Meeting World Demand for Rice

Half of the world’s population—nearly 3.5 billion people—depend on rice for more than 20% of their daily energy requirements. In the Asia Pacific region, rice is consumed at nearly every meal, and is essential for food stability. Growers in these countries must continually explore ways to improve production and achieve a high-quality, nutritious crop.

Vietnam is one of the largest rice producers and exporters in the world. Nearly 90% of the country’s arable land is used for rice cultivation. As global demand for high-quality rice increases, more growers are focusing on specialty varieties offering a higher profit margin on the world market.

In Vietnam, as in many Southeast Asian countries, most rice-based cropping systems are grown on high pH and alkaline soils with low boron content and very little organic matter. Extreme rainfall and flooding during monsoon season can also cause leaching of essential micronutrients, exacerbating the problem. These conditions reduce the availability and uptake of boron into grains, limiting rice productivity and impairing grain quality.

Featured Regional Crops

Cocoa
One of the first signs of boron deficiency in cocoa is profuse chupon formation and the appearance of a few curled leaves which will be almost normal green in color.

Soybean
Boron fertilization of soybeans has been shown to increase grain yield at many locations in several states. University researchers have found yield increases ranging from 5 to 18 bushels per acre.

Rice
In rice plants, boron does not move throughout the plant. Because it doesn't move to new growth, boron deficiency symptoms usually appear first on young leaves.

Improve Soil Conditions with Boron Supplementation

Correctly diagnosing boron deficiency in rice and applying high-quality boron fertilizer can improve the sustainability and productivity of rice production systems throughout Southeast Asia. Field studies have shown that the application of boron substantially improves rice grain quality, resulting in a lower percentage of chalky grain—which not only affects the appearance of rice but also causes grains to break during the milling process.
