Researcher: Gary Burkey
Variety: Flexseed 303 Triple-Stack
Soil type: mucky sand
Experimental design: A field was treated entirely with Vitazyme on the seeds at planting, and a portion of the field was foliar treated to determine the effect of this later application on crop yield.
Fertilizer treatment: Before planting: 150 lb/acre potassium chloride (0-0-60% N-P2O5-K2O); 100 lb/acre diammo- nium phosphate (18-46-0% N-P2O5-K2O). At planting: 4 gallons/acre 3-18-18% N-P2O5-K2O on the seeds at planting. Sidedressed on June 18, at 5-feet plant height: 40 gallons/acre 28% N.
Vitazyme treatments: (1) 13 oz/acre on the seeds at planting, with 3-18-18% N-P2O5-K2O over all areas;
(2) 13 oz/acre foliar over one portion of the field, on June 18
