Abstract A system of plant, soil, water and nutrient management for irrigated rice developed in Madagascar has been yielding 5, 10, even 15 t ha−1 on farmers' fields where previous yields averaged around 2 t ha−1. This is achieved using whatever variety of rice the farmer is already using and without having to utilize chemical fertilizer or other purchased inputs. This system, known as SRI, shows that alternative management practices, creating optimal growing conditions for plants, can bring out previously untapped genetic potential. It also shows that the practices farmers have used for centuries may not always be the best in agronomic terms.
