7. SRI : Practices and Principles SRI’s package of practices involving sustainable management of plants, soil, water and nutrients resulting in higher production with reduced external inputs could be extrapolated to other crops RECOMMENDED PRACTICES PRINCIPLES 1 Transplanting of young seedlings Utilizing early vigour of young seedlings 2 Wider spacing Reducing competition for light and nutrients 3 Single seedling per hill Reducing external inputs in form of seeds, water, etc 4 Alternate wetting and drying with shallow irrigation Keeping soil from becoming anoxic 5 Inter-cultivation with weeder Promoting healthy root growth 6 Addition of organic matter Increasing soil microbial activity and enhancing soil organic matter

13. Comparative Crop Cutting Results of 2009 The grain yields of conventional crop decreased by 31% as compared to a reduction of only 13% in SRI crops. In the drought year, while non-SRI yields stood close to 25 quintals per ha, the SRI yields were about 48 quintals per ha (an average increase of 92%). S.
