The Phytogeography Of Nebraska, Roscoe Pound, Frederic E. Clements Jul 1898

The Phytogeography Of Nebraska, Roscoe Pound, Frederic E. Clements

Papers in Systematics and Biological Diversity

From the preface we learn that this work is the result of nearly five years of active study of the floral covering of Nebraska, carried on by the members of the Botanical Seminar in the Botanical Survey of the State of Nebraska. The systematic study of the vegetation of Nebraska was begun by Dr. Bessey in 1884, and has since been carried on by him and his students, all previous collecting having been more or less desultory and unreliable. The Botanical Survey was organized in 1892, and its work has been directed to the collecting of specimens and observations for …

Bulletin No. 56 - Field Experiments With Wheat, Oats, And Barley, Lewis A. Merrill Apr 1898

Bulletin No. 56 - Field Experiments With Wheat, Oats, And Barley, Lewis A. Merrill

UAES Bulletins

The testing of varieties is by no means the most important work of the Station. It, however, has its value in bringing into the State [Utah], and acclimating, new varieties that may be suited to our conditions better than any now grown. The results reached in these tests ought to receive the careful attention of our farmers, because success in raising cereals depends upon securing the varieties best suited to our purpose, and in growing those in greatest demand.

The experiments recorded in the following pages give the results of variety tests with wheat, oats and barley, and, in addition, …


A Preliminary Report On Experiments With Forage Crops, T. L. Lyon Mar 1898

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 …


Bulletin No. 55 - Orchard Pests, U. P. Hendrick Mar 1898

Bulletin No. 55 - Orchard Pests, U. P. Hendrick

UAES Bulletins

While great advancement is being made in knowledge and treatment of orchard pests, yet the fruit growers of Utah still need and ask for information regarding the common pests found in their orchards. To supply this need is what this Bulletin attempts to do--to bring together in brief and practical form the present knowledge of the common orchard pests of Utah.


Bulletin No. 53 - Utah Sugar Beets (1897), John A. Widtsoe Feb 1898

Bulletin No. 53 - Utah Sugar Beets (1897), John A. Widtsoe

UAES Bulletins

Although the success of the Utah Sugar Co. has proved that sugar beets can be raised profitably in Utah, the farmer of the State, as well as others who are interested in the erection of sugar factories, desire a more accurate knowledge of the possibilities of the sugar beet in the various parts of the State, than can be obtained from isolated and uncontrolled tests. The Utah Experiment Station carried on, therefore, during the season of 1897, a co-operative sugar beet experiment with the farmers of Utah.

Observations Of The Adaptation Of The Leaves Of Kalmia Latifolia To Environment, Grace Ellen Wilson Jan 1898

Observations Of The Adaptation Of The Leaves Of Kalmia Latifolia To Environment, Grace Ellen Wilson

Student and Lippitt Prize Essays

Samples taken from the plant for observation are from two different locations (high dry land with full sun/low moisture and a swamp) and show that the leaves of the plant flourish more in sunlight than in dark, swamp areas.


Phylogeny And Taxonomy Of The Angiosperms, Charles E. Bessey Sep 1897

Phylogeny And Taxonomy Of The Angiosperms, Charles E. Bessey

Papers in Systematics and Biological Diversity

It is unnecessary for me to state at the outset what is evident to every botanist, that it is as yet impossible to present a complete phylogeny of the angiosperms. Phytopaleontology is too young a science, and the materials with which it deals are yet far too scanty to have given us direct evidence as to the phylogeny of all families of plants. No one can trace with great certainty from the fossil remains of plants yet discovered the genealogy of any considerable portion of the vegetable kingdom. It will be many a year before the direct evidence we so …

Bulletin No. 46 - Earthen Dams, Samuel Fortier Nov 1896

Bulletin No. 46 - Earthen Dams, Samuel Fortier

UAES Bulletins

According to the last census, 92 1/2 per cent of the Utah farms are irrigated. The advancement of agriculture in this State mainly depends upon the water, the available supply of which, in many of the older settled localities of the State, is already wholly utilized during the irrigation period. The future reclamation of new lands in such localities must, therefore, wait on the development of new sources of supply from storage reservoirs, sub-surface supplies, or from a more economical use of the summer flow of the available streams.

From estimates and measurements made by the hydrographers. of the United …

The Earliest Name For Steller's Sea Cow And Dugong, Theodore S. Palmer Oct 1895

The Earliest Name For Steller's Sea Cow And Dugong, Theodore S. Palmer

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

In 1811, Illiger published a number of new genera, proposing among others, Rytina for the sea cow of Bering Island and Halicore for the dugong of the Indian Ocean. Nearly all recent writers on mammals have adopted these genera, apparently overlook ing the fact that both animals had been named before 1811. As early as 1794 Retzius described the sea cow in the 'Handlingar' of the Stockholm Academy of Science, placing it in a new genus which he called Hydrodamalis, and the species, based on the Vacca marina of Steller, Hydrodamalis stelleri. The generic description is sufficient to …

Report Of A Botanical Exploration Of The Sand-Hill Region Of Central Nebraska Made In The Summer Of 1893, Per Axel Rydberg Jun 1895

Report Of A Botanical Exploration Of The Sand-Hill Region Of Central Nebraska Made In The Summer Of 1893, Per Axel Rydberg

