Bionomics Of Insects Associated With Corn In The Nebraska Sandhills, J. L. Wedberg, J. B. Campbell, T. J. Helms

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Investigations were conducted in the Nebraska Sandhills to determine the impact of transition from grassland to irrigated corn on selected insect species, to identify indigenous species that may be economically important to corn production, and to provide a point of reference for future development of pest management programs for irrigated corn.

Cultural Practices For Seed Production From Established Stands Of Western Wheatgrass, D. E. Smika, L. C. Newell

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Fertilization and irrigation requirements and aftermath removal practices for maximum seed production from solid stand western wheatgrass were studied for three years near Oakley, Kansas. Conclusions from this study indicate that to obtain maximum quantity of highest quality western wheatgrass seed from established stands, the grass must be fertilized in the fall with at least 80 pounds of nitrogen per acre. Irrigation with sufficient water to fill the root zone in either the fall or early spring and again when the grass is in " boot" or heading is necessary. The practice of removing the aftermath following harvest by mowing …

Irrigation And Fertilization Practices For Seed Production From Established Stands Of Side-Oats Grama, D. E. Smika, L. C. Newell

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The objectives of this study of grass seed production were to determine the response of an established stand of a warm-season grass to irrigation and fertilizer practices with regard to the specific practices needed to produce maximum quantity of adequate quality seed per acre. Side-oats grama was chosen for the study because of the availability of adapted varieties.

Performance Of Alfalfas Under Five Management Systems, W. R. Kehr, E. C. Conard, M. A. Alexander, F. G. Owen

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This bulletin reports stands, forage yields, and other agronomic data on alfalfas of diverse origin or type tested under five management systems at Lincoln, Nebraska. Narrow-crowned and broad-crowned types were tested. The management systems involved non-irrigated alfalfa-bromegrass tests (a) continuously grazed with steers, (b) cut for hay, and (c) rotationally grazed with sheep; an irrigated alfalfa-bromegrass test rotationally grazed with dairy cattle; and irrigated tests of alfalfas in pure stands cut for hay.

Reduced Ascorbic Acid Content Of Potatoes Grown With And Without Straw Mulching And Irrigation In Eastern Nebraska, H. O. Werner, Ruth M. Leverton, Mary R. Gram

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Potatoes harvested from home gardens and in commercial early-producing fields in the Midwest are an important low-cost source of ascorbic acid from late June into September. The major portion of the early commercial crop in Nebraska (harvested mostly in August) is produced with irrigation. Straw or litter mulching is a well established practice in the nonirrigated garden and farm potato patches. The value of these cultural methods for increasing yield is well known, but prior to this study little was known about their influence on the ascorbic acid content of the tubers, or about the persistence of any such influence …

Effect Of Cultural Methods And Maturity Upon The Seed Value Of Eastern Nebraska Potatoes, H. O. Werner

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Seed potatoes as good as northern stocks have been produced under a straw mulch in eastern Nebraska by experimenters and growers. Occasionally reports are heard that a lot of seed potatoes has been grown in eastern Nebraska by ordinary cultural methods for many years, apparently without loss of vigor or yielding capacity. In view of this situation it seemed advisable to investigate this problem to determine whether, and to what extent, environment and maturity as such influence the productivity of seed potatoes and also whether it is feasible to produce satisfactory seed potatoes in the southern and eastern portions of …

The Spindle-Tuber Disease As A Factor In Seed Potato Production, H. O. Werner

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The lines of experimentation that supplied the data herein reported, stated in very general terms, were as follows: (1) Tuber-line selection studies (2) Relation of environmental conditions to seed-potato production (3) Seed-potato strain trials of certified and uncertified stock (4) Spindle-tuber transmission experiments. Most of these general lines of experimentation will not be completely discussed as a unit in any one part of the bulletin. For the sake of clarity, consecutive thought, and elimination of repetition, data will be selected from any experiment for insertion and discussion under the most logical heading in any part of the bulletin. Unless otherwise …

Seed Potato Investigations, H. O. Werner, R. F. Howard

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The objects of the investigations reported in this bulletin were:

• To determine the condition of western Nebraska seed stock by the tuber unit method and by comparative trials in western Nebraska and various other points.
• To determine the effect of culture, place, disease, etc., upon seed value.
• To perfect methods of applying results to seed production in western Nebraska.
