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 Nov 1951

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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 …

One Hundred Studies Of The Calcium, Phosphorus, Iron, And Nitrogen Metabolism And Requirement Of Young Women, Ruth M. Leverton, Alice G. Marsh Apr 1942

One Hundred Studies Of The Calcium, Phosphorus, Iron, And Nitrogen Metabolism And Requirement Of Young Women, Ruth M. Leverton, Alice G. Marsh

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present study was undertaken to add appreciably to the data available on the metabolism of calcium, phosphorus, iron, copper, and nitrogen of young women on their customary self-chosen diets. It was planned to use the figures for the retentions or losses of these dietary essentials which occurred at various levels of intake to determine the requirement of the subjects and to evaluate the adequacy of present adult dietary standards for young women. The fact that the girls were living on self-chosen diets warrants emphasis. A large proportion of the subjects were doing light housekeeping and brought much of their …
