Malting Barley Variety Trial 2017 Results

Malting Barley Variety Trial 2017 Results (PDF)

Ellen Mallory and Tom Molloy, University of Maine Cooperative Extension

Twenty five varieties of two- and six-row spring malting barley were trialed at two locations in Maine in 2017 (Table 1).  The trials were conducted in collaboration with 9 other institutions as part of the Eastern Spring Barley Nursery project (ESBN), organized by North Dakota State University and funded in part by the Brewers Association.

METHODS

The trials were conducted at the University of Maine Rogers Research Farm, in Old Town, and the Aroostook Research Farm, in Presque Isle. Agronomic practices for both locations are described in Table 2. Agronomic and basic grain quality data were collected by the University of Maine and grain samples were submitted to North Dakota State University for comprehensive grain and malt quality analysis.

Weed Control Tine harrow, May 25 MCPA Rhomene – 0.75 pt/acre & Harmony – 1 oz/acre, July 14
Harvest Date August 3 September 15

RESULTS

Yields were lower in 2017 than in the previous two years of the Maine EBSN trials. Site averages were 75 bu/acre in Old Town and 67 bu/acre in Presque Isle (Table 3), as compared with 109 and 95 bu/acre in 2016, respectively.  Wet weather during emergence in Old Town and delayed planting in Presque Isle contributed to lower yields.  The highest yielding varieties at both locations were KWS Tinka, Esma, AAC Synergy, and Explorer, while the lowest yielding variety was Pinnacle, which experienced early and severe foliar disease pressure.

Grain moisture at the Old Town location (Table 3) averaged 14.1% and was uniform across varieties with the exception of 2ND33821 which was at 19.3%.  Foliar diseases were moderate at both locations with the exception of Pinnacle.

Grain quality data is summarized in Table 4. Of note:

  • DON levels were low for all varieties at both sites this year.
  • Sprout damage, as measured using RVA, was minimal with only three varieties, LCS Odyssey, KWS Tinka and AAC Synergy showing moderate sprout damage.
  • Germination energy (GE) was high at the Old Town location, averaging 97%, but a few varieties still had GEs below the 95% optimal level. In contrast, in Presque Isle site, where average GE was 87%, many varieties had good GEs. Newdale performed poorly at this site.
  • Protein levels in Old Town were low, averaging 8.3%, and have been consistently low in prior years. AT this site, manure is applied at a rate to supply approximated 60 pounds of available N per acre. In the future, we plan to either increase the manure rate or topdress additional N.

Malt quality results are forthcoming.

† Thousand kernel weight.
‡ Deoxynivalenol (DON) is a mycotoxin caused by Fusarium head blight.
§ Protein is reported on a dry matter basis. Acceptable range is 9.5-12.5%.
≠ Kernel plumpness is measured as the percentage of barley that remains on top of a 6/64” by 3/4” slotted sieve after shaking.
# Rapid Visco-Analyzer (RVA) indicator pre-harvest sprout damage. Samples with RVA>120 are considered sound with high probability of maintaining germination energy in storage.  Values below this level indicate sprout damage with severity increasing as values decrease.
¥ Germination energy is the percentage of kernels that germinate over 3 days under controlled moisture and temperature conditions. >95% is considered acceptable.
