Soy and Corn (Brazil)

Study details

  • Date: 2017-2019
  • Location: Fundação MS, Mato Grosso do Sul, Brazil
  • Soil: Two locations with different soil texture: Sandy (Navirai) and clay (Maracaju)
  • Fertilizers: For both crops, boron was tested at rates of 0, 1, 2, and 4 kg B ha-1 using Granubor® (sodium tetraborate) as the fertilizer source
  • Crop: In both locations, soybean was planted during the summer (rainy season) followed by winter corn (safrinha)
  • Trial design: The fertilizer was broadcast-applied 1 day before planting. In the case of corn, two different times of boron fertilizations were tested:
    1. 100% at pre-planting of soybean
    2. 50% at pre-planting of soybean and 50% at pre-planting of corn

The preliminary data from the 2017/2018 growing season showed no statistical difference for the time of boron application for corn. The preliminary data from 2017/2018 showed statistical grain yield benefit of 384 kg ha-1 of 1 kg B ha-1 over control for soybean in the Maracaju location. The grain yield difference in the Navirai was of 264 kg ha-1 but not statistically different.
