Field Study

Vitazyme on Soybeans – 2013-Ukraine

The researchers concluded,

1. Soybean plants with either one or two foliar treatments (1 L/ha, and 1 L/ha + 0.5 L/ha) of Vitazyme, on top of a 1 L/tonne seed treatment, provided a yield increase of 0.52-0.57 tonne/ha, or 20-22%, and a profit of 1,850-2,050 UAH/ha.

2. The impact of Vitazyme applied in 2012 on soybean yield provided a yield increase of 0.21 tonne/ha (8%), and a profit of 840 UAH/ha.

3. Vitazyme application provided soybean seed quality improvement; the weight of 1,000 seeds increased by 4-8 grams, grain density by 8-17 grams/L, and crude protein by 0.8-2.2%.

4. Vitazyme application on seeds and plants, and carryover effects from 2012, provided an increase of nitrogen-fixing nodules of 9.7-18.6 nodules, and an increase of soybean leaf area of 0.4-1.3 m2 per one square meter of the plot (m2/m2).

Researcher: V. V. Plotnikov
Variety: Khutorianochka
Soil type: ash gray soil
Experimental design: A small plot soybean study was conducted, with four replications, to determine the effect of Vitazyme on bean yield, profitability, quality, and plant characteristics. One treatment was on soils treated with Vitazyme in 2012 to evaluate the carryover effect.
Fertilizer treatment: All phosphorus and potassium fertilizers were applied the fall of 2012.
Vitazyme treatments: The seed treatment was applied May 2, at planting time, the third trifoliate soil and foliar spray on June 11, and the branching soil and foliar spray on June 18.
