Methodology

METHODOLOGY:

Stratego YLD fungicide was applied at 4.5 oz/a on July 28th @ R1, with and without, 14 oz/A Fortalis, a foliar N product (8-0-0).

The treatment named High Fertility received Urea, Potash and AMS fertilizers. 200 lbs N/a as urea (46-0-0), 100 lbs K2O/a as Potash (0-0-60), and 50 lbs N/a as AMS (21-0-0-24S) were broadcast May 10th @ pre-emergence .

MegaFol a foliar fertilizer product (3-0-8) was applied at 16 oz/A on July 7th @ V4, with and without, UAN (28-0-0) applied at 10 gpa with 10 gpa water.

Vinegar= 5 gal/a concentrated Vinegar (35%) applied with 15 gpa water on July 7th @ V4.

 

Results

RESULTS:

The high fertility treatment, the combination of Urea, Potash and AMS, yielded significantly greater than the control by a gain of 6.4 bushels. The results where significant at the 90% confidence interval. The results show potential for nitrogen fertilizer use in soybeans.
