| Abstract | ||
| A field experiment was conducted during 2007 and 2008 rice seasons at Al-Mishkhab Rice Research Station at Al-Najaf province. The objective was to know the effect of different seedlings age on growth plant dynamic and yield and component of yield of two rice cultivars (Anber33 , Jasmine). The design was used split plots with RCBD arrangement in three replications. Cultivation practices managed according to System of Rice Intensification(SRI) methods. The results of experiment showed that the young seedlings (8 , 10 , 12) days old gave highest average grain yield than the late transplanting of seedlings (30 days old) for both seasons (2007,2008). In the first season, the results indicated that the highest average grain yield was 7161 kg.ha-1 for 12 days of seedlings old for both cultivars , and the lowest average grain yield was 4749 kg.ha-1 for 30 days of seedlings old. In the second season, the highest average grain yield was 6827 kg.ha-1 for 8 days of seedlings old , and the lowest average grain yield was 4625 kg.ha-1 for 30 days of seedlings old for both cultivars. The plants growth and essential activities performance of younger seedlings were the best for both seasons, the early transplanting of seedlings with(8, 10, 12) days old gave highest of plant height, the plant gave biggest ability with (12, 15) days seedling old, and the highest leaves number with(12, 15) days old | ||
