Bulletin No. 113 - The Influence Of The Combined Harvester On The Value Of The Wheat, Robert Stewart, C. T. Hirst

UAES Bulletins

The extension of the dry-farming area in Utah and the bringing of many thousands of acres of virgin land under wheat cultivation, in large farms, has, in recent years, caused much improvement in the use of farm machinery. One great improvement has been the adoption of the Combined Harvester, which cuts, threshes and sacks the grain in one operation in the field at a minimum of cost. This has been an important factor in the success of the dry-farming movement.

Bulletin No. 111 - The Reclamation Of Seeped And Alkali Lands, C. F. Brown, R. A. Hart

UAES Bulletins

In the year 1905, Drainage Investigations were begun in the State of Utah by the Office of Experiment Stations of the United States Department of Agriculture, in co-operation with the Utah Experiment Station. Appropriations have been made by the Utah State Legislature for irrigation and drainage investigations on condition that the United 8tates Department of Agriculture contribute an equal amount, and that the work be conducted jointly by the Federal department and the experiment station of the Agricultural College of Utah.

Bulletin No. 109 - The Nitrogen And Humus Problem In Dry-Land Farming, Robert Stewart

UAES Bulletins

The effect of cultivation and the growth of crops upon the nitrogen and humus content of soils has been studied by various investigators, both in America and Europe. In general, the results of the various investigations indicate that cropping and cultivation are very destructive of the organic. matter and the nitrogen of the surface soil.

Bulletin No. 108 - The Effect Of Formalin On The Vitality Of Seed Grain, Robert Stewart, John Stephens

UAES Bulletins

The Utah Experiment Station for a number of years has recommended the formalin treatment for the prevention of smut in wheat, oats and barley. Since the publication of Bulletin No. 84 by Prof. L. A. Merrill on the Subject, a number of complaints regarding the treatment have been received. We learned, also, by traveling over the state, that these complaints were quite general. The work reported in this bulletin was undertaken for the purpose of throwing light on these questions, and it is hoped that the results obtained will be of value to the farmers of the state.

The Inheritance Of Sizes And Shapes In Plants, R. A. Emerson

Some years ago Lock reported a cross of a tall race of maize with a shorter race which produced an intermediate height in F₁ and exhibited no segregation in F₂ when crossed back with one of the parents. Castle's results with rabbits are very similar to those of Lock with maize. Castle summarizes his results in part as follows:

A cross between rabbits differing in ear-length produces offspring with ears of intermediate length, varying about the mean of the parental ear-lengths. . . . A study of the offspring of the primary cross-breds shows the blend of the …
