Corn (Rio Grande do Sul, Brazil)

Study details

• Research institution: Physioatac Consultoria Agrícola
• Researcher: Gabriel Schaich
• Date: September 2019 – February 2020
• Location: Cruz Alta, Rio Grande do Sul, Brazil
• Soil: pH 5.9
• Fertilizers: Granubor ^®, ulexite, and and KCl compacted + boron (0.5% B + 58% K₂O)
• Crop variety: Hybrid AG 9025 Pro3
• Trial design: Randomized complete block design with 4 reps. Treatments were soil applied in September 2019.

Results

At a boron rate of 1 kg/ha, Granubor resulted in the highest grain yield, with advantage of 295 kg/ha over the control. Also Granubor resulted in the highest grain yield, with a yield advantage of 169 and 293 kg/ha over the ulexite and KCl compacted + boron treatments, respectively.
