Field Notes from Valerie Tate
One of our goals over the last few years has been to increase the
involvement of campus-based faculty in the research program at FSRC.
My primary responsibility is facilitating those projects. Following
is a list of the current research projects at FSRC involving campus-
based faculty.
Alfalfa Variety Trail - Dr. Rob Kallenbach
The objective is to evaluate the performance and persistence of alfalfa varieties.
Effect of Potassium Fertilization on Leafhopper Tolerance and Persistence of Alfalfa - Dr. Jerry Nelson
The objectives are to determine the effect of K fertilization on leafhopper tolerance, measure the effect of glandular hairs on leafhopper tolerance and evaluate the interaction of K fertilizer and glandular hairs on alfalfa persistence.
The Influence of Nitrogen Rate and Pasture Composition on Stockpiled Tall Fescue - Dr. Rob Kallenbach
The objectives are to determine the efficiency of a late summer application of nitrogen on tall fescue and tall fescue/red clover pastures used for stockpile forage, N effect on the ergovaline content of the forage and N effect on the red clover component of the pasture the following spring. Ergovaline is the primary toxin produced in endophyte infected tall fescue and its concentration has been shown to increase with higher N levels. We are also evaluating the change in ergovaline concentration over the winter.
Site Specific Phosphorus Management - Dr. John Lory
The objective is to measure the concentration of phosphorus in the soil in relation to the application of commercial fertilizer and poultry litter 30, 90 180 and 360 days after application.
Effect of Spring Nitrogen Application and Timing of Grass Hay Harvest on Forage Yield and Quality in Mid-August on a Tall Fescue-Annual Lespedeza Pasture. - Dr. Bob McGraw
The objective is to determine the effects of nitrogen rate and the timing of the initial hay harvest on annual lespedeza establishment, yield and quality in mid August in a tall fescue pasture. Hay is harvested at vegetative, boot, heading, and ripe seed growth stages.
Field Screening Low Endophyte Tall Fescue Germplasm for Persistence Under Grazing - Dr. Craig Roberts
The objective is the field screening and selection of tall fescue germplasm that contains no or low infection rates of the endophyte.
