Yield Contest

 

It’s about more than bragging rights. It’s about discovering varieties and management choices that work for soybean growers in Delaware.

Insights after Five Years

A closer look at the production methods, as viewed by Phillip Sylvester, UD Cooperative Extension agent, Kent County.

There were 67 entries in the Delaware soybean yield contest from 2012-2016. Forty-three were entered as full season soybeans while the remaining 24 were double-cropped after a small grain crop.

  • Over 93% of the full season soybean entries were irrigated with an average yield of 67.4 bu/A compared to the non-irrigated average yield of 65.4 bu/A.
  • Eighty-three percent of the double crop entries were irrigated with an average yield of 62.9 bu/A compared to the non-irrigated entries, which yielded 47 bu/A.
  • All the contestants used the herbicide Roundup (active ingredient: glyphosate).
  • The majority (72%) used a cover crop in the full season entries, with rye being the most popular followed by wheat, barley, triticale, and hairy vetch.
  • 30” row spacing was the most common (49%) in the full season entries with an average yield of 66.8 bu/A followed by 15” (40%) at 67.6 bu/A, and drilled (row spacing less than 8”) (11%) at 68.3 bu/A. The 15” row spacing was most common in the double crop entries (67%) with an average yield of 60.9 bu/A followed by 30” (29%) at 57.7 bu/A while only one contestant used a row spacing less than 8” with a yield of 66.8 bu/A.
  • Over the past five years, 100% of the winners in the full season category planted in May while 75% of the winners planted double crop beans in June.
  • In 2016, the winning full season soybeans were (80.74 bu/A) planted at 140,000 seeds per acre compared to 148,000 seeds per acre in the double-cropped soybeans (73.64 bu/A).
