Thank you to all the companies who have generously supported and participated in the 2018 University of Delaware small grains trials. Appreciation and gratitude is extended to the following cooperators who generously provided land and support for our off-site locations; Craig Murray (Murray Bros. Farm) of Selbyville; John Thomas of Thomas Family Farm in Marydel; and Rob Emerson of Emerson Farms in Middletown. Thank you to the farm staff at the UD Thurman Adams Research Farm; Brian Hearn (Farm Manager), Ward Harris, William Hawkins, Kyle Mitchell, George Willey, and Gunnar Isaacs for their help in maintaining equipment and plots. The variety trial program could not be done without any of them.
Wheat Summary
I have provided daily temperature and rainfall summary for Georgetown, De. In a separate file. This summary was compiled from data provided by Iteris Clear Ag. For more specific weather data, the Delaware Environmental Observatory System (DEOS) is recommended Delmarva had historic rainfall in May that impacted the wheat crop. See Chart below:
Lodging notes were taken, however, there was no significant lodging in any of the plots or locations. Plant heights were recorded for most of the locations. Heading dates were recorded only at Georgetown for logistical reasons.
Planting rates were 1.5 million seeds/acre (35 seeds/ft2). Planting was done with an Almaco research plot planter. Seed was drilled on 7.5” row spacing. Plots consisted of 9 rows and final plot harvest was 17 feet. Harvest was done with a Kincaid MF-8XP combine using a Harvestmaster grain gauge data collection system. Data collected at harvest was plot weight, test weight, and grain moisture. Yield data was corrected to 13.8% moisture for final report.
Planting and harvest dates are recorded in the summary for each location.
Fertility: All plots were fertilized with N-sul (27-0-0-6) in two split applications in late winter and spring for a total of 100 lbs. in the spring. 30 lbs of nitrogen was applied in the fall.
Herbicide: Harmony Extra @.9 ounce/A. This was applied with the second nitrogen application.
Fungicide: All plots were sprayed with Prosaro fungicide.

Barley Summary
We conducted two separate barley trials in 2018, both located at Georgetown. Companies submitted both malting and grain varieties for testing. All of the varieties were tested together. The fertilizer program was the same as we have been using in previous years (split applications totaling approximately 100 lbs. N.). A fungicide was used to reduce disease pressure and maintain high quality at harvest.
Grain samples are being analyzed post-harvest by Michigan State and results will be posted. Field notes, planting dates etc. are included in the barley report.
