Currently, production of rice in areas of the southern coastal central provinces, which are subject to difficult conditions, is limited to only a few rice varieties. Farmers in these regions produce existing rice varieties which, combined with high costs of production, results in low economic efficiency. In order to increase farmers’ income and improve average rice yield in the region, a greater number of suitable rice varieties need to be adopted. Research results for the year of 2007-2009 identified the varieties DH6, SH2, QNT1 as being suitable for unirrigated areas and areas experiencing acidified soil. These varieties achieved a yield of 6,0-7,0 tons/ha with rice quality considered high, owing to the varieties’ highly palatable nature and reduced susceptibility to disease during the region’s winter-spring season and autumn season.
