Wet season rice sown early by 20 June could out-yield subsequent delayed sowings by 69.18% (5 July) and 290.86% (20 July) under complete submergence. Straw yield also followed the similar trend. Harvest index of early sown rice was significantly superior over the corresponding indices of rice sown by latter two dates. Grain and straw yields were higher in cv. Pratikshya than Hybrid Ajay under post-flood agro-ecological situation. Among all treatment combinations, the highest grain yield could be harvested in Pratikshya sown early (20 June) under modified System of Rice Intensification (SRI) whereas Ajay sown late (20 July) under SRI had yielded the lowest grain.
