Soy (Rio Grande do Sul, Brazil)

Study details

• Research institution: Physioatac Consultoria Agrícola
• Researcher: Gabriel Schaich
• Date: November 2019 – March 2020
• Location: Cruz Alta, Rio Grande do Sul, Brazil
• Soil: pH 5.6, red latosol soil type (38% clay)
• Fertilizers: Granubor ^®, ulexite, and KCl compacted + boron (0.5% B + 58% K₂O)
• Crop variety: BMX Zeus IPRO
• Trial design: Randomized complete block design with 4 reps. Treatments were soil applied in November 2019.

Results

At a boron rate of 1.3 kg/ha, Granubor resulted in the highest grain yield, with advantage of 322 kg/ha over the control. Also, Granubor resulted in the highest grain yield, with a yield advantage of 59 and 212 kg/ha over the ulexite and KCl compacted + boron treatments, respectively.
