Manual Rotary Weeder


Problem that technology is supposed to solve :

Weeds are posing huge challenge for farmers especially those engaged in rice production, which is the country’s staple food. This technology will ease the burden of weed control on farmer especially women farmers who are normally responsible for weed control on the farm.


Technical characteristics of the technology :

The manual rotary weeder is :
- Economical, because it reduces the working time

- Ecological, because it does not use fuel

Economic characteristics of the technology

- Acquisition cost :

The rotary weeder will cost approximately Le 1,500,000 (one million five hundred thousand Leones -$150 ).

- Economic profitability :

The technology is still in the testing and adaptation stage, but once the technology is scaled up, farmers would be willing to pay up to 200,000 ($200).

- Comparative advantage :

The technology has advantage over motorized weeders because it is both economically and environmentally friendly, as it does not use fuel, and it is more efficient than hand weeding.

Limits of the technology :

The crops should be row planted with at least 25cm apart which local farmers find it difficult to do. The rotary weeder is 100% mental, which made it prone to rust and corrosion when it meets with water. Also movement in clay soils is difficult because the weeder easily get stuck in the soil.
