Soy (Sinop, MT, Brazil)

Study details

• Research institution: NEMABIO, Agronomic Research
• Researcher: Dr. Claudinei Kappes
• Date: 2022/23 and 2023/24 growing seasons
• Location: Sinop, MT, Brazil
• Soil: Dystrophic Red-Yellow Latosol (Oxisol); clay 40.8%; sand 51.0%; silt 8.2%
• Soil information: pH 4.9 (CaCl₂); OM 19.6 g/dm³; P 9.6 mg/dm³; K 34.5 mg/dm³; S 16 mg/dm³; Ca 2.1 cmolc/dm³; Mg 0.6 cmolc/dm³; B 0.14 mg/dm³; Cu 1.5 mg/dm³; Mn 2.0 mg/dm³; Zn 5.1 mg/dm³; Fe 37 mg/dm³
• Fertilizer: Granubor ^®
• Crop variety: BMX Bônus IPRO
• Trial design: Randomized complete block with four repetitions.

Results

The results obtained allowed us to conclude that:

• The application of 2.0 kg/ha of B via Granubor in soil with low initial availability of the element led to higher soybean yield (cv BMX Bônus IPRO), whose percentage increase was 10.6% in the season 2022/23, compared to the treatment control
• The application of 1.5 kg/ha of B via Granubor in soil with low initial availability of the element led to higher soybean yield (cv BMX Bônus IPRO), whose percentage increase was 8.2% in the season 2023/24, compared to the treatment control
• Applications of increasing doses of boron linearly increased the levels of the element in the leaf and soil, where the lowest values were seen in the treatment control
