Study details

  • Date: 2018 - 2019
  • Location: Cuu Long Delta Rice Research Institute, Mekong Delta, Vietnam
  • Soil: pH of 5.25 and boron content of 0.39 mg kg-1
  • Fertilizers: The treatments consisted on different boron rates (0, 0.9, 1.3, and 1.5 kg B ha-1) using Granubor® as the boron source. Treatments were applied 7 days after rice transplanting.

Results

For both years, the application of 10 kg Granubor ha-1 (1.5 kg B ha-1) gave the highest rice grain yield compared to the control. In 2018, the control (no boron applied) yielded 3.9 Mg ha-1 while the application of 10 kg Granubor ha-1 yielded 4.3 Mg ha-1. In 2019, the control yielded 6.1 Mg ha-1 while the application of 10 kg Granubor ha-1 yielded 6.7 Mg ha-1.

The lower yield level in 2018 happened due to excessive rain. These results show an average yield increase of 10% by applying 10 kg Granubor ha-1.