School of Biological Sciences: Dissertations, Theses, and Student Research

Rydberg (1860–1931) was born Sweden and emigrated to the United States in 1882, first to mining camps in upper Michigan and eventually to Wahoo, in Saunders County, Nebraska, where he taught mathematics from 1884 to 1893 at now defunct Luther Academy. In the summers of 1891-1893, 1895, and 1896 he was a field agent for the United States Department of Agriculture and collected plants in Nebraska, South Dakota, Montana, Idaho, Wyoming, and Colorado, and specimens from those and other trips are in the Bessey Herbarium at the University of Nebraska–Lincoln, which house what is now known as the Charles E. …

Bulletin No. 35 - Steer Feeding, A. A. Mills Aug 1894

Bulletin No. 35 - Steer Feeding, A. A. Mills

UAES Bulletins

The object of this Bulletin is to give and discuss the results of experiments, herein detailed, in regard to the system, prevalent here, "of keeping cattle on hay and other coarse foods during the winter, then feeding grain for a few weeks in the spring just previous to selling. All over the inter-mountain region very little grain is fed, and what little is used is fed with the idea that an animal which has been kept poorly can be filled up with profit in a very short period, just before selling. The idea was to test these questions, and to …


Bulletin No. 34 - Relative Value Of Wheat, Peas, Corn And Barley In The Production Of Pork, A. A. Mills Jul 1894

Bulletin No. 31 - Time To Harvest Lucerne. Mulching., J. W. Sanborn Jun 1894

Bulletin No. 31 - Time To Harvest Lucerne. Mulching., J. W. Sanborn

UAES Bulletins

The opinion has prevailed in scientific as well as in practical circles, that hay cut before or during bloom is more valuable, pound for pound, than when cut at a later period, and it is even maintained that the gross product per acre is more valuable. The old assumption, now somewhat modified, that as plants mature a part of the starch and sugar is converted into fibre, and that the nutrition of the stem is moved into the seed, led to the belief that early-cut hay was both more digestible and more valuable than that cut at a later period. …


Bulletin No. 33 - 1. Grazing Values Of Varieties Of Grass. 2. Drilling Vs. Broadcasting Grass Seed., J. W. Sanborn Jun 1894

Bulletin No. 33 - 1. Grazing Values Of Varieties Of Grass. 2. Drilling Vs. Broadcasting Grass Seed., J. W. Sanborn

UAES Bulletins

In the annual report for 1893, we published the result of experiments in grazing nine varieties of grass and clover, plus the grazing value of a plat of all these varieties mixed. There were some unequal conditions in the trial and it was continued over until the present season.

On May 23, two steers were placed upon each of the ten lots, enclosed by wire fence, to remain there for the period of one month, in artier to observe the length of time the varieties would carry these steers and the growth derived from the varieties. Several reasons prevented the …


Bulletin No. 29 - Irrigation: Amount Of Water To Use. Relative Feeding Values Of Timothy, Lucerne And Wild Hay, J. W. Sanborn May 1894

Bulletin No. 29 - Irrigation: Amount Of Water To Use. Relative Feeding Values Of Timothy, Lucerne And Wild Hay, J. W. Sanborn

UAES Bulletins

In Bulletin 24 are given results of the first three years of experimentation as to the relation between the amount of water used and crop yield, soil fertility, and the exit, through drains, of the matters held in solution in the water applied. In this report are included the results of the first three years, plus those of the past season. The experiment is regarded of the very highest importance in that it deals with the right amount of water essential to the growth of wheat and grass crops, but more especially as it approximately determines whether the materials of …

Furthermore, the relation of exercise to the economical use of food is treated of. This Bulletin only reports the continuation of the experiment, as enlarged, carried on during the summer of 1892, and reported in Bulletin No. 22 of this Station.


Bulletin No. 27 - Irrigation; Early, Late And Usual, J. W. Sanborn Mar 1894

Bulletin No. 27 - Irrigation; Early, Late And Usual, J. W. Sanborn

UAES Bulletins

Bulletin No. 23 reported the results of the first three years' trials in early and late irrigation. The trial reported in this Bulletin is a continuation of the trials reported in the Bulletin. above mentioned. The purpose of the experiment is to ascertain whether water added to the soil very early is so far stored that it will be available later in the season, and whether late irrigation has an injurious effect on the crop through its influence on development of stem and leaf at the expense of the seed; or, again, whether it is necessary to irrigate crops later …

Bulletin No. 26 - Sub-Irrigation Vs. Surface Irrigation And Water For Irrigation, J. W. Sanborn, Samuel Fortier Dec 1893

Bulletin No. 26 - Sub-Irrigation Vs. Surface Irrigation And Water For Irrigation, J. W. Sanborn, Samuel Fortier

UAES Bulletins

It has long been held that irrigation water applied beneath the surface is better than surface irrigation, in relation to the amount used, the temperature of the soil, the amount of evaporation, washing of soil and yield of crop, including quality of crop received. Though philosophically there would seem to be little doubt that the propositions are well taken, sub-irrigation as an economical process has been over-pres ed by some as a mean of very greatly curtailing the amount of water used . There are those who have asserted that only one-tenth of the water applied by sub-irrigation would be …


Bulletin No. 25 - Fuits And Forest, Shade Adn Ornamental Trees, E. S. Richman Oct 1893

Bulletin No. 25 - Fuits And Forest, Shade Adn Ornamental Trees, E. S. Richman

UAES Bulletins

After three years' trial on the experimental grounds we are ready to acknowledge the conditions unfavorable to the growth of strawberries; the high and dry location of the land, coupled with its sterility, make it unsuitable to the growth of strawberries. The first plants were necessarily, on account of lack of time, planted before the soil was fertilized. Manure was applied freely the second and third seasons, as a top dressing, but the ground, being compacted by frequent irrigation, never has been in the proper condition for strawberries, either as regards fertility or mechanical condition. A new bed has been …
