The document discusses the collaborative research by Oxfam and Rajarata University of Sri Lanka on the development of three-row weeders for effective weed management in paddy fields. It highlights different types of modified weeders, detailing their specifications, weights, and intended weed control functions. The findings are based on practical field comparisons of the weeders in Sri Lanka, focusing on improving soil structure and aeration.
