Root Development Of Young Delicious Apple Trees As Affected By Soils And By Cultural Treatments, W. W. Yocum
Root Development Of Young Delicious Apple Trees As Affected By Soils And By Cultural Treatments, W. W. Yocum
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The major problem of this investigation was to determine the effects of different cultural treatments and soil conditions upon the depth and lateral spread of the root systems of young Delicious apple trees during the first three years in the orchard. This study was conducted during the years 1932 to 1934 inclusive.
The Utilization Of Food Elements By Growing Chicks. Iii. A Comparison Of Calcium Carbonate And Calcium Sulfate As Sources Of Calcium, C. W. Ackerson, M. J. Blish, F. E. Mussehl
The Utilization Of Food Elements By Growing Chicks. Iii. A Comparison Of Calcium Carbonate And Calcium Sulfate As Sources Of Calcium, C. W. Ackerson, M. J. Blish, F. E. Mussehl
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
I. The utilization of nitrogen, calcium, and phosphorus was studied with two lots of growing chicks by means of growth and body-analysis experiments. One lot had calcium added to the ration in the form of sulfate and the second received calcium carbonate, the additions being made on an equivalent calcium basis so that the experimental variable was the source of the calcium. 2. The percentage rate of gain and the gain per gram of nitrogen fed were identical in the two lots. 3. No significant differences were found in the utilization of nitrogen, calcium, or phosphorus by the birds of …

1. The effect of adding to a basal ration a protein concentrate consisting of meat scraps alone was compared with one made up of a mixture of meat scraps, fish meal, and dried buttermilk by means of growth and body-analysis experiments. 2. The percentages of nitrogen, calcium, and phosphorus contained in the chicks of the lot fed the mixture of three proteins were slightly higher than those found in the lot fed meat scraps as the concentrate. 3. The percentage rate of gain and the gain per gram of nitrogen fed were greater in the lot fed the mixture of …
Comparative Physiology Of Actinomyces In Relation To Potato Scab, Mitrofan M. Afanasiev
Comparative Physiology Of Actinomyces In Relation To Potato Scab, Mitrofan M. Afanasiev
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The present work was undertaken with the purpose of investigating the physiology of different strains of A. scabies as compared with saprophytic Actinomyces. By a comparative study of these groups, it was thought that differences in the physiology of the two might be found which would give a better understanding of the nature of this parasitism and also of the metabolism of Actinomyces in general. In addition, it was hoped that the determination of the factors influencing the parasitism of Actinomyces might establish a basis for the development of more efficient methods of controlling scab diseases. The present investigation …
The Influence Of Various Soil Factors Upon Potato Scab Caused By Actinomyces Scabies, R. W. Goss
The Influence Of Various Soil Factors Upon Potato Scab Caused By Actinomyces Scabies, R. W. Goss
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Scab, caused by Actinomyces scabies (Thaxt.) Giiss., is a potato disease of major importance in western Nebraska. Seed treatments are effective in controlling seed-borne scab, but it has been shown that even when healthy or treated seed potatoes are used the disease may be very severe because of infection from the soil. Crop rotation will reduce the incidence of the disease, but the fact that potato scab may cause serious loss in soils never before planted to potatoes indicates that there are numerous factors other than the time interval between potato crops which affect the occurrence of the disease. A …

The size of a dairy cow is important from the standpoint of feed consumption and economy of production and also as an indication of the expected size of offspring. The ultimate disposal of dairy cattle is for beef, and the measure of returns is based upon size and condition. A method for the determination of the approximate weights of dairy females, where scales are not available, is needed. Measurements of dairy cattle which show development and skeletal growth by ages in relationship to weight are presented here for four different dairy breeds.

Historical Research Bulletins of the Nebraska Agricultural Experiment Station
1. The effects of adding to a basal ration, protein concentrates from animal and vegetable sources were studied by means of growth and body-analysis experiments. 2. There was a small increase in the nitrogen content of the chicks fed the animal protein concentrate, but no differences appeared between lots with respect to their content of calcium and phosphorus. 3. The percentage rate of gain and the gain per gram of nitrogen fed were greater in the lot fed the animal protein concentrate. 4. The lot fed the animal protein concentrate retained more of the nitrogen fed, but less of the …
