Productivity and nutritional quality of radish under different planting geometry

The Korean radish (Raphanus raphanistrum subsp. sativus) cvs. BDM, CDM, HGM, HTM, JKM and SJM, and a standard Vietnamese cv. R13 were evaluated for adaptability, yield and quality as affected by planting geometry in Vietnam over two growing seasons. In first season, radish cultivars were planted under the planting geometries 30 × 15 cm, 30 × 30 cm, or 60 × 30 cm. The Korean radish cultivars produced better yield of good quality than the Vietnamese cultivar. The Korean and Vietnamese cultivars had better root yield with the planting geometries of 30 × 15 cm and 60 × 30 cm, respectively. The Korean radish cultivars SJM, JKM and BDM, performed well in Vietnam, in terms of yield and quality than the Vietnamese cultivar. Therefore, Korean radish cultivars may be grown in Vietnam.
