Abstract: | The objectives of this research were to investigate the effect of rice straw management and application of different types
of organic fertilizer on growth and yield of dry direct-seeded rice grown under rainfed conditions. The experiment was conducted
in a farmer’s field at Muang Yai village, Khon Kaen province in 2005. A split-plot design was used, with the main plot under
rice straw management (incorporating into the soil and burning), and sub-plots by type of organic fertilizer (green manure,
cattle manure and powder organic fertilizer) and one plot under no-fertilizer application. It was found that rice straw incorporated
into the soil had no significant effect on grain yield when compared with the effect of burning. Organic fertilizer of cattle
manure and powder organic fertilizer significantly increased grain yield over that of green manure and no-fertilizer application.
