Vitazyme on Cotton – 2011, San Angelo, Texas
This irrigated cotton trial at San Angelo, Texas, showed that two Vitazyme applications and one BR-61 application increased bolls by 4%, or 43 lb/acre more lint if the yield across the treated part of the field was increased by this much.
Researcher: John and Matthew Wilde, with Eddie Pearson
Variety: FiberMax 9170 B2F
Soil type: unknown
Experimental design: Experimental design: A 60-acre cotton field was divided into a Vitazyme + BR-61 treated area, and the remainder of the field was farmed conventionally. The purpose of the trial was to evaluate the effect of the products on cotton yield and growth characteristics.
Fertilizer treatment: At planting, 5 gal/acre of a 32% N solution; at first square, 5 gal/acre of a 32% N solution; at first bloom, 5 gal/acre of a 32% N solution; at full bloom, 10 gal/acre of a 32% N solution; at full bloom, 10 gal/acre of a 32% N solution. BR-61, a Vital Earth soluble fertilizer (9-58-8% N-P2O5-K2O + 0.12% Fe, 0.05%Mn, and 0.05% Zn) was applied through the irrigation water at 8 lb/acre at late bloom.
Vitazyme treatments: 8 oz/acre (0.7 liter/ha) twice during the growth cycle
