The Influence Of Time And Rate Of Application Of Urea Spray On The Yield And Protein Content Of Winter Wheat, Vern L. Marble

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Winter wheat, with an annual average acreage of about 300,000 acres, forms an integral part of the farm economy of Utah.

For many years intermountain agronomists and farmers alike have known dry-land wheat production to be limited by low summer rainfall. In the past 15 years, however, it has become apparent through intelligent research that in many cases lack of nitrogen has been the limiting factor. When this occurs, winter wheat production can be increased by correcting this nitrogen deficiency

Nitrogen Content And Protein Yield Of Alfalfa As Influenced By Variety, William H. Bennett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Twenty-four alfalfa varieties, representing four varietal groups, were compared for nitrogen content and protein yield. A highly significant difference between varieties was noted for nitrogen content, and a significant difference for protein yield. Saskatchewan 666 had the highest content in the first cutting, but Ledak 22009 had the highest content in the third. Group differences were not significant. Crop differences were highly significant for nitrogen content, yield of forage, and of protein. In the case of every variety, the third cutting was richer in nitrogen than the second and the seemed was richer than the first. Protein yield, however, was …
