Problem

Lack of cost-effective devices to accurately assess optimum moisture content of grain for storage or marketing

}

Solution

Provides accurate moisture reading thus helps solve issue of underdrying that can result in fungal growth and aflatoxin production. also solve problem of overdrying that wastes scarce resources

Target Beneficiaries

smallholder farmers and small-scale traders of grains

Mission and Vision

Smallholder farmers and small-scale traders harvesting, drying, storing, selling and consuming safer, better quality maize and other grains.

Innovation Description

A simple, low-cost method to determine moisture content of maize was developed by researchers at Purdue University. The method is based on a low-cost Mini Digital Hygrometer (retailing for $2.00 in the USA) that provides humidity and temperature measurements. An equilibrium humidity reading of 65% indicates a moisture content of 12.5 to 13.5% (conditional on temperature, typically 21-33C). Purdue, CYMMYT, and KALRO have partnered with Bell Industries, a local company in Kenya to test market the sale of hygrometers in East Africa. Purdue is working with ISRA and the private local company SEDAB in Senegal to test and market the sale of hygrometers in West Africa.

Competitive Advantage

Cheaper than traditional moisture meters which cost > $100. More accurate than strips that change color based on moisture level.

Planned Goals and Milestones

1. Continue developing the supply-chain i) work with women and youth groups in Kenya and Senegal to sell hygrometers 2. Create more awareness among smallholder farmers and small-scale traders 3. Include hygrometers as part of a "post-harvest" package that includes i) training, ii) tarps and other low cost dryers, iii) hygrometers and i) hermetic bags for a full set of solutions for drying and storage
