The Relationship Of Applied Rock Phosphate On The Growth Of Sweet Corn, Deborah A. Sutherland
The Relationship Of Applied Rock Phosphate On The Growth Of Sweet Corn, Deborah A. Sutherland
Natural Resources Management and Environmental Sciences
Banding is a more intense application of fertilizers than broadcasting. Literature reviews have indicated that a higher amount of phosphorus in the root zone can enhance the growth and development of seedlings (Amin and Zaidi, 2004). Field trials on Sandy and Loam soils were conducted to test the effects of rock phosphate on sweet corn. These effects were investigated by studying the height, dry weight and phosphorus uptake of plants grown in soils banded with 0-90 lb P2O5/AFS. The results were moderate increases in plant height with applied rock phosphorus. The laboratory studies entailed oven drying forty day old corn …
Influence Of Prestress Environment On Annual Bluegrass Heat Tolerance, Dennis L. Martin, David J. Wehner
Influence Of Prestress Environment On Annual Bluegrass Heat Tolerance, Dennis L. Martin, David J. Wehner
Office of the Dean (CAFES) Scholarship
Annual bluegrass (Poa annua L.) turf quality is reduced during periods of high temperature. To predict heat stress injury and develop improved prestress maintenance practices, an understanding of the seasonal variation in annual bluegrass heat tolerance and the influence of soil moisture on heat tolerance is crucial. Annual bluegrass growing in the field on a Drummer silty clay loam (fine silty, mixed, mesic Typic Haplaquolls) was sampled on 23 dates over two growing seasons and brought to a laboratory for exposure to high temperature. Prestress environmental conditions (air and soil temperature, soil matric potential, plant water potential, daylength, rainfall and …
