Fisher, Minnesota

Variety:  unknown

Planting date:  May 19, 2002

Soil type:  clay loam

Seeding rate:  47 lb/acre

Harvest date:  October 3, 9, and 10, 2002

Vitazyme application:  13 oz/acre with herbicide and starter fertilizer before planting

Yield results:

Control: 1,767 lb/acre
Vitazyme: 1,730 lb/acre (-2%)

Note: Due to strong soil compaction and very heavy rains early in the season, soil microbial activity in the rhizosphere was severely curtailed so that Vitazyme's active agents could not produce the growth increases that normally occur.

Fertilization:  unknown, except for some commercial starter fertilizer before planting
