Crop Selection, Cost Analysis, And Irrigation System Design For The Replanting Of A Nut Orchard, Maximilian Bricker Jun 2016

Crop Selection, Cost Analysis, And Irrigation System Design For The Replanting Of A Nut Orchard, Maximilian Bricker

BioResource and Agricultural Engineering

This report was made to help the landowner of Bricker Farms make decisions regarding the replanting of his orchard. The decisions that need to be made in this process include: which crop to plant, how to plant it, and how to improve the distribution uniformity of irrigation water on the orchard. The report does not give definitive final decisions, but presents viable options that the landowner can utilize when deciding. In addition to the options that are presented, the report offers suggestions to the landowner so that the replanting process is done properly in a timely and economically-friendly manner.


Influence Of Prestress Environment On Annual Bluegrass Heat Tolerance, Dennis L. Martin, David J. Wehner May 1987

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 …
