Yogyakarta's School of Agricultural Technology at Gadjah Mada University (FTP UGM), together with farm groups from across the province, have discovered a new rice planting system they call the System of Rice Intensification (SRI).

The SRI uses seedlings less than 15 days old, planted at a depth of between two and three cm, spaced at least 25 cm apart and a single seedling to a hole.
