This System of Rice Intensification was discovered almost by accident in 1983-84. Due to a lack of time for letting rice seedlings grow for 30 days before being transplanted, students in a farm school at Antsirabe (1,500 meters a.s.l.) were obliged to use their very small nursery twice within a month. This meant that some seedlings had to be transplanted after only 15 days.
