Rice (Vietnam)

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.
• Crop variety: OM5451
• Trial design: Randomized complete block with four repetitions

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.
