  1. STATUS OF SRI CULTIVATION AND ITS FUTURE PROSPECTS IN INDIADr. M.C. Diwakar, DIRECTORDIRECTORATE OF RICE DEVELOPMENT, GOVT.OF INDIAMINISTRY OF AGRICULTUREDEPT. OF AGRICULTURE & COOPERATION, PATNA

  2. Benefits of SRI* Seed requirement reduced by 65-70 per cent* Saving of water by about 35-45 per cent* More number of tillers/productive tillers* More number of spikelets per panicle* Uniform maturity* Head rice recovery is more* Earlier maturityby 5-20 days* Healthier plants resistant to major pests and diseases* Yield advantage over the conventional method by 1.5 to 2 times* Less competition between rice plant and weeds

  3. Why a Paradigm Shift is Needed The area of rice has been declining, and its productivity is also stagnating. There is fear among the scientific community that the country may not be in a position to feed India’s citizens based on the present growth rate and current trends of productivity of rice. The Green Revolution was successful for making our country self-sufficient in foodgrain production. However, the declining trend of food grain production during the past decades has become a great concern. The concept of Green Revolution was based on the following strategies:

  4. (i) Develop semi-dwarf high-yielding varieties and exploit their genetic potential (ii) Make them more responsive to fertiliser application (iii) Increase optimum use of inputs such as water, fertiliser, seeds, pesticides and farm implements (iv) Utilise non-monetary inputs such as timely sowing, spacing, and the timely application of fertilisers and harvesting.

  5. Strategies There is need to adopt other strategies in the present context as productivity is stagnating. Thus greater emphasis has to be given to bridging the gap between existing yields and potential yields demonstrated in the experimental fields. Appropriate strategies may be as follows: (i) Adoption of improved crop production technology and its dissemination to the farming community (ii) Popularisation of hybrid rice (iii) Promotion of System of Rice Intensification

  6. Hybrid Rice Demonstrations under SRI in Dindigul District, Tamil Nadu, 2004-05

  7. Table 8 Comparison of SRI Technology and Normal Practice in terms of Cost and Benefit Ratios

  9. Future Prospects of SRI • Biologically eco-friendly • No pollution in environment, water and soil • Increasing farmers’ income as well as enhancing their productivity • Higher benefit-cost ratio – 2.5 : 1 • Technologies lead to organic farming • Less dependence on chemical fertilizers • Minimum use of pesticides • Early maturity of crop

  10. Popularisation of SRI technologies • This technology is being popularised in countries like Madagascar, Cambodia, Zambia, India, Myanmar, China, Philippines, Indonesia, Pakistan, and Nepal. • It is being popularised in the states of Andhra Pradesh, Tamil Nadu and Tripura in almost all districts. Also State govts. in Bihar, Karnataka , Chhattishgarh , Punjab, Uttar Pradesh, Uttaranchal, and West Bengal are implementing SRI in selected districts to increase yield. To create awareness among farmers, training and demonstrations are being organised at the farmers’ field level under Macro Management of Agriculture. • SRI component has been added in the National Food SecurityMission.
