Methodology

Methods and Agronomic Information

The variety, Federal 165RR2Y was planted in the North part of the field and Curry 1103 in the South part, both on 5/20 in 30” rows.  Hail damaged the crop about a month later and again on 7/17.  A single row of a cover crop mix containing 30% annual ryegrass, 20% crimson clover, 20% forage radish, 20% turnip, and 10% dwarf essex rapeseed was seeded at 6 lbs ac-1 between the soybean rows in each treatment strip (Figure 1) on 8/6 at R3.  The field received approx. 14.2 in. of rain from June 1 through August 31.

Results

Results

On average, the nine treatment strips yielded 3.3 bu ac-1 higher than the estimated yield of those same strips without the seed treatment.  This estimate was calculated from data surrounding both sides of each strip..  However, the treatment appeared to increase yields on some of the uplands and reduce them in lowland areas.  Cover crop biomass yields in the lowland areas were between 500 and 1,000 lbs ac-1 at soybean maturity, but did not interfere with harvest.
