storage rooms; maturity of fruit when stored; size of apples; wrapping paper used in packing, and methods of storing; the control of certain apple rots which are liable to develop in storage, and the rate of cooling ...


Reclaiming Iowa's "Push" Soils., L. W. Forman 2017 Iowa State College

Reclaiming Iowa's "Push" Soils., L. W. Forman

Bulletin (Iowa Agricultural Experiment Station)

Small, practically unproductive areas, known locally as “push” soils, are of rather common occurrence in some sections of southern Iowa. They are found on hillsides, usually about midway down the slope, and the name “push” soil seems to have risen because of the behavior of the soil during plowing. The surface soil is shallow and the underlying material is such a heavy, impervious clay that the plow points will not readily cut it, but tend to pass over the surface, “pushing” the thin top soil aside.

The individual areas of these “push” soils are not large, varying from one-tenth of ...


Corn Supplements And Substitutes For Fattening Lambs, Russell Dunn, John M. Evvard 2017 Iowa State College

Corn Supplements And Substitutes For Fattening Lambs, Russell Dunn, John M. Evvard

Bulletin (Iowa Agricultural Experiment Station)

This test was planned to determine the advisability of adding a protein supplement to a basal ration of shelled com, corn silage, alfalfa hay and block salt for fattening range lambs; to compare the relative value of linseed oil meal, velvet bean feed meal and peanut meal as protein supplements added to the same basal ration; and to note the practicability of replacing the shelled corn in the basal ration with corn gluten feed, a corn by-product.

Linseed oil meal is a well established and popular supplement to corn widely used for lamb feeding. Velvet bean feed meal and peanut ...


Some Weeds Of Iowa, L. H. Pammel 2017 Iowa State College

Some Weeds Of Iowa, L. H. Pammel

Bulletin (Iowa Agricultural Experiment Station)

During the year the Department of Botany receives a great many requests for information on the subject of weeds. These requests come from all parts of the state. Many different kinds of plants are sent in. Some of course, more frequently than others. The writer at different times has given accounts of weeds in the Experiment Station Bulletins. Most of these bulletins are now out of print. It seems advisable, therefore, to re-issue a limited edition to supply the demand for information on this topic. In addition to this we have given a somewhat comprehensive account of the migration of ...


Selecting And Preparing Seed Corn., P. G. Holden, Alfred Atkinson, W. H. Stevenson, W. H. Olin 2017 Iowa State College

Selecting And Preparing Seed Corn., P. G. Holden, Alfred Atkinson, W. H. Stevenson, W. H. Olin

Bulletin (Iowa Agricultural Experiment Station)

The following circular has been prepared in answer to the many letters which are being received daily asking for information regarding the purchasing and testing of seed corn and its preparation for planting.

When we consider that more than nine million acres, considerably over one-fourth of the entire area of the state, will be planted to corn the coming season and that it will require more than 1,300,000 bushels of seed to plant this area; and when we realize that the character of the seed, its vitality, breeding, purity, adaptability to the soil and climate and uniformity in ...


Notes On Strawberries., H. C. Price, E. E. Little 2017 Iowa State College

Notes On Strawberries., H. C. Price, E. E. Little

Bulletin (Iowa Agricultural Experiment Station)

The following pages give the results of a variety test of strawberries begun in the spring of 1899. At this time seventy-five varieties were set in plats ten feet long and each plat containing two rows, four feet apart and the plants twelve inches apart in the row, so that each plat contained twenty plants. The matted row system of culture was used, and the plants were allowed to spread until they formed rows about two feet wide. In the spring of 1900 seventeen more varieties were added to the plantation. The results obtained from the plantation in 1900 were ...

Finishing Western Wethers On Grass And Grain For Early Summer Market., W. J. Kennedy, F. R. Marshall

Bulletin (Iowa Agricultural Experiment Station)

Farmers throughout the central states annually feed and finish for market thousands of sheep. During the past decade a great many farmers have adopted the policy of purchasing western lambs and yearlings during the months of September, October, November and December with the intention of feeding them from sixty to one hundred and twenty days, depending upon the condition of lambs, markets, etc., and then selling them at an advance in price sufficient to return a nice profit on the investment.


A Study On The Germination And Growth Of Leguminosae, Especially With Reference To Small And Large Seed., F. G. Miller, L. H. Pammel 2017 Iowa State College

A Study On The Germination And Growth Of Leguminosae, Especially With Reference To Small And Large Seed., F. G. Miller, L. H. Pammel

Bulletin (Iowa Agricultural Experiment Station)

Practical experience has shown the value of giving much attention to the subject of seed selection. While it is true that the greater number of farmers pay no attention to seed selection, nevertheless the careful farmer and horticulturist is particular about the kind of seed that he plants. And this is especially true of crops like corn, wheat, cotton, oats and potatoes. The majority of farmers pick their seed at random, often without paying any attention to the pedigree or vitality, with the result that their crop is very much reduced. The fact that Dr. Stubbs had increased the sugar ...


