The Storage And Use Of Soil Moisture. Report Of Experimental Substation, North Platte, Nebraska, W. W. Burr

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The profitable cultivation of the non-irrigable lands in west central and western Nebraska is limited by the amount and efficient use of the precipitation. There are tracts of land in the sand hills and minor tracts of badly worn heavier soils where the need of soil fertility is becoming evident. But, in the main, the great problem at present is not one of soil fertility, but of how to get enough water to make use of the fertility now present. The rainfall of this section, which varies from an actual shortage to seldom more than a meager sufficiency, makes it …

Bulletin No. 133 - Irrigation And Manuring Studies: The Effect Of Varying Quantities Of Irrigation Water And Manure On The Growth And Yield Of Corn, Frank S. Harris

UAES Bulletins

Indian corn is one of the most important crops raised by American farmers. Anything that affects the corn crop of the American farmers. Anything that affects the corn crop of the United States has an influence on the prosperity of the entire country. From an economic point of view therefore, it is important to know as much about the production of this crop as possible. The corn plant also offers an excellent field for scientific investigation independent of any economic bearing.

Circular No. 17 - The Number And Distribution Of Licensed Stallions And Jacks In The State In 1913, W. E. Carroll

UAES Circulars

Table No. 1 shows the number of licensed stallions and jacks of each breed in each county of the State. It will be seen that 439 licenses have been issued. Of these 92 are grades, which means that 79 per cent of all the licensed animals of the State are purebred. Cache County leads with 59 licensed animals, including 8 grades. Sevier County stands second with 51, including 8 grade animals. Sanpete County has 43 licensed animals, including 10 grades. Utah County has 44, two of which are grades. The number of licensed animals vary in the other counties from …

Bulletin No. 131 - Variety Tests Of Field Crops In Utah, Frank S. Harris, J. C. Hogenson

UAES Bulletins

The number of varieties of practically all the field crops is now very great, and is increasing every year. Each variety has certain growers who believe in it and who do what they can to make it more widely grown. As a result many varieties of crops are found in most every farming community.

This condition is often bad, since it is impossible to build up a good market with a great mixture of varieties of any crop. A much better price can be obtained if each community offers for sale large quantities of a few standard types, rather than …

Circular No. 16 - Better Seed, Frank S. Harris

UAES Circulars

It is impossible to produce good crops unless good seed is used. The soil may be of the best quality and it may be prepared in the most thorough manner, the supply of moisture may be ample, the season may be the most favorable, yet all these count for little if worthless seed is planted.

Bulletin No. 132 - Minor Dry Land Crops At The Nephi Experiment Farm, P. V. Cardon

UAES Bulletins

The investigations conducted at the Nephi substation deal primarily with cereals; other crops, such as alfalfa, peas, corn, potatoes, etc., have occupied only a secondary position in the work of this station. This necessarily has been true because the experiments are confined to dry-land practices, and the cereals unquestionably comprise the basal crops for dry-land farming as it is now understood and practiced in Utah. No crops have been found as yet which yield so profitably on the dry lands as do the cereals, especially winter varieties.

The purpose of this bulletin is to review the work done on the …

The Inheritance Of A Recurring Somatic Variation In Variegated Ears Of Maize, R. A. Emerson

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The inheritance of variegation has special interest and importance in genetics. In this paper I shall present data from maize and attempt to show how they can be interpreted in strictly Mendelian terms.

Bulletin No. 130 - The Change In Weight Of Grain In Arid Regions During Storage, Frank S. Harris, George Thomas

UAES Bulletins

In handling grain the question of the changes that may occur in weight after threshing is always before the dealer. If there is any considerable loss during storage his profits are consumed, while if there is a gain it is possible for him to work on a much closer margin.

The Inheritance Of A Recurring Somatic Variation In Variegated Ears Of Maize, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

The inheritance of variegation has special interest and importance in genetics. It is with forms of variegation that the only two certainly known cases of non-Mendelian inheritance have had to do. I refer to Baur's experiments with Pelargonium, in which crosses of green-leaved and white-leaved forms exhibited somatic segregations in F₁ that bred true in later generations, and to Correns 's work with Mirabilis, which showed green and white leaf color, to be inherited through the mother only. De Vries's con- ception of "ever-sporting" varieties was apparently founded largely upon the behavior of variegated flowers in pedigree …

Multiple Factors Vs. "Golden Mean" In Size Inheritance, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

Groth's preliminary note on the "golden mean" in the inheritance of sizes in SCIENCE of April 17, 1914, pp. 581-584, deserves the attention of geneticists. Its publication is of such recent date that I need only call attention to one or two points that seem to me of particular moment.

In brief, Groth's hypothesis is that the mode

of inheritance in F_l not only of surfaces and

volumes, but also of linear dimensions is to be

expressed by √ab rather than by a + b /2

where a and b are parent sizes. The hypothesis

is based upon …

Rocky Mountain Flowers, Frederic E. Clements, Edith Schwartz Clements

School of Biological Sciences: Faculty Publications

AN ILLUSTRATED GUIDE FOR PLANT-LOVERS AND PLANT-USERS WITH TWENTY-FIVE PLATES IN COLOR AND TWENTY-TWO PLATES IN BLACK AND WHITE

The present book is an endeavor to present the materials of the Rocky Mountain flora in preliminary form from the standpoint of the experimental ecologist. The latter is concerned primarily with the relationships of "species" and their subdivisions as an organic expression or measure of habitat differences, and of the competitive relations of the various formations. Whatever the taxonomic value of the numerous segregates of the last decade or two, the fact that the binomial form conceals the relationship to the …
