The Utilization Of Food Elements By Growing Chicks. Viii. A Comparison Of Alfalfa Meal And Artificially Dried Sudan Grass Meal In Rations For Growing Chicks, C. W. Ackerson, M. J. Blish, F. E. Mussehl Dec 1939

The Utilization Of Food Elements By Growing Chicks. Viii. A Comparison Of Alfalfa Meal And Artificially Dried Sudan Grass Meal In Rations For Growing Chicks, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

1. The effect of replacing the ten parts of alfalfa meal in a ration with artificially dried Sudan-grass meal on an equivalent protein basis was studied in a growth and body-analysis experiment with two lots of day-old chicks. 2. The chicks of both lots consumed equal amounts of dry matter during the feeding trial. 3. There were no significant differences in the growth rate or composition of the chicks at the end of a six weeks' feeding trial.


Comparative Costs Of Home-Produced And Commercially Produced Bread And Rolls, Edna B. Snyder Oct 1939

Comparative Costs Of Home-Produced And Commercially Produced Bread And Rolls, Edna B. Snyder

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The purpose of this study was to determine the comparative costs of home-produced and commercially produced white and whole-wheat bread and rolls. Costs of home-produced bread were estimated on the basis of cost of ingredients and fuel, plus time. These costs were compared to costs of commercially prepared bread available at retail. Nutritive value was considered in interpreting results. The method used was a combination of survey and laboratory investigation. The survey included: (1) information regarding the baking practice of families in Nebraska, (2) detailed records of amounts and costs of ingredients, fuels, and time used in home-produced bread, (3) …


Personality Development In Farm, Small-Town, And City Children, Leland H. Stott Aug 1939

Personality Development In Farm, Small-Town, And City Children, Leland H. Stott

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

One purpose of the present research project was to contribute further toward an adequate knowledge of the relative merits of urban and rural environments. In this bulletin the three general home settings already mentioned, namely the farm in the open country, the small town (600 to 1,300 in population), and the city, are compared as to their "favorableness" in regard to the personality development of the children who grow up in them. The data for the comparisons are the average scores made by representative samples of young people from each environment on a set of tests and scales designed to …


Effect Of Organic Matter Decomposition On The Solubility And Fixation Of Phosphorus In Alkaline Soils, H. F. Rhoades Jun 1939

Effect Of Organic Matter Decomposition On The Solubility And Fixation Of Phosphorus In Alkaline Soils, H. F. Rhoades

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

It is the purpose of this bulletin to report a laboratory study on the effects of organic matter decomposition on the solubility and fixation of phosphorus in alkaline soils. The study included the following: (1) a comparison of the effects of a decomposing organic material with those of a physiologically acid nitrogen fertilizer, and (2) a comparison of the effects of different organic materials of varying phosphorus contents.


Effect Of Soil Type, Slope, And Surface Conditions On Intake Of Water, F. L. Duley, L. L. Kelly May 1939

Effect Of Soil Type, Slope, And Surface Conditions On Intake Of Water, F. L. Duley, L. L. Kelly

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

In connection with investigations of runoff and erosion in the Great Plains an attempt has been made by means of artificial applications of water to determine certain principles concerning the effect of different soils and soil conditions on runoff and soil erosion. Such information is needed in planning all field operations dealing with soil erosion and moisture control. It is also needed in connection with watershed studies that are being established in the Central Great Plains, dealing with runoff and flood flows from larger areas. The method employed makes it possible to obtain comparable data on a wide range of …


Further Studies Of Selected Types Of Domestic Gas Stoves, Arnold E. Baragar Apr 1939

Further Studies Of Selected Types Of Domestic Gas Stoves, Arnold E. Baragar

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This bulletin is a supplement to Nebraska Agricultural Experiment Station Research Bulletin 86. Tests were conducted in the same manner as were those described in Bulletin 86; hence, no reference has been made to experimental methods unless a test has not been previously reported. This paper is primarily concerned with (1) a discussion of cooking tops producing excessive carbon-monoxide gas, (2) more data relative to cooking-top burner efficiencies, (3) a further discussion of automatic lighters, and (4) a detailed study of ovens.


The Effects Of Stinking Smut (Bunt) And Seed Treatment Upon The Yield Of Winter Wheat, T. A. Kiesselbach, W. E. Lyness Apr 1939

The Effects Of Stinking Smut (Bunt) And Seed Treatment Upon The Yield Of Winter Wheat, T. A. Kiesselbach, W. E. Lyness

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The depreciating effects of bunt or stinking smut (Tilletia levis Kuhn and tritici [Bjerk.] Wint.) upon the yield and quality of winter wheat in Nebraska and many other states are well known. The practical control of this disease through seed treatment has also been established and is being extensively practiced by growers. At the time these experiments were initiated in 1923, formaldehyde was the most commonly used disinfectant, while copper carbonate was just gaining recognition following its introduction by Darnell-Smith in 1915. It has been the chief purpose of the investigations herein reported to study the relative merits of …


The Utilization Of Food Elements By Growing Chicks. Vii. A Comparison Of Corn And Kalo In A Ration For Growing Chicks, C. W. Ackerson, M. J. Blish, F. E. Mussehl Mar 1939

The Utilization Of Food Elements By Growing Chicks. Vii. A Comparison Of Corn And Kalo In A Ration For Growing Chicks, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

1. The effect of replacing 31 per cent of ground corn in a ration by 31 per cent of ground kalo was studied in a growth and body-analysis experiment with two lots of newly hatched chicks. 2. The amounts of feed consumed by all chicks of both lots were kept identical by hand-feeding equal amounts of the pelleted rations daily. 3. There were no significant differences in the growth rate or composition of the chicks at the end of a six weeks' feeding trial.


The Utilization Of Food Elements By Growing Chicks. Vi. The Influence Of The Protein Level Of The Ration On The Growth Of Chicks, C. W. Ackerson, M. J. Blish, F. E. Mussehl Feb 1939

The Utilization Of Food Elements By Growing Chicks. Vi. The Influence Of The Protein Level Of The Ration On The Growth Of Chicks, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

1. Two rations containing 16 and 22 per cent of protein respectively were fed to newly hatched chicks in two series of feeding trials. In one series the lower protein level was secured by diluting the higher with 30 parts of starch so that the amount but not the quality of the protein was changed. In the other series the amount and quality of the protein both varied since the two rations were mixed by using different proportions of the base and concentrate to yield the 16 and 22 per cent levels in the finished rations. 2. Comparisons were made …
