Corn (Paraná, Brazil)

Study details

• Research institution: Fundação ABC
• Researcher: Gabriel Barth
• Date: 2014 – 2016
• Location: Arapoti, Paraná, Brazil
• Crop variety: P 30F53H

Specific details study #1

• Soil: pH 5.2
• Fertilizers: Solubor^® Flow
• Trial design: Randomized complete block design with 4 reps. Treatments foliar-applied at V4/V5 and V8/V9.

Study #1 results

The foliar application of Solubor Flow tended to increase corn grain yield compared to the control. At a rate of 1.5 kg B/ha, the yield increase was 210 kg/ha.

Specific details study #2

• Soil: pH 4.7
• Fertilizers: Boric acid and Solubor^®
• Trial design: Randomized complete block design with 4 reps. Treatments foliar-applied at V4.

Study #2 results

The study was conducted for only one year. The foliar application of boron tended to increase corn grain yield at all rates. Solubor showed a better performance than boric acid at all rates even though not statistically different.

Specific details study #3

• Soil: pH 5.2
• Fertilizers: Granubor^® and ulexite
• Trial design: Randomized complete block design with 4 reps. Treatments soil-applied at planting.

Study #3 results

The study was conducted for only one year. The addition of boron had a minimum impact on corn grain yield. Granubor showed a slightly better performance than ulexite at all boron rates even though it was not statistically different.
