The roundtable discussion underlined the need to harness the opportunities offered by the System of Rice Intensification (SRI) and its extensions to crop production in many areas. This may help in substantially reducing the need for embedded subsidies in every grain of rice while achieving increases in yield by 15 per cent to 40 per cent or more over present conventional methods. In India about 1.7 million farmers are estimated to have adopted the technique on more than 7.5 lakh hectares across 160 districts, without any major project funding so far. Tamil Nadu and Tripura are the leading states for adoption of SRI, but many others are following suit.
SRI operates on the basis of modifying management practices (for plants, soil, water and nutrients) instead of requiring a change in variety (new seeds) or other external inputs. The methods work well with new varieties, but also farmers’ present varieties, including indigenous ones; they can be used with chemical fertilizer, but biomass amendments to the soil give best results. With SRI management, crops are usually more resistant to pests and diseases, so chemical protection is less necessary, and Integrated Pest Management protection is most compatible with SRI. The methods were developed for irrigated rice production, but are being extrapolated to upland rice and even other crops. The principles on which SRI is based are well established now by scientific evaluation.
The relevance of the national consortium on SRI was highlighted -
The roundtable put forth the need for a national program and policy on SRI and raised the following concerns -
The SRI roundtable also put forward the strategy for SRI in the twelfth five year plan -
