Ecological Investigations Upon The Germination And Early Growth Of Forest Trees, Richard H. Boerker

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

Briefly stated the purpose of the present investigation is to inquire into the effect of the more important habitat and seed factors upon the germination and early development of certain American forest trees in control cultures in the greenhouse for the purpose of obtaining data that may be used in the ~ilvicultural management of these species.

Corn Silage And Alfalfa Hay For Beef Production, Ralph K. Bliss, C. B. Lee

University of Nebraska-Lincoln Extension: Historical Materials

SUMMARY.

1. A ration of corn and alfalfa hay produced the cheapest gains of any ration used. Furthermore, the steers fed corn and alfalfa hay made as rapid gains as did the steers on any other ration.
2. Had the alfalfa hay used in the first experiment cost $20 per ton, the average profit on the three lots receiving alfalfa would have been 15 per cent greater than the profit on the best one of the three lots not receiving alfalfa.
3. Cold pressed cottonseed cake did not give as good results, as regards either rate of gain or economy …

Summary Of Two Years' Study Of Insects In Relation To Pellagra, Allan H. Jennings

Harold W. Manter Laboratory of Parasitology: Library Materials

Excerpt:

With the growing interest in pellagra, following the authoritative recognition of its presence in the United States in 1907, the study of its etiology was taken up by various investigators and the several theories of causation were subjected to close scrutiny.

Prominent among these theories was that of insect transmission, first advanced by Sambon, who limited this function to the species of blood-sucking gnats comprising the genus Simulium.

The importance of the disease and the possibility of such a factor in its causation, led the Bureau of Entomology, late in 1911, to undertake an investigation of the subject …

Some Of The Next Steps In Botanical Science, Charles E. Bessey

School of Biological Sciences: Faculty Publications

When one who has worked long in any

field of science speaks before an audience

such as this he is expected to say something

about the condition of his branch of science

when he began work with meager and

poorly adapted apparatus, to contrast it

with its greatly improved condition to-day,

and to dwell with pride upon the finely

equipped laboratories with costly apparatus

especially designed for particular

experiments, to be found by the twentieth

century scientific student. And 1 must

confess that the temptation to do so was

one difficult to resist, for we who have

grown old in …

A Consideration Of The Physiology And Life History Of A Parasitic Botrytis On Pepper And Lettuce, George L. Peltier

Department of Plant Pathology: Faculty Publications

During the autumn of 1911, while gathering the peppers (Capsicum) in the vegetable plat of the Missouri Botanical Garden, the writer observed a fungus which was appearing as a parasite on the fruits. The peduncles were covered with a dark brown mass of conidia and mycelium, which so weakened the tissues that the fruit soon fell to the ground. On opening the peppers a number of large, flat, crust-like sclerotia, 1 cm. long and .5 cm. wide, were found to fill the interior. In most cases the seeds were also covered with the crust-like masses. The conidial stage …

Forage Crops For Hogs In Kansas And Oklahoma., C. E. Quinn

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

Farmers are more and more realizing that pasture is necessary for the most economical production of pork. Those who are raising hogs and putting them on the market with the least ·cost have their entire farms fenced" hog-tight." This enables them to give the hogs the range of the meadows and fields when the crops have been harvested. Much that would otherwise be lost is thus saved by the hogs, for they are among the best gleaners of waste grain, weed seeds, and insects in the fields.

Malarial Fever In Horses, A. T. Peters

University of Nebraska Historical Extension: Bulletin

This disease is also called "swamp fever" by farmers, and "pernicious anaemia" by veterinarians. In Nebraska many of the farmers call the disease "typhoid fever," for it resembles this fever very much. The manner in which the disease is contracted by horses is not definitely understood. In the last few years, the veterinarians in the Philippines have discovered a disease, prevalent in India under the name of "surra," the description of which corresponds very much to that of malarial fever of horses in this country, with the exception that bacteriologists have not been able to find the surra parasite in …

Cattle Feeding Experiment. Roughness Supplementary To Corn For Fattening Two-Year-Old Range Steers., H. R. Smith

University of Nebraska Historical Extension: Bulletin

In the economical production of beef, the character of the roughness fed in connection with corn is a factor of greater importance than we have given it in the past. Heretofore, 'the inclination among cattle feeders has been to depend almost entirely upon corn for producing beef, supplying almost any sort of roughness that would satisfy the craving of the animal for something bulky. Some, in fact, have operated upon the theory that in producing beef for the market it is desirable to feed corn as heavily as possible, discouraging the consumption of rough feed by supplying an inferior quality …

The Morphology Of The Pine Cone, Charles E. Bessey

Papers in Systematics and Biological Diversity

So much has been said in regard to the morphology of the cone of the pine and its near allies that it would seem impossible as well as unnecessary to suggest anything further. However, the recent excellent summary in Coulter and Chamberlain's “Morphology of the Spermatophytes" of the many theories hitherto advanced to clear up the matter, and the conclusions reached by the authors named, show that it is by no means settled, and perhaps warrant me in presenting an interpretation which I have used in lectures before my own classes for half a dozen years or more.

A Preliminary Report On Experiments With Forage Crops, T. L. Lyon

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A preliminary report on experiments with forage crops. Covers sorghum, cow pea, hairy vetch, Canada field pea, non-saccharine sorghums, soybean, and rye.

Summary

Permanent grass pastures may be successfully substituted by certain annual forage plants.

A quick-growing variety of sorghum affords pasture fully equal to native or cultivated grasses.

Sorghum has the advantage of affording more forage per acre, and in being green and succulent throughout the entire summer. Its disadvantage consists in the necessity of plowing land for each crop.

One acre of sorghum will furnish pasture for ten cows twelve days.

The most profitable time to pasture sorghum …
