Effect of Seedling Age on Growth and Yield of Local Aman Rice Varieties in the Low Land Area of Southwestern Coastal Bangladesh

Suitable variety and optimum seedling age are important agronomic decisions for better productivity of rice particularly in the low land area. A field experiment was conducted at Agrotechnology Discipline, Khulna University, Khulna, Bangladesh during aman season (monsoon) to investigate effect on growth, yield attributes different local varieties coastal area southwestern Bangladesh. Four ages (15, 30, 45 60-days old) three (Ranisalute, Jatai balam Basful balam) were used as experimental treatments. The arranged a factorial randomized complete block design replicated thrice. Earlier (15 days) substantially influenced growth parameters but significantly higher with 30-days old seedlings yet no significant variation 45-days seedling. produced 8-32% more grain than other ages. Among varieties, highest plant height, components achieved from Ranisalute only 3-5%. From findings this experiment, it can be concluded that use is
