Progressive Development And Seasonal Variations Of The Corn Crop, T. A. Kiesselbach
Progressive Development And Seasonal Variations Of The Corn Crop, T. A. Kiesselbach
Nebraska Agricultural Experiment Station: Historical Research Bulletins
The chief purpose of these studies has been to determine the normal growth changes that occur in the corn plant at successive intervals when growing in the field, and to observe annual yield variations in relation to prevailing weather conditions. Aside from supplying information regarding the physiology of this crop, the data are of interest to the corn grower because they indicate comparative yields, shelling percentages, moisture contents, and feed constituents at various stages of development. Some data also are presented concerning the effects of frost, drouth, day length, and the economic value of tillers and seminal roots.

Aircraft In Agriculture, N. E. Shafer, J. D. Furrer, J. W. Lomax
Nebraska Agricultural Experiment Station: Historical Circulars
Airplanes were first used in agriculture shortly after the close of World War I. They proved valuable for locating mosquito breeding areas, for forest fire patrol work, as an aid in locating outlaw cotton fields in the campaign against pink bollworm, and for surveying damage caused in large forested areas by the spruce budworm.
The Influence Of Crop Plants On Those Which Follow V, Theodore Eugene Odland, Robert Smith Bell, John B. Smith
The Influence Of Crop Plants On Those Which Follow V, Theodore Eugene Odland, Robert Smith Bell, John B. Smith

This is a study of the effect which crop plants have on the growth and yields of those crops which follow. The study began in 1907; this bulletin reports the results from 1930 to 1942. Millet, mangels and rutabagas generally seem to be harmful to crops which follow them. Carrots, mangels and millet were least favorable of all crops to mangels. Potatoes did poorest when following potatoes, rutabagas, or millet. Rutabagas yielded low following rutabagas, mangels and millet. Onions were unfavorably affect by preceding crops of mangels, cabbage, or rutabagas. There is no simple explanation for the effect of crops …
Inheritance Of Resistance To Races Of Covered Smut, Awns, And Chaff Color In A Wheat Cross, Nazar Singh Dhesi
Inheritance Of Resistance To Races Of Covered Smut, Awns, And Chaff Color In A Wheat Cross, Nazar Singh Dhesi
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Wheat is the most important cereal crop in the world. It is the principal staple food in Russia, United States, China, Canada, India and a number of other countries.
Covered smut is one of the most serious disease of wheat all over the world. According to Woolman and Humphrey (82) it was known from very early times and is referred to by Theoprastus and other early Greek Roman writers.
Inheritance Of Resistance To Six Races Of Bunt, To Awns And Kernel Color In A Wheat Cross, Marr D. Simons
Inheritance Of Resistance To Six Races Of Bunt, To Awns And Kernel Color In A Wheat Cross, Marr D. Simons
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Wheat is the most important cereal crop of the world, and one of the most serious diseases affecting it over much of its range is covered smut or bunt (57). The word "bunt", according to Heald (48), is a contraction of an old English term, "burnt ear", which fittingly describes the ravages of covered smut.
Man's first knowledge of this disease is lost in antiquity, but it was first recorded by early Greek writers (97). Gaines (39), writing in 1928, stated that since 1924 stinking smut had been the most destructive parasite of wheat in America, causing losses of as …

Microorganisms And Soil Structure, T. M. Mccalla

SUMMARY
Laboratory tests were made to determine the effectiveness of different compounds and microbial groups in increasing the stability of Peorian loess lumps against the action of falling water drops. The influence of these on percolation tests in the laboratory was also determined.
Many organic substances-dextrose, sucrose, starch, peptone, cullulose, and gum arabic-did not themselves contribute directly to soil-structure stability, though these substances do furnish energy material for soil microorganisms, which can convert them readily into either microbial tissue or decomposition products that increase soil-structure stability. Lignin, proteins, oils, fats, waxes, resin, and paraffin increased the stability of lumps of …
Safflower Production In The Western Part Of The Northern Great Plains, C. E. Classen
Safflower Production In The Western Part Of The Northern Great Plains, C. E. Classen
Nebraska Agricultural Experiment Station: Historical Circulars
Recent development of new varieties with seeds averaging more than 30 per cent oil give safflower a good chance of becoming an important oil seed crop in the United States. It is the purpose of this circular to acquaint farmers with the crop and to outline the most promising production practices for those who undertake its production in the western part of the northern Great Plains.
