Abstract: Research on Nursery management in rice carried out in different parts of South East Asia have been reviewed with findings that application of balanced nutrition in the form of inorganics and organics in rice nursery produced healthier seedlings as compared to organic and inorganic alone. Application of nitrogen from recommended dose up to 100 kg ha^-1 in the nursery along with suitable doses of P₂O₅ and K₂O was beneficial in recording higher growth, yield attributing characters and yield of medium or late duration rice under submergence condition. Application of N at higher dose (basal and top dressing) without P₂O₅ and K₂O was detrimental under flash flood condition. Use of P₂O₅ and K₂O up to 40 kg ha^-1 along with different doses of N recorded higher growth, yield attributes and yield. The effect of seedling density in nursery under submergence condition was also investigated by several workers. Many of the workers reported that lower seeding (25 to 50 g m^-2) was superior in recording the higher seedling growth and better performance during post flood period. The older seedlings up to 45 days old performed better in terms of post flood survival, growth and yield of rice as compared to 25 to 30 days old younger seedlings.
