Mosaic Soybean Study
K. Mann, K. Cooper, L. Besemann and H. Eslinger
MATERIALS AND METHODS
Soil: Embden loam and Gardena Loam; pH = 6.9; 2.8% organic matter; soil N 77 lbs/acre; soil P  and soil K was very high; soil S was medium.
Previous crop: 2015 – field corn.
Seedbed preparation: Spring conventional tillage.
Hybrid: Northrup King S10P9
Planting: May 19 in 30-inch rows.
Plots: Plots were 25 ft long by 10 ft (4 rows) wide. The study had four replications.
Fertilizer: Broadcast and incorporated treatments (see Table 1) May 18.
Irrigation: Overhead sprinkler irrigation as needed.
Pest control: Spartan Elite (22 oz/acre) May 20, Select Max (12 oz/acre) + NIS (1 pt/100 gal) + Interlock (4 oz/acre) June 13 controlled weeds.  Endura (5.5 oz/acre) July 15, controlled disease.
Harvest: October 3 with a plot combine.  Harvest area was the center two rows, approximately 21 feet long.
