The LaRue County Extension Service annually conducts corn and soybean variety plots in cooperation with a local farmer and participating grain dealers. Recently, we looked at this year’s corn plot results. This week we will look at the soybean results. They, too, were on the Kevin McCubbin farm.
The soybean plot was planted June 17 and harvested Nov. 11. All varieties were Roundup Ready Group III or IV. The field was planted no-till following corn in Nicholson soil. The beans were planted in 15-inch rows at about 160,000 seeds per acre.
The yields were adjusted to 13 percent moisture. Yields were generally reflective of this year’s crop in the county. Last year’s winner, AgVenture 43A2RRSTS was the check or standard variety and averaged 46.7 bushels per acre.
Actual yields and then adjusted yields were calculated. Ranking was done by adjusted yield. The top yielding variety was Asgrow AG4232RR2Y with an adjusted yield of 59.8 bushels per acre, followed by Pioneer 94Y61 and Asgrow AG4832RR2Y at 51.3 bushels per acre. Other varieties (in order by adjusted yield) were: Channel 4205 R2, Stine 4782-4, Southern States RT4808N, AgVenture 49X1RR, Beck’s 445NR, NK S46-A1, Armor 47R33, Channel 4502, NK S38-K6, Beck’s 477NR, Armor 44K6, DynaGro 32RY39 RR2Y, DynaGro 36C44 RR, Stine 43RB82, Pioneer 93Y92, Southern States RT4370N, and AgVenture 40A2RR.
Complete results of both county extension corn and soybean tests are available at the Extension Office. The reports also list yields by actual yield, field location and multiple year data.
