Barley (Paraná, Brazil, Granubor)

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.