Miscellaneous Notes On Fungus Diseases Of Plants. The Canada Thistle And Dandelion. A Few Of The Common Fleshy Fungi Of Ames., L. H. Pammel, Alice Ward Hess 2017 Iowa State College

Miscellaneous Notes On Fungus Diseases Of Plants. The Canada Thistle And Dandelion. A Few Of The Common Fleshy Fungi Of Ames., L. H. Pammel, Alice Ward Hess

Bulletin (Iowa Agricultural Experiment Station)

During the fall of 1901 Miss Estella Rhinehart brought into the laboratory a fungus on the cow pea which caused the leaves to be covered with brown rusty spots. On closer examination this proved to be a genuine rust, Uromyces appendiculatus (Pers.) Link. After looking through the literature I had on hand I was unable to find this rust recorded on this host. The fungus appeared however to be identical with one described on the common bean (Phaseolus vulgaris). Wallroth1 described the aecidium stage as Aecidium Phaseolorum. Saccardo2 does not record the fungus on the cow pea.

The ...


Parturient Paralysis And The Schmidt Treatment., John J. Repp 2017 Iowa State College

Parturient Paralysis And The Schmidt Treatment., John J. Repp

Bulletin (Iowa Agricultural Experiment Station)

This disease is also known by the names parturient paresis, paresis of parturition, parturient fever, milk fever. The word “fever” in connection with the terminology of this disease is not very appropriate, because in the majority of cases fever is not present, but the animal has a subnormal temperature. The term milk fever is very misleading and indefinite, as it is also used by the laity to designate other diseases, such as parturient septicaemia and the various forms of mammitis. Parturient paralysis must be clearly differentiated from parturient septicaemia, which is a disease of an entirely different character and which ...

Gregory Tylka

Soybean cyst nematodes (SCNs), Heterodera glycines, are unwanted micro-organisms that reduce yields of a major source of food–soybeans. In the United States alone, approximately $1 billion is lost per annum due to cyst nematode infections on soybean plants. Experts have conceived methods of mitigating the losses through phenotyping techniques via SCN eggs density estimation, and then applying the right control measures. Currently, they rely on labor intensive and time-consuming identification of SCN eggs in soil samples processed onto microscopic frames. However, phenotyping a vast array of fields requires automated high-throughput techniques. From an automation perspective, detection of rarely occurring ...

Field Experiments., James Atkinson

Bulletin (Iowa Agricultural Experiment Station)

The season of 1900 was an unusual one throughout. The large rainfall during the growing months was in most respects favorable to plant growth as indicated by the magnificent crops that were harvested, though for the best results in some forms of experimental work, a drier season is essential. For example, an experiment was undertaken to determine the effect of cutting clover in different stages of maturity upon the quantity and quality of the cured hay from two cuttings, but owing to the difficulty in curing on account of wet weather, the results were not ascertained. The favorable conditions of ...


The Asparagus Rust In Iowa., L. H. Pammel, E. R. Hodson 2017 Iowa State College

The Asparagus Rust In Iowa., L. H. Pammel, E. R. Hodson

Bulletin (Iowa Agricultural Experiment Station)

During the summer our attention was called to the appearance of Asparagus Rust on Muscatine Island by Mrs. Alice Walton Beatty. Early in September the rust was found in considerable quantities in one of the asparagus beds on the college farm; since then it has been observed at many points by ourselves and Mr. M. Cumming, in and about Ames. It was also reported to us from McBride, Iowa, by Mr. H. A. Mueller, in September, 1900, as being abundant at that place and at Mt. Pleasant by Mr. E. E. Hodson.


Winter Wheat., James Atkinson 2017 Iowa State College

Winter Wheat., James Atkinson

Bulletin (Iowa Agricultural Experiment Station)

There is a growing demand throughout the state of Iowa for information relating to the growing of winter wheat. This is explained by referring to crop statistics. In 1885 there were 56,854 acres of winter wheat grown in the state, as against 1,294,733 acres of spring wheat, while in 1898 there were 192,056 acres of the former and 1,226,510 acres of the latter. In other words, while the acreage of winter as compared with that of spring wheat was only one-twentieth in 1885, it had increased until it amounted to one-sixth in 1898. The ...
