Summary

Increased labour costs and area under irrigation, the development of modern early-maturing varieties and improved fertilizer and weed management techniques have encouraged many farmers in the Philippines, Malaysia and Thailand to switch from transplanted to direct-seeded flooded rice culture. This paper summarizes the development and spread of the technology for direct-seeded flooded rice in southeast Asia and the contribution made by research at IRRI and by national programmes. It covers research on crop establishment, varietal requirements, fertilizer management, weed control and economics and examines the advantages and disadvantages of direct-seeding compared with transplanting.
