Nitrogen Content And Protein Yield Of Alfalfa As Influenced By Variety, William H. Bennett
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 …
The Emergence And Survival Of Certain Forage Plants When Seeded In A Saline Soil, Devere Richard Mcallister
The Emergence And Survival Of Certain Forage Plants When Seeded In A Saline Soil, Devere Richard Mcallister
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Salty soils are recognized as an ever increasing problem connected with irrigation agriculture. Millions have been spent by state, federal and private agencies on technical research in an attempt to solve this problem. Other millions have been spent on drainage projects, land leveling, field explorations and soil amendments attempting to alleviate the situation in the field.
Crop Response To Applications Of Copper Sulfate On Salty Soils, Paul D. Christensen
Crop Response To Applications Of Copper Sulfate On Salty Soils, Paul D. Christensen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In the arid west large areas of soil contain soluble salts in sufficient concentrations to inhabit crop growth. Of the 1,416,957 acres of soil surveyed in Utah from 1899 to 1920, Jennings et al (29) reported that 43.58 per cent contained 0.2 per cent or more of salts. The management and reclamation of these soils present serious problems. The difficulties are further accentuated by the fact that many streams used for irrigation contain appreciable quantities of salt. Generally under these conditions removal of the salt from the soil becomes impracticable, and the problem is one of learning how to get …
