摘要：

A study was conducted under system of rice intensification (SRI) and non-SRI environment. A total of 195 and 77 technological demonstrations were conducted on SRI and non-SRI transplanting methods in various rice ecosystems. Mean rice yield of the technological demonstrations conducted on SRI was 5716 kg/ha, which was more than the mean yield of 3742 kg/ha under farmers' practice. However, in non-SRI demonstrations, the mean rice yield was 4136 kg/ha, which was more than the mean yield of 2941 kg/ha recorded under farmers' practice. Further, the mean rice yield of the SRI demonstrations was higher than that of the non-SRI demonstrations. The SRI technique is, .thus, recommended for dissemination among the farming community for increased and sustained rice production.
