Study details

• Research institution: AgrariaFoundation for Agricultural Research (FAPA)
• Date: 2020-2021
• Location: Candoí, Paraná, Brazil
• Soil: Aluminic Oxisol; pH (CaCl₂) = 5.07
• Fertilizers:
  • Crop B: Granubor^® and ulexite before planting barley (0, 0.43, 0.75, and 1.5 kg B ha^-1).
  • System B: Granubor and ulexite (0, 0.86, 1.5, and 3.0 kg B ha^-1) before planting barley (50%), and before planting soybean (50%), in successive barley-soybean rotation with no-tillage practice.
  • Granubor and ulexite were blended with NPK fertilizer before planting.
• Crop variety: Daniele
• Trial design: Randomized complete block with three repetitions.

Results

Application of 3 kg Granubor ha^-1 (system B fertilization | 50% of the dose before planting barley + 50% of the dose before planting soybeans), gave the highest barley grain yield compared to the control and acidulated ulexite source.
