OBSERVATIONS
SUMMARY
During field scouting, the northern half of the strips seemed to have a darker green color when compared to the southern strips that had a much lighter pale green. Northern strips also seemed to have a more consistent stand. The plots were virtually weed free all season long. Some soybean lodging was experienced in the higher productivity ground.
•
The strip intercropping approach continues to show some promise as in years past. The lack of timely rain and short season hybrids/varieties definitely had an effect and held this crop back.
•
As you see, the northern portion of the strips continued to produce more yield as compared to the southern portion. Continued investigation is needed to determine the cause of this.
