This document discusses the System of Rice Intensification (SRI) method of rice cultivation and the role of agricultural engineers. SRI aims to maximize rice production through practices like younger seedlings, wider spacing and less water. It encourages farmer participation and innovation. Agricultural engineers can help develop machinery to support SRI, such as transplanters for single or double seedlings, mechanized markers for spacing, and manual or powered weeders. Future work includes developing transplanters and self-propelled weeders suitable for SRI methods.

3. What is SRI ? “ SRI is now being seen as more than a set of practices (young seedlings, wider spacing, less water etc), but really as an opportunity for maximising production potentialities and even as a philosophy. It encourages farmer participation and innovation to make it more appropriate to local conditions and more owned by the users”.
