How drying beads work, in a new SciDev.Net video

Reporter Giovanni Ortolani visited with Horticulture Innovation Lab partners in Bangkok, Thailand, recently to learn about how farmers in humid climates can better save seed using drying beads. His video (below) and article “How seed-drying beads can empower farmers in the tropics” were published this week on SciDev.Net, a news website focused on science and technology for global development.

When stored in hot, humid conditions, vegetable seed deteriorates rapidly — lowering germination rates and farmers’ yields. Ortolani interviewed Patcharin Taridno, senior manager of seed technology with Rhino Research, about how the company’s zeolite-based “drying beads” can help farmers better dry seeds for storage by reducing relative humidity.

‘Dry chain’ partnership helps farmers store seed better

A partnership between university scientists and a private technology company has sprouted both new concepts and new tools that can help vegetable farmers in developing countries access better seeds.

For many smallholder farmers, buying and trading vegetable seeds can be risky. The benefits of purchasing seed can be high, with improved crop varieties offering disease resistance, increased vigor and improved taste. But the risks of receiving poor-quality seed are also significant, particularly in tropical climates. Seed will deteriorate rapidly if it is not properly dried and stored. The resulting poor germination reduces yields, which for vegetable farmers can mean staggered harvests and inconsistent crop quality.

“If you buy seed and it’s all dead, you aren’t going to buy very much more seed,” says Kent Bradford, seed biologist at the University of California, Davis. “To get improved varieties into farmers’ hands, you must have a system where people can buy and trade seed successfully.” Continue reading ‘Dry chain’ partnership helps farmers store seed better
