In humid Bangladesh, finding reliable vegetable seed can be a challenge — a situation that can ruin a crop before a farmer’s hard work even begins. But Bangladesh seed companies are rapidly adopting a new technology that can improve seed germination and plant vigor, through improved seed processing and storage. Called “drying beads,” this reusable tool can help seed companies provide farmers with higher quality seed, improving the local seed industry and helping farmers maximize the potential of their own hard work.
Many of the country’s leading vegetable seed companies have adopted drying beads through a multi-part training led by Rhino Research and supported by the Feed the Future Innovation Lab for Horticulture, based at the University of California, Davis. Participating organizations include Lal Teer Seed Limited, Metal Seed, Getco, A. R. Malik & Co., Ispahani Agro Limited, Bangladesh Agricultural Development Corporation and others.
“We concluded that these beads are drying our seeds faster and deeper, obtaining a better quality that results in a longer storage potential, and all this with lesser costs,” said Tabith M. Awal of Lal Teer Seed Limited in Bangladesh. “Therefore Lal Teer made the executive decision to move ahead with implementing these beads for all our seeds and crops as soon as possible.”
This year, more than 200 tons of vegetable seed have been dried and stored with drying beads — helping an estimated 100,000 farmers in Bangladesh access quality seed.
Apricots offer farmers in southern Tajikistan a profitable opportunity — particularly when dried for export to foreign markets.
In a region where 10 percent of the population lives on less than $1.25 per day, an international team led by U.S. scientists is digging into a new research project to help, advancing the science behind growing, drying, and selling these golden fruits.
Long history, new opportunities for apricot farmers in Tajikistan
Apricots have a long history in Tajikistan, as part of a region that is rich in apricot biodiversity (and potentially where the fruit originated). While apricots are grown widely across the country, farmers in northern Tajikistan in particular have well established commercial production and drying operations. More than 80 percent of Tajikistan’s dried apricots are exported to Russia, the world’s largest importer of dried fruit.
Elizabeth Mitcham, director of the Feed the Future Innovation Lab for Horticulture and a UC Cooperative Extension specialist in postharvest biology for the UC Davis Department of Plant Sciences, represented the DryCard during the competition.
How do you see dryness? Solar drying is a simple way for smallholder farmers to preserve their harvest, but knowing when food is dry enough to store is complex. UC Davis researchers invented a low-cost, easy-to-use tool that farmers can use to measure food dryness, called the DryCardTM.
In developing countries, mold growth on dried foods is a pervasive problem, which can mean postharvest losses for farmers and unsafe foods for consumers. When mold grows it reduces the market value of dried foods, meaning less income for farmers. But moldy foods can also contain toxins that suppress the immune system, increase disease rates, and cause lifelong stunting in children.
Trip to market inspires a solution
Improving the postharvest drying process for smallholder farmers is something UC Davis scientists Michael Reid and James Thompson think about often. As UC Cooperative Extension specialists, Reid and Thompson have a history of working together in California and around the world on postharvest technologies, including a design for a more efficient solar dryer.
Last summer Reid led a Horticulture Innovation Lab workshop in Tanzania to provide training in postharvest handling of fruit and vegetable crops. The class visited the local market and tested the moisture content of some of the dried foods for sale. They found huge variation between the moisture contents of dried foods — over half were insufficiently dried and susceptible to mold.
